GTT has received an orderfor the tank design of four new LNG carriers
The order from its Korean partner shipyards, Hyundai Heavy Industries and Hyundai Samho Heavy Industries, is for the tank design of four new LNGCs1.
Two of these LNGCs will be built by HHI and the two others will be built by HSHI on behalf of the same Asian ship-owner.
Order scope
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.
Mark III technology is a cryogenic liner used to contain liquefied gas at low temperatures during shipping, onshore and offshore storage at atmospheric pressure.
The Mark III membrane system is a containment and insulation system, directly supported by the ship’s hull structure. It is composed of a primary corrugated stainless steel membrane, positioned on top of prefabricated insulation panels, including a complete secondary membrane made of composite material.
Because it’s a modular system, it employs standard prefabricated components that can accommodate any shapes and capacities of tanks. They are designed for mass production techniques and easy assembly.
The technology and its evolutions equip more than 200 vessels in operation and under construction.
The new vessels will be delivered between the first and the fourth quarters of 2025.
GTT is a technological expert in containment systems with cryogenic membranes used to transport and store liquefied gases.
