The third generator was shipped in March 2014. In addition, the power plant engineering group is to supply 22 complete sets of hydropower generator excitation systems for Volzhskaya HPP by 2017. The corresponding contract was concluded in 2012. Five excitation systems have already been delivered to the plant, three of them have been put into pilot operation – those a NEW steam turbine for Zhezkazganskaya TPP in Kazakhstan The Kaluga Turbine Works (KTZ OJSC) company, member of Power Machines OJSC, has produced, tested and shipped to the customer a 60 MW steam turbine for Zhezkazganskaya TPP. The Company concluded a contract to supply the equipment to Kazakhmys Corporation PLC (Republic of Kazakhstan) in 2012. According to its terms, Kaluga Turbine Works has produced and supplied a 60 MW steam turbine. The next stages of works stipulated by the contract are installation supervision, commissioning and start-up. The new turbine is designed for the installation at the plant’s fourth power unit to replace a life-expired 25 MW turbine produced in the Czech Republic. As a result of the renovation the capacity of the power unit will increase by 35 MW. At present KTZ is producing one more 60 MW turbine designed to replace a turbine of the same capacity forming part of the fifth power unit of Zhezkazganskaya TPP. A corresponding agreement was signed with Kazakhmys Energy PLC in 2013. The start of the equipment shipment is scheduled for September this year. MEGAWATT Next Comprehensive modernization of hydraulic units Auxiliary Equipment for the Turbine Unit at Blagoveshchenskaya TPP at hydropower units No.1, No.16 and No.18. The renovation of the equipment will enable it to considerably improve its reliability and performance, as well as to increase the installed capacity of Volzhskaya HPP. Currently, Power Machines OJSC the general contractor for the Blagoveshchenskaya TPP construction project, is carrying out activities to renew engineering structures of the main building. The concern also continues manufacturing power equipment and conducts tendering procedures to select suppliers of boiler-auxiliary equipment. The master contract to construct the 2nd stage of Blagoveshchenskaya TPP on a turn- key basis was signed following an open tender in December 2013. Under the terms of the contract, Power Machines OJSC is general contractor for the 2nd stage of Blagoveshchenskaya TPP. The company is to perform construction, installation, commissioning and startup works, and is also to manufacture and supply all necessary equipment, including basic power equipment – a steam turbine with capacity of 120 MW completed a 400-ton turbogenerator stator for Kozloduy NPP in Bulgaria Krasny Kotelshchik Ships equipment for Nord Power Machines OJSC and Rusatom Service CJSC signed a contract to repair and supply power equipment for the sixth unit of Kozloduy NPP in 2013. This is the first contract concluded under the agreement signed in 2012 with the purpose of cooperating in the markets of Bulgaria, Armenia and other countries. The Taganrog Boiler-Making Works “Krasny Kotelshchik”, which is a part of the Power-Plant Engineering Concern OJSC Power Machines, has completed shipment of four hot water gas-and-oil fired boilers for 240MW boiler plant being constructed in Murino (Leningrad Region). The boilers of this type are designed for production of hot water of the temperature up to 150 °C with the purpose of its further usage in the domestic amenities heating and hot water supply systems. In compliance with the contract, Power Machines will renovate a 1000 MW turbogenerator rotor and also manufacture and supply a new turbogenerator stator to the plant including spare part kits for the turbogenerator stator and exciter. All equipment manufactured by Power Machines will be supplied to the NPP site during the second quarter of the year. The installation work at NPP is scheduled to be completed between the third and fourth quarters of 2014. Installation supervision will be provided by Power Machines engineers. The renovation will extend the life of the power unit, and the renewed generator will have an increased capacity of 1100 MW. The contract stipulating development of the design documentation required for the execution of the project, manufacture of equipment, as well as supply of low-power boilers to the customer, was concluded between Krasny Kotelshchik and Nord Company in November of the year 2013. At present all the obligations under the above contract have been fulfilled. The equipment designed by the specialists of Krasny Kotelshchik stands out for its properties from the conventional hot water boilers with output of 50, 100, 120, 180 Gcal/h. The new design implemented there was the L-type boiler arrangement, which has proved to be less metal-intensive and more competitive as compared to the P-type or tower-type arrangement. with a turbogenerator of in-house production and a coal-fired boiler manufactured at the Taganrog Boiler-Making Works Krasny Kotelshchik (operated by Power Machines OJSC), as well as power and unit transformers. So far, the project for expansion of Blagoveshchenskaya TPP capacities has passed a complete cycle of inspections and approvals. Favorable conclusions were obtained from the Main State Expert Review Board (Glavgosekspertiza of Russia) with respect to technical and cost estimating sections of project documentation, along with a building permit. The 2nd stage of Blagoveshchenskaya TPP is one of the four projects included in the RusHydro JSC investment program for construction of new power facilities in the Far East, implemented in cooperation with RAO Energy System of East JSC, in accordance with the Decree of the President of the Russian Federation. After construction of the 2nd stage, installed power capacity of the power plant is expected to increase by 120 MW up to 400 MW and its thermal capacity is expected to increase by 188 GCal/h up to 1005 GCal/h. Power Machines to renovate Kegum-2 HPP Power Machines OJSC and Latvenergo AS have signed a turn-key contract to overhaul three hydropower units of the oldest hydropower plant in Latvia – Kegum-2 HPP. The contract was signed following a tender, which Power Machines OJSC won, having submitted the best feasibility solution. The scope of supply and services of Power Machines include design effort, production and delivery of the equipment to overhaul the plant’s three hydropower units. Within the project framework Power Machines is to manufacture and deliver three max 77.8 MW hydropower turbines complete with automated control systems (ACS), as well as equipment to renovate the three hydro generators. In addition Power Machines will perform mounting, commissioning works and conduct acceptance testing of the hydropower units followed by being put into operation. The advanced hydropower equipment with increased performance and reliability will function as a part of the hydropower units of Kegum-2 HPP owing to the renovation. The time-frame for the start-ups of the renovated units is fixed for 2016–2018. Earlier, in 2013 Power Machines won a tender and signed a turnkey contract to overhaul hydropower unit No. 1 and No. 3 of Pļaviņas HPP with Latvenergo AS. As a result of the overhaul the capacity of each hydropower unit will increase by 13 MW, from 85 MW to 98 MW. Startups of the renovated units are scheduled for 2016–2017. 5 6 COVER STORY Comprehensive modernization of hydraulic units May–September 2014 | International (special) issue 1 (3) MEGAWATT The share that hydraulic power engineering has in the total scope of work carried out by Power Machines is increasing every year. While in 2013 the percentage of hydraulic equipment production was at 20% of the company's total output, it is expected to increase to up to 30% of the total output in 2014. Today the hydropower facilities with the most importance for the company include: Punta Negra HPP (Argentina), Djerdap HPP (Serbia), Pļaviņas and Kegums HPP (Latvia), Ust-Kamenogorskaya HPP (Kazakhstan), the Volga and Zhigulevsk Chain of HPPs, Cheboksarskaya HPP, Saratovskaya HPP, as well as Baksanskaya HPP in Kabardino-Balkaria, and, of course, the Sayano-Shushenskaya HPP. VLADIMIR DEMYANOV: “WE HAVE MANY COMPETITIVE ADVANTAGES IN THE HPP EQUIPMENT MARKET” 7 We discussed current conditions and prospects for the further development of hydraulic power engineering with Power Machines Chief Designer and Technical Director of Leningradsky Metallichesky Zavod, Vladimir DEMYANOV. — Vladimir Aleksandrovich, what do you think the prospects are for hydraulic power engineering in the global energy balance and, accordingly, the prospects of power-plant engineering in terms of HPP equipment production? — Basically, the global power market is fairly saturated. The exceptions are, probably, China, India, Southeast Asia, and Latin America: new capacities, including hydraulic power capacities, are still required there. Therefore, the modernization of existing power plants is currently coming to the forefront rather than the construction of new ones. This will be the main market trend for the coming years. Generally, growth in the global power market occurs in a wavelike form. The duration of each cycle is about 10 to 15 years. First, a global economic recovery occurs; it causes a growth in energy demand, so generating companies try to increase their capacities, leading to an increase in power-plant engineering orders. But then, inevitably, economic growth is suspended or there is a recession while the power-plant engineering industry is just at its height and still working on the previous orders. After that powerplant engineering falls into a recession for a while. And this will last until there is a new economic surge. Equipment for HPPs makes up about half of Power Machines’ stock of orders 8 COVER STORY Comprehensive modernization of hydraulic units Vladimir Demyanov: “The modernization of existing power plants is currently coming to the forefront” — What is Power Machines' share in the global hydraulic power equipment market? — It's quite difficult to make a precise estimate. This is due, in particular, to the closed nature of the two fastest growing markets – the Chinese and Indian markets. But generally, we are on fairly firm ground in the global market. It is enough to say that every ninth turbine in the world has been supplied by Power Machines. — How many customers does your company have abroad? Who are they? — Power Machines is globally known in the power-plant engineering market as a manufacturer of reliable and high quality equipment, and this position enables us to win tenders worldwide. For example, we have recently signed a contract for the turnkey modernization of two hydropower units for Pļaviņas HPP in Latvia. The customer is AS Latvenergo, and well-known