What Does Remote Inspection Mean?

A remote inspection, also known as a remote visual inspection, refers to the process of investigating existing pipelines for problems such as cracks, blocks, tree root intrusion, corrosion and other signs of deterioration using video cameras that are inserted into the pipeline. These cameras are capable of transmitting data to monitors either remotely or through cables attached to the device. The camera is controlled by an operator in a portable vehicle at the site of inspection. The closed circuit television (CCTV) camera enables video inspection of pipelines such as stormwater pipes, sewer pipes, industrial pipes, potable water pipes and even culverts.

Once the problems are detected and located, trenchless methods such as mechanical spot repair, cured-in-place pipe (CIPP), sliplining and pipe bursting can be used to rectify the problem.

Trenchlesspedia Explains Remote Inspection

Remote inspection using CCTV cameras mounted on crawlers can also be conducted other reasons. Preliminary inspection is carried out to verify the initial pipeline construction immediately after installation to detect any deficiency prior to submitting for approval by owner. Final inspection is carried out along with the concerned engineer appointed by the municipality prior to submitting for approval to the municipality. Investigatory inspection is carried out to perform condition assessment and also to conduct mapping of utility lines.

Maintenance inspection is carried out to detect problems in the pipeline as mentioned above in order to choose an appropriate trenchless method to carry out repiar and maintenance of pipelines. Remote inspection is a cost saving trenchless technique that prevents digging up or damaging unaffected pipes.
