Pioneering LNG carrier with type B tank design granted AiP

The midsize LNG carrier design was the result of a joint development project (JDP) between the two parties launched in January 2020.

Under the JDP, LR’s role was to review the suitability and risks of the design which involved a structural design assessment and fatigue design assessment. This included a crack propagation analysis and a design review in accordance with the latest applicable LR Class Rules and Guidance and IMO regulations, which resulted in the AiP.

“Based on LR’s certification, we will continue to respond to the strengthening of environmental regulations by IMO, while also pioneering this new LNG carrier design,” said HMD design division managing director Young–Joon Nam. “Through this AiP, we have developed innovative technology that applies to an IMO type B cargo tank, which offers high space utilisation to the 30,000-m³ LNG carrier. Our design is also expected to gain a competitive edge in terms of its scalable applicability towards the mid-sized LNG carrier market,” he added

“With the maritime industry focused on ensuring safety and efficiency, it’s important we look at alternatives such as the IMO type B tank, which not only helps shipowners and operators optimise space on board but also supports the industry’s wider emissions ambition,” said LR North East Asia technical support office manager Young-Doo Kim. “We’re proud to award Hyundai Mipo Dockyard approval in principle for its 30,000-m³ LNG carrier design with IMO type B tank – a first for a middle-sized LNG carrier market,” added Mr Kim.
