Difficult to Inspect Pipelines

Registration Deadline
31 March 2025
Seminar Location
Estrel Berlin, Congress Center
Seminar Timing
05 May 2025, 09:00 - 17:00


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



Before your training on the begins, ROSEN's Competence Club, the premier learning and collaboration platform for the pipeline industry, is available for your use at no additional cost. This platform provides four complimentary pre-seminar e-learns that are designed to support you in acquiring the prerequisite knowledge for the course and enhancing your awareness level skillset. The e-learn training can be completed at your own pace and at a time that is convenient for you.


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 with a focus on Solid State Physics. In a Ph.D. thesis at the material science department of the University of Erlangen, he worked in the field of magnetic materials, in particular the measurement of material parameters using magnetic stray flux methods. At Pipetronix (now part of Baker-Hughes) he was responsible for the development of data analysis algorithms for the application to MFL-pipeline inspections. Later he also became responsible for the magnetic design of MFL-inspection pigs. After changing to NDT Systems & Services (now NDT Global) 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. Starting 2008 he was head of research and development for the Innospection Group. The department was responsible for designing new inspection equipment for the Oil and Gas industry. He continued this position for Innetiqs in 2022. His focus is on the development and refinement of testing technologies with applications for underwater or otherwise difficult to inspect structures. He is busy in delivering speeches on conferences and is a trainer in various courses on pipeline inspection.
