Wave Effects?
Scotrenewables Turbine
Design Basics:
• Floating, surface piercing. Use of small inexpensive work vessel for installation. Onsite maintenance
• Catenary mooring system – allows the turbine to respond to the dynamic environment
• Passive yaw control, 360º continuous rotation around mooring system
• Fixed pitch, variable speed, counter-rotating rotors
• PTO – gearbox and variable speed induction generator
• Turbine structure approx 200t / MW
