Classification society DNV GL has awarded approval in principle to Kawasaki Heavy Industries (KHI) for a new non-spherical Moss tank.
KHI developed the independent Type-B tank for 180,000m³ vessels designed to sail through the expanded Panama Canal. The Japanese shipbuilder says the oval-shaped containment system design is as reliable as the spherical Moss tank but offers a 15 per cent increase in cargo capacity and has no filling restrictions.
The system can work with the Kawasaki panel system, KHI’s advanced heat-insulation system.
DNV GL issued the approval having tested the system for sloshing and buckling. Business director Johan Petter Tutturen described the project as “a long and enjoyable co-operation” with KHI.
