    This report describes the feasibility demonstration of a new method to perform risk assessments for offshore platforms. This method simulates the following phenomena as concurrent sequences of events using the Arena® Discrete Event Simulation (DES) software (version 14.50.00):
    • Release, ignition and fire;
    • Detection, shut down and alarm;
    • Escape and evacuation;
    • Exposure and impact on people and equipment
    This method leads to a transparent framework for modelling, which helps to demonstrate the correctness and appropriateness of models and assumptions.
    The report lists the (type of) models and data needed for the risk assessment framework, and provides specific suggestions for some of those models.
    Some preliminary calculations with the DES model have been performed to illustrate type of results that can be obtained and to provide some insight in the accuracy and computational efforts.
    Finally, further work is identified in order to develop an operational risk assessment tool.
