ClampOn

ClampOn's CUI metering solution allows operators to measure water ingress in the insulation and corrosion along the pipe using permanent microwave antenna arrays installed strategically along the pipeline. Portable data analysers are connected to the permanent antenna arrays for periodic metering and trending. This solution provides effective and accurate measurement of water ingress and corrosion residue, and information about its location along the pipework. 

The ClampOn Subsea SEM is an ultrasonic instrument designed to measure wall thickness loss in pipes over a defined area. It uses active ultrasound and exploits the properties of Acoustic Guided Lamb Waves to detect the changes in wall thickness relative to reference values obtained during the installation of the system. Up to 16 transducers transmit and recieve signals to and from each other to form a grid of signal paths over a defined area, and this is used to monitor any changes in pipe wall thickness. Using the principles of tomography, both the point at which the corrosion and erosion takes place and the actual wall thicness can be measured.

The unique, patented ClampOn DSP Particle Monitor provides operators focusing on sand mangement and corrosion-erosion issues with even more accurate information than previously available. The ClampOn DSP Particle Monitor measures sand/particles through passive ultrasonic technology; it detects the ultrasonic signal that is generated by particles impacting on the inside of the pipe wall, just after the bend where the sensor is located. The instrument has onboard Digital Signal Processing (DSP) for analyzing of the data picked up by the instrument. Measurement is done in real time and results are continuously displayed on the control PC/System, giving the operator immediate and reliable data when a well starts producing sand.
