An application for evacuation simulation using computational resources may help previewing situations, flows, conflicts, and behaviors that may only happen in a real danger situation. This kind of application enables the execution of several pre-defined scenarios at any time, without the expensive and complex allocation of real people. This dissertation proposes an emergency simulation system on oil platforms in 3D with real-time results using as architecture a game engine (Unity). The solution developed was tested in of real platforms models for comparison with times obtained in emergency simulations with people. System performance will be exposed, as well as future works.
