GTT, the technology expert in membrane containment systems used to transport and store liquefied gases, has obtained a Design Approval (DA) from the classification society Bureau Veritas and a General Approval for Ship Application (GASA) from Lloyd’s Register for its GTT NEXT1 LNG cargo containment system, according to an article published on their website.
About the approvals
These two approvals, officially granted at the Posidonia 2024 maritime show in Athens, mark a major milestone for GTT NEXT1 technology. Through them, Bureau Veritas and Lloyd’s Register confirm that the technology complies with all applicable rules and regulations, including the International Maritime Organization’s International Gas Carrier Code (IMO IGC Code). With these two approvals, GTT NEXT1 technology is now ready for commercial deployment.
GTT NEXT1 technology aims to offer a thermal level of performance equivalent to that of Mark III Flex+ technology1 while using two metallic barriers. The use of prefabricated reinforced polyurethane foam panels to support the two membranes provides the best compromise between thermal and mechanical performance. The secondary barrier is made of Invar, and the design of the first barrier is based on the existing corrugated stainless steel concept, similar to that of the Mark technologies. By activating these design levers, it is possible to deliver significant performance improvements, while using proven materials and components.
