This is the final pipelaying vessel in a series of three ordered by Subsea 7, and the naming ceremony was performed by Sally Rosa, wife of Ricardo Rosa, chief financial officer, Subsea 7.
Seven Cruzeiro has an overall length of 145.9m, and breadth of 30m. The vessel can accommodate 120 people, and has an operational deadweight of 7025-tonne, and a maximum deadweight of 11,750-tonne.
The Seven Sun, launched on 19 December 2014 in Kinderdijk and the second vessel of this series, was also officially named at the event by Lilian Camozzato, wife of Guilherme Camozzato, director of operations, Subsea 7 Brazil.
Both are dynamically positioned pipelay vessels capable of operating in water depths of up to 3000m 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 2500-tonne and 1500-tonne of product respectively.
A vertical (tiltable) lay system with a 550-tonne top tension capacity is permanently installed for the deployment of a range of flexible products with a diameter of 50-650mm. The lay tower can operate at up to 10° from the vertical and is fitted with two wire centralizers and with two tensioners, each with a 275-tonne capacity, that can be retracted clear of the firing line. The pipelaying systems are delivered by Huisman.
