Chinese gas owner Tianjin Southwest Maritime is moving deeper into ammonia transportation with ammonia dual-fuel LPG carriers on order and a new cooperation on very large ammonia carrier designs, while Jiangnan Shipyard builds 90k-class VLACs for Middle East and Chinese clients. Together, these moves show that ammonia is shifting from a niche chemical cargo toward a large-scale energy commodity and potential marine fuel, with long-haul VLAC trades likely to shape gas carrier supply, yard slots and ton-mile demand into the late 2020s.

Ammonia VLAC shift in 30 seconds
Chinese owners and yards are lining up very large ammonia-capable gas carriers for delivery late this decade, alongside ammonia dual-fuel LPG tonnage. The move links shipbuilding, engine makers and export projects around the idea that ammonia could become a mainstream seaborne energy cargo, not just a niche chemical trade.
Ammonia at VLAC size: how the puzzle fits together
Orders and cooperation deals around very large ammonia capable gas carriers in China signal that ammonia is moving from a niche chemical cargo toward a structured energy trade. The late 2020s look set to test whether long haul ammonia flows can sit alongside LNG and LPG as a third leg in the gas shipping portfolio.
First wave targets late 2020s
Very large ammonia capable gas ships
Chinese owners and yards are lining up large gas carriers that can lift ammonia at scale, with designs that also handle LPG or ethane so they can trade before dedicated ammonia routes fully form.
Deliveries into the late 2020s
Lead times for complex gas ships mean hulls ordered now will arrive close to 2028 and beyond, which overlaps with many planned low carbon ammonia production projects and pilot fuel corridors.
Export hubs to energy demand centers
Early VLAC employment is expected to concentrate on long routes between large export projects in the Middle East or Atlantic basin and major power or industrial hubs in Asia and Europe.
Where VLACs sit in a future ammonia value chain
Gas shipowners
Balancing today’s LPG and ethane trades with tomorrow’s ammonia flows.
- Ammonia capable designs allow ships to earn in traditional LPG trades while early ammonia routes build out.
- Portfolio decisions now influence how much exposure owners have to a possible third gas leg alongside LNG and LPG later in the decade.
Charterers and producers
Linking production decisions to available hulls.
- Long term offtake contracts and subsidies matter less if there is not enough suitable tonnage to move product out of export basins.
- Working with early VLAC owners can help match ship specifications to terminal layouts and contract structures from the start.
Ports and terminals
Infrastructure choices decide who can handle the largest ships.
- Draft, jetty strength, storage and safety systems must be sized with VLACs in mind or the largest parcels will go elsewhere.
- Ports that already serve LNG and LPG at scale can often adapt faster to ammonia handling and safety requirements than new greenfield sites.
Where the upside sits
If projects and policy line up as planned.
- Ammonia capable VLACs add a new source of ton mile demand on long routes that complement existing gas trades.
- First mover fleets can offer full chains that link large export projects, shipping and receiving hubs into integrated logistics packages.
- Demonstrated safe operation of big ammonia cargoes improves confidence for financiers, regulators and end users.
Where friction remains
If assumptions about scale or timing prove optimistic.
- Delays in project sanctioning or policy support could leave early VLACs leaning more heavily on LPG and petrochemical trades than originally planned.
- Ammonia safety, crew training and public acceptance issues may slow the spread of ammonia as a marine fuel, even if cargo trades go ahead.
- Competing low carbon fuels or technologies could limit the share of energy demand that ammonia ultimately secures.
Tianjin Southwest’s ammonia capable orders and the VLAC concepts emerging at leading Chinese yards show that the industry is preparing for ammonia to play a much bigger role in seaborne energy trades. The ships now on the drawing board will arrive just as the first wave of large export projects and policy frameworks for low carbon ammonia are tested in practice. Whether these vessels become the backbone of a new long haul commodity trade or remain a specialised part of the gas fleet will depend on how quickly production, infrastructure and end user demand move from plans to sustained volumes over the second half of the decade.
