RISQ
Risk-Integrated Solution for Quantitative assessment
Quantitative risk assessment for marine and process systems, from leak frequency to societal and individual risk in one browser-based tool.
RISQ brings the whole chemical process quantitative risk analysis (CPQRA) procedure into one tool. You model the system once, and the result of each step feeds the next: leak frequency, event tree, consequence analysis, then F-N curves and individual risk.
Built for Alternative-fuel ship systems (LNG, hydrogen, ammonia), bunkering and engine-room piping.
Workflow
Four tabs, one model
- 01
Modelling
Build the system as a component diagram of pumps, compressors, valves, flanges and pipes, set each node’s phase and operating conditions, and place sources and population on a map with the site wind rose.
- 02
Frequency analysis
Leak frequency for each hole-size band from 1–3 mm to more than 150 mm, then an event tree of ignition, release duration and surrounding conditions that gives every accident case its frequency.
- 03
Consequence analysis
Leak rate, pool spread, gas and toxic dispersion, jet and pool fires, explosion overpressure and probit fatality for every case.
- 04
Result
F-N curve against tolerability lines, hazardous-zone curve and individual risk, with time-dependent risk and uncertainty and sensitivity views, and a Word or Excel report.
Consequence modules
- Leak rate
- Pool spread
- Gas dispersion
- Toxic dispersion
- Jet fire
- Pool fire
- Explosion
- Probit fatality
Inside RISQ
The model basis on every screen
Reports built in
Word and Excel reports, and a whole project saved as one .json file.
Checked step by step
A verification workbook compares each step with hand calculations, and results have been cross-checked against HyRAM+ on the same release case.
English and Korean
The interface switches between the two languages.

Data-driven, time-dependent FMEA
D-FMEA is a data-driven FMEA tool that replaces subjective expert scoring with time-dependent RPN(t) = O(t) × S(t) × D(t) computed straight from reliability data. It automates analysis, ranking and mitigation, so work that once took months of manual workshops is done in a few hours.
- Driven by reliability data, with no subjective expert scoring
- Time-dependent RPN(t) = O(t) × S(t) × D(t)
- Months of manual workshops → done in hours
CPQRA integrated risk assessment
A browser-based platform that brings the whole quantitative risk assessment workflow onto one dashboard. Drag P&ID-style equipment onto a canvas, then run leak-frequency analysis, consequence modelling (gas dispersion, fire and explosion) and quantitative risk from end to end. QRA steps that are normally separate and manual become one interactive environment with nothing to install.
- Drag-and-drop P&ID equipment onto the canvas
- Frequency → consequence (dispersion, fire, explosion) → risk
- Individual & F-N societal risk
Browser-based Dynamic Fault Tree (D-FTA)
A browser-based Dynamic Fault Tree (D-FTA) builder for any system. Load the Excel component list, assemble a fault tree with static and dynamic gates (AND/OR/PAND/SPARE/FDEP) and compute the time-dependent top-event failure probability from each component's Weibull and maintenance reliability. Minimal cut sets and optional sensor-detection coupling are included.
- Load an Excel component list, build the tree in the browser
- Static & dynamic gates: AND / OR / PAND / SPARE / FDEP
- Time-dependent top-event probability from Weibull + maintenance reliability
