Indentifikasi Kerusakan Inert Gas Generator di MT. Petrosamudra

Abstract

Abstract: The Inert Gas Generator is an important auxiliary equipment in the operation of a ship during cargo loading and unloading processes. The Inert Gas Generator functions to reduce the oxygen content inside the cargo tanks. The safe oxygen content level in the cargo tanks is less than five percent, but in MT. Petrosamudra, the oxygen level exceeds five percent. This indication will be investigated with the research objective of determining the factors and impacts of inert gas generator damage on MT. Petrosamudra.

A qualitative method using the Fishbone diagram obtains information about the research site conditions. The causal diagram illustrates the relationship between the causes and their impacts. The cause-and-effect diagram, used in statistical process control, visualizes the factors that lead to problems originating from various elements. Based on the Fishbone diagram analysis, the major factors causing corrosion problems on the burner cone in the inert gas generator on the MT. Petrosamudra can be identified.

The research results indicate triggering factors for corrosion on the burner cone on MT. Petrosamudra includes leakage of seawater spray, limitations in spare parts, the use of inappropriate requisitioned materials, lack of periodic inspection and maintenance activities on the Inert Gas Generator (IGG). The impacts of corrosion involve the potential leakage of seawater spray, delayed repairs exacerbating damage, low effectiveness of protection due to a shortage of spare parts, easy damage and corrosiveness of the burner cone, risks to the safety of ship crew, failure of security systems, and instability of oxygen content in the ship's environment. This research is expected to provide a better understanding of this issue and identify solutions to improve efficiency and operational safety on the ship.
