BRITANNIA LOSS PREVENTION OCTOBER 2024 BUNKERING OPERATIONS ARE PIVOTAL IN MARITIME LOGISTICS AND PRESENT DISTINCT RISKS AND CHALLENGES. Each bunker operation is to be regarded as a unique event which possesses its own individual risks. Therefore, shipowners must conduct a comprehensive risk assessment of every bunker operation as part of their Safety Management System (SMS) before starting. Disputes arising from bunker quality are multifaceted, often hindered by insufficient evidence including representative samples and fuel analysis reports. The ISO 8217 specification may not adequately detect fuels with unusual compositions or contaminants until issues arise during usage. Possible issues may include, but are not limited to, blockage of fuel filters, overloading of purifiers, sticking of fuel injection pumps, broken piston rings, and ultimately, engine shutdowns. Even when fuel quality appears to meet specifications, further analysis may reveal unexpected contaminants, creating challenges to link them to engine damage. Furthermore, the global transition to low sulphur fuel has exacerbated the situation, leading to more variant blending for commercial reasons, which consequently may create quality inconsistencies. To mitigate the risk of fuel-related engine damage and downtime, and to strengthen evidence for potential bunker quality claims, adopting preventive measures and procedures is essential. Additionally, gaining an understanding of key legal principles surrounding bunker supply would be highly beneficial. BUNKERING PRECAUTIONS AND AVOIDANCE OF BUNKER QUALITY DISPUTES 2 | BRITANNIA LOSS PREVENTION | GUIDANCE RESOLVING A DISAGREEMENT ON QUALITY CAN PRESENT GREATER CHALLENGES AS COMPARED TO A QUANTITY DISPUTE. Identifying the actual root cause can be intricate and not readily discernible. Securing legal protection via contractual agreements becomes even more critical, alongside implementing appropriate operational precautions. OPERATIONAL CONSIDERATIONS Before initiating the bunkering operation, shipowners should verify and reasonably ensure compliance with the following: QUALITY DISPUTES • Compliance with Safety Management System (SMS): Adherence to the owner’s SMS procedures for bunkering, including the completion of thorough risk assessment prior to the operation. • Bunker plan: The ship should prepare a comprehensive bunker plan outlining key details such as the designated bunker tank(s), the order for filling these tanks, allocations for various fuel grades, recommended transfer rates, procedures for topping up, and the status of the fuel oil overflow tank (usually kept empty during bunkering). Whenever possible, take the new bunkers into empty tanks. Thoughtful and meticulous planning can help minimise risks associated with cross-contamination. • Bunker survey: If appointed, the surveyor should perform an independent investigation to identify the cause of any quality issues and discrepancies, if present. Additionally, they would also assist in the sampling and sealing process. • Recording & documentations: The ship should document all relevant/significant events during the bunkering operation, including start/stop times, flow rates and any unexpected stoppages. • Preparation, inspection, monitoring: Thoroughly plan for the preparation of the receiving bunker tank(s), prioritising tasks such as inter-tank transfers if operationally critical, before bunkering to ensure alignment with industry standards. Conduct careful inspecti
