Mediterranean Decision Support System for Marine Safety (MEDESS-4MS) was dedicated to the strengthening of maritime safety by mitigating the risks and impacts associated to oil spills. MEDESS-4MS capitalised on existing pan-European frameworks and embraced recent advances and important developments  in oceanography in the Mediterranean area. MEDESS-4MS delivered an integrated operational multi model oil spill system in the Mediterranean by gathering and analysing met-ocean data as well as data related to ship traffic, ship operations and sensitivity mapping. This data is provided to well established oil spill monitoring and forecasting systems, thus, providing an invaluable tool regarding the early detection and efficient control of the oil spill at early stages.

Therefore, MEDESS-4MS offered a comprehensive and integrated multi-model approach regarding our response to oil spills at sea; an approach that takes into account all three important aspects related to marine pollution, that is, Prevention, Detection and Control. The beneficiary countries of MEDESS-4MS were Cyprus, France, Greece, Italy, Malta, Montenegro and Spain.
