NYK to build its fifth LPG dual-fuel very large LPG / ammonia carrier
NYK has announcedthe order of its fifth liquefied petroleum gas (LPG) dual-fuel very large LPG / liquefied ammonia gas carrier (VLGC) from Kawasaki Heavy Industries Ltd. (KHI). The ship will be built at the KHI Sakaide Works shipyard and is set for delivery in 2026, according to the company's release.
This vessel is the seventh in NYK's fleet of LPG-fueled LPG carriers and the fifth in a new type of vessel that is also capable of carrying ammonia and will be equipped with separate cargo tanks designed to carry LPG and ammonia at the same time to flexibly respond to various trade patterns.
Furthermore, in addition to the LPG dual-fuel engine, the ship will have a shaft generator that can generate electricity during the voyage by using the rotation of the shaft that connects the main engine to the propeller. Since the diesel generator can be stopped during normal seagoing transit, realizing full navigation with LPG fuel will be possible except for the use of a small amount of pilot fuel.
When LPG is used as fuel, exhaust gas from the ordered VLGC will contain at least 95% less sulfur oxide (SOx) and 20% less CO2 compared to NYK’s conventional VLGCs using heavy-oil fired engines.
This new VLGC will comply not only with the SOx Global Cap regulations that were tightened from January 2020 but also with the IMO’s Energy Efficiency Design Index (EEDI) Phase 3 regulations, which implemented stricter CO2 emission standards from April 2022.
Moreover, the vessel is expected to be given notations by Nippon Kaiji Kyokai (ClassNK) as a VLGC that has a preparatory design in accordance with the guidelines issued by ClassNK so that this vessel may use ammonia fuel in the future.
