WP2 Definition of operational conditions • Accidents Causes & Condition • Spill Properties • Location • Environmental Conditions • Consequences-Potential Impact
Accident Causes and Conditions M/V Accidents Classification • Condition of Oil Tanks • Hull Condition • Amount of Oil to be Extracted • Age of Vessel and Shipwreck • Leaks • Cargo Shift & Capsizing • Grounding • Fire • Steering
Oil Density at 285 K Spill Properties • Oil type • (crude, diesel, kerosene, heating oil) • Oil properties at wreck temperature • (rheological properties, density) • Leaking rate • Amount of oil spilt
Location Mediterranean • Risk Analysis of European Waters Baltic Atlantic Coast • Identification of main searoutes in the aforementioned sites • Identification of accident locations
Disasters with major environmental impact happen almost every 2-3 years M/V Accidents of Interest • AMOCO-GADIZ 1978 • TANIO 1980 • AEGEAN SEA 1992 • ERICA 1999 • PRESTIGE 2002
Ship Accidents Population (251) Tanker Ship Accidents (30) Location II: The Baltic Sea Example Ship Accidents Causing Oil Pollution (71) Classification Dates : 1989-1999 Location :The Baltic Sea
Environmental Conditions Seawater & Climate Related Parameters Shipwreck Related Parameters • Water Currents • Water Temperature • Water Salinity • Surface waves • Wind • Depth • Sea-Bottom Profile
Low recuperation cost Profit from recuperated oil sale Lower ecosystem cleaning cost Prevention of damage in the tourism, fishing and other industries. Consequences-Potential Impact • Economical Consequences Pollutants Reduction • Environmental Consequences Higher Survivability Probability of Ecosystems after an accident
