SubSea 7 Orders New Offshore

Construction Vessel

Merwede Shipyard received a contract to design and build a Reeled Rigid Pipe lay- ing/Offshore construction vessel for Subsea 7. The pipe laying equipment will be designed and built by Huisman Itrec.

Delivery of the vessel is scheduled for 2Q 2007. SIEM, through its subsidiary Subsea 7, signed contracts for a new rigid pipelay and construction vessel. The overall project cost is in the $180-$200 million range and is based on fixed prices from Merwede

Shipyard and the pipelay equipment suppli- er. The ship will be a fully Dynamic

Positioned Reeled Rigid Pipe laying/Offshore Construction Vessel, suit- able for worldwide operation. The vessel is designed for reeled rigid pipe laying and off- shore construction work. It will have a 6.6 kV integrated electric power generation sys- tem, and propulsion by three electro-motor driven fixed pitch propellers in azimuthing nozzles aft. Two retractable Azimuth thrusters will be fitted in the forward part of the vessel; one transverse thruster will be arranged in a tunnel forward.

A full width ROV hangar will be located after of the accommodation block. Vertical

ROV deployment rails will be fitted in the ship's sides port and starboard. A large 400

MT offshore crane will be located on the port side of the vessel amidships. Two other large offshore deck cranes will be located one on the starboard side at the forward end of the main working deck and one on PS at the aft end of the main working deck.

Aft of the main pipe lay reel, a clear deck area of at least 650 sq. m. will be arranged.

A pipelay ramp will be located at the aft end of the ship. Cantilevered work platforms will be provided at each side of the transom at main deck level.
