Abstract

Ship repair is a project that is short in process so that time is an important element in its completion parameters. Delay is something that can happen to a job. A job experiencing delays must have a cause that affects the work. Causes of delay in the case of ship repair are poor time management, less skilled human resources, the addition or development of work. But whatever the obstacles, shipyards are still required to complete the ship repair process in a timely manner. Seeing this problem, this research was conducted to provide input in connection with the strategies used by PT XYZ in overcoming the delay factor in the repair of the KM Binaiya ship. In the research to support this thesis, the Bayesian Networks Method is used to analyze the factors that cause delays in ship repairs. After risk identification using the Bayesian networks method. The highest risk is replete activities as minor categorized, where the caused tank cleaning work related to hazardous waste, which must be cleaned to be safe for hot work with a risk score of 0.108. The second cause is installation of scaffolding for replete work facilities at height with a risk score of 0.054.

Abstract

Ship Movement is an important factor in shipbuilding. In determining the ship's maneuverability, there are many aspects that must be considered in the design, namely resistance and angle of attack of the waves. In determining the angle of attack of the waves, the test uses the trigonometry principle to determine the angle of attack of the waves. Where the results of the 3 maneuvers of the Heave, Roll and Pitch ships at speeds of 0 knots, 0.389 knots, 0.778 knots, 1.166 knots, 1943 knots, it is known that the displacement model ship can be used in an open area with a set scale.
