Floating Wind Turbines

Fukushima coast, Japan Technology and advantages Instead of bottom-fixed phycical foundation, floating platforms are attached to the seabed with mooring lines. Three main types of floating wind platforms Ballast stabilized Tension Leg Platforms Buoyancy Stabilized (Hywind) BUOYANCY STABILIZED Technology and advantages Access to previously inaccessible waters. Commissioned and assembled at the quayside. Foundations not necessary 1. Sea life disturbance minimized 2. Reduced geotechnical requirements Also 3. Considerably less noise and visual pollution 4. Greater energy/cost value Initiatives - Hywind Developed by Norwegian energy company Statoil ASA World's first full-scale floating wind turbine 10 km off the soutwest coast of Norway 100 meters beneath the sea's surface Can be employed at ocean depths of 120 to 700 meters
