ANALISIS KEBOCORAN SALURAN PIPA PRESSURE/VACUUM VALVE (P/V VALVE) GUNA MENCEGAH PENURUNAN TEKANAN HOLD SPACE DI KAPAL GAS WALIO

Abstract

Alamsyah, Imam Bernando. 2025. “Analysis of Leakage in Vent Pipe of Pressure/Vacuum Valve (P/V Valve) to Prevent Pressure Drop in the Hold Space of Gas Carrier Walio”. Hold space is a critical area located between the ship's hull structure and cargo tanks, which must be maintained at specific pressure and oxygen levels to prevent fire hazards and structural damage to the tanks. During operations, a case of hold space pressure drop was identified, caused by a leakage in the P/V valve pipeline. This research was conducted using a qualitative method based on direct observation during sea practice aboard the Gas Walio vessel, supported by technical documentation and literature studies. The findings reveal that the main contributing factors to the issue are pipe corrosion, lack of routine inspections, and poorly implemented planned maintenance system (PMS). The author recommends regular inspections of the P/V valve pipeline, the use of inspection checklists in accordance with ISM code standards, prioritization of critical equipment maintenance, and supervision during maintenance activities. The implementation of these strategies is expected to effectively prevent pressure drops in the hold space and enhance overall vessel safety.
