The requirement for real-time corrosion monitoring devices is becoming increasingly important for sub sea oil and gas pipeline systems with longer tiebacks and highly corrosive process environments now typical for new deepwater installations.

The RPCM™ is a flow-through device designed to address this requirement. It provides high resolution full circumference metal loss and temperature measurements. This paper describes the technology and key features of the RPCM™, including enhancements to the product capability allowing a wider more holistic flow assurance and integrity monitoring service, using measurement techniques such as conductivity, passive acoustics, and Venturi measurement.
