TRAC utilised Silverwing’s RMS2 450 corrosion mapping system as the primary inspection tool which performed admirably, working continuously during the 12 to 14 hour shifts. The majority of the inspection was conducted at a 5 x 5 mm scan resolution with any areas of concern scanned in more details at a 1 x 1 mm resolution. The dome ends were scanned using the RMS2 300 which is designed for smaller areas with the advantage of pivoting tractor motors allowing it to scan various shapes.
A total of 260 scans were collected using the RMS2, an average of 2 metres long. As you can imagine that is a lot of data to analyse and report, which can sometimes take longer than the actual inspection time.
