Abstract

Every ship, that is still actively operating in shipping must pay attention to repair or maintenance in accordance with classification standards. This was needed by management or ship owners to carry out maintenance planning. The shipyards as repair services, there are often obstacles during the repair process that cause the repair time to be longer. This is caused by limited work equipment, delivery of materials that are not in order, and lack of technical equipment. The purpose of research is to evaluate the risk of ship repair delays so there are no failures or delays in ship repair. The method used is the FMEA method (Failure Mode and Effect Analysis) to measure each failure in each activity that affects ship repair. The results showed an assessment score in the form of a Risk Priority Number (RPN) consisting of activities: amount of cutting machines is still limited with a score of 309.83, painting and welding failures at the same time with a score of 267.08, materials that come are remachined to fit the needs with a score of 335.06 and inadequate transportation equipment with a score of 294.16. Improvements made in the form of preparing amount of work tools before the work is carried out, conditioning the order of work according to the schedule and adding backup transportation.

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.
