Daewoo Shipbuilding and Marine Engineering (DSME) has unveiled what it calls a “unique” LNG cargo containment system.
The company said the aluminium cargo tank – independent type B (ACT-IB) – has the largest storage capacity of any other ship containment system.
The technology involved in the system will be applied to the company’s LNG-FPSOs and LNG carriers, it said.
DSME said the ACT-IB can contain a maximum of 210,00m3 of LNG, which is a threefold increase, with a conventional containment system of about 80,0003.
The containment system allows easy integration into LNG carriers or floating facilities and enables the company to save a significant amount of royalty fees currently paid to the French or Japanese LNG containment systems.
The tank has successfully completed a test programme, which includes thermal stress analysis, fatigue analysis and crack growth analysis, the company said.
DSME said it will apply the system to its new generation of green ship technologies, including LNG-fuelled ships.
