The new vessel “Edda Freya” is specially designed and equipped to suit the Greater North Sea market with the fuel saving environmentally friendly Siemens BlueDrive PlusC propulsion control technology and DP3 positioning system

The modification of these platforms is required in preparation of a possible tie-back from the near-by Maria-development in the Norwegian Sea that is operated by Wintershall. The offshore work includes the installation of risers as well as dynamic umbilical and cable.

The installation operations will be performed by the new build construction and installation vessel Edda Freya that is scheduled to join the DeepOcean fleet in the first quarter of 2016. Additional support will be provided by a light construction vessel from DeepOcean’s fleet for the offshore campaign.

The offshore work, scheduled for the third quarter of 2016, includes the preparation of subsea infrastructure and installation of a dynamic control umbilical, a direct electrical heating (DEH) cable and optional change–out of a production riser on Kristin semi-submersible platform.

A water injection riser will be installed on the Heidrun Tension Leg Platform. The contract was bid in fierce competition and the award confirms DeepOcean’s ability to develop cost efficient and innovative solutions, taking advantage of DeepOcean’s extensive experience in the Greater North Sea. 

“When committing to the Large Construction Vessel Edda Freya  in 2013 we were confident that DeepOcean’s reputation as the leading diverless subsea IMR contractor in the Greater North Sea would provide the foundation for innovative, competitive and reliable performance in SURF projects,” said Ottar Mæland, DeepOcean’s EVP Greater North Sea. “This project success relies on timely execution of complicated installation within close proximity of the Kristin and Heidrun Floating Production Units. The planned operations within the intricate existing riser configuration demands high precision and operational reliability. We are appreciative of Statoil again recognizing DeepOcean’s ingenuity and cost efficient solutions in times of strong cost focus across the subsea value chain.”
