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 waveswith a height greater relative to the freeboard of the structure. Thisphenomenon exert a large impact load in a considerable impact on thedeck. In this paper, offshore platform models with green water protectorsof various shapes were fixed to the center of a 3D wave tank to measurethe impact pressure at various points. The impact pressure differedaccording to the protector shape. Also, waves creeping up the protectorswere observed. The protector shape that exerted the lowest pressureimpact on the deck will be useful in design of offshore platform and deckequipment.
