In June 2005, Merwede shipyard  B.V. won the contract to develop and build the new Rigid Reeled Pipelay / Offshore Construction ship for Subsea 7. The pipe lay installation is designed and developed by Huisman-Itrec. 

The construction ship, of which the keel lay took place on 20 February 2006, was launched on 22 September 2006. The ship is fully dynamically positioned, suitable for worldwide operations and designed to lay pipes from a reel and be used for offshore construction work. The ship is also equipped with a fully integrated 6,6 kV electrical installation and propelled by three electrically driven rudder propellers with fixed screws in nozzles at the back. In the fore part of the ship, two electrically driven rudder propellers with fixed screws in nozzles are fixed in addition to a bow thruster.

 A complete ROV hangar is placed behind the accommodation, the vertical ROV tube is placed at the side of the ship, both port and starboard. A 400 MT offshore crane is placed port amidships and two offshore deck cranes, one starboard at the fore part and one port at the back of the deck.  Behind the main pipe spools, an open deck of at least 650 m2 is realised. The pipe lay has been realised at the back of the ship. Around the fence, some work platforms have been realised.
