ABS awards AiP to SHI for X-Reli LNG Boil Off Gas Expander

LNG Industry,

ABS has announced that it has awarded approval in principle (AiP) to Samsung Heavy Industries (SHI) for its innovative X-Reli LNG Boil Off Gas Expander – part of SHI’s Expansion Re-Liquefaction System.

According to the statement, the X-Reli system is optimised for low and medium pressure application. SHI claims that this offers increased efficiency and reliability compared to existing high pressure re-liquefaction systems.

Eric Kleess, ABS Senior Vice President, Eastern Hemisphere Operations, said: “Re-liquefaction is a useful capability for owners and operators, offering increased flexibility and the potential to maximise cargo delivery. The ability to operate this at low or medium pressure reduces barriers to adoption of the technology and ABS is proud to be able to facilitate this.”

The system increases re-liquefaction capacity using expansion technology. This allows the generated boil-off gas (BOG) from the cargo tank, except the fuel gas for generator engines, to be re-liquefied. According to the statement, X-Reli has been designed to address industry requirements for energy efficiency and improved environmental performance.

SHI Ship & Offshore Research Institute Vice President, Dr. Yong Lae Shim, said: “By gaining the ABS AIP Certificate for the X-Reli System, SHI has secured approval of its competitive re-liquefaction solution, which has been developed to meet the various needs of ship owners.

“The X-Reli system will be tightly integrated with SHI's smart ship solution SVESSEL® - SVESSEL Onboard and SVESSEL Onshore - to assure quality and performance. It will become one of SHI’s core technologies for LNG carriers, alongside its LNG cargo tank technology.”

ABS claims that it has reviewed the suitability and feasibility of the re-liquefaction system designed to confirm the system would comply with current ABS rules.
