KHI to construct new LPG dual-fuel VLGC for NYK Line

NYK’s fourth LPG dual-fuel VLGC will be built at the KHI Sakaide Works shipyard.

Kawasaki Heavy Industries (KHI) has received a contract from Nippon Yūsen Kabushiki Kaisha (NYK) Line to build a new liquefied petroleum gas (LPG) dual-fuel very large LPG / liquefied ammonia gas (NH₃) carrier (VLGC).

Expected to be delivered in 2025, the vessel will be NYK’s fourth VLGC constructed at the KHI Sakaide Works shipyard.

The new vessel will feature separate cargo tanks that will allow LPG and ammonia to be carried simultaneously.

NYK’s new ship will also include a shaft generator, which will be capable of using the rotation of the shaft linking the main engine and the propeller to generate electricity during the voyage.

The 230m-long vessel will have a breadth of 37.20m, depth of 21.90m and summer draft of 11.65m, as well as a tank capacity of approximately 86,700m³.

LPG fuel can be used for full navigation by stopping the diesel generator during normal seagoing transit, stated NYK.

Compared to NYK’s conventional carriers, which use heavy-oil-fired engines, exhaust gas from the new VLGC will have at least 95% less sulfur oxide (SOx) and 20% less CO₂ when LPG is used as the fuel.

NYK said in a statement: “This new VLGC will comply not only with the SOx Global Cap regulations that were tightened from January 2020 but also with the International Maritime Organization’s (IMO) Energy Efficiency Design Index (EEDI) Phase 3 regulations, which implemented stricter CO₂ emission standards from April 2022.”

Last week, NYK Line’s affiliate Knutsen NYK Offshore Tankers (KNOT) took delivery of its first dual-fuel liquefied natural gas (LNG) shuttle tanker.
