Croon was the electrical system integrator and installation contractor for this new build project at IHC Merwede. The Seven Waves is a vessel with high-end technology. Building a vessel of this kind requires technological knowhow and experience in building such a complex vessel.
The Seven Waves has an overall length of 146 meters, a beam of 30 meters and a Class-2 dynamic positioning system. The vessel is equipped with a vertical lay system – with 550t top tension capacity – and twin ROVs. She is fitted with two under deck storage carousels, with a capacity for 2,500t and 1,500t of product respectively. The lay tower can operate at an angel of up to 10º and is fitted with: two tensioners, each with a 275t capacity, which can both be retracted clear of the firing ling: and two wire centralizers.
This pipe laying vessel will be used to develop deep-sea oilfields of up to 2,500 meters off the coast of Brazil on behalf of Petrobras.
The Seven Waves is the fifth vessel contracted by Subsea 7 to IHC Merwede’s Offshore division in the Netherlands as a sister to the Seven Oceans, Seven Pacific, Seven Atlantic and Seven Seas.
