SYSTEM AND METHOD FOR TRANSFERRING CRYOGENIC FLUIDS

摘要

A SYSTEM (15) AND A METHOD FOR TRANSFERRING CRYOGENIC FLUIDS; E. G. TRANSFERRING LIQUEFIED NATURAL GAS (LNG) BETWEEN AN OFFSHORE RECEIVING/LOADING STATION (13) AND AN ONSHORE FACILITY (11). THE FLOWLINE SYSTEM (15) WHCH CAN BE SUBMERGED IN WATER IS COMPRISED OF A MAIN TRANSFER CONDUIT (20) WHICH IS POSITIONED WITHIN AN OUTER JACKET (21) AND A RETURN CONDUIT (23) WHICH IS POSITIONED WITHIN THE MAIN TRANSFER CONDUIT (20). THE ANNULUS (22) BETWEEN THE JACKET (21) AND THE MAIN CONDUIT (20) IS INSULATED. BOTH THE MAIN CONDUIT (20) AND THE RETURN CONDUIT (23) INCLUDE MEANS WHICH ALLOW THE RESPECTIVE CONDUITS (20, 23) TO EXPAND/CONTRACT WITH TEMPERATURE CHANGES.FIGURE 3
