An Experimental Analysis of the Impact of Green Water on Offshore Platforms with Green Water Protectors of Various Shapes

摘要

Green water impact occurs frequently on offshore platform due to waves with a height greater relative to the freeboard of the structure. This phenomenon exert a large impact load in a considerable impact on the deck. In this paper, offshore platform models with green water protectors of various shapes were fixed to the center of a 3D wave tank to measure the impact pressure at various points. The impact pressure differed according to the protector shape. Also, waves creeping up the protectors were observed. The protector shape that exerted the lowest pressure impact on the deck will be useful in design of offshore platform and deck equipment.
