The orders have been placed by Chinese shipbuilder Yangzijiang Shipbuilding.
The 24,000 TEU-container vessels will have a fuel tank capacity of 18,600-cbm each.
They will be fitted with GTT’s membrane containment system, which the company says offers a “low and guaranteed Boil-Off Rate (BOR) for improved vessel operations.”
The vessels are scheduled to be delivered between the second quarter of 2026 and the first quarter of 2028.
Besides designing, GTT will assist in commissioning of the LNG tanks, first bunkering operation, maintenance, and LNG training for the crew. The company will also install maritime French technology company Ascenz Marorka’s technology on these vessels to monitor and improve performance to “further reduce their energy consumption and environmental footprint.”
LNG as marine fuel “reduces sulphur oxide emissions by 99%, fine particles by 91% and nitrous oxide emissions by 92%. It also reduces ship CO2 emissions by up to 25% compared to a conventional ship,” GTT says.
LNG can curb carbon dioxide emissions by about a quarter compared to conventional bunker fuels. But its methane emissions can be 36 times more potent as a greenhouse gas (GHG) compared to carbon dioxide over a century, according to a World Bank study.
