In September 2018, the LNG carrier newly developed by Jiangnan Shipbuilding with GTT membrane Mark III Flex containment system obtained the DNV GL Design Approval in Principle (AiP) certificate. The design of this flexible, efficient, and environmentally friendly LNG carrier was developed by Jiangnan Shipbuilding in cooperation with MARIC, GTT, DNV GL, and major equipment manufacturers.

In May 2021, Jiangnan Shipbuilding and Guangdong Jiufeng Energy signed an order for a 79,800 cubic meter MARK III membrane-type LNG carrier, officially entering the field of membrane-type liquefied gas ship construction.

So far, Jiangnan Shipbuilding has achieved full coverage of the R&D, design, and construction capabilities of the full spectrum of liquefied gas ships equipped with Type A, Type B, Type C, and membrane low-temperature liquefied gas containment systems. Jiangnan Shipbuilding has a professional training workshop and a low-temperature laboratory for the MARK III enclosure system, which can systematically train various professional types of work to achieve rapid adjustment of peak and valley demand for human resources; Jiangnan Shipbuilding is also preparing to build an intelligent three-dimensional warehouse and expand training. Center, experimental equipment resources, etc., provide better conditions for the production line of large-scale membrane LNG carriers and LNG fuel tanks to ensure the smooth progress of subsequent construction.

While possessing rich technical reserves, Jiangnan Shipbuilding has also gained market recognition with its high-quality services. This project is the second cooperation between Jiangnan Shipbuilding and ADNOC. In 2020, AW Shipping, a joint venture between ADNOC L&S and Wanhua Chemical, has ordered five 86,000-cubic-meter dual-fuel VLGCs in Jiangnan Shipbuilding. At present, the project is progressing smoothly. In the process of cooperation, a deep friendship has also been established, which has laid a solid foundation for the two parties to cooperate again in this large-scale LNG project.
