Abstract

When typhoon approaches, ship normally drops her anchor at proper anchorage for sheltering. If an anchored ship is under the influence of typhoon, she can keep her position when the external force and counter force is balanced. Where, external force is induced by wind, wave and tidal currents while counter force is induced by holding power of anchor/chain and thrust force of main engine. In this study, authors presented a method to analyze theoretically the limit of external force for the ship to keep her position without being dragged and, to check the validity of the method, applied this to the ship which had been anchored in Jinhae Bay when the typhoon MAEMI passed on September 2003.

태풍이 내습하면 선박은 이를 피해 적절한 묘박지를 선정하여 묘박하게 된다. 묘박 중인 선박은 일단 태풍의 영향권에 들어가면 바람, 파도 및 해${\cdot}$조류에 의해 발생되는 외력과 이에 대응하여 묘와 묘쇄에 의한 파주력 및 기관 추진력에 의한 선박의 대응력이 서로 균형을 이룸으로써 주묘되지 않고 안전하게 견딜 수 있다. 본 연구에서는 묘박 중인 선박이 주묘되지 않고 견딜 수 있는 외력의 한계를 이론적으로 분석할 수 있는 방법을 제시하고, 이를 2003년 9월 태풍 매미가 내습했을 당시 진해만에 묘박했던 선박에 적용해봄으로써 그 타당성을 검토하였다.
