The comparison Study on Oceanic Semi-submersible Wind Turbine Platform Mooring System

The most feasible mooring system is selected based on sea conditions and geometic characteristics of floating wind turbine platform to restrict such platform within an acceptable range during operation on the sea,which is one of the most important factors considered for the development of offshore wind energy.This paper takes the 5MW-OC4deepwater semi-submersible floating wind-turbine platform as the reference model,and obtains the amplitude-frequency response curves of this platform,by modeling the semi-submersible floating wind-turbine platform with AQWA software and caculating relevant motion responses within the frequenc domain range,in order to verify the reliablity of numerical analysis.3 type of mooring systems for floating wind-turbine platforms are compared to study influences of changes in mooring systems on the motion response of floating wind-turbine platforms,as well as the tensile forces of mooring cables,under exetreme conditions are analyzed as well.Results have certain referential meaning towards the optimization design of mooring systems for floating wind-turbine platform.
