Global performance analysis of 5MW WindFloat and OC4 semi-submersible floating offshore wind turbines (FOWT) by numerical simulations Conference Paper uri icon


  • Copyright 2017 by the International Society of Offshore and Polar Engineers (ISOPE). In recent years, floating offshore wind turbines (FOWTs) increasingly draw more attention in deeper oceans and various types have been suggested. WindFloat and OC4 semisubmersible FOWTs are popular concepts among them and 2MW WindFloat (WF) and 1:8 scaled OC4 FOWTs were successfully installed and demonstrated in real fields. The two types are similar in that both have three cylindrical columns and use catenary mooring for station-keeping. However, there are some differences between OC4 and WindFloat FOWTs including the thickness of heave plate at the bottom of each column, the location of tower, and the use of ballast water for heeling control. This paper presents a comparison of the global performance of the OC4 and WF hulls for the same environmental and control conditions when adopting the same 5MW wind turbine and catenary mooring system using the turbine-floater-mooring fully coupled simulation program.