power equipment manufacturers such as Alstom Hydro France, Voith Hydro, and Andritz Hydro GmbH participated in the tender. As a result of modernization, the output of each hydropower unit will be increased by 13 MW up to 98 МW. The renovated units will be launched in March 2016 and March 2017. We have won one other tender in Latvia — for Kegums HPP’s modernization. In accordance with the contract between Power Machines and Latvenergo, the first components (generator stator and rotor assemblies and hydraulic turbine assemblies, except for em- May–September 2014 | International (special) issue 1 (3) MEGAWATT 9 GEOGRAPHY OF POWER MACHINES EQUIPMENT SUPPLIES FOR HPPS IN 2013-2015 Svetogorskaya HPP Lesogorskaya HPP Nizhne-Svirskaya HPP Plyavinskaya HPP Rybinskaya HPP Kegumskaya HPP Cheboksarskaya HPP Zhigulyovskaya HPP Volzhskaya HPP Djerdap-1 HPP Nizhne-Bureiskaya HPP Sayano-Shushenskaya HPP Kygy HPP Charvakskaya HPP bedded parts) are to be supplied within the third quarter of 2015. And the units manufactured by us will be launched in the first quarter of 2016. This brings the total supply to three units of 71 MW each. In late 2013, an equipment supply contract was signed for Kigi HPP, which is under construction in Turkey. We are manufacturing and supplying electromechanical equipment for the HPP on a turnkey basis. The equipment includes three hydraulic turbines of 46.6 МW each, three generators of a similar output, and all of the electromechanical equipment for the turbine building and switchgear. All three hydropower units must be commissioned in 2016. These are the most recent examples. There are many projects currently in progress; for example the modernization of Djerdap-1 HPP on the bank of the Danube River in Serbia. Today, two of the power plant’s six units have been completely renovated. In line with the schedule, the modernization of yet another power unit is to be completed in early 2015. Next in line are three further units, which are to be put into operation one per year starting in 2016. After renovation, the plant's service life will be extended by 40 years and its output will be increased by 66 МW. A contract for the main turbine equipment manufacture for the Punta Negra HPP, which is currently under construction in Argentina, has been in progress since 2011. These are two hydraulic turbines of 31.6 MW each and two generators complete with excitation systems. Power Machines’ share in the Russian hydraulic power equipment market is approximately Punta Negra HPP 80% 10 COVER STORY Comprehensive modernization of hydraulic units Maximum hydraulic turbine efficiency is 96.6% Today, all the components have been manufactured and supplied to the customer and the installation process is in progress. — In accordance with the comprehensive modernization program, RusHydro is retrofitting the majority of Russia’s hydropower facilities within the company's structure. What is Power Machines' role in this process? — It is an ambitious program with a budget of tens of billions of roubles to be fulfilled within 15 years, and the scope of our participation in this program is significant. The recovery of SayanoShushenskaya HPP, after the tragedy of August 2009, is the most crucial and massive project for Power Machines within the program. Three new stationary hydropower units of a total output of 1920 MW, made by Power Machines, were launched in 2013. We are to launch the remaining 3 of 10 units within the current year, and the recovery work will be completed in general after that. We supply our equipment on a turnkey basis and this includes not only the main equipment but also control systems. The service May–September 2014 | International (special) issue 1 (3) life of the new units has been increased to up to 40 years while a hydraulic turbine's maximum efficiency is 96.6%. I think that as a result of the project’s fulfilment, Sayano-Shushenskaya HPP will become one of the most advanced power plants in Russia and will be comparable with the best projects of this kind in the world. The comprehensive renovation of the Volzhskaya and Zhigulevskaya HPPs are two more large projects within the framework of cooperation with RusHydro. Volzhskaya HPP (the largest HPP in Europe, in fact) has 22 hydropower units and Zhigulevskaya HPP has 20. The modernization program is to be completed by 2025. After renovation, the installed capacity of Volzhskaya HPP will be increased by 203.5 МW up to 2744.5 МW and Zhigulevskaya HPP’s will be increased by 147 МW up to 2488 МW. Regarding new construction projects, first of all there is NizhneBureyskaya HPP in the Amur Region. A contract to deliver four hydropower units of 80 МW each was signed between our company and RusHydro in October, 2013. Commissioning of the Nizhne-Bureyskaya hydropower units is scheduled for 2015–2016, and the design capacity of 320 МW is expected to be achieved in 2016. RusHydro is Power Machines' strategic partner and customer, but we also take part in modernization projects for power plants operated by other generating companies. For example, we have won a tender for the replacement of hydro system wheels at Ust-Ilimskaya HPP, which falls under the control of Irkutskenergo. MEGAWATT In general, when speaking about the Russian market for hydropower products, our share is about 80%. — What are the competitive advantages that Power Machines has which enable you to win tenders not only within our country, but far beyond? — First, it is our experience: it's enough to say that the Leningradsky Metallichesky Zavod produced the first hydraulic turbine as early as 1924 and has been continuously developing this line by way of constant improvement of its products. Second, it is our extensive research and development capabilities: significant investments were made in development even during the 1990s, a very difficult decade for the Russian economy. Today, we actively co-operate with the scientific community: with specialized research institutes, the Siberian Branch of the Russian Academy of Sciences, and so on. And with regard to rapid technological progress, this allows us not only to be as good as our competitors, but to be ahead of them in some things. For instance, Power Machines is the only company in the world today to produce environmentally friendly hydraulic turbine wheels which do not require the use of oil in the hub. Our equipment is furnished with an automated control system that makes it possible to switch over to unmanned power plant operation. The key feature of the unmanned operation method is that the HPP is operated on an unattended basis. The plant operation is Next Events LMZ produced its first hydraulic turbine in 1924 – 90 years ago monitored from a so-called common control centre, which sends automatic signals to the HPP personnel if there is an emergency or preemergency situation. As far as I know, this method is widely applied in Nordic countries. Unfortunately, I'm not aware of any examples of the use of the unmanned method for HPP control in Russia. As far as I know, the changeover of the Vuoksa HPP Chain to this control model is planned for the very near future. It is the HPP owners who will decide exactly when to implement this changeover. Third – and this is most important – we produce highly reliable equipment. This is probably partially due to the challenging climatic conditions inherent in some Russian regions. I mean that if our equipment is operating without any problems even in the bitterly cold weather of Siberia, it can be assimilated in any other part of the world. And finally, our products are both reliable and relatively simple in operation, which is also a very important criterion for our customers. All these factors make the equipment produced by Power Machines highly competitive and capable of beating out similar products by other manufacturers in terms of price/performance ratio.

Specialists from the joint venture will soon begin onsite installation supervision and commissioning works. The joint venture Power Machines Toshiba High-Voltage Transformers was set up in 2011 for the manufacture of transformers with a 110–750 kV voltage rating and a capacity of over 25 MVA as well as shunt reactors rated between 500 and 750 kV. The first order was for the manufacture of 110 kV / 63 MVA transformers for a new Power Machines manufacturing facility. "With this order, we were able to try out the entire transformer manufacturing cycle from design to production including all types of tests and also to check the functioning of our process equipment. Today we are absolutely ready for the commercial production of transformers," said Alexandr Mayorov, the Director of Production at Power Machines Toshiba High-Voltage Transformers. The joint venture is currently manufacturing products under the following contracts: two transformers with a capacity of 63 MVA are to be ready in the third quarter of 2014 as ordered by FGC UES for the Gubernskaya 220 kV substation being built in Tyumen — Power Machines Toshiba High-Voltage Transformers will deliver equipment and provide its installation supervision and maintenance; another project, which will comprise transformers for the renovation of Dalnyaya 220 kV substation in Vladimir Oblast, is to start soon for FGC UES. The joint venture is also participating in one of the most significant projects for Power Machines — the turn-key construction of the second stage of Blagoveshchenskaya TPP. The manufacturing of transformers for the new plant is now well under way. Latin America 13 14 ??? BRANCH ??? OFFICES Latin America May–September 2014 | International (special) issue 1 (3) Latin America — Region of Opportunities Identifying target regions and making every effort to be a key player in the power engineering market in the regions selected is one of the marketing strategy principles at Power Machines. Indeed, this is the focus of all of the group’s foreign offices. The discussion today concerns Power Machines’ activities in the power market in Latin America – the third largest regional market in the world. MEGAWATT 15 History of the relationship The penetration of Russian power machine builders into Latin American countries began back in the 1970–80s. It was in these years that the first major supply contracts for Argentina and Brazil were executed. Among the largest projects of the time was the binational Salto Grande HPP, which is located at the border between Uruguay and Argentina. Hydrogenerators with a capacity of 150 MVA each for the 14 units of the HPP (7 on the Uruguayan side and 7 on the Argentinean side) were manufactured by Electrosila, part of Power Machines. It was while working on this project that the first of Power Machines’ existing foreign offices came into being. With regard to Brazil, cooperation with the country began with