A dedicated marine hydrographic survey along the route corridor, as outlined in the Desktop Study, is used to approve the route and to gather the detailed information which enables the final route engineering to be undertaken.
Using the most advanced techniques and equipment, the marine survey typically uses geophysical tools such as echosounders, sonar, sub-bottom profilers, and magnetometers, combined with geotechnical sampling to provide a comprehensive set of data which is charted and incorporated into our cable routing GIS software.
We increasingly use aerial drones and autonomous surface vessels which can bring cost and technical advantages.
The survey data is interpreted and used to complete burial assessments which help determine the best burial tools and cable protection measures for the system, combined with the knowledge gained from the Desktop Study on the likely sources and nature of risks to the cable.
On-site OceanIQ survey representatives ensure the survey works meet the survey specification, to undertake in field routing decisions and engineering when required.
