The VCR system can adjust the air compression ratio in the engine combustion chamber to an optimal balance according to engine power and LNG fuel properties.
The study is the latest among shippers including North Sea Container Line, MOL and Bunker Holding that are exploring ammonia as an alternative marine fuel as they seek ways to cut emissions and meet decarbonisation goals.
In the future, based on the studies carried out, NYK will establish a system to collect and aggregate Scope 3 emissions data while continuing to utilize the existing aggregation system.
The vessel will continue to be operated by Shin-Nihon Kaiyosha to verify its decarbonization effect and operational safety as the world's first ammonia-fueled vessel.
On September 12 2023, Japan Suiso Energy and three Japanese shipping companies, “K” LINE, MOL, and NYK, have agreed to join JSE Ocean, a subsidiary of JSE.
NYK and TBG will significantly enhance the safety of supplying ammonia, which is highly toxic, to ships by employing TBG's technology to ensure that the liquid does not leak.
