1st ammonia-fuelled vessel to operate by ’26

Wärtsilä, Finland-based engine manufacturer, signed a deal with Norwegian shipowner Eidesvik on Monday to convert the Viking Energy, an offshore platform supply vessel, into the world’s first ammonia-fuelled in-service ship.

Scheduled for conversion in early 2026, the vessel, under contract with Equinor, will begin operating on ammonia in the first half of that year.

This innovative project marks a significant milestone in maritime decarbonisation efforts as the industry seeks sustainable fuel alternatives to meet global emissions targets.

The conversion will feature Wärtsilä’s newly launched ammonia solution, including an advanced engine, fuel gas supply system, and exhaust after-treatment system.

Equinor is also financially supporting the project and reinforcing its commitment to sustainability in shipping.

Ammonia is emerging as a key alternative fuel, essential for achieving net zero emissions by mid-century.

Wärtsilä’s recent report highlights that while current measures can reduce shipping emissions by up to 27 per cent, sustainable fuels like ammonia are crucial for eliminating the remaining 73 per cent.

Wärtsilä, Eidesvik, and Equinor are driving this transformation as part of the broader ‘Apollo’ project, co-funded by the Horizon Europe program, which aims to accelerate Europe’s transition to climate neutrality by 2050.

The Viking Energy conversion builds on Eidesvik’s history of pioneering environmental technologies, positioning the vessel as a leader in green shipping innovation.
