Study on the Characteristics of Maneuvering Ferry Vessel as Effect of the Sea Waves

Abstract

Abstract Wave is one of the natural phenomena that gives effect to the cruise ship. The energy produced by the wave is very large that makes the ship turn directions. Therefore the turn has an error coordinates of the starting point of a ship. Deviation of the coordinates has made a further distance and increase fuel consumption, so the operational costs being higher. The research would predict the drift angle, the ship speed and rudder angle to be used after the ship got the influence of wave by taking into account the motion of surge, sway, yaw. Simulations are performed by using Delphi software, with variations of the wind height of 0.5 m, 1 m, 1.5 m, and 2 m, the wave flatness of 0.01, the speed of the wind of 0 and 10 m/s and incoming wave direction 0° - 180° on the side of the ship. It is obtained that the biggest of drift angle happened on 50° wave direction. The biggest of rudder angle happened on 110° wave direction while that fastest ship speed happened on 160° wave direction.
