Abstract

A boom is described for use on a single point mooring system to connect a tower thereof to tankers or other vessels, wherein the boom is constructed to enable rapid attachment to a vessel and to protect boom components when not connected to a vessel. The boom has an inner end pivotally connected about a horizontal axis to a transfer structure, and has an outer end forming a compressible structure which can withstand compression and tension loads during coupling to a vessel. The boom end can be pulled up along the bow of a vessel until a secure connection can be made to the vessel, at a level at which a pipe connection at the end of the boom can connect to a pipe connector on the vessel. A buoyancy tank connected by a strut to an outer end portion of the boom holds the outer end of the boom at a considerable height above the water. Tanks lie on either side of the pivot axis of the boom, and a pump can be utilized to transfer water from one tank to the other to raise or lower the boom.
