Why not floating ?
• Visible is ugly – A fleet of canoes in the water is nicer to look at than a coal,
gas or nuclear plant…and hard to see at all from the shore
• Wave loads? – Design and basin test for it. Experience > 35 years
• Breaking mooring lines? – Same as above. If an FPSO breaks loose, the damage would
be much worse.
• Hazard for ships? – A hazard you can see at the surface is better than an invisible
underwater surprise
Lower cost, lower risk, more energy
Higher energy production
Easy installation
Easy access Protected equipment Dry connections
System is designed for minimum installation costs
• Pre-installed mooring system
• Floating tow-out and hook-up, no offshore heavy lifting
• Scalable: Adapt only anchor points for different seabed conditions
• Reduced draft, raising turbines
System is designed for safe and easy operations and maintancne to minimize costs
• Option 1: Direct access offshore to inspect, repair or replace vulnerable electronics
Operations and maintenance • Option 2: Visual inspection of turbines by camera from platform
• Option 3: Lift turbines above water for further inspection and problem solving
• Option 4: Disconnect unit and tow to shore, with relatively simple vessels without any heavy lifting
Sites: Canada – Bay of Fundy, Nova Scotia
• Full scale
• Phase 1 a): 2 MW Phase 1 b): up to 16 MW
• Berth holders: Minas Basin, Siemens, Bluewater
