Mitsubishi Shipbuilding Concludes Technical Cooperation Agreement with Namura Shipbuilding on LPG powered Very Large LPG/Ammonia Carrier Construction -- Ammonia-loadable Largest LPG powered vessel --

87,000m³ type LPG-powered large LPG/ammonia carrier

Tokyo, August 5th, 2021 – Mitsubishi Shipbuilding Co., Ltd., a part of Mitsubishi Heavy Industries (MHI) Group, has concluded a technical cooperation agreement with Namura Shipbuilding Co., Ltd. relating to LPG(liquefied petroleum gas) powered very large gas carriers (VLGCs) and are capable of transporting both LPG and ammonia. Based on this agreement, Namura Shipbuilding will construct a LPG powered VLGCs on order from MOL Group.

Mitsubishi Shipbuilding has developed an all-new type of VLGC applying its knowledge and expertise accumulated through the construction and delivery of more than 80 VLGCs and midsized LPG/ammonia carriers. Operating performance has been improved by increasing the holding capacity of the cargo tank from the earlier 83,000m³ to 87,000m³, while engineering enhancements have resulted in improved fuel efficiency. In addition, Mitsubishi Shipbuilding has applied its technologies in gas handling to develop a new system capable of using LPG in the cargo hold as fuel to propel the ship. This ability to secure LPG fuel from the cargo tank has a benefit that adds flexibility for the LPG terminal compatibility. Furthermore, the newly developed VLGC features largest-scale at present among all ships capable of carrying ammonia, a point of advantage amid anticipated expansion of demand for large-scale ammonia transportation, which emits zero CO₂ during combustion.

MHI originally concluded a basic agreement with Namura Shipbuilding in 2017 to form a business alliance in commercial ships(Note). Under the newly concluded technical cooperation agreement, Mitsubishi Shipbuilding will not only provide Namura Shipbuilding with technical designs but also procure some equipment and support construction. In this way, Mitsubishi Shipbuilding will provide comprehensive engineering services to support Namura Shipbuilding’s successful construction of the large LPG/ammonia carrier for MOL Group.

Going forward, Mitsubishi Shipbuilding will provide shipbuilding technologies in response to all customer needs as a marine engineering firm handling new ship constructions as well as ships already in service, making no distinctions between vessels constructed in-house and those made by other shipbuilders. In these ways the Company will make ongoing contributions to the development of maritime logistics and also help reduce environmental impact, a critical issue of global scale.
