Offshore survey work ramps up at Awel y Môr OWF site After UK CfD award
What happened
RWE and contractors Geo and TGS have started geophysical and geotechnical surveys at the Awel y Môr offshore wind site. The work covers the 78‑square‑kilometre array area and includes CPT and vibrocore sampling, with survey outputs feeding design refinements that precede onshore enabling works. Watch whether survey data accelerates FID timing or forces earlier contractor mobilisation for marine works
Buyer takeaway
Treat survey award as an operational mobilisation event: vessels and CPT rigs block calendars and suppliers will price hold costs and short quote validity
Cost / money
Expect dayrate and mobilisation pass‑throughs to be explicit in bids; short notice bookings can raise short‑term costs
Supplier / commercial
Survey contractors can insist on deposit or hold fees for vessel bookings and may narrow quote validity windows
Safety / operations
Marine survey work increases HSE needs: verify contractor safety case, CPT exclusion zones and SAR arrangements before mobilisation
What to watch
Watch whether survey outputs move the project to design refinements that trigger accelerated onshore civils or cable procurement
Key facts
- 78‑square‑kilometre array area
- Two vessels deployed including a heavy‑duty CPT rig (GeoScope II)
- Onshore construction and cable works sequenced after survey and design refinements

Geo is undertaking cone penetration testing (CPT) and vibrocore sampling to assess seabed conditions. The company will deploy two vessels, including the newly built heavy-duty CPT rig GeoScope II, which will be used in the wind farm’s array area
