Gaztransport & Technigaz (GTT) has secured an order from South Korea-based Hyundai Samho Heavy Industries for the tank design for two liquefied natural gas (LNG) carriers.

These contracts were awarded on behalf of a Middle-Eastern shipowner.

The tanks for the vessels will each have a capacity of 174,000m³.

Furthermore, the vessels will feature the Mark III Flex membrane containment system developed by GTT.

The Mark III technology is a cryogenic liner used for the containment of liquefied gas at low temperatures during shipping as well as onshore and offshore storage at atmospheric pressure.

Directly supported by the ship’s hull structure, the Mark III is a containment and insulation system.

The system features a primary corrugated stainless steel membrane, which is placed on top of prefabricated insulation panels.

It also uses a complete secondary membrane produced using composite material.

Designed for mass production techniques and easy assembly, the modular system features standard prefabricated components that can accommodate any tank shape and capacity.

The vessels are expected to be delivered in the second quarter of 2026.

At the start of the month, GTT won three orders from another South Korea-based company, Daewoo Shipbuilding & Marine Engineering (DSME), for the tank design for four new LNG carriers.

The contracts were awarded in Q4 2022 on behalf of various international shipowners. The vessels are anticipated to be delivered between the third and fourth quarters of 2026.
