BOW TIE IN RISK MANAGEMENT
Bow Tie Approach
Bow Tie approach is a qualitative risk analysis tool that helps the operational and maintenance teams to focus on barriers (i.e., preventive and mitigative safeguards) to maintain operational safety. It visually demonstrates an effective management of all barriers which is a crucial aspect of risk-based process safety management.
The Bow Tie diagram consists of consequences of a certain hazard and ways in which the organization can prevent those consequences from happening. The method acquired its name from the outcome of its analysis, which is a visual diagram that looks like a men's bow tie.
From the left-most side of the Bow Tie diagram are the threats, followed by the preventive barriers. The center (or the knot) displays the top event which is the moment in time when control over the hazard (above the knot) is lost, making the consequence imminent. Finally, from the center of the diagram to the right are the mitigative barriers and then the consequences. Degradation factors acting on barriers and its controls can also be incorporated.
A Bow Tie Diagram in 6 Steps
There are 6 basic steps in building a Bow Tie Diagram
Process Safety Improvement with Bow Tie
Saltegra facilitates Bow Tie sessions across different industries (e.g pharmaceutical, oil and gas, chemical manufacturing), making it possible to remarkably improve their process safety. We do this by:
Aside from Bow Tie facilitation, Saltegra also offers Bow Tie training workshops to equip the people of your organization with the knowledge of the Bow Tie approach in risk management through:
explaining the Bow Tie methodology using interactive examples and industry-specific scenarios
demonstrating how to construct Bow Tie diagrams using a respective software tool
Overall, the Bow Tie diagram can provide a clear graphical representation of how to manage the risks. This representation can be readily understood by people at all levels – from operational personnel, senior managers to regulators and members of the public. Bow Ties can also be used in the design phase to test the adequacy and relevance of barriers, and if additional barriers and degradation controls are required. Creating these risk assessment diagrams, used to make risk communication very efficient, has never been easier with CGE Risk Management Solutions’ software - BowTieXP.
BowTieXP, a software that makes it easy to create Bow Tie diagrams to assess risk, is an in-demand risk assessment software that is based on the approach of Bow Tie. This visual diagramming tool:
has the unique ability to visualize complex risks in detailed risk-based improvement plans in a way that is easily understandable
allows the maintenance of the diagram to always be updated on the current status of your safety barriers
Features of BowTieXP
BowTieServer combines all the main software solutions of CGE and unifies them across the organization. These powerful tools include BowTieXP, IncidentXP, and AuditXP. BowTieServer also offers the BowTie WebViewer feature which enables the viewing and visualization of the diagrams in a web browser.
BowTieXL gives you freedom to create what you specifically need by allowing you to do spreadsheet calculations based on your data. With this, you will be able to generate your own methods for quantified and visual risk assessment in BowTieXP.
