GTT Secures Multiple LNG Tank Design Orders from HD KSOE and Hanwha Ocean

## GTT Wins Multiple LNG Carrier Tank Design Orders from South Korean Shipyards Gaztransport & Technigaz (GTT), the French specialist in cryogenic membrane containment systems, has secured a new batch of tank design orders for liquefied natural gas carriers (LNGCs), according to Offshore Energy. The contracts have been awarded by two of South Korea's premier shipbuilding groups: HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and Hanwha Ocean. The awards further cement GTT's position as the leading provider of LNG containment technology, with its proprietary membrane systems — including the widely adopted Mark III and NO96 series — specified across the vast majority of LNG carriers built at major global yards. ### Strategic Significance The dual-yard nature of these orders is notable. HD KSOE, the holding entity overseeing HD Hyundai Heavy Industries, HD Hyundai Mipo, and HD Hyundai Samho, and Hanwha Ocean — formerly DSME — together represent a substantial share of global LNG carrier orderbook capacity. Continued design mandates from both groups underscores the sustained demand for new LNG tonnage as energy markets worldwide maintain their reliance on liquefied natural gas as a transition fuel. Global LNG trade has remained robust, driven by ongoing European diversification away from pipeline gas and strong demand growth across Asian markets. This sustained appetite for LNG has translated into a healthy newbuilding pipeline, with shipyards in South Korea and China competing for a growing volume of LNGC orders. GTT's tank design fees, while individually modest relative to vessel construction costs, accumulate significantly across a large orderbook and provide the company with a recurring, high-margin revenue stream tied directly to LNG shipping market activity. ### Market Context The LNG carrier fleet is undergoing a generational expansion, with vessels increasingly specified at larger capacities — typically 174,000 cubic metres — and equipped with advanced propulsion systems designed to minimise boil-off gas losses. GTT's containment solutions are integral to these designs, and the company has also been active in developing technology for LNG as a marine fuel, including tank systems for LNG-powered vessels beyond dedicated carriers. Further details on the number of vessels covered under the latest design orders and their scheduled delivery windows were not disclosed at the time of reporting.
