Bibby HydroMap Extends Hollandse Kust Zuid UXO Hunt

Bibby HydroMap has kicked off UXO survey operations on the 760MW Hollandse Kust Zuid (HKZ) Wind Farm Zone Sites III & IV on behalf of Vattenfall.

The second UXO survey for the UK-based seabed survey company on the Hollandse Kust Zuid Wind Farm Zone comes after Vattenfall was announced as the winner of the site with a subsidy free bid in July 2019, with construction scheduled for 2022.

Bibby HydroMap have been operational on Hollandse Kust Zuid (HKZ) Wind Farm Zone Sites I & II since March 2019, and the new project follows a similar multi-vessel approach which proved effective on the initial UXO campaign.

Bibby Tethra and Bibby Athena will together acquire over 5,000-line km of high-density magnetometer, side scan sonar, multibeam echosounder and parametric sub-bottom data over the Dutch wind farms. Both vessels will be equipped with a comparable suite of sensors, including dual EIVA ScanFish ROTVs each accommodating four magnetometers designed to provide a dense magnetometer dataset across key locations of the site.

Bibby HydroMap’s recent charter of SeaZip Fix will also aid acquisition across the sites acquiring ultra-high-resolution seismic data over the Dutch sites, providing key information to inform the design and construction of the site.

“We are very pleased to continue our work with Vattenfall on the Hollandse Kust Zuid Wind Farm Zones III & IV and look forward to bringing our experience from working on HKZ I & II into this new project,” says Bibby HydroMap Project Manager Graham Willis.
