FLACS Frequency Software
A Gexcon X Suite Product

A Web-Based Tool for Release Frequency Assessment

Providing quality assured analysis into the frequency and location of flammable and toxic fluid leaks at processing facilities.

Launched in September 2020, FLACS-Frequency is based on models derived from major research projects, delivering unrivalled integrity and accuracy for safety specialists.

An easy to use web-based tool, it gives quick sensitivities and includes 3D modelling to visually highlight risk areas.


Key Benefits

User-friendly and intuitive

No prior knowledge of release frequency calculation is necessary. Simply enter your process system and equipment data, choose a release frequency model and the results are immediately available.

Quality assured

Based on innovative new technology with industry standard release frequency models, it also allows for user-defined models to be incorporated.

Based on highly respected research

Draws on major projects including the UK Health and Safety Executive Hydrocarbon Release Database and the Trends in Risk Level Norwegian Petroleum Activity databases.

Quick sensitivities

Quickly set up and run sensitivity cases for changes to equipment such as flanges, valves, instruments, storage tanks.

3D Modelling

Displays release frequency results in 3D geometry modelling to visualise high-risk areas.

Communicates results effectively

Organise work into projects and cases so teams can seamlessly collaborate on entering data, setting up analyses and sharing results.

Central software management and data storage

The software is provided via a cloud-based solution. Alternatively, the software can be installed on a local server so that all data remains on internal systems
