Risk-Based Inspection Technology

[hermes]

Thank you very much f81aa.

Hey, I have that API RP-581 2nd Ed. release September 2008

I can share but please do me a favor:
1. is there any discussion forum about this standard? cause I want to built software about it (I have already built Excel spreadsheet of this code with several limitation)
2. can you share me SLAB or DEGADIS calculation logic (not only software) ? cause in RP-581, Consequences Level 2 needs Cloud Dispersion Analysis
3. can you also share me any Fluid Property Solver calculation logic (not only software), this is also needs for Consequences Level 2 calculation

Please let me know. Thanx

Hi Christian Sembiring:

Let me answer your questions the best I can.

As far as I know, there are no Forums in EGPET at this moment where API 581 is being discussed. However, as a member, you can start a thread or blog with your questions and see how it goes.

I do not have neither a sofware for calculating fluid properties nor solver calculation logic. When I need fluid properties, I look them up in a handbook. I know your needs are different. If it helps, the book The Properties of Gases and Liquids by Bruce E. Poling, John M. Prausnitz and John P. O’Connell might help you in estimating properties. I saw the title of the book been posted very recently. Just have to search in the forums.

Finally, I've got the feeling that you are very enthusiastic in developing your software. I like that because it means that a new tool would be available.

I tell you what I would do in your case:

I believe that to be successful in developing a software that stands out among others, the developer has to understand the theory behind the models. And you are asking for information so that is a good start.

There are many books on the subject, I will give you some titles, knowing that I have missed some important ones. Other members will surely add others.

Handbook of Chemical Hazard Analysis Procedures by U.S. FEMA, U.S. DOT and U.S. EPA. It can be downloaded from EPA website.
Gas Explosion Handbook by Dag Bjerketvedt, Jan Roar Bakke and Kees van Wingerden. It can be downloaded from

[link Point to another website Only the registered members can access] Chemical Process Safety: Fundamentals with Applications (2nd edition) by Daniel A. Crowl and Joseph F. Louvar

The Center for Chemical Process Safety (C.C.P.S.) of the American Institute of Chemical Engineers is a leader in providing technical information on this subject. Some books worth reading are:

Guidelines for Consequence Analysis of Chemical Releases by Center for Chemical Process Safety (C.C.P.S.) of the American Institute of Chemical Engineers
Chemical Process Quantitative Risk Analysis
Concentration Fluctuations and Averaging Time in Vapor Clouds
Estimating the Flammable Mass of a Vapor Cloud
Evaluating the Characteristics of Vapor Cloud Explosions, Flash Fires, and BLEVEs
Understanding Atmospheric Dispersion of Accidental Releases
Understanding Explosions
Wind Flow and Vapor Cloud Dispersion at Industrial and Urban Sites
Use of Vapor Cloud Dispersion Models

These books cover different phenomena, provide the logic and steps for carrying out the calculations (SLAB, DEGADIS and more) and give you the backgroun to understand the limitations.

If it helps, I really like Chemical Process Safety: Fundamentals with Applications.

The C.C.P.S. books can be obtained from

Finally, forgive me if I am not able to quickly answer your questions. The quality of my internet connection is a joke and I have to wait until weekend arrives to have access through a better ISP.

I hope I was able to help you.

thank you very much f81aa, big regards to you

Yes, I do really enthusiast with this project, because since my Final Project in my Bachelor Degree, I have been learning about Risk Based Inspection with this standard
Thank you very much, I will search your recommended book first, especially about Vapor Cloud Dispersion Analysis first
and about making new thread, that is really good idea
thank you and I do really appreciate it
It has been about 2 years I have learning to understand this standard and I am still do not want to give up !!
