英文摘要：With increasing demand for energy and the enhancement of environment consciousness, the natural gas as a clean energy has drawn more and more attention. For long-distance offshore transportation of liquefied natural gas, undoubtedly, LNG vessel is the most effective and economical choice. Seakeeping performance as an important indicator of the safety performance of the ship, it should be taken into account during the progress of designing and operating. In present paper, the soft SESAM of DNV is used to calculate the six degree motion response of LNG ship in regular waves, studying the influence of forward speed and wave direction. According to relevant requirement, ship model is made and its seakeeping experiment is conducted, and then compared the calculated result with the experiment result. The results showed that:the wave direction has great influence on its motion response, heave and roll is the largest when encountering transverse wave, while pitch is the largest at the case of head sea; the variation trend of calculated result and experiment result has a good agreement.
