Geotech Survey Start

In June 2023, Belgian survey company GEOxyz began work on the Nederwiek 3 (NW3) export cable route under a contract from TenneT covering both geophysical and geotechnical route surveys from Stellendam to Geertruidenberg, with optional offshore and nearshore sections near the wind farm. GEOxyz had mobilised dedicated survey vessels Geosurveyor VIII and Geosurveyor V for the inland and nearshore parts of the route, with other assets scheduled for offshore, ultra‑shallow and land sections. The geotechnical scope includes seabed investigations with a required penetration depth of around 10 m for geotechnical sampling, using a novel marine sampling technique to obtain high‑quality soil samples. Data from these surveys will be used to build a geological model of the cable corridor and feed into a Burial Assessment Study to inform cable design and installation methodology.
