New in-line pipeline inspection tool helps cut pigging costs

A new in-line pipeline inspection tool can help reduce pigging costs by as much as 50% while improving data quality.

The MFLCal in-line inspection tool is a single system that acquires high-resolution metal loss (magnetic flux leakage) and caliper data sets simultaneously.

Conventional pipeline in-line inspections often consist of two steps. A caliper tool is first run to "prove-up" the pipeline bore and then the MFL inspection tool is run, the firm points out. The new MFLCal tool's ability to pass bore restrictions more severe than most existing state-of-the-art caliper pigs has largely eliminated the need for traditional bore prove-up by stand-alone caliper, the firm says.

The MFLCal tool provides high-resolution integrated metal loss/mechanical damage information. Simultaneous review and reporting of MFL and caliper data helps reduce the potential for error, improves characterization of pipeline anomalies, and helps ensure cost-efficient remediation.

The MFLCal tool offers pipeline friendly attributes of improved bore-passing capability (25% of OD in most cases), 1.5D bend (back-to-back) capability, shorter tool length, and extended run times, resulting in reduced pigging costs.
