Minor fuel spill during offshore transfer

The Marine Safety Forum has published a safety alert regarding a minor fuel spill during offshore fuel transfer. A platform supply vessel (PSV) was on location ready to deliver fuel, and the hose was connected. Crew were posted nearby on watch. The pump was started on a low rate in order to prove the line with the installation. Very shortly after starting the pump a spray of fuel was noticed from another fuel connection – not the one in use on this occasion. Bunkering operations were stopped immediately. Less than 1 litre of fuel was estimated to have escaped to sea.

This incident serves as a good reminder that all connections (not just the ones in use) should be checked before starting bulk transfer operations. All valves should be correctly closed with appropriate caps correctly fitted in place. Regular maintenance and inspection of manifold valves and connections are an important factor in preventing spills of this type.
