| Abstract: | Through utilizing a new type of polyurethane of high marine environment tolerance,designing related mould and using appropriate forming process,a novel kind of helical strake was got which was 3-start with height 0.25D and pitch 17.5D.According to the experimentation result of offshore VIV(vortex-induced vibration),the suppression efficiency of helical strake exceeded 80% at each towing speed experiment,and the upmost efficiency was as high as 89.0%.Recommendations for the future directions of helical strake research were addressed in the end. |
