據海上能源4月19日報道，日本川崎重工與日本海運公司日本郵船簽訂了以液化石油氣和液化氨氣為燃料的船舶合同。

這是日本郵船的第三艘LPG/NH₃船，同時也是川崎重工將建造的第76艘LPG船、第13艘LPG燃料LPG船和第6艘LPG/NH₃船。

這艘86700立方米的貨船配備了單獨的貨艙，可以同時裝載LPG和NH₃，預計將于2024年完工。

川崎重工表示，與傳統貨運船相比，這艘新的運輸船還將具有更大的貨艙容量。

它將使用低硫燃料油和液化石油氣，據說與船用燃料油相比，這將大大減少廢氣中的硫氧化物、二氧化碳等污染物的排放量。

因此，該船將符合國際海事組織(IMO)制定的SOx排放標準，以及國際海事組織(IMO)的能源效率設計指數(EEDI)第三階段規定，該規定適用于在2022年采用更嚴格的二氧化碳排放標準。

此外，這艘船還配備了一個軸發電機，可以將主機的旋轉能量轉換為電能。這使船只能夠在正常航行條件下停止使用所有柴油發電機。

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.
