Seminar Location
Estrel Berlin, Convention Center
Seminar Timing
08 April 2024

Course Content

1 Onshore and Offshore Pipelines

1.1 Terminologies (piggable vs. unpiggable, challenging and difficult to inspect)

1.2 Scenarios (Accessibility, Is external inspection an option?)

  • Onshore scenarios (CUI, external sheeting, Casings, Materials)
  • Offshore scenarios - Riser – (Static Riser, Catenary Risers, Flexible Risers) - Flowlines and unpiggable subsea pipelines

2 Methods of Inspection

2.1 Inspection Technology

  • Electromagnetic Technology (MEC, PEC, Eddy Current, etc.)
  • UT Technology (TOFD, EMAT, etc.)
  • Others (Radiography, optical,...)
2.2 Operation of inspection tools
  • Deployment of external inspection equipment Offshore and Onshore
  • Internal inspection using - Crawler, How to propel, How to get back - Tethered tools
  • External Inspection, How to get through the coating? How to scan long distances
3 Preparation
  • Planning (Who is involved, What to do at what time)
  • Cleaning (Internal vs. External Cleaning)
  • Deployment (LARS, Navigation, etc)

4 Inspection Solutions

4.1 Actual Solutions of various vendors

Target Group

No special prerequisites, but technical understanding. Target Group: Onshore and Offshore Integrity Engineers working with Operators, Integrity Consultants, Service Providers and Classification/Certification Bodies.


Konrad Reber studied physics at the University of Mainz. In a Ph.D. thesis at the material science department of the University of Erlangen, he worked in the field of magnetic materials. At Pipetronix he was responsible for the development of data analysis algorithms for the application to MFL-pipeline inspections. This included methods of artificial intelligence for analysis automation. Later he also became responsible for the magnetic design of MFL-inspection pigs. After changing to NDT Systems & Services he continued to work in the field of in-line inspection and broadened his focus to include topics of defect assessment and general comparison methods of different inspection tools. Between 2006 and 2008 he was with TUVRheinland as an expert within the Pipeline Technology Group. He was responsible for international projects on pipeline integrity and pipeline certification. Since 2008 he is head of research and development for the Innospection Group. The department is responsible for designing new inspection equipment of the Oil and Gas industry. The focus is on- and offshore applications of the eddy current technology. He is busy in delivering speeches on conferences and is a trainer in various courses on pipeline inspection.
