GRID
The OnlinE Gauging Run Integrity Data (GRID) System allows the user to determine the position of a defect along a subsea pipeline.
- A simple pig fitted with a gauge plate and GRID transducer is moved thorugh a pipline
- The GRID transducer is monitored from up to 1km range using an acoustic receiver and GRID decoder.
- Signals the time the defect was detected and using the pumping data an approximate position of the defect can be predicted.
