The 86,500-cu m ships, including an on-deck tank capacity of 2,500-cu m, will be built at KHI Sakaide Works shipyard and are scheduled for delivery in 2022. Financial details of the deal were not disclosed.
NYK said that when LPG is used as marine fuel, exhaust gas from the VLGCs will container at least 85% less sulphur oxide (SOx) and 15% less carbon dioxide (CO2) compared to conventional VLGCs equipped with fuel oil-based engines.
The new VLGCs will comply not only with IMO 2020 global sulphur cap regulation but also the EEDI phase 3 requirements.
In addition, by equipping the ships with LPG tanks on deck, it will be possible to load LPG for fuel separately from the LPG cargo.
“In the future, by promoting the development of an eco-friendly fleet, NYK will provide customers with a low-carbon transportation mode and contribute to the reduction of environmental loads and the realisation of a sustainable global society,” NYK stated.
