New GTT tanks could facilitate switch from LNG to NH3
French LNG engineering group GTT said July 19 it had secured an order for the fuel tank design for LNG-fuelled container vessels that can facilitate a possible conversion to ammonia fuel.
GTT secured the order from Samsung Heavy Industries to design fuel tanks for five very-large LNG-fuelled containerships, each with the carrying capacity of 15,000 containers. The order was made on behalf of ship-owner Seaspan.

“The fuel tank of each vessel will offer a capacity of 12,000 m3 and will be fitted with the Mark III membrane containment system,” GTT said. “These tanks will include unique features to facilitate a potential conversion of these vessels to ammonia.”
Vessels will be chartered to Israel's ZIM. Vessel delivery is expected from Q3 2023 to Q1 2024.
“ZIM as charterer is striving for zero environmental impact in our operations, with special focus on alternative non-polluting fuel use,” ZIM’s COO David Arbel said.
As a compound of nitrogen and hydrogen, raw ammonia yields no carbon emissions.
GTT has been busy with new orders catering to the energy transition. It was hired in May to design cryogenic fuel tanks for 12 LNG-fuelled containerships due to be built for shipping group CMA CGM.
CMA CGM is looking to have a fleet of 44 LNG-fuelled containerships in operation by 2024, as part of efforts to tackle its emissions.
