Deep Water Horizon
Slide 1
57 spills with volumes estimated at ³ 11,000 MTs since mid-1960s
Exxon Valdez is smallest of this group, but is most well know for coastal impacts
2 largest ‘spills’ are multiple events during recent armed conflicts
Persian Gulf War in 1991
Chechnyan insurrection in 2000
72% are from tankers
7% each from wells and storage tanks
3% pipelines and cargo vessels
1 lone refinery
Although Valdez is #57 on this list, it probably top 5-10 in environmental damage and #1 political damage.
Most infamous are those where oil stranded on shorelines
Slide 5
Model provides Business Units with guidelines for mounting an appropriate field response and managing issues.
Tier 1
Accidental discharges occurring at or near a vessel or facility as a result of disruption in routine operations. Impacts are low and in-house response capability is adequate.
Examples of Tier 1 Spills:
• Overflow of sumps or oil-water separators
• Leakage or overflow of tanks
• Leakage from valves, pipelines or transfer hoses
• Accidental discharge of bilge water from vessels
• Tank truck/tank car rollover near water
Tier 2
Medium-size spills occurring within the vicinity of vessel or facility as a consequence of a non-routine event. Significant impacts are possible and external (regional) support for adequate spill response, e.g., assistance from a local spill cleanup co-operative, is required.
Examples of Tier 2 Spills
• Cargo loss due to tanker grounding, collision, or system failure
• Rupture of a sub-sea pipeline
• Spills due to fire or explosion at a terminal or on a tanker
• Spills due to sabotage, natural disaster, or blowout
• Tank collapse near water
Tier 3
Large spills occurring either near or remote from a vessel or facility as a result of a non-routine event, requiring substantial resources and support from national or worldwide spill co-operatives to mitigate effects perceived to be wide-reaching, i.e., spills of national or international
