DSME's New LNG Tank Technology Approved by LR

Press Release
Wednesday, May 30, 2012

ACTIB ((Aluminium Cargo Tank Independent Type B) tanks - prismatic, large, independent cargo tanks -  reduce sloshing, suitable for LNG containment

The ACTIB tanks, constructed of insulated aluminium 5083, will have the world’s largest storage capacity in an independent, insulated LNG tank system. The volume capacity in the initial design will be nearly three times larger than comparable types currently in operation.

Lloyd’s Register has approved new prismatic IMO Type B independent cargo tanks, so called ACTIB (Aluminium Cargo Tank Independent Type B). The initial approval is for use in a DSME-developed 210,000 m3  STD LNG-RV design in accordance with LR’s Guidance notes for liquefied gas carriers and floating offshore installations adopting IMO Type B independent tanks primarily constructed of plane surfaces.

The approval in principal (AiP) follows a one year period of development and collaboration between DSME and Lloyd’s Register. An evaluation for the next step - General Approval - has also been completed by Lloyd’s Register.

One of the leading benefits of ACTIB is the potential for safe and more flexible operations in part filled conditions as the structural arrangement can be designed to withstand sloshing. So, as well as application in the DSME designed 210,000 m3 volume LNG carrier, the tank will be of particular interest for wider use in LNG shuttle tankers, LNG FPSOs as well as LNG-as-fuel tanks where partial fill is a critical operational issue.

Through continued collaboration, Lloyd’s Register and DSME become aware of the importance of further technical issues requiring examination, such as sloshing and fatigue calculations, and which are dealt with in the Particular Ship Application Approval (PSApp) stage, which takes place, typically, once a newbuilding contract has been signed.

DSME also plans to apply the ACTIB system to the fuel tank design of LNG-fuelled ships such as DSME’s next-generation ‘green ship’ powered by LNG.
