主　　题：wave impact load semi-submersible wave breaking energy loss shoaling effect 

摘      要：Semi-submersibles for offshore oil exploration and exploitation often suffer from severe wave impacts in extreme ocean *** to the complex wave interactions among structural components of semi-submersibles,in-depth analyses on the characteristics of wave impact events are of significance for both industry and *** experimental study was carried out to investigate the local wave impact loads on a semi-submersible,with focus on understanding the wave impacts by identifying typical impact *** criteria are proposed to classify major wave impacts on the semi-submersible into six modes and two *** results show that the classification is reasonable and provides valuable information for studying wave impacts on *** incident wave characteristics at the fore column of the semi-submersible have important influence on the wave impact *** fore-column dominating wave impacts exert the most intense loads on the fore column and feature well-developed breaking waves or slightly breaking waves at the fore ***,the aft-column dominating wave impacts exert the most intense loads on the aft column or the deck bottom and feature non-breaking waves at the fore *** loss during the fore-column impact weakens the impact severity on the aft column in the fore-column dominating wave *** shoaling effect of the submerged pontoon and different motion configurations of the platform result in higher occurrence rate of the aft-column dominating wave *** impact modes are also distinguished by different spatial distributions of wave impact loads.
