ABS Awards AIP to DSME's FLNG Hull Design

ABS has issued Approval in Principle (AiP) for the design of a wide breadth, single row, near-shore LNG Floating Production Storage Offloading Vessel (FPSO) hull with a jetty-moored system developed by Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME).

The AiP is the completion of a joint development project (JDP) between DSME and ABS, combining the latest industry trends of shipbuilding practices and ABS rules to advance LNG FPSO safety standards.

The 64m wide barge-shaped hull features a GTT NO96 single row containment system with a storage capacity of 209,000 m3. It accommodates a jetty-moored system and approximately 40,000-metric tons of topside modules, which may produce 3.0~3.5 Million Tonnes 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 DSMEs sloshing research center in Korea. Through these extensive tests, DSME have verified that the new hull design and the membrane cargo containment system (CCS) can withstand the sloshing impact loads under actual operating conditions.

ABS has been a part of the FPSO industry since its earliest days and has played a key role in the development of the industry. The benefit from that involvement is that weve been able to both witness and participate in the evolution of FPSOs in size, complexity and technology. This project is the next step in th....
