It is not an inspection device but provides true real-time information that allows corrective actions to prevent or limit corrosion within the process. Fully tested and qualified, the RPCM TM spool is an established technology with a proven track record capable of the most demanding HT/HP deepwater service. The system can be rated to : 1035 bar (15,000psi) 180 degrees C (350 deg F) and 3050m (10,000 ft) water depth. The RPCM™ spool is an in-line, piggable, monitor for pipelines and flow lines giving full circumferential corrosion rate measurement plus pressure and temperature. The exceptional resolution of the embedded CEION® metal loss measurement technology makes RPCMTM a uniquely effective tool for pipeline integrity applications. When the RPCM TM is combined with modelling, the two work together to provide true real-time flow assurance integrity. Strategically placed monitoring, combined with modelling, results in full visualisation of the corrosion profile and other flow assurance variables along the line. The data generated from monitoring systems can be employed to provide on-going refinement of the models and predictive forecasting. User benefits include: - Greater system integrity, reduced maintenance and no unplanned shutdowns - Justification to employ carbon steel and corrosion inhibition in place of corrosion resistant alloys - Visibility to ensure high corrosion inhibitor availability and optimised dosing - Potential to employ reduced corrosion allowances - Potential for reduced pigging facilities and pigging runs - Alarming of process upsets and visible response to corrective actions - Extended facility life Suggested locations: * - Topside pipelines - Production Risers - Subsea flowlines - Subsea pipelines - Onshore pipelines * For single point subsea pipeline corrosion monitoring please refer to our PTEC product information

This inner spool array is contained within an outer pressure retaining envelope and is connected to the external instrumentati on via a high integrity HT/HP penetrator assembly. The dual redundant instrumentation can be ROV retrievable and...

Communications are flexible and interfacing simple. Once on location the unit is connected via a jumper cable to the SCM using underwater mateable connectors. Electronics pods are low power consumers Performance Resolution is dependent on pipeline diameter and sensing element wall thickness....