the construction of two HPPs, Capivara (1972–1974) and Sobradinho (1978); Electrosila was joined for this purpose by another equipment supplier which is today part of Power Machines — Leningradsky Metallichesky Zavod (LMZ); it manufactured the turbine equipment. With regard to LMZ’s participation in supplies to Latin America during the 1970–80s, mention should be made of the 300 MW steam turbines that were installed at Bahia Blanca and Costanera, Argentina. As the last Soviet project for the facilities of today’s Power Machines, four hydrogenerators with a capacity of 390 MVA each were manufactured for the Piedra del Águila HPP in Patagonia, Argentina. The early 1990s, which coincided with the painful severance of all established economic ties, as well as a decline in production for machine building companies in the former USSR, were also challenging for Latin American countries. It was in these years that the region began to comprehend the new realities of its development and initiated the complex process of developing its main vectors. As major oil and gas fields were discovered in the region, this enhanced opportunities for power supply by adding thermal energy resources to the traditional water resources. In the meantime, integration processes were reinforced and expanded, and the intercomplimentary nature of various countries in the sphere of power supply became recognized at a government level, as were possibilities for cooperation. This process contributed to the economic integration of the region’s countries, which eventually resulted in the establishment of the Southern Common Market, MERCOSUR, which is the Latin American version of the EEC. A number of energy crises that broke out in Brazil, Argentina, and Chile in the early 2000s accelerated the making of decisions aimed at developing the power industry across the region. Interconnected fuel and energy development programs which provided for the improvement of existing and construction of many new power facilities were created with the participation of MERCOSUR. Fortunately, the facilities which are now part of Power Machines managed, through truly heroic efforts, to remain among those few post-Soviet power engineering companies that continued to supply equipment abroad, including to Latin America, during the 1990s. It is worth mentioning that, while carrying out their supply missions, they successfully entered new markets. Two notable projects, the Aguamilpa and Huites HPPs, were implemented in Mexico. And four hydropower units, equipped with LMZ turbines and Electrosila generators, were supplied to Urrá I HPP, Colombia. While implementing these projects in Colombia and Mexico, the company also opened new foreign offices which exist to this day. Meeting at a new stage The Russian company resolutely reasserted its market presence in Latin America in the mid-2000s, and that despite the increasingly competitive environment, both among the world’s largest manufacturers, which paid considerable attention to the region, and with local power engineering companies. However, Power Machines successfully overcame all difficulties and convincingly won a number of major tenders. In 2002–2004, a project was implemented whereby equipment was supplied to the Porto Góes HPP in Brazil. A turn-key contract was also executed in April 2003 for El Cajón HPP, Mexico, which was designed as a new plant within the existing hydropower system on the Rio Grande de Santiago. With this, the RussianMexican cooperation that had started with the Aguamilpa HPP continued. Power Machines’ contractual obligations under the El Cajón project included the supply of all electromechanical and auxiliary equipment for the plant’s two 375 MW power units. In 2005 Power Machines added Chile to the countries where it has a presence; there Traditionally, Latin America includes Brazil, a country where Portuguese is spoken, and the Spanish-speaking countries of the American continent from Mexico in the north to Argentina in the south along with the Spanish-speaking Caribbean countries: Cuba, the Dominican Republic, and Puerto Rico 16 BRANCH OFFICES Latin America May–September 2014 | International (special) issue 1 (3) MEGAWATT 17 3 4 1 1 contract, this one to supply hydroturbines and hydrogenerators for two power units with a capacity of 77.5 MW each to La Higuera HPP. The Chilean office, opened in 2005, becoming the fourth in Latin America. Brazil — one of the two countries that had been pioneers in Russian-Latin American cooperation — remained the only country in the region where the company did not have its own “base.” This gap in the company’s geographic coverage was successfully bridged by Power Machines in mid-2009 when the decision was made to establish a branch in San Paolo, Brazil. To stay on top 2 the group won a tender to supply equipment with a design capacity of 73 MW to Quilleco HPP. Power Machines became the first power engineering company from Russia to implement a project in this Latin American country. The tender competitors included Brazilian divisions of Voith Hydro (Germany), Alstom (France), and General Electric (USA). Chilean power engineers, however, preferred the Russian group because of its advantages, which were its flexible pricing policy, many years of successful operation in countries of the region, and the use of new technical solutions, particularly Teflon hydro generator bearings. Something else of importance was that Power Machines undertook to meet a very tight contract schedule with equipment to be supplied for the first power unit of the HPP as early as June 2006 and for the second power unit in August 2006. Nonetheless, the company was successful in meeting such a tight schedule. It demonstrated integration and accuracy despite the fact that the Chilean market was new to the company. The power plant was launched in June 2007. Three years later, the Quilleco HPP and the Russian equipment it uses fully proved their reliability during an earthquake in Concepcion: after a 30-second routine shutdown that lasted as long as the shocks continued, the plant automatically restarted and returned to its normal operational regime. This unscheduled “seismic resistance test”, brilliantly aced by Power Machines, was acknowledged by power companies across the region, where seismic activity is a major challenge of routine operations. Prior to the completion of the Quilleco HPP, Power Machines signed a second Chilean “The logic we have behind opening new offices in various countries is simple,” Alexandr Maslennikov, Head of Regional Sales — Latin America, explains. “Each one was established when needed for a particular project and became a kind of outpost for the company in the region, providing in-situ follow-up on existing contracts while at the same time identifying opportunities for further representation in a given country. Traditionally, every office has its “associated countries’ — neighboring countries with potential cooperation opportunities. Thus, Alexey Petrov, the head of the oldest office in Argentina, is also in charge of Uruguay, Paraguay and Bolivia, whereas Oleg Yefimov, who works in Chile, and Artyom Varnakov, the head of the Brazilian office, are responsible for Peru operations.” Following this logic, the opening of the Brazilian office was timed to coincide with a new contract to supply equipment to São João HPP executed in 2008. Urra-1 HPP 2 Transportation of the stator for the Punto Negra HPP 3 Alexander Maslennikov, Head of Regional Sales, Latin America 4 5 La Yesca HPP, Mexico 5 “In conditions where in Latin America, as in the rest of the world, the main form of supply remains comprehensive and contracts re “turnkey”, Power Machines can fully demonstrate a competitive advantage in its broad product range,” says Alexander Maslennikov “The key challenge in accessing a new market is not to open a representative office as such but rather for it to keep its pace up after the first major project. If you give away the momentum, if you lose steam, all previously made efforts may “vanish into thin air.” It is almost impossible to return to a market you have been forced out of,” Alexandr Maslennikov says. “We therefore try to cover several areas, working through new construction projects while at the same time renovating existing plants; and we make contracts and agreements for spare parts.” The many years of cooperation between Power Machines and the Colombian power industry can genuinely be regarded as very successful. Having equipped the Urrá I HPP, the company proceeded as its operator in the late 1990s by entering into an appropriate contract which was later prolonged on more than one occasion and is in effect to this day. Hence, formally, the Colombian office may be deemed the largest of the company’s Latin American offices. Here, at EMEKEMEC S.A.S., Power Machines’ subsidiary, six Russian engineers work side by side with about one hundred Colombians, who became “Russian workers’ thanks to Urrá I HPP. The high quality of the equipment, its effective exploitation and a series of other factors provided by Power Machines and the Russian engineers at EMEKEMEC S.A.S. allow the power station to be operated stably and safely. This is confirmed by the continually high coefficients for the station’s readiness and the customer’s intention to continue working with Power Machines and EMEKEMEC S.A.S. In addition, we can note that the Urrá I HPP is also unique in that it is the only hydro-electric power station in Colombia that is operated by the company that manufactured its basic equipment. Among the major service contracts recently made by Power Machines in Latin America, it is worth mentioning the contract for hydrogenerator diagnosis and thermal and ventilation testing as well as the technical and functional assessment of hydroturbines at the binational Salto Grande HPP. Today the plant is being prepared for large-scale renovation. Argentina’s Piedra del Águila HPP, where four hydrogenerators from Electrosila have been in operation since the late 1980s, has been renovated, and not without the participation of Power Machines. The company supplied spare parts kits here twice — in 2007–2008 and 2012. In 2011–2013, spare parts kits were manufactured and supplied to the São João and Porto Góes HPPs of Brazil under additional agreements. A package of service and spare parts contracts for Chilean HPPs, Quilleco and La Higuera, was also significant. New prospects “Based on its performance over the past decade, Power Machines feels quite confident on the Latin American market,” Alexandr Maslennikov says. “The company has over two dozen major contracts under its belt, including taking into account its Soviet experience.” 