Tutorial # 9: Pipeline In-line Inspection – Validation and Use of Results
Presenter: Phillip Nidd, Dynamic Risk
Description:
This tutorial will address what companies need to do after the data is received from the ILI vendor. The checks that should be done to determine whether the inspections meet the contractual quality communicated by the vendor (ex. +- 10%, 80% of the time). In addition to the analysis of reporting quality, the session will also discuss how to use tool tolerance in making decisions based on tool data (ex. Re-inspection intervals). Issues such as probability of detection and probability of indication will also be covered.
Tutorial # 10: External Corrosion Basics
Presenter: Robert Worthingham, Worthingham Professional Services Inc.
Description:
This tutorial will discuss the primary methods of external corrosion control for pipelines. A brief summary of the science of external corrosion will be provided followed by theory and practical aspects of pipeline coatings and cathodic protection. Both plant and field applied coating application concepts will be discussed. Conventional impressed current cathodic protection systems and associated monitoring will be presented.
Tutorial # 11: SCADA / Leak Detection
Presenters: Mike Yoon
Bruce Warren
Description:
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.

Tutorial # 14: Advancing from Integrity Management Programs to Integrity Management Systems
Presenter: Rafael G. Mora
Description:
In the early 21st century, Integrity Management Program (IMP) approach was formally introduced in North American pipeline transmission companies via regulations (i.e. NEB OPR-99 Canada and US DOT 49 CFR 195-2000, 192-2003) and industry consensus standards (e.g. API 1160-2001, ASME B31.8S-2001). However, the need for continuously improving the IMP effectiveness in a systemic way has led regulators and industry to advance towards to Integrity Management Systems (IMS).
The purpose of this tutorial is to transfer technical knowledge and experience on the historical evolution, purpose, elements and referenced standards, interrelations and strategies for advancing from Integrity Management Programs to Integrity Management Systems.
The attendees will interactively participate in group activities for understanding the differences and interrelations between universal IMP and IMS elements as described by latest industry standards (API, ASME, CSA and ISO) and North American regulations as well as developing their own strategies for implementation.
