Abstract

A very good seakeeping vessel is able to operate effectively even in high sea states and also the passengers and the cargos are ensured in good conditions. The motions of a high speed boats are highly influenced by speed and dynamic forces even in encounter frequencies so that the assessment of seakeeping ability of the design craft in an early stage needs to be calculated for all three motions and for all ralative wave headings. In this paper, it concludes that RAO and RMS values of the catamaran's 3 motion are calculated according as the variation of Beafort scales and ship's speed. The ship motion response of the catamaran based on the RAO and RMS by encounter angles and speed was calculated.

내항성능이 우수한 선체는 나쁜 해상상태에서도 효과적으로 운항이 가능하고, 여객과 화물을 안정된 상태로 유지시키게 된다. 이러한 선체의 운동은 선속과 파도의 조우주파수와 밀접한 관계를 가지고 있다. 운동응답에 대한 평가는 입사파에 대하여 3자유도 운동에 대한 계산이 수행되어야 한다. 따라서 본 연구에서는 카타마란형 레저보트의 선형설계를 수행하여 이에 대한 운동성능을 고찰하고자 하였다. 조우각과 선속의 변화에 따른 카타마란의 3자유도에 대한 RAO 및 RMS 값의 반복적인 평가를 통하여 양호한 운동응답을 보였다.
