Intelligent solutions for crack inspections of challenging offshore pipelines, latest developments and case study

Pipeline system integrity has become increasingly important to pipeline operators. Accurate measurement and evaluation of the physical condition of oil and gas pipelines is critical to effective integrity management, as well as to assure pipeline safety.

Typically, inline inspection is carried out for the detection and sizing of geometry-, corrosion- and cracking defects. However, there are still many pipeline systems offshore which were never designed and built for conventional ILI tools and modifications would be extremely expensive.

KTN AS, Bergen, Norway, a company of the Rosen Group, has developed during the last 19 years a flexible tethered, bidi, self-propelled inspection tool for challenging pipelines which can combine technologies for measurement of the pipeline geometry (dents, ovalities, roofing etc.), wall thickness / corrosion / laminations, crack detection and precise crack sizing. Technologies used are piezo UT pulse echo vertical- and angular beam, phased array, TOFD, high resolution camera, grinding machine and eddy current based technologies for dry lines. This tool is tailor made for every inspection and cannot only detect axial cracks (SCC, fatigue crack etc.) but cracks in all directions (girth weld cracks, etc.). The crack depth and profile is measured quantitatively. Data collection is done on the way in and out, the results are visible in real-time.

The paper will explain the technologies used and the specifications achieved and will shortly give the results of successful projects done offshore as detection and accurate sizing of girth weld cracks, circumferential cracks at anodes and axial cracks in and along longseam welds.
