Abstract:
The Inert gas system (IGS) is a critical component in supporting the operational safety of
tanker ships by preventing fires caused by flammable cargo vapors. This study aims to
analyze the effectiveness and common issues within the IGS, particularly on the MT.
Amarin Indah, and to formulate maintenance optimization strategies. Using a descriptive
qualitative method, data were collected through observation, interviews, and technical
documentation reviews. The findings indicate that disturbances in components such as
the scrubber, blower, and control valve frequently occur due to inadequate routine
maintenance, resulting in oxygen levels exceeding safe standards. Optimizing
maintenance, conducting regular inspections, and providing crew training are key
strategies to improve system reliability and ensure compliance with international safety
standards such as SOLAS and the ISM Code.
