Pipe Laying Vessels
All equipment is fully integrated into the design of the vessel, in the sense that it has been designed according to its functionality. At the same time, the sea keeping characteristics of the vessel have been used as an input for the design of the reel and the pipe lay ramp.
A full width ROV hangar is located aft of the accommodation block. Recessed ROV deployment rails are fitted on both sides of the ship. A 400MT deep-water offshore crane and two additional large deck cranes are provided on the working deck. Furthermore the vessel’s pipe laying equipment has a top tension capability of 400t and a storage capacity of 3,500t of rigid steel pipe on the main reel.
The vessel is a stable platform with a large payload due to the hull form. The stability of the vessel can be controlled and adapted according to different loading conditions by means of upper and lower ballast tanks in the sides. The ship’s motions can be further reduced by two independent anti-rolling tanks.
Recent advances have been made, with pipe being laid in water depths of more than 2,500 meters.
