GTT has received an order from its long-standing partner, HD Hyundai Heavy Industries, to design cryogenic fuel tanks for 12 new LNG-powered container vessels commissioned by a European shipowner. The order was placed in the first quarter of 2025.
These vessels will be equipped with LNG fuel tanks of 12,750 m³ capacity, featuring GTT’s Mark III Flex membrane containment system. Additionally, they will incorporate the “1 barg” design, which allows an operational pressure of up to 1 barg instead of the standard 0.7 barg. This marks the second series of vessels utilizing this advanced design, aligning with future port regulations that require ships to connect to shoreside electrical power while at berth.
This order underscores the strong collaboration between GTT and its partners, reflecting a shared commitment to leveraging LNG as a key solution in the maritime industry’s energy transition. LNG as a marine fuel significantly reduces emissions of nitrogen oxides, sulfur oxides, CO₂, and fine particulates. GTT estimates that LNG propulsion can cut CO₂ emissions by approximately 25,000 tons per year per vessel compared to conventional heavy fuel oil.
The 12 container ships are scheduled for delivery between the second quarter of 2027 and the fourth quarter of 2028.
Philippe Berterottière, Chairman and CEO of GTT, stated: “GTT is proud to place its innovation at the service of its customers and to support them in the energy transition of maritime transport. The Mark III Flex containment system and the “1 barg” concept, which is being applied here for the second time, offer concrete solutions for optimising LNG propulsion and anticipate regulatory changes. This new order demonstrates our partners’ confidence in our expertise and its commitment to more sustainable shipping.”
