INTRODUCTION

H-Analyst™ is another sophisticated tool

developed by SaSI Innovation. It is aimed at aiding

the hazard identification study, i.e. HAZOP and

HAZID, early in the detailed engineering phase.

One of the major problems arising during the design of the Safety Instrumented Function (SIF) is

that data transferred from a HAZOP study provide insufficient details for the SIL assessment

workshop.

Moreover, some data are inconsistent when conducting the HAZOP and the SIL workshops. This

generally extends the time required for the SIL assessment for related activities, i.e. hazard

identification, demand scenario development and consequence analysis.

H-Analyst™ can eliminate the above mentioned problems because it shares the same

quantitative data with InnoSIF™ (SIL Study Tool). This ensures the consistency between HAZOP

and SIL Study. In addition, the study results from H-Analyst™ can easily be transferred to

InnoSIF™. Thus, every efforts are counted!!!

Best Practices Integrated

H-Analyst™ provides the different guide words which are specific for HAZOP and HAZID, yet the

worksheet format and the working environment for both studies are identical. Moreover, the

results of HAZOP can be directly exported to SIL Study with just few easy steps.

SMART RISK MATRIX

The Smart Risk Matrix built in H-Analyst™ version, supports both qualitative and quantitative

analysis methods and configurable up to 8X8 matrix. Example above is qualitative analysis matrix

for support HAZID study.


Quantitative analysis matrix which is consistent with InnoSIFTM (Simplified SIL Classification).

H-Analyst™ generates the predefined risk classification of 7 levels. The user can customise the

risk level to be in line with Company’s Risk Tolerability policy by activating or deactivating any

items of risk level provided.

User Friendly

H-Analyst™ interface is easy-to-use, it makes user focus on the deviation and hazard being

analysed. The tools provided are developed from the intention of working better, faster and more

effective for the overall HAZOP / HAZID processes.


LAYER OF PROTECTION ANALYSIS (LOPA)

When qualitative analysis cannot provide enough resolution for risk reduction measures

development. LOPA technique will take the risk ranking into account as (semi-) quantitative

analysis method. Required RRF (residual risk) will be reported and carried to further safety study

e.g. SIL study.

PRODUCTION LOSS EQUATION (PLE)

Production loss equation (PLE) is a good practice to make high resolution of the economic impact

assumption on the hazardous event, The PLE can be built one or more cases depending on the

production loss scenario specific on the evaluated plant.


REPORTING CAPABILITY

H-Analyst™ has a built-in report generating tool. The report is automatically developed in the MS

Excel file format so it’s customisable. Information generated in the report includes the study team

members, a list of reference and related documents, the risk criteria, assumptions, the major

accident hazard list, Safety Critical Elements (SCEs), the study worksheet and action/response

sheets.
