Abstract

A mooring and cargo transfer terminal is described, for use in transferring a fluid such as LNG (liquified natural gas) which is supercooled and therefore likely to cause severe icing of pipes and joints. The terminal includes a table support in the form of a tower extending from a base at the sea floor up to the sea surface, and a table device rotatable about a vertical axis at the top of the table support. The table device carries a pair of fenders that can press directly against the side of a ship, hawser couplings for tying the table device to a set of hawsers that hold it tightly against the ship, and one or more loading arms which can extend beyond the table device to connect to an LNG coupling on the ship. A pipe carries LNG from an underwater pipeline up to a fluid swivel at the top of the table support, and the rotatable portion of the fluid swivel connects to the loading arms to deliver the LNG thereto. The direct abutment of the rotatable table with the side of a ship near the bow thereof, enables loading arms of minimal length to be utilized to carry the LNG to the ship.
