ABS approves SHI’s LNG boil-off technology

Classification society ABS has awarded approval in principle (AIP) to Samsung Heavy Industries (SHI) for its X-Reli LNG boil-off gas expander, a part of SHI’s expansion re-liquefaction system.

According to SHI, the X-Reli system is optimized for low and medium pressure application, which SHI company says offers increased efficiency and reliability over existing high-pressure re-liquefaction systems.

The system increases re-liquefaction capacity using expansion technology, which enables the generated boil-off gas from the cargo tank, except the fuel gas for generator engines, to be re-liquefied. SHI has designed X-Reli to address industry needs for energy efficiency and improved environmental performance.

SHI Ship & Offshore Research Institute VP Yong Lae Shim added: “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 to assure quality and performance. It will become one of SHI’s core technologies for LNG carriers, alongside its LNG cargo tank technology.“
