Equinor, Eidesvik and Wartsila partner on first ammonia-fueled supply vessel

Equinor has signed a contract with Norwegian shipowner Eidesvik Offshore for the conversion of the Viking Energy supply vessel to ammonia operation. The vessel, which supplies Equinor's installations on the Norwegian Continental Shelf (NCS), will be fully converted and put into operation with low emissions in 2026.

Technology group Wärtsilä has signed a contract with Eidesvik to supply the equipment for the conversion of the offshore platform supply vessel to operate with ammonia fuel.

The partners report that Viking Energy will be the world's first supply vessel fueled by ammonia.

By converting the vessel to ammonia operation, Eidesvik and Wärtsilä say they will cut emissions from Viking Energy by at least 70%.

Equinor and Eidesvik have a 21-year history of collaboration on environmental technology on Viking Energy. At the time of delivery in 2003, the vessel was the world's first LNG-fueled supply vessel. The vessel was also the first in the world to receive DNVs "Battery Power" notation.

Equinor also will contribute significantly to funding the conversion to ammonia operation. The project receives EUR5 million (US$5.5 million) in support through the EU Horizon Europe program.
