FRENCH engineering company GTT has received an order from the Chinese shipyard Yangzijiang, to design the cryogenic fuel tanks of 10 ultra-large container vessels fuelled with Liquefied Natural Gas (LNG), reports New York's Marine Link.
"Used as a marine fuel, LNG is today the best available industrial tool to preserve air quality, a major public health issue. It reduces sulphur oxide emissions by 99 per cent, fine particles by 91 per cent, and nitrous oxide emissions by 92 per cent. It also reduces ship CO2 emissions by up to 25 per cent compared to a conventional ship," said GTT.
A fleet of 10 container vessels, each of 24,000 TEU, will be equipped with a single LNG fuel tank, boasting an impressive capacity of 18,600 m3.
To ensure enhanced vessel operations, the tanks will be integrated with the cutting-edge Mark III membrane containment technology, a creation of GTT, which guarantees a low Boil-Off Rate (BOR) for optimized efficiency.
The delivery of these vessels is scheduled to take place between the second quarter of 2026 and the first quarter of 2028.
GTT is not only providing engineering services and technical support to the shipyard but is also actively assisting the operator at every stage of their LNG-fuelled project.
From commissioning the LNG tank to facilitating the first LNG bunkering operations and managing ongoing operations and maintenance, GTT is offering comprehensive support.
Furthermore, GTT is offering specialized LNG training for the crews, supported by its advanced G-Sim training simulator, which replicates future LNG operations on the vessels.
Additionally the company provides its HEARS emergency response service, offering 24/7 technical assistance.
To further optimize the operational performance of these 10 vessels and reduce their energy consumption and environmental impact, GTT is equipping them with Ascenz Marorka1 digital solutions, enabling real-time monitoring and optimization.
