OFFSHORE TRANSFER TOWER WITH A CARDANIC COUPLING SYSTEM FOR A LNG STORAGE TANKER

Floating storage facilities for liquid hydrocarbons produced offshore have progressed from the conceptual stage to practical technological designs. The problems of mooring such structures with the aid of special buoy systems have been largely solved particularly for the case where the liquid to be stored is at ambient temperature and when the connection between the seabed and the mooring buoy can be realised with flexible hoses. For storage afloat of low-temperature liquids, e.g. LNG, the connection between the subsea flowline and the mooring buoy poses a number of special engineering problems. The solution here described is an articulated offshore transfer tower carrying the LNG lines which are insulated from the ambient marine environment. The tower also serves as a mooring point for the floating storage system and the connection between the two units is achieved by a rigid bridge. Model tests have been performed in a wave-tank and the results show that the concept is feasible under extreme sea- and weather conditions.
