Subsea 7’s Seven Waves En Route to Brazil

Subsea 7’s Seven Waves set sail to Brazil for her first job for Petrobras.

The vessel was hired by Petrobras to develop deep-sea oil fields of up to 2,500 meters off the coast of Brazil.

Before the departure Seven Waves was equipped with the 550mt pipelay system and the 400mt offshore mast crane at Huisman’s Schiedam yard.

The 550mt flex-lay system is the highest capacity flex-lay system onboard a pipelay vessel and is designed and built for the installation of flexible pipelines in 3000m water depth.

The tower is tiltable to allow connection of flexible risers to rigid pipelines which are retrieved from the seabed.

The 400mt deepwater crane (up to 3000m) onboad the Seven Waves is equipped with a deepwater lowering system and an active heave compensation system to counter-act the vessel’s heaving motion when landing a load on the seabed.

The vessel was built by IHC Merwede.
