HAZOP Tab

This Node grid can be used to record the HAZOP. Here you can define the HAZOP Nodes , and then identify potential Deviations , feasible Causes , likely Consequences (& their Severity ), and the Existing safeguards. You can also add R...

Above, and on the right of the HAZOP grid, are Toolbars (see image below). The table explains the functions. The HAZOP Tab toolbars. The HAZOP Toolbar:  Note : Not all icons are available for all columns, e.g., a Node  and De...

The HAZOP grid is organized as cards (cells). Several keyboard shortcuts have been enabled to accelerate the navigation and the editing of the cells, like in an Excel worksheet. These are summarized in the table below . The actions depend on the mo...

The objective of a HAZOP is to review the design, with an intent to identify design and engineering issues that may otherwise not have been found. The technique is based on breaking the overall complex design of the process into several simpler sect...

For each Node , the HAZOP team can use a list of standardized guidewords and process parameters to identify potential Deviations  from the design intent. Defining Deviations For each Node, define its Deviation(s): Click on the Deviation ...

For each Deviation , the HAZOP team should identify feasible Causes and likely Consequences . Defining Causes For each Deviation , define its Cause(s) : Click on the Cause card next to the Deviation . Enter a Description for the Cause....

For each Deviation , the HAZOP team should identify feasible Causes and likely Consequences . Defining Consequences For each Cause , define its Consequence(s) : Click on the Consequence card next to the Cause . Enter a descripti...

When the HAZOP team identified the feasible Causes and likely Consequences it is time to add the Existing Safeguards . The team then needs to decide (with confirmation by subsequent Risk Analyses) whether the Existing safeguards are sufficien...

For each Consequence in the HAZOP, you can enter an ALARP description: Click on the ALARP card next to the Consequence (and Exiting safeguards). Enter a description for the ALARP: Click on the card and start typing; or Click the Edit butt...

For each Consequence in the HAZOP, you can enter Recommendations : Defining Recommendations For each Consequence , define its Recommendations : Click on the Recommendation  card next to the Consequence (and ALARP). Enter a descriptio...

When a LOPA has been created and linked to a Consequence in a HAZOP , then the following will be synced: The Consequence and highest Risk (Severity*Likelihood) among the associated Consequence categories. The associated Cause(s)  (H...

When the team has finished documenting the Hazard & Operability (HAZOP) Study it needs to be Approved. A consistency check will confirm that all mandatory information is in place before approval is enabled. To edit an Approved HAZOP you will n...
