Comparison of Resistance for Three 10,000 Ton Ships: a Monohull, a Catamaran and a Trimaran

10,000톤의 단동선, 쌍동선, 삼동선 저항 비교

Preliminary conceptual design of hulls is developed and a theoretical evaluation study performed for the comparison of the hull concepts. Systematic variation of the side hull location is carried out to find an optimum position of side hulls for a trimaran by CFD computation. In order to compare computed results, the model test of trimaran was carried out. Shallow water effect is considered due to the route which has critical water depth of 20m for the design speed and investigated on the condition of different speeds and water depth by the numerical computations.
