The aim of depressuring in a fire emergency situation is to prevent possible catastrophic escalation. This is achieved by routing hydrocarbons into the flare network. The effect is not only to remove the flammable inventory from the system but also to reduce stresses in pipes and vessels.

This webinar will discuss changes in the 6th edition of API 521 on fire analysis. The presentation will introduce the analytical methodology for fire analysis and explain the limitations of the empirical approach considering equipment in a well-ventilated fire area.

Topics covered

In this webinar you will learn about:

  • A brief introduction to fire analysis
    • Why is it performed?
    • What types of fire are considered?
    • What decisions are informed by the analysis
  • Changes in the 6th edition of API 521 on fire analysis
  • Description of the analytical method and its validation
  • Case examples of integrating the analytical method within fire evaluation workflows
    • Pool and jet fires
    • Vessel rupture time and required depressurisation rates


Apostolos Giovanoglou is the Technical Director of PSE Oil & Gas. He is a Chemical Engineer with a PhD in thermodynamics and has extensive experience in advanced process depressurisation and dynamic modelling for Oil & Gas applications.
