LR and LISCR award Design Approval for world’s first 22,000cbm multi-gas carrier


Lloyd’s Register (LR) and the Liberian International Ship & Corporate Registry (LISCR) have awarded Design Approval to HD Korea Shipbuilding & Offshore Engineering (HD KSOE) and Hyundai Mipo Dockyard (HMD) for the development of the world’s first 22,000cbm multi-gas carrier as part of a Joint Development Project for LCO2 Carrier design and development. A ceremony to mark the event was held at Nor-Shipping (pictured).

The vessel will be capable of carrying Liquified Carbon dioxide (LCO2), Liquid Petroleum Gas (LPG), Ammonia (NH3) and Vinyl Chloride Monomer (VCM) and incorporates a new type of steel in its tanks that supports greater efficiency in the carbon capture and storage (CCS) value chain.

The steel used in the Type C tank construction for multi-gas will make scantling lighter whilst keeping intact the tanks’ structural integrity. This innovation allows an upscale in the size of the carrier, improving storage and transportation, something shipbuilders are not able to do with more conventional materials.

As part of the Design Approval process, LR will provide advice and guidance on technical regulations and the development of a Type C storage tank for using the new material. The Liberian Flag Administration will liaise with LR to formalise the approval and provide the required certification to allow the multi-gas Carrier to enter service.

When built, the carrier will transport liquefied carbon dioxide under pressure, allowing carbon from the CCS process to be transported to storage facilities.

HD KSOE & HMD have developed three different LCO2 carriers to respond to the market demands of different business models in the CO2 value chain, which include a 12,000cbm LCO2 carrier with medium pressure cargo tanks, a 22,000cbm LCO2 carrier with low pressure cargo tanks and a 30,000cbm LCO2 carrier with low pressure cargo tanks.

Andy McKeran, Lloyd’s Register, said: “This Design Approval demonstrates LR’s expertise in supporting the advance of ground-breaking maritime projects in a safe, sustainable way. This multi-gas carrier will be a key piece of infrastructure in the carbon capture and storage value chain, helping remove greenhouse gases from the atmosphere, supporting the progress to a net zero carbon economy.”
Yi-hyo Chung, Senior Vice President, HMD, said: “This is the first result of the JDP of new steel for liquefied CO2 carriers signed in August 2021, allowing us to design & build more economical and efficient carriers. The developed new material has been examined and approved based on the mechanical properties experiment and engineering assessment.

“We are very pleased to share the result of this development show as we prepare to build customized economical liquefied CO2 Carriers.”
Thomas Klenum, Executive Vice President, Liberian Registry, said: “Carbon capture is one of the keys to unlock the potential to fully decarbonise international shipping and other industries in the fight against climate change, and therefore the Liberian Registry is very proud to contribute with an Approval in Principle to HD KSOE and HMD for their innovative multi-gas carrier design featuring a new steel type for the cargo tanks allowing multiple gases to be safely and efficiently transported including liquefied CO2.

“This JDP between HD KSOE, HMD, POSCO, LR and LISCR demonstrates that international collaboration can pave the way for innovation in ship design and a sustainable future for our maritime industry.”
