UK marine outfit Bibby Hydromap has started an unexploded ordnance survey for Vattenfall at the site of the 700MW Hollandse Kust Zuid 1&2 offshore wind farm off the coast of the Netherlands.
Vessels Bibby Tethra (pictured) and Bibby Athena will together acquire over 4,000-line km of high-density magnetometer, side scan sonar, multibeam echosounder and parametric sub-bottom data at the site 22km from shore, the surveyor said.
The company said each vessel is equipped with sensors, including dual EIVA ScanFish ROTVs with four magnetometers.
Bibby Hydromap added that it secured the contract earlier this year following a competitive bid process.
Bibby HydroMap project manager Daniel Jenkins said: “We are delighted to be working with Vattenfall on Hollandse Kust Zuid in 2019 to support their renewable goals.
“Utilising the latest offerings from industry leading suppliers we are able to provide a highly effective and efficient UXO survey methodology, applicable to even the most environmentally challenging of sites.”
Hollandse Kust Zuid 1&2 is scheduled for completion in 2022.
