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
Easy installation
Easy access
Protected equipment
Dry connections
Higher energy production
Installation
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
Operations and maintanance
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
• Option 2: Visual inspection of turbines by
Operations

maintenance
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
Thank you!
