DSME Builds World’s First LNG Carrier Equipped with FRS for Low-pressure Engine

Daewoo Shipbuilding & Marine Engineering (DSME)’s LNG carrier with full re-liquefaction system (FRS) for low-pressure engine

Daewoo Shipbuilding & Marine Engineering  ( DSME ) has sharpened its competitive edge by successfully applying a full re-liquefaction system (FRS) to vessel powereed by a low-pressure engine, following its successful application of the system to a vessel powered by a high-pressure engine.

On August 16, DSME said that it has built the world’s first liquified natural gas (LNG) carrier running on a low-pressure engine that is equipped with an FRS, which re-liquidates 100% of the evaporating gas generated by the LNG carrier. The vessel was delivered to its client, Japanese vessel company MOL.

The LNG re-liquefaction system (FRS) re-liquidates the natural gas evaporating from the cargo hold during the operation of the LNG carrier and puts it back to the cargo hold. It is a new technology that increases the efficiency of an LNG carrier.

The “MRS®-F,” which was adopted this time, is a technology developed for LNG carriers with a low-pressure engine, and it maximized the re-liquefaction effect of the evaporating gas by combining the methane refrigerant system to the existing FRS.

Especially, during the test performed before the vessel transfer, MRS®-F exceeded the daily evaporation rate (the loss amount of natural evaporation of LNG carrier during the operation) standard that a shipyard generally guarantees in the contract. It is expected that the vessel holder will be able to save about 10 billion won (US$9 million) worth of LNG loss per year through this system.
