Classification society DNV GL presented Daewoo Shipbuilding & Marine Engineering (DSME) with a general approval for ship application (GASA) for DSME’s SOLIDUS LNG cargo containment system.

DSME and DNV GL also have signed a framework agreement for cooperation on joint development projects (JDPs) for future technologies in the shipbuilding and offshore plant industries.

The agreement confirms the cooperation of DSME and DNV GL through future JDPs to develop advanced technologies to maximize the safety and efficiency of ships and offshore units, DNV GL said in a statement.

Planned joint studies include 3D model hull approval, the estimation of allowable wave heights for a 174,000 LNG FSRU, and a structural safety assessment for SOLIDUS which is an LNG cargo containment system developed by DSME.

“Through the JDPs with DNV GL, we aim to develop new technologies to meet the needs of our clients and further provide the direction in the shipbuilding and offshore industries,” DSME president and CEO Sung-Geun Lee said.

The agreement is an extension of the technical partnership that has been in place for decades, added DNV GL Group president and CEO Remi Eriksen.

SOLIDUS is the result of DSME’s extensive experience with LNG carrier newbuildings and uses a high-performance and environmentally friendly insulation material developed with BASF, to lower LNG boil-off rates, the statement reads.

In addition, to optimize the safety of the system and prevent LNG leakage, DSME has incorporated two metallic barriers into SOLIDUS.

Sung-Geun Lee added that discussions are already underway for a new vessel using the system.
