A new design for an ultra large ethane carrier (ULEC) and a patented insulation system for Type B low-temperature cargo tanks, both developed by China’s Jiangnan Shipyard, have been awarded approvals in principle (AiP) by ABS.
The ULEC design is the first large gas carrier to be developed with a BrilliancE® II Type B cryogenic liquefied gas cargo containment system. The insulation system, PnFCOMBi, the second modification of a design originally released in 2019, is suitable for liquefied gas cargoes and temperatures down to -163°C.
Commenting on the new gas carrier design, the classification society’s President and COO, John McDonald said: “With ethane demand continuing to rise, the ultra large carrier design promises to support the market for many years, and the new insulation system is another innovative technology from Jiangnan supporting the overall safety of gas carriers.”
Jiangnan Chief of Corporate Technology, Keyi Hu, commented: “The groundbreaking BrilliancE® II Type-B cargo containment system represents a significant leap forward in gas carriers. Its lightweight features make a three-tank configuration feasible without any concern regarding sloshing and structural resonance. It offers numerous advantages, including exceptional safety, better space efficiency and parallel construction of tank and hull. We are confident that ULEC, with its advanced technology, will deliver significant advantages and value to shipowners.”
