Eidesvik Offshore’s Viking Energy Enters Dock for Ammonia-Powered Conversion
Eidesvik Offshore’s platform supply vessel (PSV) Viking Energy has entered the dock at Halsnøy Dokk to begin its conversion to ammonia-powered operations.
The conversion is scheduled to be completed in autumn. Once finished, the 95-meter-long vessel will continue operating for Equinor, with which it has been on continuous contract since its delivery in 2003.
Scope of the Viking Energy Conversion
The work includes prefabrication of steel and piping systems, major structural modifications, installation and integration of a new ammonia dual-fuel engine, an ammonia tank and fuel systems, as well as technical upgrades.
Wärtsilä Marine will deliver its 25 dual-fuel engine, capable of operating on ammonia and marine gas oil. Breeze Ship Design is responsible for the ship design and engineering.
The design package has also received a preliminary assessment from the Norwegian Maritime Authority.
Ammonia Retrofit Could Cut Emissions by 70%
The conversion is said to have the potential to reduce greenhouse gas emissions by 70% or more.
According to Eidesvik, once the retrofit is completed, Viking Energy will become the first offshore vessel capable of operating on ammonia. It will also mark the first actual project in the industry to test ammonia as fuel for a vessel in normal operation.
“This milestone represents a decisive step forward in advancing low-emission offshore operations and demonstrates how industrial partnerships can accelerate the energy transition at sea,” Eidesvik Offshore said.
“With the potential to significantly reduce greenhouse gas emissions, this project highlights how industrial partnerships, technology and operational experience can come together to accelerate the energy transition at sea.”
