Cable Route Studies

It is generally accepted that any time spent on the Cable Route Study will result in significant cost savings for the burial survey, installation and operation of the project.

The cable route study should cover all aspects concerning the cable route to the most accurate level possible prior to conducting a survey. Whilst the extent of the survey is dependent upon the size of the project and potential threats to the cable, the study would typically comprise:

Identification of Hazards
- e.g. fishing and shipping activity

Submarine Route Environment
- e.g. Geology, bathymetry, tides and currents

Preliminary cable engineering
- e.g. Route position list, cable burial & protection

Identification of permitting activities
- e.g. Cable route survey and Installation

Survey recommendations
- e.g. Geophysical, Geotechnical and Burial assessment

We use ArcView and Integraph's Geomedia software to fully utilise the data obtained in the route study in a GIS enviroment, since SEtech are not looking for a lead into survey work, our independent report is driven by the engineering requirements of the route rather than its survey potential.

Survey Specification & Management

The survey is often on the critical path for installation. Timescales can often be reduced by ensuring the cable route study is as detailed as possible, and by careful specification of the survey. The repetition of standard specifications and work scopes, without assessing the project specific requirements can result in inappropriate and occasionally inadequate methodologies.

SEtech advise on the selection and specification of geotechnical investigation techniques for all aspects of the survey including shore ends. We also provide Quality Control services.
