Cable Route Landing

With the growth of offshore wind farms and international subsea cable networks, the demand for accurate cable route surveys has never been higher. SAND brings extensive experience in both shallow and deepwater operations, combining land and marine data to deliver a comprehensive understanding of cable landing conditions. Our surveys help clients optimise the design, dredging, installation, conservation and decommissioning of subsea cables by providing:

  • Detailed bathymetric mapping
  • Subsurface geological imaging & interpretation
  • Identifying potential obstructions & UXO
  • Locating pre-existing infrastructure

Sensor Type

MBES, TVG, SSS, SBP, with the addition Magnetic Drone Survey  (UAVs)
