OPTIMASI RESPON GERAKAN KAPAL IKAN CATAMARAN TERHADAP GELOMBANG REGULLER

Abstract

This study was conducted to determine if the motion performance catamaran-type fishing boat, through the vessel response to beam waves of sea, sea and head following sea causing oscillation motion in six degrees of freedom. Boats were used as models are aboard ship optimization results comparison with the size of the main LBP 16.0 m; B 6.0 m; T H 4.0 m and 1.5 m. Ship modeled using the program maxsurf dongle, then the model is analyzed using Seakeeper to know RAO vessels such as heaving, rolling and pitching. Input data such as speed boats, heading angle and the type of wave spectrum to show the information entered for the vessel response. RAO's big heave motion maximum occurs at a speed of 14 knots towards 180° with RAO value of 3.389 m.m-1 at a frequency of 0.41 rad.s-1 , the maximum value is 135° of the roll angle of attack occurs when the ship's speed is 0 m-1 .s-1 with a value of RAO 1.34 deg.m-1 at a frequency of 1.67 rad.s-1 , while the value of the minimum roll occurs at a speed of 14 knots with an incidence angle of 135 o RAO value 2,096 deg.m-1 at frequency 1:11 rad/s and maximum use values pith occurred on the ship's speed of 14 knots with an incidence angle of 180 RAO value of 5.66 deg.m-1 at frequency 1:27 rad.s-1. From the research results can be conclude that fish-boat this type of catamaran has a good performance while operating at sea.
