Eidesvik Offshore has signed a contract with Norwegian shipyard Halsnøy Dokk for the retrofit of the platform supply vessel Viking Energy to run on ammonia fuel. Prefabrication of steel and piping systems will shortly commence, and be completed later in 2026. Major structural modifications, installation and integration of a Wärtsilä 25 ammonia dual-fuel engine, ammonia tank and fuel systems, and further technical upgrades make up the retrofit, after which testing and commissioning will occur. Project Apollo partners indicate that the ship will be available for ammonia-powered operations after delivery later this year, with Equinor to charter the vessel.
This is a defining moment for Apollo. With the yard contract signed, the project takes a decisive step towards demonstrating what is possible when it comes to ammonia as a maritime fuel.
Emilie Dorgeville, Project Co-ordinator of Apollo, in the project’s official press release, 26 Feb 2026
Ammonia‑fuel technology is ready, and we’re excited to bring that capability onboard Viking Energy. It’s been extremely rewarding to work closely with our partners to apply a fully integrated ammonia solution – combining engine technology, fuel supply, and safety systems – to an existing vessel. This project marks an important milestone in supporting the maritime industry’s journey towards zero‑emission operations.
Stefan Nysjö, Vice President of Power Supply, Wärtsilä Marine, in Project Apollo’s official press release, 26 Feb 2026
This is exactly how maritime decarbonisation must happen. This is a bold industrial partnership combined with structured learning and regulatory alignment.
Håvard Tvedte, Interim CEO of Maritime CleanTech, in Project Apollo’s official press release, 26 Feb 2026
The Apollo consortium brings together eight European partners: Equinor, Eidesvik Offshore, Maritime CleanTech, Wärtsilä, Breeze Ship Design, DEME Group, VTT Technical Research Centre of Finland and the National Centre for Scientific Research “Demokritos”.
