OKPO, Korea – ABS has issued approval in principle (AiP) to Daewoo Shipbuilding & Marine Engineering (DSME) for two designs.
The first is for the design of a wide breadth, single row, near-shore LNG FPSO hull with a jetty-moored system. The AiP is the completion of a joint development project between DSME and ABS.
The 64-m (210-ft) wide barge-shaped hull features a GTT NO96 single row containment system with a storage capacity of 209,000 cu m (7.4 MMcf). It accommodates a jetty-moored system and about 40,000 metric tons (44,092 tons) of topsides modules, which may produce 3.0~3.5 MM metric tons per annum of LNG.
Due to wider breadth and different hull configuration compared to existing standard LNG carriers, various sloshing model tests have been carried out with the 6-DOF sloshing rig, driven by electric servomotors, at DSME’s sloshing research center in Korea. Through these extensive tests, DSME has verified that the new hull design and the membrane cargo containment system can withstand the sloshing impact loads under actual operating conditions, ABS said.
The second is for a floating storage power plant LNG cargo handling system. The system is designed as an all-in-one energy supply facility that can receive, store and regasify LNG, then generate and supply electricity and natural gas at the same time.
A new concept, DSME’s 200-MW design has the capacity to produce and supply electricity from floating structures with a length of 161 m (528 ft), width of 60 m (197 ft) and height of 33 m (108 ft), and directly supply natural gas of about 200 MMcf/d to an on land facility after storage and regasification.
The facility is expected to be used in countries lacking energy supply infrastructure and to support occasions where energy supplies are concentrated at certain times, such as the Olympic Games, international fairs and natural disasters, where demand peaks.
