Bibby HydroMap Stays on Hollandse Kust Zuid

Vattenfall has awarded Bibby HydroMap second unexploded ordnance (UXO) survey on the Hollandse Kust Zuid wind farm zone in the Dutch North Sea.

The UK-based seabed survey company has already commenced operations on the 760MW Hollandse Kust Zuid (HKZ) III & IV.

The news 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 has been operational on Hollandse Kust Zuid (HKZ) I & II since March 2019, and the new project follows a similar multi-vessel approach. 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.

”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,” Bibby HydroMap Project Manager Graham Willis.
