Penerapan Failure Mode and Effect Analysis (FMEA) untuk Analisis Kegagalan Komponen Shiplift pada Galangan Kapal

Abstract

The shipbuilding industry is one of the key sectors contributing significantly to Indonesia’s economy. The shipyard company studied in this research is equipped with a shiplift, a type of lifting dock that plays a crucial role in enhancing the efficiency of the docking process. However, high usage intensity of the shiplift often leads to failures in various components, disrupting operations and causing time and cost losses for the company. To address this issue, this study applies the Failure Mode and Effect Analysis (FMEA) method to evaluate component failures within the shiplift system. It identifies failure modes and their impacts, and assesses risk levels using the Risk Priority Number (RPN) approach. Based on the FMEA analysis, 66 failure modes were identified across 39 components. The wooden dock component, with the failure mode of corroded support structure, recorded the highest RPN value of 64 due to its potential to cause structural collapse. In contrast, the lowest RPN value of 2.9 was found in the manometer component, related to a stuck needle. Maintenance prioritization should be focused on components with the highest RPN values. Furthermore, concentrating maintenance efforts on critical components identified through this analysis can effectively mitigate the risk of potential failures. The insights gained are expected to support the company in maintaining shiplift reliability and ensuring safe and efficient operations.
