NYK：建造兼容LPG的“双燃料发动机大船”
-携带燃料和使用燃料的多样化-
NYK线：
2021 年 12 月 2 日
我们从川崎重工订购了两个与液化石油气燃料兼容的大型液化石油气/氨气运输船。
两者都计划于2024年完成。
配备双燃料发动机：
除了传统的低硫燃油外，它还配备了同样支持LPG的双燃料发动机。
还使用了使用螺旋桨旋转力的轴带发电机。
可以实现完整的LPG燃料导航。
使用液化石油气燃料：
如果您使用液化石油气作为燃料，
与传统燃油船相比
废气中的 SOx 为 95% 以上，
据说CO2将减少20%或更多。
携带液化石油气和氨水：
这艘船运载液化石油气和氨。
应对各种交易模式
每个货舱分开液化石油气和氨气，
也可以将它们堆叠在一起。

NYK to Build Its First Two LPG Dual-Fuel Very Large LPG / NH3 Gas Carriers
NYK Line Unlike conventional VLGCs,
the vessels will be equipped with separate cargo tanks designed to carry LPG and ammonia at the same time to flexibly respond to various trade patterns.
Ammonia is attracting attention
not only as a raw material for chemicals and fertilizers
but also as a future zero-emission fuel that does not emit carbon dioxide (CO2) when burned.
Furthermore, in addition to the LPG dual-fuel engine,
the ships will have a shaft generator that can generate electricity during the voyage by using the rotation of the shaft that connects the main engine to the propeller.
Since the diesel generator can be stopped during normal seagoing transit,
realizing full navigation with LPG fuel will be possible except for the use of a small amount of pilot fuel.
When LPG is used as fuel,
exhaust gas from the ordered VLGCswill contain at least 95% less sulfur oxide (SOx) and 20% less CO2 compared to NYK’s conventional VLGCs using heavy-oil fired engines.
These new VLGCs will comply
not only with the SOx Global Cap regulations* that were tightened from January 2020
but also with the EEDI phase 3 requirements.** For the time being, all future VLGCs ordered by NYK will be equipped with LPG dual-fuel engines.
