There is a limitation for a ship which is sailing on sea to gather weather and seastate informations. To make up for this weakness, land organizations can gather wider variety of information and evaluate the seakeeping performanceon ship. And supply this information to the ship. In this study, calculated the response amplitude of shp motions with the weather information provided in real time, the nominal speed loss with obtaining increase of resistance caused by wave and stochastic process of the seakeeping performance elements. And the results have been achieved to develop a system which can evaluate the synthetic seakeeping performance. Using this system, the results have been studied to determine the feasibility of using simulation in actural operation onboard ship.
