Inspection services

PMC provide a wide range of pipeline and asset inspection services such as visual inspection, corrosion measurement, corrosion rectification along with non-destructive testing, hydrostatic testing, radiography and phased array.


PMC has also invested in a number of 3D laser scanners which will eventually replace the traditional P11 inspection.
The hand held laser scanner is a system for increasing the efficiency of pipeline damage measurements. Its use improves safety of technicians by reducing the time spent in excavations and it also improves the reporting of pipeline damage/defect condition.

Aerial surveys

It's a HSE requirement to inspect gas pipeline routes aerially every 14 days. Which is why our team is in the air all year round, conducting aerial surveys to detect any activity on the ground that may be a threat to the pipeline - whether that's building work, excavation or something out of the ordinary.

We operate a fleet of helicopters with a crew of ex-army pilots and observers - spotters with the career training, skills and experience to step into the role. It's a job neither drones nor fixed-wing craft can do efficiently or cost-effectively.

Keeping the gas flowing

That's why we fly. Since 1998, we've logged nearly 300,000 sightings of activities on the transmission and distribution pipelines across the UK. We report them on the SRP surveillance reporting system, for ground staff to evaluate. The networks must deal with the issue within 24 hours.

We've also made nearly 3,000 sightings we categorise as 'immediate' - that means, we have spotted significant activity that National Grid had been unaware of, which would have caused damage to the pipeline and halted the gas supply to an area - or worse. We report these by phone as well as SRP, and they must be dealt with within the hour. We also have the authority to land and instruct people to stop work if the potential danger is serious enough - something we've had to do twice.
