Route Thermal Surveys

A thermal survey of the proposed cable route is essential to evaluate the thermal and geotechnical properties of the subsurface or sub bottom soils. This includes the measurement of ambient temperature and in-situ thermal resistivity at select locations and depths. Industry standard soil boring/sampling procedures are followed in accordance with the ASTM. This is the first step in a cable system design from Ampacity (cable rating) viewpoint.

Through our experience and expertise, using the state-of-the-art test equipment (Thermal Property Analyzer-TPATM) and accessories (custom-built thermal probes) we provide these services for underground as well as submarine power cable routes.
