DP Pipelay Vessels
Both are dynamically positioned (DP) pipelay vessels capable of operating in water depths of up to 3,000 m and suitable for operations worldwide. Designed by IHC in close collaboration with Subsea 7, each vessel is fitted with two under-deck storage carousels with a capacity for 2,500 t and 1,500 t of product respectively.
A vertical (tiltable) lay system with a 550 t top tension capacity is permanently installed for the deployment of a range of flexible products with a diameter of 50-650 mm. The lay tower can operate at up to 10° from the vertical and is fitted with two wire centralisers and with two tensioners, each with a 275 t capacity, that can be retracted clear of the firing line. The pipelaying systems are delivered by Huisman.
