TESEO – Modelo de Simulación de Transporte de Hidrocarburos

The TESEO model has been developed in the framework of the ESEOO project for the simulation of oil spill transports and fate processes as well as trajectories of floating objects. The numerical model has been integrated in a user friendly operational system in order to provide useful information for the decision-makers in a crisis situation. The combination of the numerical model and the graphical user interface constitutes the TESEO system.

The numerical model takes into account the transport and fate of oil spilled in the marine environment. These processes are simulated by means of two different models: a Lagrangian transport model and a weathering model. Forcing data required by the oil spill model are available in Near Real Time in the framework of the ESEOO project. At the present time, waves, wind and currents data are daily provided by Puertos del Estado (Spanish State Ports public agency) and by the Spanish Meteorological Agency. Meteorological and oceanographic operational models are run every day in these institutions and data are available to the TESEO system by FTP.

Applications

The performance of the TESEO model has been successfully tested during five operational oil spill exercises ("Baleares 2005", "Gijón 2006", "Finisterre 2006", "Vigo 2007" y "Tarragona 2008") organized by the Spanish Maritime Safety and Rescue Agency (SASEMAR) with the collaboration of the ESEOO Group. During the exercises, a mock oil spill accident and an at sea rescue and marine pollution response were simulated. An operational procedure was implemented to provide information in order to help the decision-makers in the emergency response and in the operations planning. Using the TESEO system, the scientific support group (USyP) provided forecast spill trajectories and fate processes to decision-makers in real time. The exercises showed the TESEO system capability as a useful tool in an oil spill response.

Case studies

The figure shows the comparison between the buoy path (orange circles) and the predicted trajectory (red circles) performed with the TESEO model during the Exercise "Finisterre 2006". As can be observed, a good agreement was found between the actual and predicted trajectory performed with the TESEO model.
