Analysis of Fin Stabilizer Base on NACA 0010 in Fast Patrol Boat to Reduce Appendage Resistance on Numerical Method

Abstract

The main function of the fin stabilizer on patrol boats is anti-rolling and providing comfort for ship personnel. However, the installation of the fin stabilizer has a consequence in the form of appendage resistance of the ship. This study analyzes the magnitude of the appendage resistance due to the installation of the NACA 0010 stabilizer fin mounted on a 60m patrol boat at an angle of 0º. Reduction of ship resistance is expected to improve the ship performance which then can optimize the use of fuels and minimize pollution. In the early stages, the bare hull was validated with the results of the model test on the towing tank with a resistance difference of less than 3%. Based on the simulation results, it is known that the average resistance value of Fine Marine Numeca is 1.87% higher than the resistance value of the Maxsurf software. From the results of testing the appendage resistance value with 3 variations of the shape of the NACA 0010 fin, it is known that the appendage resistance value of fin stabilizer 2 is 1.04%, fin stabilizer 1 is 1.26% while fin stabilizer 3 is 1.6%. The appendage resistance of fin stabilizer 2 is smaller than the variation of fin stabilizer 1 and 3 models.
