Abstract

Fishing vessels are designed with a specific mission. That mission is to locate, catch, and preserve fish while out at sea, meanwhile the vessel needed to have good maneuverability. This research describes a study on asymmetrical propeller configuration of a fishing vessel to improve its maneuvering quality. MATLAB-simulink program was used to simulate, the turning circle and the zigzag maneuvers. The simulation program was developed based on the mathematical model for a fishing vessel maneuvering. The mathematical model involved the setting-up a 3 DOF (Degres of Freedom) mathematical model in a modular of MMG (Mathematical Modeling Group) of the hull, propeller and rudder component. The result indicated that twin propeller with asymmetrical had an advantages of turning circle ability of 8% to 14 %, meanwhile the zigzag maneuver 20°/20° had 9 to 20 % 1st overshoot different between left and right heading.                                                                                         Keywords: Configuration, propeller, assymetrical, fisheries, simulation

Abstract

Kapal perikanan umumnya dirancang dengan misi khusus untuk menemukan, menangkap, dan mengawetkan ikan, sementara itu kapal harus memiliki tingkat keselamatan yang baik, biaya operasional yang rendah serta ramah lingkungan. Penelitian ini bertujuan untuk meningkatkan tingkat keselamatan dan pengurangan biaya operasional kapal perikanan 30 GT melalui desain freeboard minimum. Paket program Maxsurf telah digunakan dalam pemodelan dimensi, desain bentuk kasko, prediksi stabilitas dan resistensi pada 4 (empat) model kasko yang dianalisis (K1, K2, K3 dan K4). Hasil penelitian menunjukkan bahwa bentuk kasko K2 dengan rasio dimensi utama lebih lebar (L/B=4,98; B/D=3,26; B/T=4,80; D/T=1,47) memiliki tingkat stabilitas yang lebih baik dibandingkan 3 (tiga) model kasko lainnya (K1, K3 dan K4), sementara pengurangan nilai resistensi tertinggi ditunjukkan oleh model bentuk kasko K3 dengan rasio dimensi utama lebih ramping (L/B=6,43; B/D=2,78; B/T=4,09; D/T=1,47). Secara umum, keempat model bentuk kasko yang dianalisis layak dioperasikan sesuai dengan kriteria IMO.
