SPM (Single Point Mooring) or SBM Operations

Single Point Mooring Operation

A Single Point Mooring Buoy consists of a buoy that is permanently moored to the seabed by means of multiple mooring lines/anchors/chains allowing cargo transfer of liquid petroleum products. The buoy contains a bearing system that allows a part of it to rotate around the moored geostatic part. When a Ship is moored to this rotating part of the buoy with a mooring connection, the vessel is able to freely weather-vane around the geostatic part of the buoy. Responsibility Master has the overall responsibility for the mooring operations of the vessel at the SBM.The officer-in-charge of … [Read more...]
