US-based Weatherford has introduced its MultiCal 360 multi-channel caliper pig. This new in-line inspection tool has been designed to combine multi-channel caliper and the company’s SAAM smart utility pig technologies to provide enhanced resolution and accuracy, for timely and reliable geometry results. A large number of caliper arms and new data-sampling techniques enable the definition of the size, profile, location, and o’clock position of pipeline defects down to 2% (or smaller) of diameter. The tools is also designed to meet new OPS pipeline-integrity-management regulations in the USA.
Suitable for use in hydrocarbon lines from 6-60in, the initial fleet of tools is based in Houston, and deployed by Weatherford’s experienced personnel who provide on-site analysis reports for the identification of critical defects.