18 BRANCH OFFICES Latin America May–September 2014 | International (special) issue 1 (3) La Igera HPP, Chile The first hydropower unit at São João HPP in Brazil was launched in the spring of 2012, and the second was launched in July of the same year. In 2013, two hydropower units with a capacity of 375 MW were put into service at the La Yesca HPP in Mexico, which became part of the hydropower system on the Rio Grande de Santiago. As distinguished from previous contracts performed on the same system (Aguamilpa and El Cajón), in the case of La Yesca, Power Machines not only supplied two hydrogenerators and auxiliaries but also designed and installed electromechanical equipment for the turbine hall on a turn-key basis. The warranty period is now about to expire and, according to Sergey Suprun, the head of the Mexican office, it has been quite successful. The Argentinean supply contract signed between Punta Negra HPP and Power Machines in 2011 is also coming to a close. All the equipment has been manufactured and by now almost completely delivered to the plant. It is planned that in the autumn there will a significant rise in the volume and intensity of the assembly works, which will allow the station’s hydro-equipment to be launched on time. The launch of the Punta Negra HPP is planned for the end of 2015. This station will be the seventh power plant in Argentina using equipment, manufactured by Power Machines. It should The region’s power industry is mainly composed of hydropower plants (approx. 52%) and thermal power plants (approx. 45%). HPPs account for about 90% of Brazil’s total electricity generation and about 75% of Chile’s be noted that the projects on the San Juan river, the Los Caracoles HPP and the Punta Negra HPP, are the only new hydro-electric power stations in Argentina for the last 15 years, and it’s of particular significance that hydro-electric power equipment supplied by Power Machines is being used for both projects. This is evidence of the high level of trust of the Argentinian customers in the quality of our equipment and the professionalism of our specialists. “Now that EPC and turnkey contracts are becoming increasingly popular in Latin America, as well as everywhere else in the world, Power Machines can fully demonstrate the competitive advantage of a wide product range,” says Alexandr Maslennikov. “Today we can supply our clients not only with turbines and generators but also with transformers and boilers manufactured by our company. I believe we have every reason to stake a presence in those countries where Power Machines have not operated yet, such as in Ecuador, where Inter RAO UES is already extending its domain. As a crucial step toward its consolidation in the Latin American market, the company will set up its own production facility in Santa Catarina, Brazil; its purpose will be to supply equipment to the markets of Brazil and other MERCOSUR countries. This will enable the company to meet all of the tender procedure requirements imposed by Brazilian laws as well as to reduce delivery expenses and exclude import taxes from equipment prices. “Latin America is among the regions of particular interest to our company,” Alexandr Maslennikov says. The veracity of these words is supported by figures which illustrate the situation relating to the power market in the region. Today, nearly all Latin American countries have governmentally approved power industry development programs. Brazil, for MEGAWATT 19 example, intends to launch about 70 GW of new capacities by 2021 as well as to renew up to 40% of existing HPPs. About 8 GW of new capacities are planned for introduction by 2020 in Chile, and another 4.7 GW in Colombia by 2022. In the development of their power industries, both of these countries have traditionally backed smaller scale HPPs; and Power Machines have good prospects in both of them. As part of the energy diversification that has been happening in Latin America over the last 20 years, the nuclear power industry is also developing gradually. Argentina is currently busy with developing nuclear construction plans. Importantly, this is one of only three countries in Latin America already having an existing NPP within its power system and also having its own facilities for the processing of uranium, advanced manufacturing techniques with which to obtain radioactive materials, and considerable experience in designing lowpower reactors. The share of nuclear power is only slightly over 2% in Latin America as a whole, but it is approaching 7% in Argentina and, with the depletion of explored oil and gas reserves in the country, is likely to grow. It is therefore quite possible that Power Machines’ experience in manufacturing equipment for NPP applications will be in demand by Latin American countries in the immediate future. “Competition in the Latin American market is intensifying these days,” says Alexandr Maslennikov. “However, many power companies across the region have already come to appreciate the significant benefits of working with Power Machines, such as high equipment reliability, the good power margin of the power units supplied, the comparatively low cost of production and engineering services, and the best possible methods of communication with local personnel. The qualifications of our managers are another essential advantage. All our local employees are professionals with solid working experience. They know our product range perfectly and are ready to expertly discuss all the details of the future contract with clients.” Representatives of Energia Elaima (Chile)visit the Russian enterprise. June, 2014 Tubrine shaft, La Igera HPP, Chile Antonina Krischenko Comment Having operated equipment manufactured by Power Machines for many years, I can single out such features as efficiency, reliability, the high quality of materials, convenient installation, an ergonomic maintenance design, and the ease and efficiency of adjustment. The combination of these parameters makes the Russian group’s products reliable, user-friendly, and durable. Marco Antonio Tisnado Brito, General Director of La Yesca HPP 20 BRANCH OFFICES May–September 2014 | International (special) issue 1 (3) Latin America Power Machines in Latin America Chile — What are the unique advantages of the Chilean power market? — The transparency of the market mechanisms influencing contract awards is an important advantage. The vast majority of Chilean energy providers give preference to solid references and proven brands. Price, quality, efficiency, and maintainability are all evaluated based on comprehensible and real performance indicators, and only as an entirety. As Power Machines is able to offer the best possible combination of the aforementioned parameters to their clients, it is always in the focus of Chilean power companies. Oleg Yefimov, Director of the Chilean Office Argentina — How is it going with the Punta Negra project? — The contractual supply of equipment for Punta Negra is nearing completion. All the necessary equipment has now been manufactured and delivered to the continent. It will have arrived at the plant by the end of the summer and installation will begin in the autumn. Punta Negra HPP will begin operation in late 2015. Alexey Petrov, Director of the Argentinean Office Brazil — How will the company by setting up its own power equipment production contribute to successful cooperation with the country? — Brazil has a concessionary financing program for new and renovated power facilities which has been in effect for five years. However, only facilities that use equipment from national manufacturers can join the program. So Power Machines will need to obtain the status of a national manufacturer to successfully operate on the Brazilian market. Our company is currently assessing a Brazilian facility for possible acquisition. The facility is expected to manufacture hydrotur- bines and hydrogenerator components. I should add that Power Machines are adequately experienced in successfully working with some Brazilian research and production companies, and the localization of production will augment this experience both in Brazil and in other Latin American countries. Artyom Varnakov, Director of the Brazilian Office Colombia — How will customers benefit from involving equipment manufacturers in plant operation? — Customers benefit for a number of reasons. First, manufacturing company personnel have a great deal of experience obtained from operating previously built facilities. Second, the permanent presence of a manufacturer’s representatives makes it possible to address as fast as possible any issues arising in the working process and related to operating conditions or the improvement and renovation of equipment. Finally, such a pattern of cooperation facilitates the prompt supply of any original spare parts that may be necessary for routine, scheduled, and unscheduled repairs, as well as overhauls. Manufacturers also benefit from such cooperation. Indeed, this is the sort of “feedback” that helps them keep track of possible problems with designed and manufactured equipment and which enables them to collect very valuable inforChilean Energy Minister Jorge Bunster at the Power Machines stand, Expo Apemec Exhibition, June 2014 mation to help them work out innovative design solutions, timely suggestions as to equipment improvement, and preventive measures that ensure trouble-free operation. Therefore, such cooperation is a mutually beneficial process, and its importance for both parties would be difficult to overestimate.

MEGAWATT Next La Yesca HPP Huites CARIBBEAN SEA Aguamilpa La Yesca El Cajon Urra-I MEXICO Maximo Gomez Antonio Maceo COLOMBIA CUBA Este Havana Mexico — How do you estimate the results of the warranty period at La Yesca HPP? — Work during a warranty period is always rather difficult as it is carried out while an HPP is in operation. Nevertheless, none of the customer’s concerns have been ignored. A positive completion of the project is the final touch and has an appreciable effect on a company’s reputation; so Power Machines pay no less attention to this stage of work than to equipment manufacturing and installation. I should emphasize that no major problem or equipment defect has been detected during the warranty operation period — which at La Yesca HPP is 24 months from the date of temporary acceptance and will expire this November — and we, as Power Machines’ representatives, have never had to be embarrassed about our equipment.

