Technical Details

The rugged mechanical design features an array of independent spring-loaded sensing arms coupled to high-resolution sensors. The dual wheels on each arm ensure maximum coverage of the inner surface of the pipe. Distance measurement is provided by dual odometer wheels with “self cleaning” features to minimize slippage. The electronics in the MultiCal 360 include the latest “flash memory” data storage as well as USB communications to the host PC ensuring reliable.

The Weatherford proprietary visualization and analysis software package, providing a detailed database of anomalies, pipeline features, and geometry anomalies—allows data to be viewed in various formats.

The software, anomaly database and analysis report (generated by the analysis center) are then compiled to form a comprehensive final report to document the integrity of the pipeline.
