Get more out of your data, quantify your bowties

Take your risk assessment to the next level with BowTieXP and LOPA

BowTieXP and LOPA feature overview

Quantitative & qualitative data

Bowtie diagrams give a better understanding of your risk scenarios and show how these are controlled. In classic bowtie modeling, the decision as to whether there are sufficient effective barriers to control these scenarios, is based on expert judgment.

When your organization has reliable and sufficient safety data available, the LOPA plugin will allow you to use this data to make more objective and substantiated decisions.

Bowtie-based LOPA

Layers of Protection Analysis (LOPA) is a semi-quantitative risk analysis methodology. Hereby the frequency of a negative event is calculated according to the risk reduction delivered by the independent protection layers (barriers).

The BowTieXP LOPA plug-in automatically calculates the frequency of a consequence, given the initial frequency of all the threats and the Probability of Failure on Demand (PFD) of the barriers. This allows you to easily compare the target consequence frequency with the reality of daily operations.

Create insightful reports

Analyze and share your LOPA calculations by creating useful reports. Some reports will be based on a single scenario (traditional) LOPA calculation, while others will take all bowtie scenarios into account.

Take the next step

Make your risk calculations visible with the LOPA plug-in and put them in an easy to understand, barrier based perspective. This plug-in can be added to both BowTieXP Standard and Advanced.
