Abstract

It is inevitable to maintain safety when vessels cannot stay inside harbour due to stormy weathers. Authors summed up nationwide questionnaire about present offshore harbour refuge. It reveals the necessity of consideration about wave forces in anchored ship motions. Numerical simulation models are newly constructed to reproduce anchored ship motions under waves and winds. Especially, anchored ship motions have not been compared between catenary method and dynamic methods of anchor chain forces. Here, ship motions are simulated to compare differences against the casualty of 60,000DWT class grain carrier in Japan. Anchor chain forces become larger in the lumped mass method than those in the catenary method. They also become larger when we consider wave forces, so it means that proposed model of safety evaluation should be used.
