an integrated naval architecture design and analysis soſtware produced by Qinetiq. Its object based description of the ship design, interactivity and extensibility made it the most suitable tool for use in the demonstration. Product model specifications can be very
detailed, allowing their direct implementation in software tools etc. The aim within the FIREPROOF demonstration was not to develop such a detailed specification, but rather to identify the contents, concepts and modelling techniques that would be required of a future more detailed specification. Tis development was carried out by a process of increasing focus and detail, which also contributed to the division of labour in the

demonstration activity. Figure 7 provides a summary of the process of survey and grouping used, including the consideration of the use of the FIREPROOF methodology in the ship design process, which constrains the amount of detail available at a given point in the design development.
Demonstration Te SPM and interface tools were used as part of the modelling process to allow a campaign of simulations to be carried out. Figure 8 shows the Paramarine model, which represented two zones of a generic cruise ship. Tis model contained 2451 objects, including 1263 spaces and 1117 connectivity items. Figure 9 shows this geometry transferred to SMARTFIRE Scenario Designer, Figure 10
shows it in maritimeEXODUS and Figure 11 is an isometric view of a single deck in SMARTFIRE.
Conclusions The FIREPROOF project is developing a probabilistic, risk-based approach to fire safety for passenger ships allowing the rational assessment of risk for both conventional and novel designs. Tis project has seen the development of modelling and analysis tools addressing all aspects of fire, from ignition to spread and consequences for the passengers and crew. To support these analyses, including simulations using a new hybrid CFD / Zone model, the basis specification for a Ship Product Model (SPM) has been developed. Ultimately, the FIREPROOF framework will be submitted to IMO (FP sub-committee) for discussion and further consideration. NA
