Live Pipe Access / CCTV Surveys

To minimise impact on pumping schedules and where possible to eliminate impact altogether, we have patented technology which enables PIV’s to be launched for live pressurised pipe surveys.

On a recent project for Thames Water/Optimise, we launched a PIV with CCTV and profiling sonar via a 20m deep shaft into a live potable water main operating at circa 8-bar. Due to operational constraints the PIV was launched vertically down the shaft, where it turned through 90deg at the base of the shaft to enter the tunnel to carry out a 2.7km survey.

A custom built PIV launch cage and combined cable roller assembly eliminated cable abrasion at the point where the vertical face of the shaft meets the crown of the tunnel.

We have launched PIV’s into pipes, tunnels, aqueducts, siphons and outfalls from underground chambers, header tanks, shafts, reservoirs, gate valves and custom built pressure chambers.
