ANALISIS KERETAKAN YANG TERJADI PADA CARGO MANIFOLD REDUCER SAAT PELAKSANAAN PROSES BONGKAR YANG TERJADI DI KAPAL GAS AMARIN JAYA

Abstract

Pratama, Tengku Dafa Randy. 2025. " Analysis of Cracking in Cargo Manifold Reducer During Unloading Process on Gas Amarin Jaya Ship” This research was motivated by the discovery of a crack in the cargo manifold reducer during the unloading process of propane on the LPG vessel Gas Amarin Jaya. The objective of this study is to identify the root causes of the failure and to propose effective problem-solving alternatives. A qualitative descriptive method was applied, using a Fishbone Diagram approach to map out the contributing factors. The findings reveal that the main causes of the crack were the excessive operational age of the reducer and the absence of a bottom support structure to bear the load during unloading operations. Additional contributing factors include the lack of a component runtime recording system, delayed spare part procurement, and the absence of a specific maintenance SOP for the reducer. Based on the analysis, the recommended solutions include the implementation of a preventive maintenance program based on operational hours and the design of a proper support system in accordance with maritime safety standards. The adoption of these measures is expected to reduce the risk of equipment failure and improve unloading efficiency.
