analisi penyebab kerusakan safety device pada incinerator di kapal lng/c sm.golden eagle

Abstract

This study aims to analyze the causes of safety device failure in the incinerator on board LNG/C SM. Golden Eagle. The problems discussed in this research include damage to the trap door system, damage to the refractory wall, and the influence of operation and maintenance on the reliability of the incinerator safety system. This research applied a descriptive qualitative method, with data collected through direct observation during sea practice, interviews with engine officers, and documentation such as the instruction manual book, engine log book, Planned Maintenance System (PMS), and photographs of the equipment condition. The results show that the failure of the incinerator safety device was caused by the accumulation of plastic waste residue on the trap door, which made the trap door stuck and caused a flashback fire when it was opened. In addition, excessive burning of plastic waste and insufficient maintenance caused damage to the refractory wall in the form of cracks and holes. This condition may lead to heat leakage and increase the risk of fire in the engine room. The appropriate efforts to overcome these problems include carrying out routine maintenance according to the instruction manual book and PMS, cleaning the trap door and combustion chamber regularly, controlling the amount of plastic waste burned, and ensuring that all safety devices function properly. By implementing these measures, the reliability and safety of incinerator operation on board can be improved.