The main power generating equipment for the plant was supplied and installed by Power Machines. Notwithstanding the fact that both hydropower units, commissioned in October and November 2012, have since then been in normal, failure-free operation, for Power Machines the project is still not completed. The company’s warranty will only expire in 2014, two years after the commissioning of the units. Within the scope of La Yesca HPP project, Power Machines has worked as a subcontractor for CPH, a Mexican construction services company and a subsidiary of ICA which won the competitive bidding organized in 2007 by the Mexican Federal Electricity Commission. It is no coincidence that the power machine building company based in St. Petersburg joined this project. Power Machines had already proven itself to be a reliable partner: it supplied equipment for two other power plants for the same HPP system – Aguamilpa (975 MW) and El Cajon (750 MW). According to the contract, the scope of supply that Power Machines was responsible for included two 375 MW radial/axial hydro turbines with impellers, a diameter of 5.3 meters and built-in ring seal gates, two hydro generators, equipment for a gas-insulated substation, as well as hydromechanical and electrical facilities, and mechanical support equipment. Additionally, the company provided a traditional set of turn-key services: installation and commissioning, including a comprehensive range of acceptance and warranty tests and putting the units into operation. Notwithstanding the “traditional” character of contractual obligations, the project had La Yesca is the third Mexican HPP fitted out with equipment by Power Machines 24 Partners May–September 2014 | International (special) issue 1 (3) La Yesca HPP MEGAWATT the hydroturbine was tested using the thermodynamic method, which is currently considered the most innovative and promising of its kind. Additionally, in February 2014 a range of hydrogenerator tests were run. The equipment successfully passed voltage recovery and load dropping checks, as well as high-voltage tests to examine stator and rotor winding for faults using alternating voltage. In accordance with their contractual obligations, Power Machines will continue addressing minor issues in the course of normal equipment operation and submit the complete set of project documentation, La Yesca HPP earned the title of “Construction Project of the Year” issued upon completion of all works, to the customer. The La Yesca HPP project is of key importance for the Mexican hydropower sector. In 2008, Felipe Calderón, who was the country’s President at the time, emphasized this point in his speech marking the official start of construction. In 2013, the plant’s status was acknowledged by Obras (Construction Projects), a highly-respected Mexican trade journal, which named La Yesca HPP the “Construction Project of the Year” as a hydropower sector project of several specific requirements. In particular, the customer insisted that the equipment should be manufactured by a number of companies across Mexico and other countries. “In accordance with our contractual obligations, we supplied the complete set of electrical and mechanical equipment and auxiliary process control systems manufactured by various companies,” says Igor Uskov, Chief Project Engineer, Hydropower Department of the Engineering Support Unit at Power Machines. “Another peculiarity was related to the government support policy typical for many Latin American countries. It was important for the customer that 25% of equipment costs accrued to local companies’ manufacturing facilities.” This made the company’s contractual obligations much “heavier” in terms of organization and logistics, since it had to enter into a great number of subcontracting agreements with Mexican entities, as well as international companies that have branches in Mexico. A long process of negotiation led to the working out of a list of equipment to be manufactured in Mexico. Thus, an important feature of this project was the necessity to coordinate engineering work done by various suppliers, to monitor if units of several hundred types were compatible, and to control the interfaces with the construction process. This extremely challenging and meticulous task was professionally handled by Power Machines de Mexico S. A., Hydroproject de Mexico (the project's general designer) and the Engineering Support Unit at Power Machines. 5.3 m – the diameter of an impeller for a radial/axial hydroturbine The manufacturing and supply of the main equipment was completed in 2010, and in autumn 2012, Power Machines put into operation two hydropower units (the first one was commissioned in October and the second one in November). This put the plant’s total rated capacity at 750 MW. “The equipment has worked failurefree since being put into operation, and its operability can be regarded as satisfactory,” says Anna Loginova, Project Manager of the Department of Project Execution of the Sales Directorate (External Market) at Power Machines. “Over the past year, we have identified and fixed minor faults, and continued aligning and adjusting process control systems, which is normal practice for complex equipment during the warranty period.” In the autumn of 2013, the plant underwent comprehensive warranty testing which confirmed the rated efficiency of the hydrogenerator and turbine, as well as full compliance of the equipment with contractual requirements. This international project also involved testing performed by specialists from a number of companies. For instance, the hydrogenerator was tested by LAPEM (Mexico) professionals, supervised by Electrosila employees who had developed the testing procedure; while the turbine equipment was inspected by Sweco, an engineering company based in Norway, assisted by manufacturing facility and Power Machines' Engineering Support Unit representatives. It is worth noting that for the first time in the history of the Russian power machine building company, Next Sayano-Shushenskaya HPP Dam Height 245 220 168 128 SayanoShushenskaya HPP La Yesca HPP 96 Charvakskaya Krasnoyarskaya Boguchanskaya HPP HPP HPP highest priority in the social sphere. This title is well-deserved. La Yesca HPP is a unique hydrotechnical facility featuring one of the highest earth-fill dams with a reinforced concrete screen and a number of underground structures in the world (the dam is 220 m high). Such a complex project could only be completed following the strictest requirements regarding deadlines and equipment quality. Today, the project can undoubtedly be deemed a success. For Power Machines, La Yesca HPP is another pin on the map of Latin America, alongside other hydropower stations such as Aguamilpa, Huites and El Cajon, which were also provided with the company's equipment. The project strengthened the company’s reputation as a reliable and highly qualified subcontractor, which is very important, considering the expected international bidding to be organized by the Mexican partners for such projects in the hydropower sector as Las Cruces, Nayarit State, and La Parota, Guerrero State. Ivan Denisenko Comment Marco Antonio Tisnado Brito, General Director of La Yesca HPP La Yesca HPP plays a key role in the Mexican utility system. It’s the country’s largest power plant equipped with the most innovative technology. We had been discussing the need for its construction for several years, and when all agreements and contracts were finally signed we were genuinely anxious to see it built, equipped and commissioned. It was a very complex but nonetheless interesting project. Power Machines, which worked as a subcontractor for the project, has once again proved its status as a reliable partner. The Russian company manufactured, delivered, installed and tested the main power equipment for the turbine building. I would like to express my special gratitude to the Power Machines’ engineers. They are highly skilled professionals, and it is remarkably easy to reach common ground with them. For the energy that powers our country today we should thank, among other stakeholders, the company from distant St. Petersburg. And I am delighted to note that our specialists who carried out the acceptance of the equipment locally have been fascinated by the beauty and splendor of the Russian city. 25 26 projects ??? Sayano-Shushenskaya HPP May–September 2014 | International (special) issue 1 (3) MEGAWATT 27 A major accident occurred on August 17, 2009, as the cover of hydropower unit No. 2 had been removed by water flow, due to broken fasteners. As a result, all of the hydropower units available at the largest (6.4 GW) HPP of Russia were stopped. Some equipment was destroyed. Design alterations Sayano-Shushenskaya HPP: new hydropower units for the power grid of Russia The restoration project at Sayano-Shushenskaya HPP, in the Republic of Khakassia, is scheduled to be completed in 2014. The plant will be completely fitted with new and advanced high-performance equipment. New hydropower units have been supplied by Power Machines. The contract to manufacture and supply power equipment required for the restoration and renovation of Sayano-Shushenskaya HPP (SSHPP) was signed by Power Machines and RusHydro in November 2009. The group was to manufacture 10 hydroturbines and 9 hydrogenerators with a capacity of 640 MW each as well as six excitation systems. New equipment was built at Power Machines' facilities within the shortest time period and supplied to the plant from November 2010 to January 2013. The equipment for SSHPP was specifically developed by Power Machines for this task. The group engineers developed an improved impeller configuration so as to reduce water flow effects. The hydroturbine was designed with guide vanes actuated by a single actuator with a shift ring, eliminating the uneven rotation of vanes and maximizing design reliability. The turbine impeller and guide vanes were manufactured using a new stainless steel. As a result, the alterations in the design improved the rigidity of the turbine cover by 50 percent. The new SSHPP generators have a diameter of 17.5 m and a weight of 1847 tons. The new units used low specific loss electrical steel, which ensured reliability, improved efficiency and enhanced the service life of the generators. Fault detection and emergency water shutoff systems have also been improved with each hydropower unit now fitted with several hundreds sensors including shaft shaking, air gap, pin force, pressure fluctuation and cover vibration displacement sensors. All information from the sensors is processed by an automated control system, transmitted to an operator station and ar- The contract to manufacture and supply power equipment required for the restoration and renovation of sayanoshushenskaya HPP was signed by Power machines and Rushydro in November, 2009 28 projects May–September 2014 | International (special) issue 1 (3) Sayano-Shushenskaya HPP MEGAWATT cy protection. Some of the protections, previously used in algorithms as preventive, have become emergency protections, providing a tripping action. As a consequence, there are physically more protection checks