Webinar Topic List

Back to Basics: What You Need to Know About Dispersion Modelling 

21st October 2020, 2:00 PM to 3:00 PM IST (GMT+5.30 hrs)

Speaker:

Dr. Prankul Middha 

Principal Consultant, Director 

CFD Modelling Expert,

Abercus, UK 

Adjunct Professor IIT-Delhi


Synopsis:


The webinar will discuss various parameters that influence the dispersion of the flammable/toxic gases following a release. This includes density, temperature, ventilation conditions, process stream, etc. Various modelling techniques will be discussed, including both simplified methods involving the use of integral models as well as more advanced techniques such as those based on Computational Fluid Dynamics (CFD). Discharge modelling will also be included in the seminar as that is important to determine accurate source terms for the subsequent dispersion modelling. We will discuss why CFD techniques are the most appropriate for such applications, especially in the complex process facilities. The measures of gas cloud sizes used for risk analyses will also be covered.

Human Factors in Barrier Thinking and Bowtie Analysis 

4th November 2020, 2:00 PM to 3:00 PM IST (GMT+5.30 hrs)

Speaker:

Prof. Ron McLeod 

Independent Human Factors Consultant,

Ron McLeod Ltd,

Glasgow,UK


Synopsis:


The webinar will contrast two recently completed Bowtie studies:  one facilitated for an oil and gas service company through a face-to-face workshop immediately before lockdown restrictions came into force in Europe; the other carried out in the rail industry using virtual meeting arrangements during lockdown  While it required a different way of working, the depth and quality of the virtual analysis turned out to be significantly better than the analysis facilitated face-to-face.
