  1. DeepwaterHorizonOilSpill Startedthe 20th April Capped 15th July Permanentlysealed 20th September

  2. Whatcausedit? • Hydrocarbonsshot up and ingnitedcausingexplosion and fire in DeepwaterHorizonoilrig. • 1- Failure • 2- Loss of control of thepressureonthe fluid in thewell • 3- ¨Blowoutpreventer¨ (sealswell in event of loss of control) failedtoengage.

  3. ArealExtent • about 1,000 miles of shoreline had been affected. Of this stretch, about 200 miles were heavily oiled • http://www.guardian.co.uk/world/interactive/2010/apr/29/deepwater-horizon-oil-spill-map

  4. Effects • Environmental: • Harm done towildlife: • More than 6,100 deadbirds(2,200 visiblyoiled) • 153 deaddolphins(at least 8 smearedwithcrudeoil) • Sea bedaffected: - mounds of deadorganisms, including coral- oceanfloorcoated in darkbrownslimeabout 4cm deep • Bluefin tuna: dangerbecomingextinct, hatchthroughout time of spill • Whales, dolphins, needtosurfacetobreathe, shrimp, bluecrab, breedingseason in thespring, duringspill

  5. Effects • Economic : • 22.6 billion USD distributed by the company in response to cleanup costs, to displaced workers and businesses (production, processing and transport of oil), and affected state governments • 25 million USD given to the states of Alabama, Florida and Mississippi • 60 million USD used in the construction of barrier islands off the coast of Luisiana • 1.4 billion USD used in cleanup efforts • 6700 compensation claims filled • Lawsuits • 56-84 thousand barrels of oil released daily, money loss by the company • Diminished costumer confidence on the brand • Seafood industry damaged, increase in seafood prices • Chain reaction

  6. Couldithavebeenpredicted? • Marine OilSpills • Releases of crudeoilfromtankers, offshore platforms, drillingrigs and wells. • Spills of refinedpetroleumproducts (gasoline and diesesl) usedbylargerships. • Oilspillscannot be predicted. However, more control measurescould be applied in ordertominimizethishazardousaccident.

  7. Can oilsils be predicted in thefuture? • Oil spills can be prevented with a blowout preventer (BOP). • A blowout preventer is a large, specialized valve used to seal, control and monitor oil and gas wells. • Huge pinchers with blades close around the drill pipe and cut the oil spill off. • The ultimate prevention : • prohibit drilling and extraction anywhere near land • require double hulls before a tanker is allowed within a certain distance of land • reduce dependence on fossil fuels that have to be transported by water by as much as possible.
