Japanese yard Kawasaki Heavy Industries (KHI) has won a shipbuilding contract for one 86,700cu.m liquefied petroleum gas (LPG) and liquefied ammonia gas (NH3) carrier from Japanese shipping group Nippon Yusen Kabushiki Kaisha (NYK).
The 230m-long and 37.2m-wide vessel will be dual-fuelled and capable of using LPG as fuel. It will be equipped with separate cargo tanks designed to carry LPG and NH3 at the same time.
Kawasaki plans to complete the construction of the vessels at its Sakaide Works in 2024.
A feature is the greater capacity of the cargo tanks as compared to conventional carriers, which was achieved without significantly changing the vessel’s length, breadth, or other main specifications. Propelled by low-sulphur fuel oil and LPG, the vessel will meet sulphur oxide emission standards set by the International Maritime Organisation (IMO). The vessel will also be equipped with a shaft generator which converts the rotational energy of the main engine into electric power. This enables the ship to stop all the diesel generators under normal sea-going sailings.
