Norway's North Sea Invest AS recently ordered a 145 x 30 m Offshore Construction
Vessels (OCV) from Astilleros Barrera in
Vigo, Spain, with commissioning scheduled for 2010. The OCV is a multi-purpose ships for the oil and gas industry, to be used for the installation of platforms and extraction sys- tems, as well as for the laying of pipelines.
The new OCV can accommodate more than 120 crew members, and it is the largest, most powerful ship ever fitted with Voith
Schneider Propellers (VSP) as its main propulsion systems. Three VSP are installed in the stern, and two in the bow — all five of them type VSP 36R6 EC/280-2. The ship is driven by five electric motors with a total output of 19,000 kW (26,000 hp).
The OCV has two heave compensated cranes that adapt hydraulically to prevailing sea movements, as well as a helipad. During long-term duty on sea, boat and crew can therefore be supplied from the air.
Among the special features of the ship is a redundant dynamic positioning system (DP2) keeping the ship at a given working position, as well as the Voith Roll
Stabilization (VRS), which reduces rolling
