Rovco has signed a contract with Van Oord to perform subsea investigation works on the 759MW Dutch offshore wind farm Hollandse Kust Noord (HKN).
The company has been contracted to carry out an unexploded ordnance (UXO) investigation and identification campaign, as well as survey work across nominated locations of the offshore wind project with the removal of any potential debris objects at the site which may impede foundation and cable installation works.
The project will use the DP2 vessels Glomar Wave and VOS Star across two phases, deploying Rovco’s Seaeye Leopard WROV fitted with SubSLAM X2 technology and PanGeo Subsea’s Sub-Bottom Imager, to identify subsurface targets and generate full 3D models of UXO items in situ and in real-time during investigation.
CrossWind, a joint venture between Shell and Eneco, received the permit for the Dutch offshore wind farm in 2020, and selected Van Oord as the balance of plant contractor for the development.
CrossWind plans to have the wind farm, located 18.5 km off the coast of the Netherlands, operational by 2023.
“We are looking forward to working with our partner Rovco on the Hollandse Kust Noord project in the Netherlands.
“The UXO investigation and identification campaign is an important step towards delivery of the offshore wind farm.
“By making use of the sub-bottom imager technique first, followed by physical approach of remaining potential UXO targets, Rovco provides a state-of-the-art solution which increases the efficiency of the project”, said Roeland Ris, project director at Van Oord.
