Relief System Design Training Course

Course Description:

Smith & Burgess’ Relief System Design Course provides students an in-depth overview of pressure relief system design, their requirements, and current industry-related topics. Students will also learn the guiding principals for evaluating a relief system, as well as, determining the applicability of overpressure scenarios, required relief rates, and relief device capacity. In addition, the course provides relevant updates regarding industry guidelines and standards.  (A background in engineering and process safety is helpful but not required.)


2.5 Days: Relief Systems Design Course

0.5 Day: Engineering Ethics (or topic of your choosing)


Upon completion, all participants will receive 21 hours of Professional Development Hours. 


Develop an understanding of the importance of pressure relief systems and key principles impacting their design. Become familiar with the codes and standards relevant to Process Safety Management (PSM).

Target Audience:

Engineers and others responsible for PSM, who need to perform, apply, or understand pressure relief system requirements.
