HAZOP STUDIES

Need a HAZOP facilitator in Brisbane or across Australia? Our HAZOP study consultants facilitate structured hazard and operability workshops, including guideword-based deviation reviews, multidisciplinary action tracking and clear HAZOP study reports for design and operating facilities.

HAZOP Study Consultant & Workshop Facilitation Australia

Independent HAZOP study facilitation and process hazard analysis for Australian oil and gas, energy and industrial facilities. Structured workshops for FEED, detailed design, plant modifications and operational risk reviews, with traceable deviations, safeguards and actions.

Engineering approach

A disciplined workshop.
Useful design decisions.

HAZOP works best when the review is anchored to design intent and credible process deviations. We facilitate studies that test causes, consequences, safeguards and operability issues without turning the workshop into a paperwork exercise.

01

Preparation

Define scope, nodes, design intent, documentation and workshop readiness.

02

Systematic review

Apply guidewords to identify deviations, causes and credible consequences.

03

Safeguard assessment

Challenge protection effectiveness, independence and dependence on operator response.

04

Action quality

Record clear, proportionate actions that support practical close-out.

Workshop flow

From node definition
to action closure.

The emphasis is on technically sound preparation, efficient node-by-node review and recommendations that are clear enough to close without reinterpreting the workshop months later. A HAZOP (Hazard and Operability Study) uses guidewords such as No, More, Less, Reverse and Other Than to test credible deviations against each node’s design intent. Typical participants include operations, process engineering, instrumentation, maintenance and a dedicated facilitator. For upstream and downstream risk assessment, explore our HAZID studies, LOPA facilitation and Bowtie barrier analysis.

01Inputs and readiness

Confirm P&IDs, design intent, node boundaries, operating cases and the right workshop participants.

02Facilitation

Keep the team focused on credible deviations, causes and consequences without losing operability detail.

03Decision quality

Separate real safeguards from assumptions and identify where further protection or design change is warranted.

04Close-out

Write actions so the responsible engineer can resolve them without having to reconstruct the workshop discussion.

STRUCTURED DEVIATION REVIEW

Follow one HAZOP node from intent to action.

A practical HAZOP workflow shows how process design intent, guideword deviations, causes, consequences and safeguards lead to clear recommendations.

A HAZOP identifies and records credible scenarios; the workshop should not assume every listed safeguard is independent or sufficiently reliable.

HAZOP guidewords and workshop preparation

Our HAZOP facilitation approach considers process design intent, operating envelopes, causes, consequences, existing safeguards and actions. The workshop team should have current P&IDs, process descriptions, control and shutdown philosophies and relevant design data. Outputs typically include a structured HAZOP worksheet, action register and a documented basis for follow-up.

Where scenarios require further risk assessment, related services include HAZID workshops, LOPA and SIL target assessment, Bowtie and barrier management and functional safety engineering. Enquire about independent HAZOP facilitation.

Common guidewords include no, more, less, reverse, other than and as well as. A facilitator combines the guideword with a process parameter such as flow, pressure, temperature or level to identify credible deviations. The workshop then examines causes, consequences, safeguards and actions. See our guidewords and deviations article and node selection and preparation guide. For scenarios needing quantified risk reduction, explore LOPA facilitation.
