• Fire and Gas System Engineering - Performance Based Methods for Process Facilities (EC56P)


    Course #:  EC56P
    Length:  3 days (21 hours)
    CEUs:  2.1
    Times:  8:00 a.m. - 4:00 p.m.


    "Helped me to validate the design of future facility installations. The course gives the reasons and methods to properly design a first & gas system. The software exercise is incredible, as well as the instruction." ~ Larry French, EC56P Student

    Fire and gas detection and suppression system design techniques that are currently in use are often considered to be unsatisfactory due to their nature of being rule of thumb and experience-oriented without any real ability to quantify risk.  This has resulted in systems that are either overdesigned or under-designed. Only after the ISA TR 84.00.07, was a comprehensive framework for performance-based fire and gas design established.

    This course describes the techniques recommended in the technical report, along with hands-on use of the techniques and associated software tools.  This course was designed for all audiences from high-level decision makers and users of FGS including a basic understanding of design techniques to a comprehensive case study that involves employing software to develop a complete performance-based design for a sample oil and gas production facility.  

    You Will Be Able to:

    • Understand the scope of fire and gas engineering for process facilities and the myriad standards, regulations, and requirements
    • Review the fire and gas system design methods and guidelines that are currently available including their strengths and limitations
    • Explain the Safety Lifecycle (per IEC 61511 / ISA 84 and ISA TR84.00.07) and how they can provide a framework for functional safety of Fire and Gas Systems
    • Identify and define the fire and gas zones along with the hazards contained in those zones.
    • Discuss quantitative consequences analysis and how it is employed in performance-based fire and bas system engineering
    • Analyze the impact on overall risk of the consequence scenario and the beneficial effect of fire and gas systems using consequence integration and event tree analysis
    • Apply statistical analysis, industry databases and data integration techniques to assess the likelihood of fire and gas system relevant events
    • Assess the tolerability of the risk posed by a process facility before and after application of fire and gas detection and suppression systems using risk integration techniques
    • Define the strengths and limitations of the technology options for fire and gas detection sensors
    • Apply fire detection coverage mapping and gas detection coverage using a system performance assessment tool
    • Determine the impact of the probability of failure on demand of fire and gas system equipment on the overall risk profile of a process facility
    • Determine the impact of mitigating the magnitude of consequences of fire and gas release events on the overall process plant risk and the difference between prevention and mitigation
