This two-day course will provide participants with a high level understanding of the Canadian Standards Association CSA Z662 Oil and Gas Pipeline Systems Standard, with an emphasis on practical application of the standard to oil and natural gas pipelines and facilities over the complete lifecycle from design, construction and operation in onshore areas.  The course will discuss how the CSA Z662 standard and pipeline regulations act together and it will also highlight differences in key areas between CSA Z662 and ASME B31.3.  The course is designed for pipeline engineers, technologists, inspectors or other professionals who require a working knowledge of the standard. Participants are encouraged but not required to bring a copy of the Standard (not included in course fees) to the sessions.

Duration and Training Method

Two classroom days providing 1.6 CEU (Continuing Education Credits) or 16 PDH (Professional Development Hours)

 Participants will learn to:
  1. Understand how CSA Z662 is developed and how the standard and pipeline regulations interact to contribute to pipeline system safety;
  2. Learn the practical application of CSA Z662 to the pipeline system lifecycle from design, construction, operation, maintenance and abandonment;
  3. Become aware of Safety and Loss Management System, Integrity Management Program and Engineering Assessment concepts;
  4. Obtain foundational knowledge of CSA Z662 pipeline design and material requirements;
  5. Understand when ASME B31.3 may be used within a CSA Z662 design and the key differences;
  6. Learn the main requirements for construction, welding, pressure testing and corrosion control and their practical applications;
  7. Recognize operations and maintenance requirements and relevant issues such as safety considerations and procedures and records requirements;
  8. Learn the requirements for imperfection evaluations, acceptable repair methodologies, deactivation, reactivation and abandonment; and
  9. Obtain a working knowledge of the application of the standard through the use of examples and contextual discussion of the intent of the clause.

Alternative Dates for this Course

This course is great for looking at the bigger picture and intent of CSA Z662. This high level understanding would be advantageous for all involved in Oil & Gas including all levels of management (projects, operations, documentation, Health and Safety, etc.) as well as all levels of technical groups (Engineers and Project Eng., technicians, drafting, trades, etc.). Awareness and understanding the intent of the code is important for all facets of business related to Oil and Gas.
