ABS and DSME to develop LNG fuelled drillship

Published by
LNG Industry,

ABS and Daewoo Shipbuilding & Marine Engineering (DSME) have entered into a joint development project (JDP) for the industry’s first LNG fuelled drillship.

The JDP will address challenges associated with storing and managing 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.

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.

Dr Hoseong Lee, ABS Vice President, Global Korea Business Development and ABS Korea Energy Technology Center in Busan, said: “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.

“We are targeting the Gulf of Mexico as a key market for an LNG fuelled drillship where, given the abundance of affordable shale gas resources in the US, LNG as a marine fuel makes good economic sense.”

ABS Executive Vice President, Energy Development, Ken Richardson, added: “Many North American vessel owners and operators are making the switch to LNG to achieve substantial operating savings by reducing fuel consumption and lowering emissions to meet the strict sulfur requirements in the North American Emissions Control Area […] ABS already has taken the critical first step to develop guidance that addresses the first application of LNG technology on US flagged support vessels for Gulf of Mexico operations. An LNG fuelled drillship is another groundbreaking concept that illustrates how deepwater applications are evolving.”
