Abstract- Following a few catastrophic accidents involving mobile offshore drilling platforms, various studies were carried out to investigate the adequacy of stability criteria applied to offshore mobile platforms which was derived on an empirical basis considering service experience accumulated for ships over many years. In this study, a twin hulled semi-submersible model sea-keeping performance was studied successfully in the wave tank for regular and irregular waves in sea, quartering and beam orientations. Results showed that the model RAOs follow the same tendency for regular and irregular wave.
