Marine fuel bunkering is a key process in the shipping industry, involving the transfer of fuel from a storage facility to a vessel. While it is routine, bunkering requires strict attention to detail to prevent accidents, fuel contamination, and environmental harm. Implementing best practices ensures the process is safe, efficient, and compliant with international standards. Find here some essential practices to follow during marine fuel bunkering operations.

Conduct thorough pre-bunkering checks:

Before starting, all equipment involved in the bunkering process must be inspected for leaks, damage, or malfunctions. Verify that the fuel hoses, valves, and tanks are in proper working condition. Confirm that the receiving tank has sufficient capacity to avoid overfilling and ensure that proper documentation, including the bunker delivery note (BDN), is ready.

Implement a clear communication plan:

Establishing a clear communication channel between the vessel crew, bunker barge, and onshore personnel is vital. Use a common language and standard hand signals if required to ensure there is no ambiguity in instructions. Continuous communication during the operation helps address any issues quickly.

Perform a compatibility test:

To avoid contamination, conduct a fuel compatibility test if different grades or types of fuel are being mixed. Incompatible fuels can lead to sludge formation, clogging of filters, and damage to the engine. Testing beforehand ensures the fuel quality remains intact.

Monitor flow rates carefully:

Control the flow rate during the bunkering process to prevent spills or tank overpressure. Start with a slow flow during the initial transfer, gradually increasing to the desired rate. Regular monitoring helps detect anomalies early and prevents accidents.

Follow environmental regulations:

Adherence to local and international regulations, such as MARPOL Annex VI, is important during bunkering. Use spill containment equipment and have a response plan in place to handle leaks or spills. Ensure the use of low-sulphur fuel if operating in Emission Control Areas (ECAs).

Train personnel thoroughly:

Crew members involved in bunkering operations should be trained in safety procedures, fuel handling, and emergency protocols. Regular drills and refresher courses help maintain a high level of competence.

Complete post-bunkering procedures:

After the operation, inspect the bunkering equipment and vessel tanks for any leaks or damages. Collect and verify the BDN for accuracy, and test the fuel to ensure it meets the required specifications.
