Understanding overpressure protection, depressuring and flare systems

A PSE Oil & Gas training course

Duration: 3 days

Cost: Contact PSE

Evolving industry guidelines are changing the way Oil & Gas companies approach process safety in pressure relief, blowdown and flare systems. Engineers and operators should keep up-to-date with best practices and current requirements.

PSE’s Centre of Expertise in pressure relief, flare and blowdown offers training courses to improve understanding in this important area. These training courses are complemented by free webinars and public seminars offered as part of PSE’s worldwide Oil & Gas seminar series.

This 3-day course provides detailed, comprehensive training. Participants gain a practical understanding of the design requirements, technology and systems required through examples and group exercises.

    • Day 1: Introduction to pressure relief devices, causes of overpressure, industry codes of practice and standards
    • Day 2: Sizing and selection of relief devices, depressurisation systems for fire protection and loss of containment, impact on flare systems and materials of construction
    • Day 3: Flare systems and their applications, layout and plot considerations, environmental considerations and smokeless flaring, gas seals, purging and flare gas recovery

Each day concludes with a short test to check participants’ understanding. Participants will receive a certificate of training. The course fee includes lunch and refreshments each day. The course fee does NOT include overnight accommodation, parking or meals outside of course hours.
