정박된 선박의 운동 및 계류력 분석

초록

Mooring is the operation of securing a ship to a wharf or quay by means of ropes or chains. A moored ship need not necessarily be truly stationary. It may be free to rise and fall with the tide or the loading and unloading of cargo or to oscillate in response to the action of the environmental forces. In this respect a moored ship is restricted to a limited amount of movement within well-defined bounds. This study is intended to analyze the tension of mooring lines by a FEM program, as the current velocities and working directions are varied. The motion of a berthed ship is studied concerning with the wave periods and the direction. Also the behavior of the modeled vessel are investigated for a berthed condition.
