DSME presents in-house developed LNG containment systems
South Korean shipbuilder, DSME held a demonstration of its self-developed LNG cargo containment systems ‘Solidus’ and ‘Mctib’, and an indirect glycol water type re-gasification system at its Energy System Research Center in Geoje shipyard.
More than 80 representatives from a group of ship owners, oil companies and class societies attended the demonstration and observed the ‘Solidus’ & ‘Mctib’ real mock-up tanks and re-gasified LNG processing by the indirect re-gasification system.
DSME LNG re-gasification system applied indirect glycol water heating type vaporizer based on results of various tests using LNG and it is expected to lift competitiveness of DSME’s LNG-FSRU by saving its initial and operating costs.
BW Gas contracted the world’s first FSRU with this technology and the ship is scheduled to be delivered to BW group in 2019, DSME said in a statement.
Solidus is a membrane type cargo containment system, which maximizes safety of the containment system by adopting two metallic barriers and insulation material that has been developed in cooperation with BASF. Solidus boasts a daily LNG boil-off rate (BOR) of 0.049 percent, which is 30 percent higher performance compared to the currently lowest level of 0.07 percent. This means that a 170,000 cubic meter LNG carrier can transport its cargoes more efficiently and can deliver more LNG annually.
DSME claims that its total LNG cargo that can be saved by using the Solidus system is estimated to be worth about $11.25 million during 25-year operation.
The shipbuilder developed the Mctib, an independent IMO Type-B Tank that uses high manganese steel jointly with POSCO. It has high impact-strength and can optimize space in comparison with the other independent tanks of type-B. It also reduces the material cost significantly, enhancing its cost competitiveness.
