Simulation of Search and Rescue Operations on Seas with Collective Behavior

In spite of the fact that shipping is very safe, disasters are still taking place when a ship’s crew and/or passengers have to abandon the vessel. Search and rescue operations are complex and have to take into account currents, weather, and sea surface conditions.

We simulate human body motion induced by wind and waves. To simulate sea waves we use FFT. Hydrodynamic and hydrostatic forces are integrated directly using the random sampling points on the submerged vessel surface. The collective behavior takes mutual agent visibility, occluded by fog and wave shape, into account.

This video illustrates the evolution of the network of visual contacts of shipwreck victims. The network evolves under the influence of wind and waves. This network analysis facilitates the development of a search and rescue operation strategy.
