Design requirements for floating offshore wind turbines

 

This part of IEC 61400 specifies additional requirements for assessment of the external conditions at a floating offshore wind turbine (FOWT) site and specifies essential design requirements to ensure the engineering integrity of FOWT’s. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime.

This Technical Specification focuses on the engineering integrity of the structural components of a FOWT, but is also concerned with subsystems such as control and protection mechanisms, internal electrical systems and mechanical systems.

A wind turbine shall be considered as a FOWT, if the floating sub-structure is subject to hydrodynamic loading and supported by buoyancy and a station keeping system. A FOWT encompasses five principal subsystems: the RNA, the tower, the floating sub-structure, the station keeping system and the on-board machinery, equipment and systems that are not part of the RNA.

This Technical Specification is applicable to unmanned floating structures with one single horizontal axis turbine. Additional considerations may be needed for multi-turbine units on a single floating sub-structure, vertical-axis wind turbines, or combined wind/wave energy systems.
