Spain’s Sestaoarra La Naval shipyard has delivered the fallpipe vessel Simon Stevin to the Belgian dredging contractor Jan de Nul.
The 32,500t all-electric vessel ship has been designed to deposit rocks on the seabed to fill trenches, cables and pipelines to a maximum depth of 1,700m.
Built under BV class with DP2 notation, the vessel features five diesel driven generator sets, four propulsion thrusters and two bow thrusters.
The Simon Stevin is capable of dumping 2,000t of rock per hour, can process boulders with a diameter up to 400mm and is also suitable for deep sea mining operations including recovery of minerals from the seabed.
The ship was built in 26 months, with the steel cut in December 2007, the keel laid in April 2008 and the vessel launched in March 2009.
