At this year’s Pipeline Pigging & Integrity Management Conference in Houston, Texas, the ROSEN Group will introduce a disruptive technological innovation, breaking the current boundaries of MFL technology. This technology enables a true understanding of what is in the ground by providing laser-like 3D metal loss profiles derived from MFL data, with clear benefits for operators: visualization of the true metal loss shape, robust information for maintenance optimization, and integrity confirmation.

The most widely deployed in-line inspection (ILI) tools utilize the robust and proven magnetic flux leakage (MFL) technology. Applying electro-magnetic principles, MFL tools are particularly well suited for the inspection of gas pipelines. Determining the true mechanical integrity of a pipeline requires a good understanding of any metal loss potentially present, ideally to see what is really in the ground. It is widely accepted that advanced integrity assessments benefit from knowledge about the true defect shape. In case of corrosion, this helps to understand the morphology of a corrosion feature and provides a better understanding of the corrosion behavior, especially in the case of complex shape corrosion or interacting metal loss features. Precise knowledge of the true shape also enhances sizing accuracy.

Unfortunately, 3D profiling has not been available for ILI tools utilizing MFL until now.

As a technology leader and innovator, ROSEN is now breaking the boundaries by taking MFL technology to the next level. Called Deep Field Analyze, this new technology enhances the level of information that is implicitly available in high-resolution MFL data and collected during ILI runs. High-quality data from axial and circumferential MFL inspections is used and processed to provide laser-like 3D profiles of a metal loss feature, thus visualizing the true shape of any corrosion or gouging, even before a dig up.

This truly unprecedented approach breaks the boundaries, taking us beyond traditional boxing focused on feature length and depth.

This technology and evaluation method delivers:

  1. True metal loss shape: highest confidence in data interpretation
  2. Maintenance optimization: dig up prioritization and faster decision-making for future activities
  3. Integrity confirmation: less conservative calculation of safe burst pressure

New and unique to the in-line inspection market, this technology will be incorporated into a new service offering from ROSEN: Virtual−Dig Up
