Repair, Fault Tree Analysis, Probability


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