"This award is testimony to the result of the collective efforts of Eidesvik, Subsea 7 and ULSTEIN, and a great inspiration to our long-term innovation efforts," says CEO in Ulstein Group, Gunvor Ulstein.

The cutting edge vessel, designed for operations in the harshest environments, was delivered from Ulstein Verft in January and is co-owned by Subsea 7 and Eidesvik. 'Seven Viking' has been working for Statoil in the North Sea since February.

"'Seven Viking' is tailor-made for IMR operations and has unmatched technical and operational capacity within this sector. She operates in a most satisfactory way and our client is very pleased," comments Subsea 7's Offshore Manager, Vidar Øvstedal.

The ICE-C class vessel, with a crew capacity of 90 and a top speed of 17 knots, works for Statoil on a five-year contract. It has been custom-built according to the operator's specifications to carry out tasks including inspection, maintenance and repair of subsea installations, in addition to scale treatment and RFO (Ready for Operations) work scopes.

'Seven Viking' incorporates the X-BOW® hull line design to reduce motion in transit and give increased stability in the potentially high waves that characterise the North Sea. Despite this enviable stability usually associated with size, this version of the SX148 design from ULSTEIN has been crafted to be compact in stature ? measuring only 106.5 metres long and 24.5 metres wide. The dimensions will allow the 'Seven Viking' to manoeuvre with ease in confined spaces, such as between platforms, accessing difficult to reach areas.
