Ammonia-Fuel Ready LNG-Fueled Vessel Proceeds to Actual Design Viable, functional, and safe concept design completed Nov. 28, 2022 Nippon Yusen Kabushiki Kaisha MTI Co., Ltd. Elomatic Oy
A "concept design" includes ship specifications such as overall length and width, load capacity, voyage distance, ship speed, etc, for a vessel building. NYK has set a long-term target of net-zero emissions of greenhouse gas (GHG) by 2050 for the NYK Group's oceangoing businesses, and aims at launching zero-emission ships that run on low-environmental-load marine fuels, such as ammonia or hydrogen, in the future. NYK is positioning LNG, a low-carbon marine fuel, as a bridge-solution until future zero-emission ships are realized, and has thus been expanding its fleet of LNG-fueled vessels. 
Announcement on 3 March 2022, "Concept Design for Ammonia-Fuel Ready LNG-Fueled Vessel Completed" Now, the three companies have completed the concept designs of a capesize bulk carrier and a very large crude oil tanker (VLCC) in Phase 1.5 of the project. The main challenges in designing and developing ARLFVs are as follows: 1. Because of the lower energy density of ammonia compared to LNG, a larger fuel tank capacity is needed in order to maintain the same level of endurance. 2. Because of (1), the space for cargo loading, as well as the loadable cargo weight, is reduced. 3. A bigger fuel tank and additional fuel tanks affect ship stability and hull strength. 4. Due to the extreme toxicity of ammonia, ventilation for the ammonia tanks must be designed according to international conventions and/or domestic laws. 5. Conversion from an LNG-fueled vessel to an ammonia-fueled vessel requires additional work periods and costs. In the Phase 1.5 concept design, NYK, MTI, and Elomatic sought solutions to solve the above issues, and researched and studied the fuel-tank layout and other specifications of the ship. The three companies then completed a concept design that has viable, functional, and safe features. Details of the concept design Compared to a conventional LNG-fueled vessel, the ARLFV in this concept design is expected to feature a conversion-cost reduction of 12% for a capsize bulk carrier and 25% for a VLCC. In the next step, i.e., Phase 2 of the project, the three companies will work with shipyards and marine equipment manufacturers on the actual design of the ARLFV based on the concept design.

In March this year, NYK released the updated "NYK Group ESG Story 2022," which introduces initiatives for integrating ESG into the Group's management strategies set forth in the "NYK Group ESG Story" and provides a partial explanation of the Group's sustainable growth strategy from a long-term perspective. To strongly promote ESG management, NYK will continue to create new value as a sustainable solution provider.
