- DNV GL approves DSME’s Solidus LNG cargo containment system in vessels.
- The GASA approval for installation of technology shows faith in DSME’s high-performance insulation.
- Together they are trying to optimize and develop technology that ensures safety and efficiency of ships.
- 3D model hull approval, estimating the allowable wave heights, structural safety assessments are on the loop.
South Korea’s Daewoo Shipbuilding & Marine Engineering (DSME) has received general approval for ship application from class society DNV GL for its Solidus LNG cargo containment system in vessels, writes John Synder for an article published in LNG World Shipping.
What is GASA?
A general approval for ship application (GASA) is full approval of the technology under DNV GL rules for classification, that examines a typical installation of the technology in a vessel.
“DNV GL’s approval of Solidus is a great milestone for DSME, marking our leadership in LNG technology”, said DSME president and chief executive Sung-Geun Lee.
“The Solidus design improves the newbuilding productivity and significantly reduces costs, making it a big step forward in developing the LNG carrier industry for shipbuilders and suppliers.”
Solidus is based on DSME’s extensive experience in building LNG carriers and uses a high-performance insulation material developed in co-operation with Germany’s BASF to lower LNG boil-off rates.
To optimise the safety of the system and prevent LNG leakage, the Solidus LNG cargo containment system also incorporates two metallic barriers around the high-performance insulation.
Agreement for safety and efficiency
The GASA follows a framework agreement between DNV GL and DSME to co-operate on projects to develop advanced technologies to maximise the safety and efficiency of ships and offshore units.
The two organisations plan joint studies regarding 3D model hull approval, estimating the allowable wave heights for a 174,000- m3 LNG FSRU, and a structural safety assessment for the Solidus LNG cargo containment system.
DNV GL group president and chief executive Remi Eriksen said the agreement extended the technical partnership that has been in place for decades.
