A newly developed hybrid support structure for independent tanks on board Liquefied Gas Carriers has been awarded Design Approval by Lloyd’s Register (LR), DNV, and the Liberian International Ship & Corporate Registry (LISCR). The solution, which was developed by HD Hyundai Heavy Industries, HD Korea Shipbuilding & Offshore Engineering, and Hyundai Mipo Dockyard, under HD Hyundai Group, is the world’s first application to the independent tank of liquefied gas carriers. 

The solution redefines the role and arrangement of support structures, enhances structural strength, and permits the transition to a safety design that minimises inspections and works in high-altitude areas.

The independent tanks, storing liquefied gas, require structures that support various loads while remaining separate from the hull. The application of the newly developed hybrid support structure allows for rearranging the existing support structure layout while simultaneously minimising the needs for high-risk work and inspections.