to be done during individual and comprehensive testing of systems and the unit as a whole. But the testing programs have fundamentally remained unchanged,” he says. Certain difficulties arising in the course of testing are dealt with along the way, there are no special comments to be made, and it’s a normal working process, the regional director adds. Once renewed, hydropower unit No.4 was subjected to necessary testing and put into commercial operation in late April, 2014. Today the operating capacity of SSHPP is 4480 MW with hydropower units No.1, 4, 5, 6, 7, 8, 9 and No.10 being in service. New equipment is still being installed in hydropower units No. 3 and No.2. These are expected to be put into operation in June and September of 2014. New objectives “After introducing hydropower units into commercial operation, the company has new objectives in addition to the aforementioned installation work such as maintenance service of the units during the warranty period, which is for 36 months following their introduction. In continuation of their cooperation under the SSHHP Unloading of the latest working wheel for the Sayano-Shushenskaya HPP chived. Besides monitoring and control, the system developed by Power Machines provides water shutoff and unit shutdown in case of abnormal working parameters. Hydropower unit No.6 was the first unit hooked up after the accident. It was launched on February 24, 2010. The next, hydropower unit No.5 was put back into service on March 22, 2010, and hydropower unit No.4 on August 2, 2010. They were followed by hydropower unit No.3, which was hooked up for performance testing in December 2010. Its startup ended the first restoration stage which included the startup of four hydropower units, the least damaged by the accident, following their overhauling. In spite of difficult conditions According to Sergey Ivakin, Director of Power Machines’ Office in the Republic of Khakassia, a working group was formed of leading technical specialists, engineers and developers of Power Machines at the SSHPP site in September 2009 in order to complete the restoration of the hydropower units and to follow the instructions of the group's management. The group’s prime objective was to promptly develop an plan of action related to fault detection, repair and recommissioning of the generating hydroequipment, damaged by the accident. “Structures and components of the damaged hydrogenerators and hydroturbines as well as control systems had to be fully inspected in extremely challenging emergency conditions, in the ruined machine building and at near zero temperatures. Equipment restoration and repair work was commenced with people from RusHydro”, Sergey Ivakin says. “Once the repair had been completed, specialists from Power Machines and SSHPP’s technical personnel proceeded to commissioning and comprehensive testing and then put the hydropower units into operation.” The first series of four SSHHP hydropower units was put into service within less than one and a half years of the accident, reducing the power shortage in the Siberian Federal District, avoiding sterile spills in the winter period and improving structural safety. In 2011 the second stage of plant restoration began to be implemented. While restoring and installing hydropower units, Power Machines fully inspected turbine wheelspace and penstock, installed stabilizing fins in a suction tube, installed and adjusted main and auxiliary equipment, and automated control and protection, ex- Next Beloyarskaya NPS At work - an auxiliary stator for Sayano-Shushenskaya HPP project, Power Machines and RusHydro signed a contract to provide technical maintenance and repair management for hydropopwer units covered by warranty. I am convinced that such cooperation will be positive for both the parties and will be continued when the warranty expires,” Sergey Ivakin says. As a result of the renovation, the life of the new hydropower units at SSHPP, manufactured by Power Machines, increased to 40 years and their estimated efficiency is now 98.41% (previously it was 98.3%). Vladimir Nikolayev Background citation, vibration and thermal control systems. In the course of the work, focus was made on the quality of basic process operations. In 2012, three new hydropower units, No.7, No.8 and No.9, were put into commercial operation, increasing the plant’s capacity to 3840 MW. Also in 2012, hydropower units No.6 and No.5, launched into service after an overhaul in 2010, were taken out of service for the replacement of ke components (turbine, generator and auxiliary equipment). Three new hydropower units, No.10, No.6 and No.5, were put into commercial operation in 2013. Furthermore, hydropower units No.4 and No.3, which had been restored earlier, were shut down for removal and complete replacement. Toughening requirements The testing of the new hydropower units and those restored in 2010 is very different in the scope of work required, Sergey Ivakin explains. “Following the accident in August 2009, supervisory bodies have significantly toughened operational safety requirements related to hydropower units. As a result, there are more hydropower unit parameters to be monitored and also more sensors to be engaged in emergen- Sayano-Shushensky Hydropower System stands on the Yenisei River, in the Sayansky Canyon, where the river enters Minusinsk Hollow. The system includes Sayano-Shushenskaya HPP, Maynsky reregulating reservoir hydrosystem located downstream, and the shore spillway. Power Machines is currently fulfilling a number of orders under contracts for other Russian HPPs in compliance with RusHydro’s comprehensive renovation program for the period of 2012 to 2020 and probably to 2025, aimed at improving the operational reliability of power plants and replacing obsolete equipment. The program is intended to replace 55% of turbines, 42% of generators and 61% of transformers from RusHydro's fleet. 29 30 projects Beloyarskaya NPS May–September 2014 | International (special) issue 1 (3) “There is a lot of interesting work to be done together!” MEGAWATT 31 From a project to a contract Designers of Leningradsky Metallichesky Zavod (LMZ), now included in the Power Machines structure, began designing a turbine for the largest domestic nuclear power plant as early as the late 1970s. The development work originally intended for Beloyarskaya NPP was subsequently readdressed for Yuzhnouralskaya NPP and frozen for a long time after the Chernobyl tragedy as were many other projects in the nuclear industry. The design and engineering work was resumed in the early 2000s. The engineering design was significantly revised, taking into account the experience obtained by the LMZ designers in the field of high-power turbine designing for TPP and NPP and new requirements that address reliability and operational safety improvement for nuclear power plant equipment. In the summer of 2007, Power Machines and JSC Engineering Company ZIOMAR signed a contract for the supply of powergenerating equipment for the 4th unit of Beloyarskaya NPP with a БН-800 reactor, which is currently under construction. Under the terms of the contract, Power Machines has carried out the design and engineering work, and manufactured and supplied a К-800–130/3000 type steam turbine and condenser, certain auxiliary heat-exchange components for the turbine set, as well as a 890 MW Т 3В-890–2УЗ turbine-generator set. Moreover, the service package, in keeping with tradition, included the supervised installation and commissioning management services. Small high-output turbine “The К-800–130/3000 is a prototype of a new steam turbine for an innovative project of a high-output power unit with a fast power reactor,” says Petr Prikhodko, Chief Project Engineer, Engineer of Steam Turbine Design Department, Special Design Bureau Turbina, LMZ. “The turbine has several structural features, such as a unique cylinder combining high and intermediate pressure flow sections.” Photo evidence This year at Beloyarskaya NPP marks the 50th anniversary of its commissioning – it was half a century in April since the launch of the first unit. This power plant and Power Machines manufacturing facilities have a history of long-term cooperation, as well as large-scale plans for new joint projects. A tube plate manufacturing process for the K-800 turbine that involves an explosive titanium cladding technique is of particular interest. This procedure was performed at a test site near Sverdlovsk. Explosive material was evenly distributed over the plate surface, and then a detonator was activated remotely. As a result of the explosion directed from the centre to the edges of the plate a 5-mm titanium sheet was uniformly welded to the basic plate made of carbon steel. 32 projects May–September 2014 | International (special) issue 1 (3) Beloyarskaya NPS MEGAWATT Next Test facilities it possible to extend the unit's service life. Currently, we are facing the task of extending the life cycle of the third power unit for another 15 to 20 years. “We have developed several modernization alternatives for high pressure and intermediate pressure sections with increase in output,” says Igor Zaitsev, Head of NPP Service, Modernization and Spare Part Supply Division, Nuclear Power Directorate. “In addition, we suggest the replacement of the hydrogen- and water-cooled generator with an air-cooled one, and the existing control system with a more state-of-theart version.” Negotiations regarding the project are in progress, the parties are trying together to strike the right balance which will make it possible for the machine manufacturers to apply more effective solutions and for the generating company to optimize the investment budget and calculate the costs and payback period. An additional fourth power unit will be “put on the books” of the Power Machines service divisions after K-800 turbine commissioning. A fifth power unit project with fast power reactors would be the obvious continuation for the effective cooperation between Power Machines and Beloyarskaya NPP. Its construction is of strategic importance for the Russian power industry and is one of the high priority mid-term plans of Rosatom Corporation. Machine room of the energy block with a БН-600 reactor, Beloyarskaya NPS Ivan Denisenko According to Prikhodko, the unique high pressure cylinder housing is made of high-temperature steel used for superheated steam turbines together with stainless steel that provides reliable wet steam application. The housing parts are welded with a composite seam. Increased turbine inlet steam conditions as compared with those of VVER power units made it possible to obtain a high-performance turbine set. Power output under the rated operating conditions is 885 MW. An attempt to combine high pressure and intermediate