Advantages of advanced HAMS-GPS Software Package

Standard HAMS-GPS Software Package

Advanced Package is a single module taking you from Input Data to Final QRA-Results without any data transfer!

The standard package that has several software requiring Manual data transfer from one module to another.

Advanced Package is extremely user friendly and does not need advanced knowledge of QRA

The Standard Package requires advanced knowledge of HSE and QRA.

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 standard module requires multiple manual data entry and multiple simulations for each module separately, resulting in lot of Manual Unit conversion of Data from one Simulation in to a different Unit for another Module and so on.

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 ALAP Software available.

The Standard ALARP Module gives a fixed scale ALARP and closely falling scenarios all get overlapped making difficult to read.

The Advanced Package is specially designed for  EHS-Research and EHS-management.

The Standard Package is specially designed for EHS-Research work
