ClassNK has granted Approval in Principle (AiP) for a 30,000 m³ LNG carrier designed by GTT, featuring two Mark III Flex membrane tanks. This innovative design eliminates conventional filling limits, enhancing operational flexibility. By utilizing a sophisticated ballast tank system, the vessel can maintain stability during ballasting operations, allowing for unrestricted cargo filling. This approval highlights ClassNK’s dedication to supporting technological advancements in the maritime industry while ensuring safety and regulatory compliance.
Approval for Innovative LNG Carrier Design
ClassNK has granted Approval in Principle (AiP) for a 30,000 m³ LNG carrier featuring two Mark III Flex membrane tanks developed by GTT. This approval confirms the vessel’s design concept, emphasizing enhanced operational flexibility through an innovative ballast tank design that eliminates traditional filling limits.
Enhanced Ballasting Operations for Stability
The unique ballast tank design, with upper and lower sections, improves stability during ballasting operations. By filling the upper tanks first, the vessel maintains a lower metacentric height, which reduces roll acceleration and sloshing loads. This advancement allows for unrestricted cargo filling levels, addressing challenges typically faced in LNG carriers and feeder transportation. ClassNK’s thorough design review ensured compliance with safety regulations, setting a precedent for future LNG carrier designs.
