Various forecast models are available at Cedre to predict the evolution of oil or HNS spills.

In the event of an incident, it is essential to know:

  • the behaviour of the products and the associated risks
  • their movements (at the surface, in the air, in the water...)
  • what is happening and what is going to happen
  • an overview of the situation.

To do so, Cedre has tools to predict:

  • the drift of oil slicks or floating objects: OILMAP (RPS) et MOTHY (Mété-France) ;
  • the physical and chemical evolution of an oil (evaporation, emulsification, viscosity, volume) according to the environmental conditions: OILMAP (RPS) et ADIOS (NOAA) ;
  • trends and risks of hydrocarbon arrivals resulting from hundreds of probable scenarios derived from 10 years of meteoro-oceanic data statistics (for the preparation of contingency plans, particularly for offshore sites): OILMAP stochastic (RPS) ;
  • the dispersion in the atmosphere of a toxic cloud: ALOHA (NOAA) ;
  • the fate of a chemical spilled at sea, or even the quantity and concentration of pollutant in the various compartments (surface, water column and atmosphere): CHEMMAP (RPS).
