Pipelines can be put at risk if the ground around them, the pipeline right of way, moves.
It may be a small, one-off settlement.
It may be the precursor of a more serious event, evidence of an earth tremor, erosion, or a landslide. Knowing where, and when means that the site can be checked and, if necessary, mitigation measures put in place.
fibrisTerre’s 80 km distance range means that, with a fiber optic cable running alongside the pipeline, a single instrument can monitor continuously for ground movement events along 80 km. With the aid of an optical switch, this distance can be doubled.
Distributed fiber optic strain sensing detects small ground movement events, helping operators to respond quickly. And false alarms are rare.
