YOUR FIRST CLASS SEABORNE SOLUTION
The IMOIIMAX tankers will represent
the most sophisticated vessels in the
Stena Weco fleet.
The IMOIIMAX is an important step in our common pursuit to create
a more sustainable shipping concept combined with a flexible design
to offer our customers better business solutions at competitive freight
rates. The IMOIIMAX is designed to carry IMO 2 and 3 cargoes as
well as clean and dirty products. The vessels are all equipped with
eighteen cargo tanks of max 3,000 m3 capacity as well as a nitrogen
based inert gas system.
Hull lines, engines and the propeller have been extensively tested and which resulted in an
extraordinarily well performing design. No stone has been left unturned to ensure reduced
bunker consumption as the vessels are equipped with the latest concepts in main and
auxiliary engine designs. These engines are optimized to be the best in their segment for
overall performance and reduced fuel consumption. Less emissions from reduced fuel
consumption decreases the environmental impact.
The key words for the IMOIIMAX are innovation and performance.
When merged with the best technology available, innovation
ensures efficient and flexible carriage of cargoes.
Performance means safe and cost efficient
transportation for our customers.
Flexibility is paramount to be competitive in the
Tanker segment. Ships must be able to carry a wide
range of cargoes in smaller and specialized parcels giving
higher freight per ton. Also increasingly important in this kind of
trade is to be able to quickly switch between various types and grades
of cargoes.

Stena Weco – the joint venture
between Stena Bulk and Weco
– has embarked on the journey
towards being the market-leading
operator in the MR tanker segment
specializing in cross trading.
OPTIMIZED DESIGN FOR FLEXIBLE EDIBLE
O I L S O P E R AT I O N A N D C A R G O F L O W
After a large number of towing tank tests and extensive development, Stena Teknik has
together with Guangzhou Shipyard in China succeeded to obtain a design that is probably
the most efficient Eco MR Tanker existing today. Completely new and revolutionary hull
lines together with specially designed propeller, rudders, engines, exhaust gas energy
recovery and onboard systems will reduce the overall energy consumption to a minimum.

INTEGRATED BRIDGE SYSTEM
In heavy weather the wind resistance can become significant.
By smart design of the accommodation the IMOIIMAX benefits
from less wind resistance than other similar vessels.
The vessel has an integrated bridge system that allows
access of all essential navigation information from the
centralized workstations. System components include
2 radars, 3 ECDIS, conning display, 2 gyro compass, auto
pilot, 2 DGPS, Navtex, speed log, AIS and echo sounder.

Thanks to the eighteen cargo tanks arrangement no single tank is
larger than 3,000 m3. Consequently, the IMOIIMAX can load a full
IMO 2 cargo in each tank.
Instead of simpler coated mild steel piping with flanged couplings
the cargo piping on IMOIIMAX is of stainless steel in order to comply
with FOSFA recommendations and the chemical trade.

IMOIIMAX is equipped with a ship performance
system for better and efficient onboard control
of the systems resulting in energy savings
and reducing the environmental footprint of the
vessel.
High performing well proven cargo tank coating ensures that the
Charterer will have full flexibility to carry an extensive spectrum
of products and chemicals at desired temperatures.
The deep well hydraulic FRAMO cargo pump system provides full
flexibility so that all cargo pumps can be run and controlled individually,
at the same time. Consequently, a high cargo discharge capacity is
offered together with a high degree of flexibility of cargo circulation.
LA TEST MAIN ENGIN E D E SIG N
The MAN 6S50ME-B-9.93 type main engine is the latest version with
higher fuel efficiency at part load operation compared to earlier versions.
IMOIIMAX is optimized to perform well over a range of both loading
conditions and speeds. The low load optimization of the main engine
including an Exhaust Gas By-pass contributes to an overall excellent
performance.
With an auto-tuning system the combustion process in each cylinder is
continuously automatically controlled for optimal engine performance in
all conditions.
TWO OIL FIRED BOILERS AND ONE EXHAUST GAS
C O MP O S I T E B O I L E R
Two oil fired boilers provide for flexibility and redundancy which is of
particular advantage when carrying heated cargoes. In many instances
only part steam heating capacity is required. In such cases, both boilers
can be run efficiently instead of having only one big boiler operating at
non-preferable conditions.
A UX ILIARY ENGINES PAR T L O AD O PT IM IZ E D
Normally auxiliary engines are fuel optimized for high load operation
rather than part load operation. Part load operations are becoming a
higher percentage of normal operations. For IMOIIMAX, the new auxiliary
engines have been part load optimized improving the overall performance
and reducing fuel consumption.
The vessel is also equipped with an exhaust gas multi-inlet composite
boiler as one of the very first installations. This boiler not only recovers
energy from the main engine’s exhaust gas but also recovers the
exhaust gas energy from two of the auxiliary engines.
In addition, the boiler has an oil fired section providing for an adapted
steam production to suit the vessel’s domestic steam demand without
the need to run the bigger oil fired boilers.

Clean Nitrogen instead of traditional inert flue gas will decrease the
time between discharge and loading due to faster tank cleaning.
No need of portable nitrogen bottles for purging and/or cargo tank
padding.
From a fuel efficiency point of view inert gas generation by means of
a nitrogen generator is also more fuel efficient compared to a
traditional inert gas generator.

The tank cleaning system provides for four tanks to be washed
simultaneously with heated as well as cold sea and fresh water.
Fulfilling Lloyd’s Register voluntary class notation Effective Tank
Cleaning, there has been an arrangement of the tank cleaning
machines to minimize the shadow areas which maximizes efficient
tank cleaning operations in turn minimizing the time between
discharge and loading.
