A Single-Point Mooring (SPM) system for floating LNG plants developed by Imodco Inc. and General Dynamics Corp. specifically for an offshore California site, is self-contained and self-sufficient with complete crew accomodations. The floating terminal would be equipped with the full system required to load or unload an LNG tanker, store the LNG, liquefy or regasify it, and receive or send it by a seabed pipeline to shore. The IMODCO SPM terminal is designed to moor permanently the floating LNG barge in all weather conditions by means of a mooring yoke which attaches the barge to an articulated tower. The tower is a buoyant structure connected to piled mooring based on the seabed by a universal joint. This permits the tower to rotate in any direction about the joint. Design studies indicate that the system, with the storage-regasification barge designed by General Dynamics, will withstand 100 yr storm conditions. More design details are given including the barge and tanker characteristics, maximum operating and storm (survival) conditions, and vaporized LNG operating data (40/sup 0/F, 1800 psi normal operating pressure).
