Claxton offer a range of pipeline coating removal (PCR) systems powered by high pressure (hp) and ultra-high pressure (UHP) water, designed to remove concrete and other protective coating from pipelines.

The system is capable of both linear and circumferential passes with only diver or ROV intervention necessary to cut the re-enforced bars exposed by the coating removal process.

Claxton’s PCR technology is capable of removing coating on pipelines ranging from 100 – 1200mm (4-48in) outside diameter, with systems designed to remove a 360˚ section of coating up to 1m in length. This is achieved by manipulating the jetting carriage using linear and circumferential movements, hydraulically controlled with fly by wire technology.

The PCR systems are fitted with rotating multi-jet heads to remove various coating types at the optimum rate. The electro hydraulic supply and control can be operated from the surface or via the ROV subsea. All monitoring and adjustments are controlled via our in house designed software.

High pressure multiple jet nozzles produce an ultrasonic, inspection-ready surface finish to SA 2.0 standard, without the need for further grit blast cleaning or wire brushing.

Remove any type of protective coating

Suitable for pipeline inspection and repair, tie in, hot tap and emergency pipeline repair, the PCR tool can remove any type of protective coating from fusion bonded epoxy (FBE), concrete weight coat and single unit polyurethane (SPU), to bitumen and coal tar enamel, at water depths up to 600m. High pressure multiple jet nozzles produce an ultrasonic, inspection-ready surface finish to SA 2.0 standard, without the need for further grit blast cleaning or wire brushing.

Using fly-by-wire technology to remotely control the tool via a laptop and pipeline crawling capabilities to reduce the number of lifting operations required to reposition the tool, the PCR system can remove a standard protective coating on a 12” pipeline in an industry leading time of four hours.
