Wärtsilä and Eidesvik to Convert ‘Viking Energy’ into First Ammonia-Powered Ship by 2026

In a pioneering move for the maritime industry, Wärtsilä and Eidesvik Offshore have announced plans to convert the offshore platform supply vessel ‘Viking Energy’ into the world’s first ammonia-fueled ship. This groundbreaking project, set for completion in 2026, is poised to set a new benchmark in sustainable shipping practices.

The initiative, supported by energy major Equinor, which both charters the vessel and contributes to the project’s funding, underscores the growing importance of alternative fuels in the race to achieve net-zero emissions in the shipping sector. Ammonia, identified as a key component in meeting the International Maritime Organization’s (IMO) mid-century net-zero target, is gaining traction as a viable option to significantly reduce the maritime industry’s carbon footprint.

Wärtsilä’s recent findings highlight the urgent need for sustainable fuels like ammonia to bridge the gap left by current emissions reduction strategies, which can only achieve a 27% cut. The remainder, according to industry leaders, must be addressed through the adoption of alternative fuels.

Håkan Agnevall, President and CEO of Wärtsilä, emphasized the urgency of this transition, noting that “In just 25 years – the lifetime of a single vessel – shipping needs to get to net zero emissions.” He called for coordinated efforts across the maritime industry to facilitate the system changes necessary for the acceptance and integration of these new fuels.

The collaboration between Wärtsilä, Eidesvik, and Equinor builds on a history of innovation, including the introduction of the world’s first LNG-powered offshore platform supply vessel and the pioneering Battery Power notation awarded to Viking Energy. This latest conversion, part of the ‘Apollo’ initiative under the Horizon Europe framework, aims to further advance the industry’s decarbonization goals by establishing ammonia as a credible and sustainable fuel option.

Eidesvik Offshore’s CEO & President, Gitte Gard Talmo, highlighted the importance of collaboration in driving the green transition, stating, “Close collaboration throughout the value chain is key to succeed in the green transition.” Eidesvik’s longstanding commitment to reducing emissions positions the company as a leader in implementing innovative technologies, with this project marking another significant step forward.

The conversion will include the integration of Wärtsilä’s comprehensive ammonia solution, encompassing engine technology, fuel gas supply systems, and exhaust after-treatment. Once operational by mid-2026, the ammonia-fueled Viking Energy will represent a significant leap toward decarbonizing the shipping industry and could pave the way for broader adoption of sustainable maritime fuels.
