ABS and DSME developing LNG-fuelled drillships

03rd July 2014

ABS has entered into a joint development project (JDP) with South Korea's Daewoo Shipbuilding & Marine Engineering (DSME) to develop the industry's first LNG fueled drillship

The JDP will address challenges associated with storing and managing cryogenic LNG safely by combining DSME's experience developing and applying LNG technology to floating structures with ABS' technical standards and experience working on a number of gas-fuelled, LNG and regasification unit projects.

"This project builds on years of collaboration between ABS and DSME to evaluate innovative design concepts and new approaches that serve the needs of our clients and feature enhanced safety and efficiency standards," said Hoseong Lee, ABS vice-president, Global Korea Business Development and ABS Korea Energy Technology Center in Busan.

"DSME and ABS are recognised worldwide as leaders in technology research, shipbuilding, marine engineering and production of commercial vessels used in offshore operations," said DSME CTO and executive vice president Sung Geun Lee. "We are pleased to collaborate on this first-of-its-kind offshore structure leveraging our cutting-edge technologies and coupling these with ABS' experience validating new floating concepts."

To initiate the project, DSME has performed a concept design, comparison between two types of LNG storage tanks and analysis of the fuel gas supply system that will be installed on the drillship. ABS' scope of work calls for concept design review, basic engineering review and a risk assessment of the tank space and access area, fuel gas supply system, machinery space and access area and associated configurations.

ABS has provided approval in principle (AIP) to numerous floating concepts designed to produce oil or natural gas as well as the largest LNG carriers currently in service and has evaluated a host of gas-related marine projects based on the application of prescriptive requirements and advanced risk analysis to verify compliance with accepted safety standards. With safety and environmental efficiency playing a vital role in improving operational performance, ABS will continue to engage industry to develop and promote technical solutions that work to reduce emissions across the board.
