Irving, Limited - Project Solutions • Outside the Integrated Logistics division, Atlantic Towing also has synergies with other companies in J.D. Irving, Limited • Irving Project Solutions created as a way of coordinating and integrating J.D. Irving, Limited companies as required • Below are some of the companies that are engaged in the Tidal Power Industry 5 Atlantic Towing Company Profile • Provides extensive marine services; • Ice management • Ocean and coastal towage • Wide range of barging services • Harbour and terminal towage • Offshore support • Anchor handling • 475 office and sea staff • Locations; • Saint John, NB • Halifax, NS • St. John’s, NL • Port of Spain, Trinidad 6 Atlantic Towing Company Profile • A modern Canadian, OSV, tug and barge fleet; • 10z-Drives Tugs, plus 4 on order • 6 Conventional Tugs • 5 Barges • 9 Offshore Support Vessels, plus 4 on order • Global Experience; • Eastern Canada • Canadian Arctic • Greenland • Caribbean • North Sea • South America 7 World Class Management • Integrated Quality, Health, Safety, Environment & Security management system • One of first marine service providers to become certified and compliant to ISO 9001 and ISO 14001 • Industry leading training for office and sea staff • Continuous improvement programs using Lean and Six Sigma methodology 8 Focus on Safety • Atlantic Towing continuously strives to improve its Safety Culture; • Zero tolerance policy for critical activities • Formal Investigation of Incidents • Behavioral based safety observation and hazard identification program • Robust safety orientation and mentorship program • Risk based decision making approach to conducting high hazard investigation • Industry leading safety training and workshops for all employees 9 Experience in Tidal Power Industry • Deployment/ retrieval of 1st tidal turbine in Bay of Fundy • Key success factors • Planning • Experience • Communications 10 Experience in Tidal Power Industry • Challenges: • Slack tide window • Turbulence during slack tide • Positioning • Reconnection 11 Developing New Methods • Test run – barge handling off Parrsboro and in Saint John Objectives • 1) Demonstrate ability to maneuver large barges. Route tracking or holding station • Cable laying • Turbine deployment/ retrieval • 2) Help lower cost of Tidal project development by utilizing locally available assets 12 Test Run – Parrsboro 13 2nd Test Run – Saint John 14 Challenges in Developing New Methods • Results: Encountered significant challenge • Maintaining control • Operator reaction time/ precise coordination • Assessment: • ASD tugs provide potential for great maneuverability/ control • Difficult to coordinate manually • Conclusion: Automation needed to increase the ability to coordinate thruster vectors and maximize station keeping 15 Next Stage of Development Addressing the Challenges • To address the conclusions out of the test run Atlantic Towing has worked with key suppliers to develop a system for supporting deployment, retrieval and other associated scopes in the Tidal projects which is: • Lower cost • Relatively easy to mobilize • Adaptable to a variety of platforms • Operationally effective in high current environments 16 Introducing TADPos (Tug Assisted Dynamic Positioning System) 17 TADPos – How it Works • Automatically maintains position and heading • • • • Position reference sensors Wind sensors Motion sensors Gyro compasses • All sensors feed into computer program • Computer program calculates steering angle and thruster output for each thruster 18 Inside the Control Box 19 Plug & Play Modular DP System • Key Features - Recap • Containerized DP system installed on the deployment platform (barge, catamaran, etc, what ever is required) • DP system equipped with mathematical model of the vessels wind and current drag profile • Range of external sensors for all environmental data input • External sensors combined with mathematical model of vessel profile allows computer to calculate steering angle and thruster output • External control and power plugs that connect to any number of ASD tugs • Modifications to tugs to allow remote control by DP system 20 Plug & Play Modular DP System • Key Benefits • Eliminates need for mobilizing/ demobilizing of high cost assets and equipment (locally available, quick and easy to mobilize) • Installation/ removal relatively simple and low cost • Flexible, can be installed on a variety of platforms depending on turbine design or scope of work needed • Operationally effective at aligning/ coordinating ASD tug’s thrusters providing greater control in high current environments • No long term commitments required for usage, once scope of work complete, ASD tugs and DP system can be demobilized and return to normal port operations in Halifax or Saint John 21 Working Together to Advance the Tidal Power Industry in Atlantic Canada Thank You 22