pressure sections within a single housing was successful as the steam is reheated in the separator reheater upstream of the low pressure cylinders, rather than in the steam generator as in TPP turbines. Thus, the turbine length and weight were reduced. “This is of the utmost importance, especially considering the high cost of the turbine building construction, as well as its dimensions,” explains Aleksandr Sergeev, Project Manager, NPP Sales and Project Management Department, Nuclear Power Directorate, Power Machines. “The work space at the 4th Beloyarskaya NPP unit is fairly compact, due to decreased dimensions of the turbine (as compared with, for example, the Leningradskaya and Novovoronezhskaya 1000 MW units). Actually, several solutions suggested by the Special Design Bureau Turbina designers were implemented in the turbine building design. And prompt release of the detailed design documents for process piping of certain turbine plant systems made it possible to start the assembly work ahead of the specified dates.” The heat exchange components also have some key features – among innovative solutions are condensers, where titanium is used as a basic material for internal components, notably the tubes and tube plate. The titanium condenser is distinguished by improved efficiency and reliability – it’s no coincidence that this solution by Power Machines has attracted the attention of many Russian and foreign plants, for which modernization is essential. Unit by unit Currently, large-scale works for the installation of the delivered components have been started at 4th unit of Beloyarskaya NPP. The successfully performed critical and time-consuming job of installing the Т 3В-890–2А-У3 turbinegenerator set on the foundations was a key milestone. It should be noted that among the benefits of a generator produced by Power Machines are greater fire safety and increased reliability. Heaters have now been installed in their locations, and bearing housing installation and the first and third low pressure cylinder assembly works are in progress. The work is being carried out by the contractor's personnel under the supervision of Power Machines engineering supervisors. It is planned that the commissioning activities, scheduled to last two months, will begin in the summer. The third power unit, its “arsenal” consisting of three 210 MW К-200–130 turbines, is an additional “intersection point” of the power-plant engineering company and the nuclear power plant. It should be noted that it is the world’s only acting power unit with a БН-600 industrial-level output fast power reactor. In accordance with the contracts in force, Power Machines control the turbine equipment manufactured by LMZ in the 1980s: scheduled maintenance, support servicing and spare part supplies are carried out on a regular basis. Low pressure assemblies were retrofitted in 2009 with shaft stages replaced with advanced blades that made Comment Mikhail Pimenov, Head of Turbine Shop-2, Beloyarskaya NPP Our companies have a long-term history of partnership relations, and that is not surprising: Beloyarskaya NPP represents the strategic direction of the Russian nuclear power industry growth, and Power Machines is reasonably regarded as a leader in domestic power-plant engineering. Your company declares a customer-oriented approach as one the basic operational principles, and this is not mere words. The Power Machines engineering personnel are always eager to assist in solving various issues, arrange on-site examination, if necessary, and provide the required advisory services. The specifications of your equipment also deserve the highest praise. As the plant representative, I would like to note that the Power Machines equipment is not only reliable, it’s also very user-friendly, and this is very important. We have a shared experience of successful cooperation at the third power unit, which is currently in operation, and the fourth power unit, which is in the course of its start-up process, of Beloyarskaya NPP. Dear colleagues, I’m sure that we have a lot of interesting work to be done together! 33 34 Innovations Test facilities May–September 2014 | International (special) issue 1 (3) MEGAWATT operate the turbine during testing, checking parameters on their displays. Commissioning is a long and sequential process – at first each of numerous systems is tested independently, and then in combination with other systems. New systems are tested and introduced step by step. “As well as people from our company there are also contractors working at the facility: automation specialists, fitters, en- new testinG range for steam turbines Large-scale work on renovating Power Machines' steam turbine field test facility is coming to a close at TPP-17, St. Petersburg. The unique range will provide our company with totally new opportunities to try out innovative design solutions. In April a pilot steam turbine reached a no-load condition at a rated speed. The noise from installation works was loud at the spacious facility premises until recently. Today, there is quite a different range of sounds - those generated by start-up operations: steam hissing, pipework sounds, the roar of hundreds of devices that are being setting in motion. New performance The renovation project is intended to achieve new power capacities. “There are no other facilities like this in the world,” says Alexandr Nekrasov, Head of Field Test Research at LMZ’s Turbina Special Design Bureau. “This facility has no match as far as such key indicators as steam flow and capacity are concerned. The test steam flow, for example, has increased from the previous value of 380 t/h to 600 t/h. In addition, technical design solutions, previously only used at nuclear plants , have been implemented to provide soft start-stop operation when working in combination with TPP-17 equipment. Large-scale renovation The project scope included renovation of steam supply and recirculating water and power supply circuits, and replacement of the high-pressure steam line and feedwater conditioning system. An extensive series of repairs has been done on pipework foundations and supports; a new automated facility control system was introduced (with about 90% of equipment automated). Furthermore, new steam turbine, turbogenerator and hydraulic brake control systems were installed along with a turboset mechanical monitoring system. Vibration control equipment was inspected. Midway The control room has been completely transformed. It is from here that engineers from Turbina Special Design Bureau will Next gineers, electricians, and builders,” Alexandr Nekrasov says. “We check the functioning of all systems together, and any comments are resolved as soon as possible. A test facility is huge and complicated, and it takes time to be completely prepared for start-up at full steam flow. I can say we are midway now. The introduction of the facility will enable designers of Power Machines to field Meeting the First Cosmonaut test last stage blades and compartments of existing and future turbines at TPPs and NPPs. In particular, new blades are expected to be tested in the nearest future, including superlong blades for high-speed and low-speed NPP turbines as well as for turbines with ultra-supercritical steam parameters. Ivan Denisenko Schenck to permit turbine and generator rotor testing A Schenck balancing and spin bench is being prepared for launch at the new manufacturing facility of Power Machines’ new plant. Commissioning operations are provided by the manufacturer's engineers and also involve specialists from Power Machines. The new equipment will add to test facilities available at Power Machines. The balancing and spin bench from Schenck RoTec GmbH, Germany, is designed for high-speed balancing and overspeed testing of welded rotors. It will be possible to spin huge multi-ton rotors, placed in a chamber, to a speed of 6,500 rotations per minute. A unique machine Static and dynamic balancing is an obligatory test. It is used to evaluate the reliability of a product, its balance and the compliance of its dynamic behavior with the specifications stated in the design documentation. The new bench is unique in that it will enable handling of rotors of both steam turbines and generators since it can provide two different media: vacuum and heat additives. Individual requirements This is the most expensive and probably the largest structure in the low-speed turbine hall. The roomy bench chamber can be seen from the hall but this is just the tip of the iceberg – on the opposite side there is a machine hall, providing for the work of the structure, an electrical room, and a control room where the machine is operated from. It is worth mentioning that this structure was custom-designed by the manufacturer based on Power Machines’ requirements. Ivan Denisenko 35 36 HISTORY Meeting the First Cosmonaut May–September 2014 | International (special) issue 1 (3) MEGAWATT Next Olga Kovaleva A Veteran Recalls Machine Builders’ Space Mission This year we celebrate the 52nd anniversary of man’s first voyage to space. This was a landmark day in the history of Leningradsky Metallichesky Zavod, which was directly involved in the preparations for the flight. Unbelievable as it may seem, after so many years since those momentous times, some of the people who have a clear memory of Yuri Gagarin’s visit to LMZ in August 1962 still work at the plant. On April 12, 1961, literally every single person in the country was filled with pride and joy. The issue of Turbostroitel dated April 15, 1961 mirrored the general upbeat mood. The newspaper was filled with extracts from enthusiastic letters written by LMZ employees – and many more letters probably remained unpublished because a lot of people wanted to express their feelings and the newspaper just didn’t have enough printed pages to put them in. Making History “Each of us would be happy to stand in the place of this heroic pilot. Our hearts were with him during the flight,” wrote A. Ishin, HydroTurbine Shop Foreman. “Listening to the radio messages about the flight, I was concerned for him as I would be concerned for the most important person in my life,” wrote A. Nikolayev, Head of Assembly Fitters Team at the Steam-Turbine Shop. “When I served as radioman, I was lucky to record signals transmitted by the first Soviet satellite. It was only a short time ago. And now the whole world listens to the news and finds out that a Soviet man is in space! No one expected this could happen so fast,” wrote G. Deyanov, Lath Operator at shop No. 1. One of the longest serving employees at Special Design Bureau Turbina is Igor Yablokov, a design engineer who joined the plant in August 1957. In September 1959, the young specialist was called up for military service and