OPTIMALISASI PERAWATAN INERT GAS SYSTEM (IGS) GUNA MENUNJANG KESELAMATAN KERJA DI MT. GRIYA CIREBON PADA SAAT KEGIATAN BONGKAR

Abstract

This study discusses the optimization of Inert Gas System (IGS) maintenance as an effort to support occupational safety during cargo discharging operations on board MT. Griya Cirebon. The IGS is an essential safety system on tanker vessels that functions to reduce oxygen levels inside cargo tanks in order to prevent the risk of fire and explosion in accordance with the provisions of SOLAS 1974 and IMO standards. The research problem arose when disturbances occurred in several IGS components, namely the inert gas fan which did not operate optimally and the deck water seal water level which was below the normal limit, causing delays in cargo discharging operations and potentially creating explosion hazards. These conditions indicate that maintenance practices, inspections, and the deck crew’s understanding of IGS operational procedures still need improvement. This research employed a qualitative method using a case study approach and fishbone analysis to identify the factors causing disruptions in the IGS from the aspects of human resources, methods, equipment, and maintenance. The results of this study are expected to provide practical solutions for improving the effectiveness of IGS

maintenance and supporting the implementation of safe, efficient, and procedure- compliant cargo discharging operations on board.
