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 HydroMapā€™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.

ā€œWe 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,ā€ says Bibby HydroMap Project Manager Graham Willis.
