South Korean shipbuilder Daewoo Shipbuilding & Marine Engineering (DSME) announced that it has launched the world’s first LNG carriers using a full re-liquefaction system that completely re-liquefies the evaporative gas generated from LNG carriers.
The natural gas re-liquefaction system is a technology that re-liquifies natural gas, which naturally vaporizes in the cargo hold during the operation of the LNG carrier, and puts it back into the cargo hold.
The company also delivered the world’s first LNG cargo ship with partial liquefaction system in 2016.
Nine LNG carriers ordered by DSME this year will all be equipped with a complete re-liquefaction system, which is expected to reduce operating costs for shipowners by about 8 billion annually, DSME claims.
The system can be applied to a carrier powered either by a high-speed ME-GI engine or by a low-speed X-DF dual-fuel engine, DSME added.
We have been intensive research and development since the early 2000s, and now we have the overwhelming LNG-related technology through the Energy System Experiment Center, which we built in 2015.
