NYK books new LPG dual-fuel VLGC with ammonia preparation from KHI Ship’s crew

NYK has ordered its sixth dual-fuel liquefied petroleum gas (LPG) and very large LPG/Liquid Ammonia Gas (VLGC) tanker from Kawasaki Heavy Industries (KHI). The ship will be built by KHI Sakaide Works and will be delivered in 2026.

This vessel is the eighth in NYK’s fleet of LPG-powered LPG tankers and the sixth of a new type of vessel capable of transporting ammonia and responding flexibly to different trading patterns.

Furthermore, in addition to the LPG dual-fuel engine, the ship will have a shaft generator capable of generating electricity during the voyage by utilizing the rotation of the shaft connecting the main engine to the propeller. Since the diesel generator can be turned off during regular sea transport, full navigation on LPG fuel is possible, apart from using a small amount of pilot fuel as an ignition source.

When LPG is used as fuel, the ordered VLGC’s exhaust contains at least 95% less sulfur oxides (SOx) and 20% less CO2 than NYK’s traditional VLGCs with heavy oil-fired engines.

This new VLGC complies with the SOx Global Cap regulations, which have been tightened since January 2020, and the IMO’s Energy Efficiency Design Index (EEDI) Phase 3 regulations, which introduced stricter CO2 emission standards from April 2022.

In addition, the ship is expected to be classified as a VLGC by Nippon Kaiji Kyokai (ClassNK) and have a preliminary design in accordance with the guidelines issued by ClassNK, allowing this ship to use ammonia as a fuel in the future.
