Abstract

Simulation on towing tank that require large costs, makes the ship’s owner have to pay more
to find their ship resistance value. Computational Fluid Dynamics (CFD) can be the substitution to
determine the resistance. This research discuss the effect caused by the variations application in wavepiercing forms on the MV. Saint John Paul II catamaran High-Speed Craft (HSC) at service speed to
find the smallest resistance value among them. The original model of the ship was obtained during TEEP
research visiting program at National Taiwan University. 3D modeling on the wave-piercing variations
was using Rhinoceros6 software. Analysis to find the value of resistance was using CFD method with
the help of Orca3D and “SimericsMP+ForMarine” softwares. Variation was applied to the wavepiercing only, so it does not change the hydrostatic and stability of the initial model that has been
validated. Based on the transient CFD result at the speed of 38 knots, the researcher has obtained the
axe bow is having the smallest resistance value with 1101kN, followed by the raked bow, that have
1126,35kN resistance value, and the original bow with 1137,7kN.
