据ICIS网站8月10日消息 日本商船三井（MOL）已达成造船协议，全球最大的氨运输船将在2023/2024年进行首次航行。
MOL子公司Phoenix Tankers与Namura Shipbuilding之间的协议涉及建造两艘大型气体运输船（VLGC），以运输液化石油气（LPG）和氨。
每艘油轮的容量约为8.7万立方米，可运载约5.8万吨氨气，比目前运营的最大油轮的容量高出近50%。
南浦造船将与三菱造船有限公司进行技术合作，在其Imari造船厂建造这两艘船舶，但未披露财务细节。
MOL在新闻发布会上表示：“这些船舶也可以使用液化石油气燃料，计划在2023年后陆续交付……旨在最大限度地提高燃油效率。”
氨作为下一代清洁燃料，在燃烧时不会排放二氧化碳，并且作为可用于运输氢气的“氢载体”，正在引起人们的注意。
新订购的船舶还设计用于运输氨，目前是世界上最大规模的氨运输船。
此外，由于液化石油气和氨燃料具有相似的特性，因此，这些船舶的建造将着眼于将来转换为氨燃料。
氨本身是一种肥料，是氮肥和磷肥的关键成分，用于己内酰胺等化工产品，氨的交易十分广泛。
大约160万吨/月的氨由海船运输，每次约有60艘油轮在水面上航行，容量从4000吨到40000吨不等。

Japan's MOL places order for world's largest ammonia tankers
Japan's Mitsui O.S.K. Lines Ltd (MOL) has struck a shipbuilding deal that should see the world’s largest ammonia carriers perform their maiden voyages in 2023/2024.
The agreement between MOL arm Phoenix Tankers Pte. Ltd and Namura Shipbuilding Co. Ltd involves the construction of two very large gas carriers (VLGCs) to transport liquefied petroleum gas (LPG) and ammonia.
With a capacity of around 87,000 cubic metres (cbm) each, the vessels could carry about 58,000 tonnes of ammonia – almost 50% more than the capacity of the largest tankers operating currently.
Namura Shipbuilding will construct the two vessels at its Imari Shipyard, under a technical tie-up with Mitsubishi Shipbuilding Co. Ltd. Financial details were not disclosed.
"The vessels, which can also run on LPG fuel, are slated for delivery in succession after 2023 [... and] are designed to maximise fuel efficiency," MOL said in a news release.
"Ammonia is drawing attention as a next-generation clean fuel that does not emit carbon dioxide when burned, and as 'hydrogen carrier' that can be used to transport hydrogen.
"The newly-ordered vessels are also designed to transport ammonia, and are presently the world's largest-scale ammonia carriers.
"Furthermore, the vessels will be built with an eye toward conversion to ammonia fuelled in the future because LPG and ammonia fuels have similar characteristics."
A fertilizer in its own right, a key component of nitrogen and phosphate fertilizers and utilised in chemical products like caprolactam, ammonia is widely traded.
Around 1.6m tonnes/month of ammonia is moved by marine vessel, with about 60 tankers on the water at any one time, ranging in capacity from 4,000 tonnes to 40,000 tonnes.
