摘要：The cost of energy produced by offshore wind turbines is considered to be higher than land
based ones because of the difficulties in construction, operation and maintenance on
offshore sites. To solve the problem, we propose a concept of a wind turbine that is
specially designed for an offshore environment. In the proposed concept, a floater of
revolutionary shape supports the load of the wind turbine axis. The floater rotates with
the turbine and the turbine axis tilts to balance the turbine thrust, buoyancy
and gravity. The tilt angle is passively adjustable to wind force. The angle is
30° at rated power. The simplicity of the system leads to further cost reduction of offshore
power generation.
