Site Surveys

During the initial planning phase of a project, selecting the proper landing location for the proposed system is paramount. INS specialists assist our clients in determining the best cable landing sites available and review the specific criteria required by our clients to ensure the landing sites selected are both technically and commercially feasible.

  • Outside plant route review & selection

  • Cable station land acquisition

  • Preliminary review of associated hazards

  • Location background information

  • Presence of existing obstructions / cable systems

Desktop Studies

Upon completion of the site survey, a comprehensive desktop study is performed, including records of site history and other documentary data.


Desktop Study Services Include

  • Potential permit requirements

  • Location of existing cables or other potential obstructions

  • Tide/current data

  • Geophysical assessment of the landing locations and cable route

  • Historical weather data

Marine Surveys

After the site survey and desktop study are completed, a detailed marine survey is preformed.

This mapping is critical in determining final cable route alignments and cable specifications.
