GTT Receives Approvals for NEXT1 LNG System

GTT, a French engineering company specializing in liquefied natural gas storage, has received approvals from Bureau Veritas and Lloyd’s Register for its NEXT1 LNG cargo containment system. Bureau Veritas issued a Design Approval, while Lloyd’s Register issued a General Approval for Ship Service. These approvals, granted at the Posidonia 2024 marine exhibition in Athens, confirm that the technology complies with relevant rules and regulations, including the International Gas Carrier Code of the International Maritime Organization. With these approvals, GTT’s NEXT1 technology is now ready for commercial use.

The GTT NEXT1 technology aims to provide thermal performance equivalent to the Mark III Flex+ technology by using two metal barriers. The design incorporates prefabricated reinforced polyurethane foam panels to support the two membranes, offering a balance between thermal and mechanical performance. The second barrier is made of Invar, while the design of the first barrier is based on the existing corrugated stainless steel concept, similar to Mark Technologies. These design enhancements help achieve significant performance improvements while utilizing proven materials and components.

Chairman and CEO of GTT, Philippe Berterottière, expressed pride in the Bureau Veritas and Lloyd’s Register approvals for the GTT NEXT1 LNG cargo container system. He highlighted the company’s dedication to innovation and technological excellence in developing this advanced solution that blends proven technologies with new advancements to enhance performance and reliability in LNG transportation.
