Experience in Tidal Power Industry
• Deployment/ retrieval of
1st tidal turbine in Bay of
• Key success factors
• Planning
• Experience
• Communications
Experience in Tidal Power Industry
• Challenges:
• Slack tide window
• Turbulence during slack tide
• Positioning
• Reconnection
Developing New Methods
• Test run – barge handling off Parrsboro and in Saint John
• 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
Test Run – Parrsboro
2nd Test Run – Saint John
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
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
Introducing TADPos
(Tug Assisted Dynamic Positioning System)
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
Inside the Control Box
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
• External control and power plugs that connect to any number of
ASD tugs
• Modifications to tugs to allow remote control by DP system
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
Working Together to Advance the Tidal
Power Industry in Atlantic Canada
