Largest oil spill ever recorded Gulf of Mexico – Macondo Well Explosion and sinking of BP’s oil rig Explosion caused 11 deaths 94 survivors from rig crew Serious environmental problems arised
9-year-old Mobile, Floating Able to drill up to 3000m depth Owned by Transocean , Leased to BP High-pressure methane gas, ignited & exploded Crew rescued by lifeboats and helicopters Rig sank in 22 April 2010
Before After
BP estimated 1,000-4000 initially barrels flow rate/day FRTG estimated 20,000 – 40,000 barrels/day Total leakage: 4,9 million barrels ±10% Directly impacted 180,000 𝑘𝑚 2 of ocean 2000 km of coastline contaminated
Blow-out preventer failure Misreading pressure data by managers – defective cement job Mistakes in control routines Failure to observe and respond to critical indicators Risky cost cutting decisions not noticed by government regulators
Crew Rescue Operations U.S. Coast guards used 2 cutters, 4 helicopters and 1 rescue plane Firefighting Operations No specified plan, no preparation Many Attempts to Stop the Leakage Clean-up Operations
Attempt to close the blowout preventer FAILED Placing a 125-tonne containment dome over largest leak – FAILED Pumping heavy drilling fluids into the blowout preventer – FAILED The permanent solution: Drilling of relief wells to reduce the pressure in the main well. Cement pumping finally resulted and the well capped.
The well was effectively killed on September 19, 2010 Nearly 5 months of leakage
April 28 – U.S. Military joins the clean-up ◦ ◦ U.S. Government – Unified Command Structure BP, Transocean Federal Agencies: Minerals Management Service National Oceanic and Atmospheric Administration Environmental Protection Agency (EPA) Coast Guard Fish and Wildlife Service National Park Service Centers for Disease Control (CDC)
◦ 4 fundamental strategies Controlled Burns, Containment, Chemical Dispersal, Oil Removal
Total Response Vessels: 6,300 Total boom deployed: 1,500km Oily Water Recovered: 15+ million gallons Chemical Dispersant Used: 1.1+ million gallons Oil recovered: 10,5 million gallons Overall personnel responded: 37,000+
Environmental Effects on Gulf Ecosystem • Nearly 9,000 species of animals imposed o Fish, birds and other marine animals • • • Unexpected changes in the population of species o Destruption of habitats Increase in the concentration of carcinogens and chemical materials in ocean by 40 times o Genetically modified sea creatures have emerged The future effects could not be predicted
Environmental Effects on Human Life ◦ The biggest health crisis in coastal cities ◦ Water and air pollution ◦ Food Shortage ◦ Pollution created economical discolation for local people
What Was Wrong?
◦ ◦ ◦ ◦ ◦ An appliable crisis plan was not available Initial denial of responsibility Inconvenient behaviour of the CEO Misinforming the media Inappropriate relations with judges What Was Right?
◦ ◦ ◦ ◦ A good PR performance Live broadcast from the disaster location Using trustworthy people for the campaign The effective use of social media
