GTT launches LNG Optim France’s GTT has launched LNG Optim, a new digital ‘Smart Shipping’ solution. This tool helps LNG operators, and LNG tankers or LNG-fuelled vessels, to prepare the voyages of their vessels in order to reduce the overall fuel consumption and to manage Boil-off gas in the tanks. For several years, GTT Group has been extending its range of services to support the maritime industry in its digital and energy transformation, with the launch of Smart Shipping solutions to optimize the energy performance of ships. The LNG Optim solution, based on GTT’s unique expertise in studying boil-off gas management and developed in collaboration with the Group’s subsidiaries, Ascenz, Marorka and OSE Engineering, has already been adopted by major players in LNG shipping. The studies performed by GTT to design this solution took into account the modelling of complex phenomena such as LNG ageing, the influence of sea states on Boil-off gas generation, as well as the impact of active systems like reliquefaction plants and subcoolers. Philippe Berterottière, Chairman and CEO of GTT, said, “This new technological innovation
from GTT, which is the result of joint work between the different teams of the Group, marks our ambition in the very promising field of “Smart Shipping”. Our Digital offer aims to support ship-owners, charterers and operators in the energy transition, by optimising the operational and environmental performance of their LNG-fuelled vessels.” Meanwhile, GTT has announced various orders for LNG tanks for LNG tankers building in various shipyards: • With South Korea’s Hyundai Heavy Industries (HHI) for the tank design of three new LNG tankers on behalf of an Asian ship-owner. As part of this order, GTT will provide the design and associated engineering services for the tanks of the vessels which will each offer a capacity of 174,000 m3. The LNG tanks will be fitted with the GTT Mark III Flex membrane containment system. Deliveries of the vessels are scheduled for the second and third quarters of 2024. • With South Korea’s Samsung Heavy Industries (SHI) for the tank design of three new LNG tankers on behalf of a shipowner whose name remains confidential at this stage. GTT will design the tanks of the vessels which will offer a cargo capacity 180,000 m3 and will be fitted with the Mark III Flex membrane containment system, a technology developed by

GTT. The vessels will be delivered between the second quarter of 2023 and the first quarter of 2024. • With China’s Jiangnan Shipyard (Group) for the cargo handling system and tank design of a LNG tanker on behalf of the Chinese shipowner JOVO. This is GTT’s first order for a membrane LNG tanker from Jiangnan, making the shipyard the second Chinese LNG tanker yard to construct a vessel with GTT technology. GTT will design the tanks of the vessel with a cargo capacity 79,800 m3. The vessel will be fitted with the GTT’s Mark III Flex membrane containment system and will be the first LNG tanker built in China to be fitted with the Mark III technology family. The vessel will be delivered in the fourth quarter of 2023. • With South Korea’s Hyundai Samho Heavy Industries (HSHI) for the tank design of two new LNG tankers on behalf of an European shipowner. GTT will design the tanks of the vessels, which will offer a cargo capacity 174,000 m3 and will be fitted with the Mark III Flex membrane containment system, a technology developed by GTT. The vessels will be delivered in the first quarter of 2024. GTT has also combined with China’s Hudong Zhonghua Shipbuilding Group (HZ), for a double Approval in Principle (AiP), from China
