据海上能源4月19日报道，日本川崎重工与日本海运公司日本邮船签订了以液化石油气和液化氨气为燃料的船舶合同。

这是日本邮船的第三艘LPG/NH₃船，同时也是川崎重工将建造的第76艘LPG船、第13艘LPG燃料LPG船和第6艘LPG/NH₃船。

这艘86700立方米的货船配备了单独的货舱，可以同时装载LPG和NH₃，预计将于2024年完工。

川崎重工表示，与传统货运船相比，这艘新的运输船还将具有更大的货舱容量。

它将使用低硫燃料油和液化石油气，据说与船用燃料油相比，这将大大减少废气中的硫氧化物、二氧化碳等污染物的排放量。

因此，该船将符合国际海事组织(IMO)制定的SOx排放标准，以及国际海事组织(IMO)的能源效率设计指数(EEDI)第三阶段规定，该规定适用于在2022年采用更严格的二氧化碳排放标准。

此外，这艘船还配备了一个轴发电机，可以将主机的旋转能量转换为电能。这使船只能够在正常航行条件下停止使用所有柴油发电机。

Kawasaki Heavy scores third LPG/ammonia carrier deal with NYK

Japanese shipbuilder Kawasaki Heavy Industries (KHI) has secured a contract with the compatriot shipping company Nippon Yusen Kabushiki Kaisha (NYK) for the construction of a liquefied petroleum gas (LPG) and liquefied ammonia gas (NH3) carrier powered by LPG fuel.

This is the third LPG/NH3 carrier for NYK and simultaneously the 76th LPG carrier, 13th LPG-fueled LPG carrier and sixth LPG/NH3 carrier to be constructed by Kawasaki.

The construction of the 86,700 cbm vessel, equipped with separate cargo tanks to carry LPG and NH3 at the same time, is expected to be completed in 2024.

The newbuild will also feature the greater capacity of the cargo tanks as compared to conventional carriers, KHI said.

It will run on low-sulfur fuel oil and LPG which is said to significantly reduce the emission volumes of sulfur oxides (SOx), CO2, and other pollutants in the exhaust gases as compared to marine fuel oil.

Thus, the vessel will meet SOx emission standards set by the International Maritime Organization (IMO), as well as the IMO’s Energy Efficiency Design Index (EEDI) Phase 3 regulations, which are applicable to adopt stricter CO2 emission standards in 2022.

In addition, the vessel comes with a shaft generator that converts the rotational energy of the main engine into electric power. This enables the vessel to stop all the diesel generators under normal sea-going conditions.
