About Us
We are a provider of total solutions within offshore / inshore fish farming and also within energy-efficient systems for the maritime industry.
With a global reach, we collaborate with international partners which supply services to our projects. Our focus is to establish sustainable aquaculture solutions through circular economy principles—repurposing the inherent capabilities of vessels, utilizing green energy, energy storage, intake/outlet water purification, and safe handling of sediments.
News
In 2024 a representative of Green Energy Fish Farming (GEFF) has toured China, visiting relevant stakeholders - both owners and institutes that have been involved in the creation of a vessel for offshore operations (i.e., exposed / open sea farming)
In the autumn of 2024, a representative of GEFF gave a presentation at The 5th International Symposium on Offshore Aquaculture, where both GEFF's concept and the current state of offshore fish farming in Norway were showcased.

Chinese vessels
A concept similar to our 2017 concept has been created in China through a new build delivered in 2022; the Guoxin 2-1, where the solution was applied to local fish species like yellow croaker, resulting in 3,200 tons of production in 2024. A new vessel (Suhai 1, see further below) based on the same concept is now being delivered for salmon farming in the cold zone; the northern waters of the China Sea.

Another Chinese company has as mentioned provided a vessel for offshore fish farming. The "Suhai 1" breeding factory ship was designed by the Institute of Fishery Machinery and Instruments of the Chinese Academy of Fishery Sciences and build was commenced by Guangzhou Huangpu Wenchong Shipyard in early 2023, with a total cost of nearly 600 million yuan and delivered in 2025. They are planning on building two vessels with an option of additional two.
