Content Oil Spills Globally - trends Oil Spills in the Baltic The fate of the oil Environmental impacts 15/11/2018 May 2004
The Issues What makes the Baltic different? What environmental impacts can we expect? What will the clean-up of a spill cost? 15/11/2018 May 2004

Risk for spills increase 2000 ships at all times Doubling of annual cargo transport by 2017 Soon doubling of oil transport compared to 1995 15/11/2018 May 2004
Baltic characteristics Low temperature Limited water exchange Extensive archipelagos 15/11/2018 May 2004
Figure 15: Fate of oil spilled at sea showing the eight main processes that cause oil to weather (ITOPF, 2002). 15/11/2018 May 2004

Fate of spilt oil in the Baltic Weathering is slow Degradation minimal Emulsification limited 15/11/2018 May 2004
The result More oil on the surface of the sea More oil on the shores More damage to seabirds/waders Less damage to sub-surface life 15/11/2018 May 2004
A spill in the Baltic: May threaten endangered species (guillemot, razorbill, long-tailed duck, greater scaups, smew) and ecosystems (e.g. saltmarshes with waders) May contaminate large distances of shoreline (hundreds of km) May cause long-term contamination (several years) May affect the ecosystem over extended periods (several years) 15/11/2018 May 2004
What This Means The Baltic is particularly sensitive to oil spills Spills here cause more damage to shorelines, animals and ecosystem Spilt oil will remain a threat for longer periods time 15/11/2018 May 2004
A spill of 25,000 tons Will affect several thousand km of shoreline Will affect several thousand seabirds Will cause impact on the littoral ecosystem Will affect toursim Will affect fisheries Will affect quality of life Infrastructues Employment 15/11/2018 May 2004
A spill of 25,000 tons 15 vessels 100,000 E/day Air surveillance 800 E/day Equipment, booms Total 10 million E 80,000 man-days for shore clean-up = 25 million E Waste handeling 150,000 ton = 10 million E 15/11/2018 May 2004
Total Cost Tourism 160 milj E Fishing 17 milj E Jobs + Property values - Quality of life - Accidents - Cost for the state 50 milj E 15/11/2018 May 2004
Action Minimize risks for spills by separating traffic, monitoring vessels, ensure highest standard of ships and manpower (EU Directive and IMO PSSA) Identify and develop “Places of Refuge” (EU Directive and IMO Guidelines) 15/11/2018 May 2004