joined the Air Defense Forces. In April 1960, his reserve regiment was deployed from Zelenogorsk to Baikonur to guard the cosmodrome which only a year later became Under Korolev's Control the launch facility that gained fame around the world. “It was a time of great achievements,” Igor Vitalyevich reflects. “The most impressive and memorable of them were the launches of space rockets with our first astronauts – Yuri Gagarin, German Titov, Pavel Popovich and Andriyan Nikolayev – on board. We were so proud of our homeland then.” LMZ employees have a special attitude towards the Cosmonautics Day: the plant was engaged in the process of construction of the spacecraft for Yuri Gagarin, and we are proud to recall this fact in the light of the upcoming anniversary of man’s first voyage to space. At some point during construction, the launching pad was to be boosted into the air without using the engines, but an experiment could not be conducted at the launch site. As Boris Chertok, who worked closely with Sergey Korolev, later wrote in his book “Rockets and People”, the trickiest part was that at the point of deployment, the launching system and the spacecraft were elements of a single dynamic system. The rocket’s movement could not be analyzed without taking into account the behavior of the launching pad, and the dynamics of the pad’s working parts could only be analyzed together with the rocket position indicators. A solution to this challenge was found at Leningradsky Metallichesky Zavod. Here, the new building of Steam-Turbine shop No. 21 (known today as No. 201), where major caliber gun mounts for the Navy were, at the time, produced, had the required high-bay area, embedding depth and erecting cranes. According to Boris Chertok, in the autumn of 1956 the launching system was delivered to LMZ instead of the launch site. Here, it was assembled and tried out by a team of specialists, including the plant workers. The experiment also required another manufacturing facility to construct full-scale mock-ups of all the assemblies made at LMZ. In Leningrad, the rocket met its launching system for the first time. Once all preparatory work was complete, a test “launch” was held – the spacecraft was lifted not with its engines, but with a crane. The process of testing the rocket and the launching system continued day and night. Over several hundred faults in the project and design, as well as errors in operational documentation, were identified and corrected. Sergey Korolev himself visited the plant to monitor the process. “Hundreds of design engineers, constructors, project engineers and military men were bustling about sawing, welding, reassembling all sorts of rocket parts; they were writing stuff down, discussing and debating about various issues,” Boris Chertok recalls. “In the area of shop No. 33 where heat treatment of impellers takes place, metal structures of Gagarin’s spacecraft were assembled and welded,” says Vladimir Brainin, Lead Engineer at the Principal Welder Department of LMZ, and the plant’s employee since 1959. “A special platform was constructed for production of assemblies for the rocket; there were spot wielding machines and a huge pavilion tent. You could only enter the tent if you had a special pass, which a sentry always checked.” A worker's view Yuri Gagarin probably forgot about this element of our plant’s “space” mission: when he visited LMZ in August 1962, he said to the workers, “No parts for our spacecrafts are produced here, but you do contribute to the conquest of outer space. Your turbines generate power which is needed to smelt metal for our satellite rockets.” Early in the evening, the entire space between Durnovo Estate and Hydro-Turbine Shop No. 202 (then known as shop No. 19) was filled with a sea of people. All of the several thousand employees of the plant came to meet the first astronaut. Before giving a speech, Gagarin was taken on a tour of the plant. He was interested in the process of making steam and hydraulic turbines, and he enthusiastically talked to machine operators. “I remember him visiting shop No. 33: he was shown the place where spacecraft assemblies had been welded,” says Vladimir Brainin. “Unfortunately, I didn’t have an opportunity to talk to Yuri Gagarin, even though I was standing next to him then.” With regard to this, it is worth mentioning that, though Gagarin’s ancestors were mainly farmers, there were also workmen in his family. The astronaut’s grandfather Timofei Matveev was employed at Putilovsky (known today as Kirovsky) Plant. Yuri himself studied at Lubertsy Vocational School No. 10, and graduated with honors as a molder and founder. He also attended an evening school for working youths and Saratov Industrial Technical School. “Being a molder at a foundry shop is not easy. The job requires both knowledge and immense physical strength,” he later said. So, the first astronaut did not look around LMZ shops as a mere tourist: he highly appreciated the employees’ efforts, being an equal of the workmen. “Here, remarkable people are doing notable deeds. In the name of all astronauts, I wish you to always work as well as you do today,” Gagarin wrote in the distinguished visitors’ book. Ivan Denisenko You don’t usually see many people at the square between shop No. 202 and Durnovo Estate, where once every year running races start as part of the plant’s sports festival. The fresh breeze from Neva, which is a frequent guest here, especially in the off-season, makes the square seem even larger than usual. It’s hard to believe that it was here, on this square, that the first astronaut – a man who became a legend, a symbol of the era after his flight to space – stood. And it also seems unbelievable that some of the professionals who still work at LMZ witnessed that August meeting and remember even the smallest details. Gagarin spoke to the plant’s workers from a second-floor balcony of the Estate. Unfortunately, in 2003 the whole floor was destroyed in a fire, and the reconstructed building can’t convey all the gorgeous beauty of the original, historic edifice. “I was standing far from Gagarin, as were many others: the square was literally flooded with people,” recalls Konstantin Lapshinov, Lead Design Engineer at Gidroturbomash Special Design Bureau. “In 1957, we all held our breath listening to the beeping sound of the satellite’s signal, and after just a few years, in 1961, man made it to space. It was absolutely unbelievable. By the way, I started working at the plant the same year, in 1961.” “It was a long time ago,” his colleague Vasily Krusanov, another Lead Design Engineer at Gidroturbomash Special Design Bureau, says. “I remember the festive mood; everyone was so happy, and the applause was warm and loud. To tell you the truth, during my 64 years at the plant I have seen a lot of prominent people, including the President of France Charles de Gaulle, the Chairman of the Council of Ministers of the USSR Aleksey Kosygin, and the President of Indonesia Sukarno.” Back then, in 1962, LMZ workers promised Yuri Gagarin that the plant would respond to the challenges of the dawning space era with dedicated work, “cosmic” efforts and feats of labor. And they fulfilled that promise, and this can be seen in the number of machines manufactured for Russian and foreign space stations. The plant’s contribution to the “space odyssey” will remain a key element in its history. 37 38 In quotes Olga Kovaleva May–September 2014 | International (special) issue 1 (3) “WORKING ON ANY PROJECT IS AN INTERESTING, IF AT TIMES SOMEWHAT DRAMATIC TASK” Olga Mikhailovna Kovaleva, Project Manager at the Power Machines’ Sales Directorate, knows why one should speak well of competitors when talking to a client, how one can deal with “translation issues” during negotiations, and why every large project is worthy of a plot for a fascinating novel. “Share your knowledge with your customers, support their initiatives. And one day you will be surprised and flattered to hear on the phone, “It's our station's official meeting. Would you like to join us for our celebration?” “The main objective of the Sales Directorate is to develop a sales strategy in a highly competitive environment. Many companies are trying to attract customers by saying, “Our competitors can’t do anything, but we can!” Most of the organizations use this strategy, and it just doesn’t work! If a competitor is well-known, it’s self-evident that it can’t be a unprofessional company. If you want to stand out among other market participants, you should tell your customers that your competitors work well, that they do certain things in a certain way for a certain reason — but you do the same things differently; and then you should explain how your product differs from theirs and what its advantages are.” “The Sales Directorate provides the holding with orders from foreign and local customers. The international activities of Power Machines are of particular importance, because they help further international cooperation and improve the country’s global image. An increasingly competitive environment urges us to seek new practices, move forward and think of the changes that the next five or ten years will bring to the market.” “The professionals at Power Machines have mastered all the competencies required to prepare new proposals for bidding processes while executing the existing contracts. But further development of these competencies is a continuing process, because the world doesn’t stand still. The company organizes comprehensive training for specialists in all areas and at all levels, which can only inspire respect.” “The most interesting part of working in a foreign market is making contacts and dealing with the “translation issues.” Sometimes customers may not understand the complex technological aspects of our product — and they don’t have to! Hence, it’s very important to speak the same language that they do, edit the translations of letters written by engineers, and keep the client informed about the project status.” “I’ve been employed by the company for 40 years. I started my career as a design engineer at Gidroturbomash Special Design Bureau of Leningradsky Metallichesky Zavod, which I joined after graduating from Moscow Power Engineering Institute, and since 1987 I’ve been working with sales. I can’t imagine doing any job other than my current one. Working on any project is an interesting, if at times somewhat dramatic task that poses a lot of non-routine challenges. Every large and complex project is worthy of serving as a plot for a fascinating novel, at the least a novella. And the company’s successes, as well as personal achievements, depend on the enthusiasm of each sales department employee and their commitment to working efficiently on their project”.
