Floating wind turbine
A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where bottom-mounted towers are not feasible.Locating wind farms out at sea can reduce visual pollution while providing better accommodation for fishing and shipping lanes.In addition, the wind is typically more consistent and stronger over the sea, due to the absence of topographic features that disrupt wind flow.Floating wind parks are wind farms that site several floating wind turbines closely together to take advantage of common infrastructure such as power transmission facilities.
