Samsung Heavy Industries (SHI) has been awarded the Approval In Principle (AIP) by ABS for the X-Reli LNG Boil Off Gas Expander which is the part of the Expansion Re-Liquefaction System of SHI.
SHI says that the X-Reli System is made for the application of low and medium pressure. According to SHI, this will provide improved efficiency and reliability in comparison to the present high pressure re-liquefaction systems.
“Re-liquefaction is a useful capability for owners and operators, offering increased flexibility and the potential to maximize 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,” said Eric Kleess, ABS Senior Vice President, Eastern Hemisphere Operations.
The system uses expansion technology which raises the re-liquefaction capacity. This will help the generated boil off gas from the cargo tank except the fuel gas that is for generator engines to be liquefied. X-Reli by SHI will fulfill the requirement of the industry for energy efficiency and better environmental performance.
“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,” said SHI Ship & Offshore Research Institute Vice President, Dr. Yong Lae Shim. “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 has also checked if the design of the re-liquefaction system is suitable and feasible so as to confirm that the system is in compliance with the present Rules of ABS.
