Damen completes work on dredging and jack up vessels

Damen Shiprepair & Conversion (DSC) has recently completed works in Vlissingen and Brest on two major vessels in the fleet of dredging and marine construction specialist Jan de Nul Group.

One of these is Vole au vent, a 140m jack-up vessel built specifically for the installation of the latest generation of offshore wind turbines.

The other is the trailing suction hopper dredger Leiv Eiriksson. Both vessels are among the largest in their classes, anywhere in the world.

The jack-up vessel Vole au vent arrived at Damen Shiprepair Vlissingen (DSVI) late in 2016 having spent the summer working on the Nobelwind offshore wind farm off the coast of Belgium.

She came to DSVl for modifications necessary for her second phase on the Nobelwind project; the installation of the WTG scope.

These required the demobilisation of her existing equipment used for the foundation campaign and the installation of a new configuration  for the WTG installation phase.

Over the course of two weeks, her 3,400m² main deck was cleared of equipment and temporary structures and restored to its clean, completely flush layout. This allows her to accommodate wind turbine installation equipment and components, towers and blades for its next deployment off the coast of Belgium.

On 16 February 2017 Jan de Nul Group’s 223m trailing suction hopper dredger Leiv Eiriksson departed from Damen Shiprepair Brest after a three-week maintenance programme. This followed an 18-month assignment on a large-scale land reclamation project in Nigeria.

The works included replacement of the 1700mm discharge lines, changing the power cables for the suction arms, fresh paintwork, the assisting of specialist sub-contractors with steering gear, propulsion and thruster repairs, valve repairs and minor steel works. With a hopper volume of 46,000m³ and a DWT of 78,500 tonnes, Leiv Eiriksson is one of the world’s largest dredgers.
