FLACS Frequency Software
A Gexcon X Suite Product

A Web-Based Tool for Release Frequency Assessment

Accidental release of a flammable or toxic fluid is a key risk driver at many process facilities. FLACS-Frequency provides insight into how often and where such releases are likely to occur. FLACS-Frequency combines information on your process facility with historical data on equipment failure to produce detailed leak/release frequency estimates and calculates release frequency for equipment (flanges, valves, instruments, storage tanks, etc.) at both onshore and offshore process facilities.

FLACS-Frequency is a user-friendly web-based tool that lets your team seamlessly collaborate on entering data, setting up analyses, and share results. FLACS-Frequency is ready to be deployed on your local server or cloud solution, where your data will stay on your internal systems and is not shared with Gexcon.

No prior knowledge of release frequency calculation is necessary, and the required input can be retrieved from your facility operations data.


Key Benefits of FLACS-Frequency

FLACS-Frequency makes release frequency easy. Simply enter your process system and equipment data, choose a release frequency model, and your results are immediately available. A 3D model of your process system can also be accommodated and used to visually highlight high-risk areas.

Results are visualized as tables, 2D charts, and in the 3D model. Release frequency estimates are based on the frequency model of your choice. Industry-standard models based on UK HSE HCRD (UK Health and Safety Executive Hydrocarbon Release Database) and Norway RNNP (Risikonivå i norsk petroleumsvirsomhet/Trends in Risk Level Norwegian Petroleum Activity) databases are provided in the tool, and an option for user-defined models is available.
