Technical Group Webinar
A Structural Integrity Technical Group Webinar
Attendees will learn about the implementation of fracture mechanics methods, (Engineering Critical Assessment = ECA), to derive flaw acceptance criteria for pipeline girth welds. In particular, overviews of the main standards applied for this purpose will be discussed, e.g. CSA Z662, API 1104 and DNV-OS-F101/RP-F108. Challenges introduced with the use of ECA will be discussed and the event will be rounded off with presentations on fatigue assessment for offshore risers and future challenges for the use of ECA on pipelines.
This webinar is aimed at materials, welding and NDT engineers, fracture mechanics specialists, pipeline engineers and all others who are interested in pipeline integrity, especially those involved in pipeline construction whether it is onshore or offshore.
Experts from industry and TWI will be presenting on a range of topics:
- Practical Implementation of ECA Based Weld Flaw Acceptance Criteria in Canada, David Horsley, Consultant, Horsley Consulting Ltd.
-
API 1104 Appendix A – Past, Present and Future, Dr Robin Gordon, Senior VP, Microalloying International
-
DNV’s Recommended Approach for Assessing Flaws in Pipeline and Riser Girth Welds – DNV-RP-F108, Steinar Bjerke, Principal Specialist, DNV
-
Challenges Implementing ECA Based Flaw Acceptance Criteria, David Reeves, Senior Engineer Materials and Welding, Nova People AG
- Quantifying Probability of Fatigue Failure in Offshore Risers; an Alternative to the Use of Design Fatigue Factors (DFF), Dr Isabel Hadley, Technology Fellow, TWI Ltd
Presentation co-authored by: Alexandre Galiani Garmbis (Petrobras), Justin Crapps (ExxonMobil)

MEET OUR EXPERT SPEAKERS
David Horsley, Consultant, Horsley Consulting Ltd.
Presentation title: Practical Implementation of ECA Based Weld Flaw Acceptance Criteria in Canada
David Horsley has over 30 years’ experience in the pipeline industry, specializing on materials, welding, and fracture. Much of his time was spent on technology development and implementation. He was chairman of the PRCI Design, Materials and Construction committee for six years, and led the Fracture focus of that committee for many more years. He has served on the CSA pipeline Materials and Design standards committees. David is the author or co-author of over one hundred papers or articles pertaining to pipeline materials, welding, ECA and design.
Dr Robin Gordon, Senior VP, Microalloying International
Presentation title: API 1104 Appendix A – Past, Present and Future
Dr. Robin Gordon has consulted for the Oil and Gas Industry for more than 40 years and is a recognized expert in Engineering Critical Assessment (ECA) and Fracture & Fatigue Design. Dr. Gordon has authored more than 100 papers on the development and application of Fitness-for-Service and Reliability design and assessment methods to offshore structures, pipelines and pressure vessels. He has managed a number of major research projects on pipeline reliability as well as several international Joint Industry Projects on Fracture and Fatigue Design. Dr Gordon is currently involved in a number of research initiatives to develop ECA methods for pipelines that experience large strains during installation or operation and pipelines that operate in sour service.
Steinar Bjerke, Principal Specialist, DNV
Presentation title: DNV’s Recommended Approach for Assessing Flaws in Pipeline and Riser Girth Welds – DNV-RP-F108
Steinar Bjerke has over 24 years of experience in structural integrity analyses, specializing on fracture mechanics analyses, fatigue analyses, failure investigations, and materials testing. Steinar is the author and responsible for DNV-RP-R108 and the fatigue and fracture limit state of DNV-ST-F101.
David Reeves, Senior Engineer Materials and Welding, Nova People AG
Presentation title: Challenges Implementing ECA Based Flaw Acceptance Criteria
David Reeves is the Chair of the Technical Group. David has over 30 years’ experience working in onshore and offshore construction, heavy engineering, and nuclear industries. He started his career with Whessoe Heavy Engineering Ltd in 1976 as a technical apprentice, progressing to Senior Welding Engineer for Onshore Construction in 1985. Since 1991 David has worked in Offshore Oil and Gas occupying a variety of roles for installation contractors, engineering companies and operators.
In all these roles, he has been active in developing weld flaw acceptance criteria for pipelines and steel catenary risers using his knowledge of welding, NDT and engineering critical assessment. He is currently working for Nord Stream2 AG as a senior materials, welding and NDT engineer.
Dr Isabel Hadley, Isabel Hadley, Technology Fellow, TWI Ltd
