Landing Point Assessment

Using the wealth of experience and data available to OceanIQ, married with the knowledge from those installing and maintaining submarine cable systems from the wider Global Marine Group, we deliver detailed assessments about a specific landing location addressing issues so the optimum location can be sourced.

Balancing the marine and land-based requirements of submarine cable systems

Deciding upon the location where a submarine cable system meets the land is crucial. It is important to minimise any conflict with other seabed users, while maximising the security for a new cable. The number of industries operating offshore continues to increase dramatically, and with this – whilst our oceans remain vast in space – usable areas are becoming increasingly limited and there is much competition. It is therefore essential that a thorough assessment is undertaken, and, with those findings, imperative that our route engineers carefully balance all known aspects to position a cable route in the ideal position to prevent potential cable damage.

If you would benefit from a detailed analysis of a specific location, please get in touch where one of our experts can share our learning gained from over 100+ landing studies completed in the last ten years.


Such assessments can include:

  • Research bathymetry, seafloor and shallow seabed lithology, currents, weather, seismology, tides, permits, other seabed users, seabed temperatures, fishing, shipping, and anchoring
  • Identify areas of potential difficulty for survey, installation, and subsequent maintenance.
  • Investigate environmental and cultural aspects relating to the cable route, highlighting relevant marine protected areas, statutes, and regulations of the various authoritative bodies.
  • Identify sources of risk to the cable.
  • Confirm it is suitable for landing a cable and locate any nearby backup options
  • Meet local and/or national authorities to gather detailed information on the permitting requirements for the system
