DNV GL awards Kawasaki Heavy Industries AiP for new non-spherical (MOSS) LNG tank
DNV GL has awarded Kawasaki Heavy Industries, Ltd (KHI) an Approval in Principle (AiP) for their newly developed non-spherical (MOSS) tank. The new tank is a IMO Independent Type B LNG tank that has been developed for use in 180KM3 LNG carriers designed to pass through the new Panama Canal, the company said in its press release.
KHI says that the new tank has the same reliability as a spherical (MOSS) tank, but has an increased cargo capacity of 15 per cent. It can also be used with the “Kawasaki Panel System”, an advanced heat insulation system developed by KHI. DNV GL carried out comprehensive sloshing and buckling analyses together with KHI, which demonstrated that the new tank provided an equivalent level of safety performance to the well-known spherical (MOSS) tank with no filling restrictions.
An Approval in Principle is an independent assessment of a concept within an agreed framework, confirming that the design is feasible and no significant obstacles exist to prevent the concept from being realized. The AiP is typically carried out at an early stage of a project to confirm its feasibility for the project team itself, company management, external investors or regulators.
