Design of Floating Offshore Wind Turbine (FOWT) “SelfAligner”
2020The CRUSE Offshore GmbH has invented an innovative floating structure foundation for offshore wind turbines by using the forces of nature. The structure is a semi-submersible, self-aligning platform. The foundation is moored at a single point and uses a turret buoy to rotate freely around its anchor point.

Fatigue Assessment for Gearbox of a Floating Offshore Wind Turbine (FOWT)
Volume 1: Offshore Technology; Structures, Safety and Reliability; Materials TechnologyAbstract Due to severe working conditions, the gearbox of a floating offshore wind turbine (FOWT) is prone to fatigue damage. Fatigue failure of the gearbox may lead to significant economic losses and even potential safety incidents. Therefore, fatigue assessment for the gearbox of a NERL Spar type 5MW FOWT is performed in this paper ...
