Flocean One

In operation since summer 2026
A world first at industrial scale

The plant

Flocean One is the first subsea desalination plant built at industrial scale. We built and tested it in Oslo, shipped it to Mongstad on Norway's west coast and lowered it to 500 metres in summer 2026. It has made freshwater every day since and sends it ashore through a pipeline.
