DEVELOPMENT OF MARINE OIL TERMINAL EQUIPMENT

Safety considerations must provide for structural integrity of the loading arm, for unexpected failure of power or control systems, and for emergency disconnection (stopping flow, shutting walves, and draining and stowing the loading arm). With quick-connect couplings and automatic sequential controls, the complex disconnect procedure can be triggered by a single "panic-button" in time of emergency. However, quick-connect couplings are heavy and expensive (without offsetting labor saving) and the claw-type couplings can crush the cast iron manifold flanges carried by 30% of the world's tanker fleet. A new type of LNG swivel joint developed by Woodfield Rochester Ltd. for LNG loading arms uses a journal bearing lined with reinforced PTFE (polytetrafluoroethylene). Woodfield also has cooperated in developing a new single point mooring (SPM) buoy having a fixed length anchor chain and underbuoy hoses of fixed length. Further development is under way to obviate all need for rubber floating and underbuoy hoses and to allow LNG to be handled through an SPM system.
