The GRID™ System OEL’s next generation GRID™ system understood to be the first of its kind in the world is designed to detect and log multiple defects in a pipeline during pre-commissioning gauging operations and transmit the data through the pipe wall to a monitoring receiver over a range of up to 1km. GRID™ is installed on standard bi-directional utility pigs for flooding, cleaning, gauging and testing purposes. Data is obtained without the need to recover pigs or receiver heads for manual inspection of gauge plates delivering considerable cost savings in vessel time and manpower. GRID™ is modular and configured to client’s requirements, fitting either or both of 7000 Auto Reset Gauge Fingers (ARGF) or 7001 Break Wire Gauge Plate (BWGP). The system can be supplied with either the 803 or the 1203 GRID™ acoustic transducer.
- 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.
