Reorganization of ptc 2020 because of COVID-19 and announcement of the 1st Virtual Pipeline Summit (latest update: 3 June 2020)
Every pipeline operator is looking for a means to improve on OPEX in order to streamline his operations to the varying oil & gas market. To this end, less conservative assessment approaches for corroded pipelines, detecting even the smallest pinhole features, are an optimum solution. Such approaches provide detection and assessment precision that will ultimately save cost by minimizing field verifications while ensuring maximum pipeline safety.
With RoCorr MFL-A Ultra, ROSEN has made a solution available that features
- a circumferential MFL-A resolution of 1.6mm, matching the resolution of state-of-the-art in-the-ditch validation equipment such as Matrix UT and 3D Laser scanners;
- ILI tools with twin-suspension sensor housings and a double MFL sensor ring, eliminating the ‘blind spot’ around girth welds while running in common MFL operating conditions; and
- machine-learning algorithms based on 3D contours of real defects, delivering unparalleled feature-detection/sizing capabilities and reducing ‘human factor’ impact
to deliver precise assessment results within standard reporting times.
Using data examples from recent pipeline inspections and subsequent field verifications, the authors of this paper demonstrate how the RoCorr MFL-A Ultra service is instrumental in the assessment of
- small pinhole features,
- complex corrosion, and
- girth-weld related defects
by delivering more realistic ERF calculations with the goal of reducing field verification costs.
