What is the primary function of GTT's tank designs for LNG carriers?

GTT's primary function is to design highly specialized containment systems that safely and efficiently store liquefied natural gas at cryogenic temperatures (around -162°C). These designs prevent boil-off gas, maintain cargo integrity, and ensure the structural stability of the vessel during transport.

Why is Samsung Heavy Industries commissioning a design rather than developing it in-house?

Samsung Heavy Industries, like most major shipbuilders, commissions designs from GTT because GTT holds proprietary, patented technology and extensive intellectual property for these complex cryogenic containment systems. Developing such advanced technology in-house would require immense R&D investment and time, making it more efficient and cost-effective to license GTT's proven and globally recognized designs.

How does this order reflect the current state of the global LNG shipping market?

This order signifies a healthy and growing global LNG shipping market. It indicates sustained demand for new LNG transport capacity, driven by increasing global LNG trade, the need for fleet renewal as older vessels retire, and the expansion of new liquefaction and regasification projects worldwide. Such orders are a strong indicator of long-term confidence in LNG as a crucial energy source.
