HAZOP (Hazard and Operability Analysis) is a
hazards identification tool which can be analyzed using
SheelHAZOP software. SheelHAZOP is a comprehensive Personal
Computer program for the management of Hazard and Operability
Studies (Hazops)
SheelHAZOP software was designed as an aid to the HAZOP team by
providing an easy method of customizing, recording, managing and
reporting the study. The main features of SheelHAZOP can be
described under the following headings:
1. Setup/Customisation:
The user can input general information about the Hazop study, the
system under investigation and the study participants. The user
can add to the standard lists of guidewords and parameters to
customise the study for a particular type of system. The forms
through which the study information is entered can also be
customised. When the Hazop study information has been transferred
to the SheelHAZOP database it can then be filtered, sorted and
reported in a user defined form.
2. Study Editor: The details
of the Hazop study are entered into the SheelHAZOP forms that were
designed in the setup/customisation phase. In cases where problems
are identified which cannot be resolved during the study session
then actions are allocated to individuals or groups which are
documented in another SheelHAZOP form. The HAZOP study may include
risk ranking in which the likelihood and consequence of an event
can be defined.
3. Action Editor: The actions
which are assigned during Hazop study sessions are documented in
the Action Editor. In addition to entering this information into
the database, the Action Editor provides features to examine
actions based on various selection criteria.
4. Reports: At any time in the
Hazop study SheelHAZOP can be used to selectively display the
study information and prepare customised reports for printing.
This powerful feature gives the user great flexibility to examine
and report on the important information generated during a study.
Objective of SheelHAZOP
The management of the Hazop information is the objective of
SheelHAZOP. The software allows the user to customise the
interface through which the details of the study are entered. The
user can choose to have data entry fields under standard headings
such as item, parameter, guidewords or consequence. A set of such
information will be called a study record. SheelHAZOP provides the
capability for the user to specify that a particular deviation
cannot be resolved immediately and that an action record is to be
created. It is possible to categorise selected headings in the
study and to link these parameters to a risk ranking index that
indicates the seriousness of the occurrence.
Analysis
HAZOP studies performed in SheelHAZOP can be analysed with respect
to:
• Risk Ranking
• Proposed Actions
Benefits of SheelHAZOP
• It helps you to customise your Hazop study.
• It provides a very convenient way to enter and store the study
information. The
information stored can be filtered sorted and displayed.
• It also offers a powerful report generator for the printing of
quality reports.
• Risk Ranking and Proposed Actions Analysis is also possible.
