The subsea development vessel, with its extremely dependable propulsion and DP3 system, was designed with a concentrate on cable laying operations, offshore development and IMR operations. The vessel’s first mission can be with DeepOcean, performing set up work for Statoil on the Maria growth within the Norwegian Sea and particularly, the modification of the Statoil platforms Kristin and Heidrun.

The Edda Freya, with a size of 150 meters, a width of 27 meters and a pair of,300 sq. meters of whole deck house. The vessel is provided for such offshore work with a 150T twin tensioner vertical lay system and a 3000-ton carousel located beneath deck.
