ProSET® Overview

ProSET® – Process Safety Evaluation Toolset combines a family of modules allowing the user to complete risk assessment activities part of the Functional Safety Lifecycle, as required by international standards such as IEC 61508 and IEC 61511.

ProSET® is a family of three tools including:

SIL Comp® – The Complete SIL Compliance Software Suite for SIL Determination, SIL Verification, Safety Requirement Specification (SRS) and Cost Benefit Analysis (CBA)

PHA Comp – The Process Hazard Analysis Compliance Tool for use in PHA studies such as Hazard and Operability studies (HAZOP studies)

DATA Comp – Operation & Maintenance Data Collection Toolset to evaluate achieved demand rates, failure rates and back calculations of SIL Verification results

A list of features of each of the modules are presented below:

Project Settings

  • Workshop sessions manager (including attendees)
  • Drawing numbers manager
  • Site structures manager
  • Assumptions manager
  • Project Information

SIL Comp®

SIL Determination

  • Risk Profile Manager
  • SIL Determination via
    • LOPA
    • Risk Graphs
    • Risk Matrix
    • Combination of Risk Graph and LOPA
    • Combination of Risk Matrix and LOPA
  • Mode of Operation selection:
    • Low Demand
    • Continuous Demand
  • Selection of consequences for specific hazards
  • Configuration of custom Initiating Events, Independent Protection Layers (IPLs) and Conditional Modifiers.
  • Results summary
  • Target Selection via:
    • Assessed Consequence Category
    • Custom SIL Target
    • Custom PFD Target
  • SIL Status settings of:
    • Open
    • Closed
    • Hold
    • Development
    • Mothballed
    • Out Of Service
    • Custom
  • Cost Benefit Analysis, CBA, via As Low As Reasonably Practicable (ALARP)
  • SIL Determination report generation
  • SIL Assessment (Determination and Verification combined) report generation

SIL Verification

  • Works in tandem with SIL Determination using SIL Target, PFD/PFH Target and SIL Status
  • Allows voting of independent channels from 1oo2 to 3oo4.
  • Use of Subsystems allowing complex SIFs to be modelled e.g. 1oo2 Subsystem configuration of which each subsystem could contain voting
  • Modelling of Non-redundant voting allowing for all elements to be included within a single calculation for duty / standby arrangements e.g. single valve in operation in a SIF but could be lined up to stream A or stream B therefore 1oo1 voting but could be either element
  • Allows for the configuration of Custom Failure Rate data attained from manufacturers or other sources
  • Allows custom MooN voting for non-independent channels, with maximum N value of 15
  • Live view Reliability Block Diagram (RBD) when configuring a Branch
  • Complete RBD view of SIF
  • Architectural Assessment using either IEC 61508:2010 Route 1H or IEC 61511:2016 method
  • Estimation of achieved response time and evaluation of whether the process safety time has Sensitivity Analysis for optimisation of the SIF
  • SIL Verification report generation
  • SIL Assessment (Determination and Verification combined) report generation

Safety Requirement Specification

  • Works in tandem with SIL Determination, extracting the Sources of Demand, Demand Rate on SIF and the SIL Target and PFD Target
  • Allows for input of information to pre-configured fields as per the requirements set in IEC 61511
  • SRS report generation

PHA Comp

  • Management of Nodes
  • Default and Custom Deviations (Parameter and Guideword combinations)
  • Actions Manager
  • Assignees Manager
  • Risk Ranking of Cause / Consequences
  • PHA report generation
  • PHA Actions report generation

DATA Comp

  • Configuration of Elements installation data (date installed, Serial Number, Service, decommissioning data etc)
  • Record demands and failures per element
  • Evaluates failure data by group (based on the Device, Failure Mode used and Duty Type)
  • Recalculates your PFD/PFH Achieved (from SIL Verification) based on your actual failure rates
  • Recalculates your Demand Rate (from SIL Determination) based on your actual Demands
  • Results are shown as to whether your Demands, Failure Rates and recalculated PFD/PFH Achieved values are better or worse than predicted
  • DATA Comp report generation
