FLACS-Risk Development
►50%-75% of work in initial FLACS-Risk development is building the framework to efficiently move from running a hand full (1-20) to many (100s-1000s) simulations

FLACS-Risk Initial v1.0 ReleaseOur goal: Allow users to easily and efficiently perform risk-based safety studies using FLACS.
Functionality Primarily focus on input to design (e.g. Design Accidental Load)
Limitations v1.0 release: Ventilation, dispersion and fire modelling Steady state and transient modelling UKOOA ignition model Single module/area

Early Adopter Programme►You can get: Early access to the world’s #1 decision making tool for asset design
Access to a consultant who is dedicated to support your project
Training, support and competence building: Advisory/Jumpstart services are central to the delivery
A free (time limited) FLACS-Risk license
►We get: Key references to use in promoting FLACS-Risk
Valuable feedback on our product
FLACS-Risk: Product presentation FLUG May 2016
Early Adopter Programme: How
►We need five early adopters globally
Customers that do not yet have much experience with FLACS-Risk studies
Minimum three risk-owners: National and international oil and gas companies
Target personnel: Site HSE Managers, Project responsible
FLACS-Risk: Product presentation FLUG May 2016
Early Adopter Programme: What
►Project Requirements
Small to medium sized facility: both with respect to number of leak locations and calculation domain
Flammable/toxic gas dispersion and/or jet-fire risk studies
Specific issue where 3D risk results may provide additional value:
• Some 3D aspect in project: Offshore platform, terrain, buildings or walls near releases
• Focus on input to design, but may also investigate risk to site personnel on small enough sites
No fast-track projects: Delivery dates needs to be flexible +/- two months
Low-hanging fruit: re-do an old project

Summary and Conclusion
FLACS-Risk is a new, unique software solution for 3D CFD risk modelling and visualisation.
►3D visualisation of risk to:
Efficiently communicate and improve risk-owners understanding of safety issues
Reduces the cost of design, engineering and construction
►More efficient workflows reduces man hours and lead-time of running simulations by more than 25 %
