Six LNG Vessels to Sport GTT’s Tank Design

Why It Matters

The contracts cement GTT’s position as the leading containment‑system supplier, supporting the surge in ultra‑large LNG carrier construction and reinforcing global LNG trade infrastructure.

Key Takeaways

• GTT designs tanks for six new LNG carriers
• Four vessels 175,000 m³ for Shandong Marine Energy
• Two vessels 174,000 m³ for Samsung Heavy Industries
• All use GTT’s Mark III Flex membrane system
• Deliveries scheduled between Q3 2028 and Q1 2029

Pulse Analysis

The liquefied natural gas (LNG) shipping sector is entering a new growth phase, driven by rising demand for cleaner energy and the need to transport larger volumes across longer distances. Ultra‑large carriers, typically exceeding 170,000 cubic metres, offer economies of scale that lower per‑tonne transport costs, making them attractive to buyers and charterers alike. As major importers expand their regasification capacity, shipyards worldwide are racing to deliver these high‑capacity vessels, creating a fertile market for specialized technology providers.

GTT’s recent orders for six carriers highlight the firm’s strategic advantage in membrane containment technology. The Mark III Flex system, a flexible, lightweight membrane that accommodates thermal expansion, delivers higher cargo capacity and reduced boil‑off rates compared with traditional spherical tanks. By standardising on this design for both Chinese and South Korean shipyards, GTT streamlines engineering, shortens construction timelines, and offers ship owners a proven solution that mitigates operational risk. The contracts also diversify GTT’s client base, reducing reliance on any single shipyard and reinforcing its global supply chain resilience.

Industry observers see these deals as a bellwether for the broader LNG market. With the European Union and Asian economies committing to net‑zero targets, demand for LNG as a transition fuel is expected to stay robust through the 2030s. Consequently, shipbuilders are scaling up production capacity, and containment‑system innovators like GTT will play a pivotal role in meeting the technical challenges of larger, more efficient vessels. The timing of the orders—aligned with anticipated delivery windows in 2028‑2029—positions GTT to benefit from the next wave of LNG carrier deployments, potentially influencing pricing dynamics and competitive positioning within the maritime energy sector.
