21-st century’s society is an “environment of risk,” and the pipeline industry is embedded in this environment.
Hence, it is a must for pipeline operators to know how to create integrity-management plans that minimize the overall costs of pipeline operation and that address the consequences of a possible leak or burst – loss of life and property, pollution, numerous intangible losses – and the civil and criminal liabilities attached to them.
They need to know how to use recently-developed, powerful, and cost-effective tools of risk-based maintenance to their advantage when identifying the best methods for maintaining the structural soundness of transmission pipelines
This unique course presents the full range of methods of risk-based management for pipeline integrity and safety, including the human factor component, and is intended for pipeline professionals at every level.
The methods range from simple and quick qualitative and semi-quantitative assessment methods to more-sophisticated pipeline risk analysis. The course is highly interactive, and takes the form of lectures, workshops, case studies, and discussions. The course is organized in association with the Science and Engineering Center of the Ural Branch of the Russian Academy of Sciences.
Objectives
The course objective is to give a systemic, holistic understanding of the basics of probabilistic reliability and risk methodology concepts of diagnostics, integrity, safety, and security of transmission pipelines. It will give the attendees a deep and thorough understanding and knowledge of risk, integrity, safety, and how to use this knowledge in practice for optimization of operation and maintenance of transmission pipelines.
Who should attend
Gas and liquid operators, maintenance, repair and inspection personnel, governmental regulators, decision-makers, human-resource managers, risk managers, specialists in new and emerging technologies for pipeline integrity and safety, among other pipeline professionals. Participants in the course will leave with a working understanding of pipeline operational excellence and a sense of the state-of-the-art. They will be equipped to help lead their own firms in an intelligent manner.
Lecturer
Prof. Sviatoslav Timashev, Ph.D., has more than 25 years’ experience in pipeline reliability (including human factors), remnant life, diagnostics, maintenance, integrity, quantitative risk analysis, safety and security. Much of his work has been for (among other clients) the Russian oil and gas majors Gazprom and Transneft. Prof. Timashev has authored and co-authored 21 books and more than 300 technical papers on the reliability, integrity, diagnostics, maintenance, remnant life, safety and security of large distributed systems such as pipelines. An internationally recognized expert, he has lectured worldwide, including the USA, Russia, Italy, China, Australia, South Africa, Austria, and The Netherlands. Professional memberships include Charter membership in the International Association on Structural Safety and Reliability (IASSAR); the ASME Pipeline Systems Division Technical Committees on Operation & Maintenance and Risk & Reliability; the API 1163 ILI Qualification Standard Work Group; and the Interstate (CIS) Science & Engineering Council on High-Reliability Transmission Pipelines. Prof. Timashev also serves on the editorial boards of several industry and professional journals, including Structural Safety, Condition Monitoring & Diagnostics Engineering Management (COMADEM), Control & Diagnostics, and the Journal of Pipeline Integrity. He is currently director of the Science and Engineering Centre at the Ural Branch of the Russian Academy of Sciences at Ekaterinburg.
Continuing Education Units (CEUs)
On satisfactorily completing the course, participants will be eligible to receive 2.6 CEUs.
Course Documentation
Participants receive a sturdy ring binder containing all the lecture slides with notes and illustrations supporting the lectures and providing an invaluable reference source after the course.
