TESEO: Oil spill modelling

TESEO is a numerical model to simulate the transport and weathering of oil spills in the marine environment as well as trajectories of floating objects and person in water. The model has been developed by IHCantabria in the framework of different projects, as ESEOO project (2004-2006), funded by the Spanish Ministry of Science and Technology. 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 model consists of a transport and a weathering module to represent the evolution of oil spilled in the marine environment. The transport module derives from the model developed by IHCantabria as part of the operational forecasting system created to respond to the Prestige oil spill (Galicia, 2002). The weathering module takes into account the main physical and chemical processes at local (harbours, bays and estuaries) and regional scale (offshore). Forcing data (wind, currents and waves) required by the oil spill model are provided by several national and international met-ocean operational systems and are available in Near Real Time to TESEO by FTP. The model provides in real time short-term (2-5 days) oil spill trajectories and weathering forecasting and backtracking to determine the likely spill site position.


TESEO has been used during Don Pedro oil spill (Eivissa Island, Spain, 2007), during oil spill incidents in marine oil and gas facilities and to develop oil spill management systems at regional scale (offshore) and local scale (bays, harbours and estuaries). Moreover, the model has been applied in different oil spill exercises carried out by the Spanish Maritime Safety and Rescue Agency in the Mediterranean Sea (Exercises "Baleares 2005", "Tarragona 2008"), and the Atlantic (Exercises "Gijón 2006", "Finisterre 2006", "Gascogne 2007", "Vigo 2007" and "Santander 2010"). The model has been extensively calibrated and validated with drifter buoys exercises (e.g. Gulf of Biscay, North Sea, Belfast Lough, Huelva’s Estuary and Algeciras Bay) and laboratory tests carried out by CEDRE in the framework of SPRES project (2012-2014, Interreg, Atlantic Area).
