2. FRAMEWORK OF HAZOP STUDY

2.1. Objectives

The purpose of the HAZOP Study / Assessment is as follows:

1. Identify all probable hazards, wh
which
ich are inherently exist in the p
process
rocess in terms of physical
physical / chemical
characteristics of material and operating condition and /or operability problems;
2. Judge whether a an
n identified hazard ne
needs
eds to be mitigated by:
by:
a. Engineering control (design modification), or by
b. Administrative control (operation / maintenance
maintenance procedure)
3. Identify hazards, for wh
which
ich future follow-up studies a
are
re required.

It should be underlined that the HAZOP study is not a design review therefore the team should be
reminded to avoid spending too much time for “Design Solutions”. The following items shall be subject
to the HAZOP study:
1. Process line
Major process lines and related utility lines contained in the subject P&IDs.
2. Chemicals
 All Hazardous material such as flammable,
flammable, explosive and toxic.
3. Equipment
 All process equipment identified on the subject
subject P&IDs.
4. Instrument Controls
 All basic process control system shall be considered for the effect during hazard identification. In
addition to this, main interlock system may be considered on the subjected P&IDs basis.
5. Operating Conditions

HAZOP study shall investigate the potential hazard and problem which are likely to occur during typical
normal operating conditions. Consideration should also be taken for start-up, normal shutdown and
emergency shutdown as a deviation from the reference (normal condition).
2.2.. Scope of Study
2.2

The scope of study covers all P&IDs latest achieved NO OBJECTION status revision that has been
developed by the Contractor as part of the Design Drawing. Those include all facilities in the Gresik
Gas Cogeneration Plant (GGCP) Project. System or unit are classified as in Table 3 below, shall be
subjected to the HAZOP Study.

2.5. Methodology

2.5.1. Overview
HAZOP Study to be conducted primarily using the HAZOP deviation guideword technique. The
guidewords, in conjunction with the key process/ control parameters, prompt the HAZOP team to
brainstorm possible causes and potential consequences of deviation from design intention. For
example, the deviation “more pressure” would prompt the leader to ask the team “what could cause
more pressure in this section or line segment?” the ‘”possible cause” and potential consequences
scenarios are documented in the report worksheets. The “Existing system and procedure”
(safeguards) that reduce the risk associated with the specific cause/consequences
cause/consequences scenario are then
discussed and documented. For scenarios involving significant risk, “Recommendations” that the
team believes further reduce risk or improve the operability/controllability of the facility are also
documented.

2.5.2.. HAZOP Stud y Proced ur e

2.5.2

The guide word HAZOP method shall be applied for the review. The work flow of the review and the
list of applicable HAZOP guide word/process deviations are shown in Appendix I, respectively. The
specific steps of the HAZOP methodology used in this study are:
a) Choose study section or node
b) Apply a deviation (guideword+ parameter)
c) Brainstorm cause of deviation
d) Develop each ca cause
use to its global consequences
e) Identify existing safeguards
f) If warranted, ma make
ke recommenda
recommendation tion (s) to red
reduce
uce risk and / or improve the operability of the
facility

This process is repeated for each deviation and section/NODE until the entire process and control
system has been analyzed according to study flow diagram at Appendix II.

2.5.4. Study Worksheets

Study worksheets were used during conducting HAZOP review shall consist of, but not limited to:
a) Node,

b) Design Condition/Parameter,
c) Deviation,
d) Cause,
e) Consequence,
f) Safeguard,
g) Recommendation,
h) Responsibility.

3 Team Member to evaluate effects/hazard caused by deviations, elaborate causes of deviations,

elaborate the evaluations of safeguards and criticality.

Review result shall be recorded by HAZOP secretary using spreadsheet 

spreadsheet  based HAZOP worksheet
displayed on projector screen to enable team members confirming and correcting recorded review.

The systematic approach of a HAZOP requires deviations (guide works+ parameters) be uniformly
applied to all sections under study. The work flow of HAZOP review in Appendix II shall be used for
each study section/node as much as applicable.
2.5.5. Recommendations

Team emphasized that some of existing safeguards were considered not sufficient; therefore team
could request additional safeguard or further study. HAZOP Secretary under direction of chairman
shall document the recommendation into HAZOP worksheets

Recommendations should be carefully

carefully worded to avoid ambiguity or or confusion. Particular effort
should be made to ensure recommendations are clear enough to be understood by project team
members who did not attend or may not have a clear recollection of the HAZOP workshop, or when
read out of context i.e. read separately to the hazard, initiating event, consequences and controls.

Finally, all recommendations should include a person or entity that will be responsible for
recommendation. 
implementing the recommendation. 

2.6. Report Content

The information gained from the HAZOP shall be translated into a report incorporating, but not limited
to:
  Executive Summary.
  Introduction, Purpose and Scope of Work.
  Brief description of the facilities.
  HAZOP Methodology in compliance with the procedure.
