The main objective of this study is to investigate the phenomenon of water impact underneath the decks of offshore structures due to propagating waves. The decks of offshore structures may be subjected to wave induced loads, which may be not accounted for in the original design. For safe design of offshore platforms, it is important that the hydrodynamic loads and the predicted accurately. In this report, a review of the previous work on this topic with a brief introduction to slamming theory together with a proposed procedure to predict the water impact underneath the decks of floating offshore structures will be presented. Meantime, three dimensional hydrodynamic analysis of a semi-submersible in sea waves has been performed by using the direct boundaryelement methods.
