Swan Defence and Heavy Industries Limited (SDHI) has secured a Category 4 order from Energy ONE Limited to build four 92,500 DWT dual-fuel ammonia bulk carriers, marking a first-of-its-kind project in India.
These vessels will be the first ammonia dual-fuel ships constructed in the country and among the largest commercial ships ever built at an Indian shipyard, highlighting a major leap in India’s shipbuilding capabilities.
The ships, measuring 229.5 metres in length with a 37-metre beam, will feature ammonia-based propulsion systems, supporting the global transition toward low-emission shipping. The vessels will be designed by KMS-EMEC (South Korea) and classified by Det Norske Veritas.
Commenting on the development, Vivek Merchant, Director at SDHI, said the order reflects growing global confidence in Indian shipbuilding and the company’s capabilities, while positioning it at the forefront of next-generation green maritime technologies.
The first vessel is expected to be delivered by October 2029, with subsequent deliveries scheduled at four-month intervals.
The project aligns with broader green shipping initiatives, as Energy ONE’s affiliated fund New Energy One (NEO) continues to invest in zero-emission vessels, backed by a planned USD 2 billion capital program.
