Pengujian Performa Prototype Kapal Platform Supply Vessel Tipe Monohull Dengan Variasi Kemiringan Turn Fin Dan Trim Tab Untuk Kontes Kapal Indonesia

ABSTRACT
Monohull-type Platform Supply Vessels (PSVs) play a crucial role in supporting offshore operational activities. Although the monohull hull design provides structural efficiency, these vessels are prone to stability issues and hydrodynamic resistance under dynamic conditions. Therefore, additional components such as turn fins and trim tabs are required to enhance vessel performance. This study aims to evaluate the influence of varying the inclination angles of turn fins and trim tabs on maneuvering speed, straight-line speed, resistance, and vessel stability. The experimental method was applied to a monohull-type prototype with inclination variations of 5°, 10°, 15°, and 20° for both turn fins and trim tabs. Testing was conducted directly in an open-water basin, with parameters including straight-line speed, maneuverability, resistance, and righting arm (GZ) values under varying loads ranging from 0 to 5 kg. The results indicate that a 15° turn fin angle achieved the highest maneuvering speed of 1.82 m/s, accompanied by the highest resistance of 23.56 N. At a 15° trim tab angle, the lowest resistance value of 7.96 N was observed, contributing to improved straight-line motion. The combination of 15° for both the turn fin and trim tab proved to deliver the most optimal overall performance. Vessel stability increased in line with additional loading, with the highest righting arm (GZ) value of 0.01138 m recorded at a 5 kg load. In conclusion, the adjustment of turn fin and trim tab angles within the 5° to 20° range significantly enhances the hydrodynamic performance of the monohull-type PSV prototype.
