Bunkering tanker

A bunkering tanker is a small tanker that delivers marine fuel, heavy fuel oil, marine gas oil, or increasingly LNG and methanol, to ships at anchor or alongside in port and at offshore bunkering zones. It carries multiple coated or heated tanks, metering systems, and a flexible delivery hose for ship-to-ship transfer. Sizes run from a few hundred to several thousand dwt, sized to the port and the receiving ship. The bunker barge or tanker is the last link in the marine fuel supply chain, taking product from a shore terminal and pumping it into a receiving vessel’s bunker tanks against a measured bunker delivery note.
