The reliability of pumping systems on tanker vessels plays a crucial role in ensuring safety, stability, and operational efficiency. The damage that occurred to Ballast Pump No. 2 on MT Infinity during the discharge process caused disruptions to vessel stability, trim correction accuracy, and overall operational efficiency, making accurate identification of the issue essential for preventing delays and greater operational risks. This study aims to identify the causes of the ballast pump failure, analyze its impacts on the discharge process, and determine the necessary corrective measures to prevent recurrence. The research was conducted through direct onboard observation, interviews with MT Infinity’s engineering officers and crew, and technical documentation obtained during sea practice. Data analysis employed a fishbone diagram to trace root causes based on human, method, machine, and material factors. The findings indicate that the failure was triggered by insufficient lubrication, worn-out ball bearings, damage to the mechanical seal and shaft, and misalignment between the motor and pump, all of which were exacerbated by improper maintenance procedures. By implementing consistent preventive maintenance, conducting proper risk assessments, and strengthening discipline within the Planned Maintenance System, the crew can minimize potential disruptions and ensure the discharge operation runs safely and efficiently.
Keywords: ballast pump failure, discharge operation, pump misalignment, mechanical seal damage, maintenance preventif.
