From a Local VIP to Global LNG Thermal Solutions supplier : VacuEco Supertech VPU Cryogenic Insulation for LNG Carriers

LNG carriers are known as the tiaras of shipbuilding because of their high technical barriers and construction complexity.

LNG carriers are known as the tiaras of shipbuilding because of their high technical barriers and construction complexity. As global shipbuilding supply chain has matured, core components—including cryogenic steel plate, cargo pumps, and navigation systems—have gradually shifted to domestic supply, and insulation materials for cargo-containment systems have already been localized.

But competition has not stopped there. Shipowners and shipyards now expect more than a workable insulation system: they want higher thermal efficiency, better tank-volume utilization, and more stable long-term performance.

Whether used in the insulation spaces of membrane-type LNG carriers following the Mark III or NO96 designs, or on the external insulation of self-supporting tanks, conventional systems are approaching their limits in thermal conductivity, thickness, and boil-off control at -162°C.

The industry’s next challenge is to use more advanced insulation technology to release cargo volume, reduce energy consumption, and strengthen supply-chain independence.
