Case-studies: Application in European waters

Case-studies of real spill incidents and the application of EU-MOP on:

•Strategic Level•Tactical Level •Operational Level

have been analysed for real spill incidents in:

•Spanish waters (Sierra Nava incident)•Greek waters (Nordland incident)•UK waters (Tenby Harbor incident)

Next, the Spanish and Greek case-studiesare briefly presented


Strategic Level Analysis: South of Spain (broader risk area)
