Merwede Shipyard received a contract to design and build a Reeled Rigid Pipe laying/Offshore construction vessel for

Subsea 7. The pipe laying equipment will be designed and built by Huisman Itrec.

Delivery of the vessel will take place in the second quarter of 2007. SIEM, through its subsidiary Subsea 7, have signed contracts for a new rigid pipelay and construction vessel. The overall pro- ject cost is in the $180-$200 million range and is based on fixed prices from Mer- wede Shipyard and the pipelay equipment supplier.

The ship will be a fully Dynamic Posi- tioned Reeled Rigid Pipe laying/Offshore

Construction Vessel, suitable for world- wide operation. The vessel is designed for reeled rigid pipe laying and offshore con- struction work. It will have a 6.6 kV inte- grated electric power generation system, and propulsion by three electro-motor dri- ven 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 locat- ed after of the accommodation block. Ver- tical ROV deployment rails will be fitted in the ship's sides port and starboard. A large 400 MT offshore crane will be locat- ed on the port side of the vessel amid- ships. Two other large offshore deck cranes will be located one on the star- board 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.
