The ClampOn Subsea Particle Monitor is a non-intrusive instrument using passive acoustic and ultrasonic technology. It detects the amount of sand/particles passing through the inside of the pipe. The instrument has onboard Digital Signal Processing (DSP) for analysing of the collected data and sends real-time results to control system, giving the operator immediate warning if sand is being produced.
It is designed for depths to 3000 meters and has full redundancy, for high reliability through seasons with reduced access. Operators are using particle monitors widely to increase production rate by finding a maximum sand free rate. By monitoring and evaluating the data in real-time, the operator can make immediate decisions to ensure safe production.
