Condition Surveys
Subsea cable and pipeline are critical commercial assets and require routine inspection for fatigue, bending and external damage, scour and sediment migration. Suspended cables and pipelines in high current areas can be prone to early fatigue from "strumming".
TerraSond uses multibeam and side scan sonar systems for sub aqueous inspection of underwater cables and pipelines. The high resolution imagery obtained allows our staff to discover and interpret problem areas.
