Abstract

In shipbuilding work, the risk of delays must be analyzed and anticipated so that such delays do not occur and cause losses for both parties. This study aims to calculate the risk of a shipbuilding project using the Failure Mode and Effect Analysis (FMEA) method. The final result obtained is the result of the calculation of the Risk Priority Number (RPN) in determining what risks can af fect shipbuilding work. There are two jobs with RPN value > 200 which are classified as High Risk namely errors in lofting and damage to the pulley block as a supporting tool. The plans for risk management with the highest RPN value are then discussed with th e shipyard. Risk mitigation is carried out on the possible risk of errors in lofting, namely by adding worker personnel in the loft ing workshop who serve as supervisors and examiners. While the risk of breakage of the trough can be overcome by paying attention to the inventory and also the condition of the tool.

Abstract

A ship that is still carrying out sailing activities must always be in a state that is in accordance with the classification and statutory. Maintenance or repair is needed for the ship in order to stay in good condition and fit to sail. In a ship repair project, there are several important aspects that need to be considered in order to complete project activities quickly and precisely. PT. XYZ has carried out ship repair activities, but the repair activities have been delayed due to weather factors, and the late procurement of spare parts. This research was conducted by analyzing the three models of scheduling fiberglass ship repair projects using Microsoft excel and using the CPM (Critical Path Method), PDM (Precedence Diagram Method) and PERT (Project Evaluation and Review Technique) methods. Results from the CPM method on 48-day A scheduling, 33-day B scheduling, and 21-day C scheduling. Pdm method results scheduling A 48 days, scheduling B 33 days, and scheduling C 21 days. In the PERT method the project can be completed in 48 days which is 48.67%, scheduling B 34 days 5 hours 21 minutes with the possibility of a KN ship repair project. RB 309 Ternate 01 can be completed in 48 days i.e. 99.35% and scheduling C 22 days 5 hours 21 minutes with the possibility of a KN ship repair project. RB 309 Ternate 01 can be completed in 48 days which is 99.99%.
