Subsea 7's Vessel Completes First Major Installation Project in North Sea

Subsea 7 Inc. announced that its latest state-of-the-art deepwater Flex / J-lay vessel, the 'Seven Seas,' has completed her first major installation project for StatoilHydro's Yttergryta field in the Norwegian sector of the North Sea.

As part of the StatoilHydro frame-agreement, the Seven Seas carried out two offshore campaigns where a 130Te PLEM, 25Te Flowbase and 6 km dual lay umbilical / 3" MEG line and 3 spools were installed.

The Seven Seas will complete mobilization at Dusavik, Norway for her next project at the BC-10 development in the Campos Basin, Brazil.

The vessel has been designed to perform highly specialized subsea laying, construction and engineering work for the deepwater global offshore pipe oil and gas industry and is capable of operating in water depths of up to 3,000 meters.

Mel Fitzgerald, Chief Executive Officer at Subsea 7, said, "When we took delivery of the Seven Seas we were confident of the exceptional capabilities she would deliver to our clients and we are delighted to see her complete her first installation project. We now look forward to the Seven Seas demonstrating her deepwater capability in the Campos Basin, Brazil."

Having joined the Subsea 7 fleet in June, the Seven Seas is the fourth in a series of eight new vessels joining the fleet between 2007 and 2010, representing a total investment of over $1.8 billion. The vessel was officially inaugurated in April by Mrs Anabela Fonseca, Board Member of Sonangol, Angola's national oil company.

The Seven Seas was also recently confirmed as the lead vessel for Subsea 7's framework agreement with BP Angola Ltd for the development of Block 31.

The vessel was designed and constructed by Merwede Shipyward in the Netherlands. The flexible pipelay equipment, including a vertical lay system with top tension capability in excess of 400 t, and a 400 t deepwater crane, were designed and manufactured by Huisman in Rotterdam as part of a unique commercial agreement which aligns the interests of all parties concerned in the build. The vessel combines state-of-the-art technology with industry leading safety standards.
