Development and Application of Positioning Support System for Maritime Accidents

A fast search and rescue positioning support system for maritime accidents is developed based on the marine basic database of flow and spilling oil mathematical modeling and tidal current mathematical modeling under wind action using VC platform, Fortran program, MapInfo and MapX control technology. The mathematical models are integrated by dynamic link libraries (DLL) created by FORTRAN language. On the basis of the database, the visual system is developed, which has a friendly interface and nice visualization, with menus, toolbars and forms similar to Windows. Research results successfully applied in surface water particle trajectory simulation of Bohai Bay and oil spill accident of a tanker. The drift path and range are in line with the simulation results to get a good effect of verification.
