Classification society Bureau Veritas is days away from granting general design approval to Braemar Engineering’s FSP containment system, executives attending London International Shipping Week (LISW) heard today.
Braemar Engineering is developing its Type B containment system in China, having taken over the design licence from General Dynamics, teaming up with aluminium fabrication specialist Shanghai Aerospace to build and test the prototype tank.
“Once we get this approval, Braemar hopes to start to market the FSP tank solidly in the near term,” Braemar Technical Services managing director EMEA Andy Bright told an LISW seminar on LNG.
Mr Bright sees a market for the FSP design in small to medium-sized LNG carrier newbuildings, and for retrofitting older tonnage.
Nearly a decade in development, the flat panel semi-membrane prismatic (FSP) design falls between Type A and Type B containment systems but is designated Type B. In 2015, Braemar formed a joint venture with the Honghua Group, EnTX and Jamestown Marine Metals to develop and market the FSP LNG containment system.
The system uses flat plates to tackle problems linked to partial filling and sloshing loads in LNG tanks. It features an external, mild steel exoskeleton welded to the vessel’s hull that holds the self-supporting aluminium tanks in place, removing the need for internal structure.
Lloyd’s Register granted approval in principle for the design in 2009. Last year, ABS awarded approval in principle to the FSP design.
