Hydrostatic Testing of Pipelines
December 5-6

Course schedule
Day 1-2:  8am-5pm

This course is designed for pipeline personnel in engineering, integrity management, operations, and regulatory compliance roles. This course will cover a wide range of topics related to hydrostatic testing of pipelines for gas and hazardous liquid service for both in-service and new construction according to CFR 49 Parts 192 and 195.

Course Objectives

To provide attendees with necessary information for planning and conducting a successful hydrostatic test, whether it’s for initial service or retesting existing lines. Planning will cover review of integrity prior to testing through evaluation of test results. The course will focus on testing with water but testing with other medium will be discussed.

Lecturer

Gary Zunkel, PE, is the Director of Mainline Engineering with Lake Superior Consulting in Duluth, MN.  He has been involved in the oil and gas industry for over 30 years with the last 10 years focusing on pipeline integrity management.  He has been involved with over 100 pipeline tests; planning, managing, and reviewing.  In recent years, he has planned and conducted multiple, simultaneous tests on large diameter in-service pipelines for integrity verification.

Who Should Attend

The course is intended to cover the technical aspects of planning and conducting a hydrotest.  It is designed for engineers, project managers, integrity management, and operations personnel to prepare for testing.  The following topics will be covered:

  • Pipeline integrity review
  • Water source identification, disposal, and permitting
  • Leak detection
  • Risk assessment and contingency planning
  • Calculations for test pressures according to 49 CFR 195
  • Assessment of test results, including methods of analyzing pressure discrepancies
  • Test scheduling
  • Documentation for regulatory review

Continuing Education Units

Upon completion of the course, participants will be eligible to receive1.4 CEUs.
