Norwegian offshore shipbuilder and designer Ulstein has delivered the Island Venture offshore construction vessel (OCV) to a joint venture between Edison Chouest Offshore and Island Offshore.
Ulstein delivered the vessel on Tuesday and said that it was the largest offshore construction vessel from Ulstein Verft so far.
According to the contract signed by Ulstein and Island Ventures II (now named Island Ventures 5), a joint venture between Edison Chouest Offshore (USA) and Island Offshore (Norway), the vessel was expected to be delivered in the third quarter of 2015.
The vessel was originally ordered as a vessel of 147.5 meters in length and 28 meters in the beam. After the ship construction had started, it was decided to increase the deck area and tank capacities. The vessel is now measuring 160 meters by 30 meters.
A 400-tonne crane for operations at 4,000-meter depths and a 140-tonne crane with 3,000-meter wires have been installed. The vessel has three moon pools – two for ROV work and one construction moon pool of 12 x 11.2 meters.
The vessel has been prepared for a possible later installation of a module handling tower by reinforcing the foundations in the moon pool area. A later change order included an upgrade of the accommodation, from 200 to 239 persons.
The OCV was designed for operations such as IMR, ROV services, well intervention and drilling. It has extensive under-deck capacities for liquid and dry substances and a deck load capacity 9,000 tonnes with three separate engine rooms.
