3. Environmental Factors: Pipeline Lifecycle Cancelled
4. Pipeline Materials
Presenter: Julia Race (Newcastle University)
This tutorial will provide an overview of the materials used in onshore and offshore transmission pipelines and flowlines and detail the rationale behind their selection. At the end of the tutorial, attendees will be equipped with an understanding of how material selection relates to pipeline performance. The tutorial will:
- introduce the differences between pipe grades (API 5L) and the specification of the key properties of pipe materials (strength, toughness, weldability).
- detail the history of steelmaking developments and their influence on steel properties (i.e. semi killed vs fully killed, heat treatments, microalloying and clean steels for sour service).
- describe the main features of pipe production and manufacture (SAW – longitudinal and spiral welded, seamless and ERW).
- describe the processes involved in pipeline welding, weld cracking and the effects of heat affected zones.
- demonstrate how the material selected affects the internal and external corrosion, stress corrosion cracking, sour cracking and fatigue susceptibility of the pipeline.
- describe how materials fail and the process of failure investigation, e.g. identifying brittle and ductile failure, fatigue cracking, stress corrosion cracking, microbial cracking.
The tutorial will be interactive and will include a mix of lectures (illustrated with examples), group case studies and videos

9. Pipeline In-line Inspection – Validation and Use of Results
Presenters: Patrick Vieth & Tom Bubenik (CC Technologies)
This overview will include ILI technologies, capabilities, limitations, industry recommended practices and processes and procedures for ILI programs. The focus of this session will be on how to manage the ILI data after it is received from the vendor. This includes the evaluation, validation and re-calibration of results.
10. SCADA / Leak Detection
Presenter: Mike Yoon (Yoon Consulting) & Bruce Warren (BCTgroup)
The tutorial will provide an overview of pipeline SCADA systems and leak detection systems for hydrocarbon liquids. The SCADA overview will begin at field end-point devices and follow the processing of this information through the facility PLC/RTU through the communication system to the SCADA host. The tutorial may look at data accuracy, data formats, data security, polling methodologies, communication system alternatives and provide a description of the basic functions within the SCADA host. Leak detection will discuss material balance methods, with and without line pack compensation, and will discuss basic principles as they relate to instrumentation selection and SCADA system design, together with a discussion on leak detect ability and uncertainty.
