ANALYSIS STABILITY SYSTEM RUDDER ROLL OF SHIP CARGO A. PIONEER

Cargo Ship in dire needs good maneuverability while operating in the sea. Maneuverability is influenced by the ship's steering system which also affects the rolling stability of the ship. Rolling stability control plays an important role in the ship that can return the ship to its normal state in response to sea wave disruption, where Rudder roll is able to control the heading until the rolling motion is reduced. The disturbance used is a sea state 1 and sea state 7 in wave linear disturbances. The higher the level of interference, the longer the rolling stability reaches the steady state. The stability performance of rudder roll stabilization system has been in accordance with existing stability parameters. The maneuverability of the rudder roll stabilization system with 200 heading has an advanced distance of 275 meters in diameter.
