Abstract

Ship repair involves repairing ship parts that are damaged and do not comply with class eligibilityrequirements. The completion of ship repair projects in shipyards often faces obstacles that cause delays in thecompletion of the project. The purpose of this research is to identify the factors causing delay in the repair ofAHTS 65.5 meters ship using the FTA method. It is expected that if the cause of the delay in the ship repairprocess is known, it will be used as a benchmark for predicting delays in future repairs. This research uses FaultTree Analysis (FTA) technique, which is an analytical method for identifying failures in a system. There are twotop events based on the FTA analysis, namely piping work with 13 basic events and engine room work with 14basic events. There is one basic event with a high probability value in piping work, namely the purchase ofimported materials. While the engine room work produces one basic event with a high probability value, namelythe purchase of imported materials. The purchase of imported materials are the predominant causes of delays inship repair projects, so mitigation measures should be taken to prevent future delays.

Abstract

A schedule is crucial to the success of a project so that it is completed within the specifiedtimeframe. Construction of a block on a tugboat is one of the projects used as a case study. The aim of timeestimation is to determine the length of time required to complete a block with the stages of work involved. Inorder to ensure the work process runs on a schedule, a time estimation is done before the work is performed.This data is processed via a computer program. Microsoft Project is a familiar application used in projectmanagement or to assist in the processing of a project. The purpose of this study is to estimate the constructiontime of Block 1 and the work in the critical path on the 35-meter ASD tug ship. In this study, researchersobserve and participate in the construction of a ship block using the observation method. The results obtainedfrom this study are the estimated construction time of one ship block which is built in stages from marking,cutting, fitting, quality assurance, welding and grinding, to the final inspection by the Quality Controldepartment.
