Study on the Influence of Chamfer Perforation on Heave and Pitch of a Single Floating Platform

Abstract The aim of this work is to study the influence chamfered perforation and chamfering on heave pitch motion a single floating wind power platform with an anti-heave device. Firstly, hydrodynamic performance body different chamfers, or without perforation, calculated analysed. Secondly, model 35° captured studied in towing tank. results show that when wave height large period small, perforated device has certain effect. When are suppression effect more obvious than non-chamfered perforation. large, better In experimental research, restraining under most working conditions, obviously heave.
