The
Advanced Package enables in a single stretch of button clicks all
simulations from Chemical Storages and Properties through Scenario
Development, SMOD, Scenario Simulations for all types of
Dispersions, Fires, Explosions leading to Risk Assessment results
including FAR, FN-Relation, ISO-Risk and ALARP in one go.
|
|
|
The Advanced Package Enables scale plotting of all
Graphic outputs on Auto Cad Files using bulit in screen capture, on Graphic Files and also on
Blank sheets as per user defined scale and Wind orientation.
|
The standard package does not have this scale
plotting facility. It gives fixed scale graphs in vertical
position only, with no reference to wind direction
|
|
The Advanced Package under Risk Assessment option
includes built in computation of Risk based Investigation (RBI)
Matrix.
|
RBI-matrix is available in Standard package only as
a separate module and has to be run after manual data entry by
taking the data from other simulations only.
|
|
The
Advanced Package ALARP diagram has Scale adjustment facility so
you can see each scenario distinctly from other closely positioned
scenarios, a facility unique for any ALARP Software available.
Mapping
of hazardous zones on picture files is available in advanced
software
only.
|
The
Standard ALARP Module gives a fixed scale ALARP and closely
falling scenarios all get overlapped making difficult to read.

1.The
‘Red Book’, describing the methods for determining and
processing probabilities, is to be used to derive scenarios
leading to a loss of containment event [CPR12E].
2.The.
‘Yellow Book’ describes the models to determine the
outflow and dispersion of dangerous substances in the
environment [CPR14, CPR14E], and finally,
3.The
‘Green Book’ describes the impact on humans of exposure to
toxic substances, heat radiation and overpressure [CPR16].
|
1.
Has Provision for determining Scenarios and Probabilities of
failures leading to Containment Loss as per Math. Models
Prescribed by World Bank Guidelines and EPA Requirements. Also
allows for User Defined Failure Probabilities as given in your
Guidelines Para 3.A.2 on Failure Data.
2.
Has Provisions for Source Modeling including: Gas/Liquid for
any density Flow through pipe, through hole, Flashing Liquids,
Pool evaporations due to substrate heat transfer
(Rapid-1-min.), heat conduction and wind.
3.PROBIT
Modeling: Probability Units for computing percent and Absolute
fatality and injury for Dispersions under Stability Classes ,
Fires (Jet, Flash, Pool) and Explosions (UCVC, CVC, BLEVE,
Dust) as per your Guideline Para-4.8. and para-5

Exclusion of
particular substances
|
Excludes all

|
The
Selection Method
|
Allows only
Maximum Credible Loss Scenarios (MCLS or Maximum Credible
Accident Scenarios (MCAS) as per Scenarios
as per World Bank
Technical Paper-55.

|
Loss of
Containment Events (LOC)
|
Allows for
Selection of LOC Events based on all Conditions given in your
Guidelines for all Types of Storages and Piping systems.
