AROS 3D – About

AROS 3D software is standalone and self-contained calculation package that allows the development of a mathematical model of risk to personnel.

It is developed in a modular type design to allow modifications to be rapidly implemented should any methodology currently in use be improved or if different input models are required.

The software uses the inherent power of a computer to undertake repetitive calculations and evaluate multiple possible combinations of hazardous scenarios whilst simultaneously presenting an easily understood engineering interface / analysis to the user. The user is given the role of developing and implementing high level engineering parameters / rule-sets which AROS 3D then implements and applies to the base input data.

The AROS 3D software is for use by Engineers and Specialists who have:

• Familiarity with current quantitative risk analysis consequence modelling techniques.
• Understanding of the limits of quantitative risk analysis.
• Knowledge of links between initiating events and ultimate consequences.
• Potential interactions between seemingly independent parameters.
• Mathematical competence in frequency, probability and consequence data sets manipulation.
• Use of historical frequency, probability and reliability data.

The model assumes that a basic level of engineering input has been used to design a site / offshore platform / installation, such as:

• Inherent Safety Principles;
• Effective engineered active and passive safety systems;
• Determination of effective consequence barriers etc.;
• Temporary Refuge design;
• Escape and evacuation system.
• Personnel distribution.
