The 2010 Horizon Oil Rig Explosion
April 20th, 2010 an explosion occurred that created what would be considered one of the worst oil spills in U.S. history. The Deepwater Horizon Oil Rig was being leased by BP Oil Company and was located only about 40 miles off of the coast of Louisiana. A surge of natural gas that made its way to the Horizon rig’s platform ignited, causing the rig to capsize and sink, thus breaking risers that were being used to counteract the large amount of pressure from oil and natural gasses (Pallardy, 2015). The explosion killed 11 workers and injured 17 others and caused a massive leak in the oil wellhead. It took 87 days for the wellhead to be closed and it is estimated that over that time around 210 million gallons

The coast of the Gulf of Mexico is an extremely important habitat for a wide variety of migratory birds. When these birds come in contact with oil and other contaminates, they bring those contaminates to where ever they migrate to which can be as far as Alaska or South America (Tangley, 2010). Due to seabird’s susceptibility to the effects of oil, the amount of seabird deaths in the Gulf is easily in the hundreds of thousands and keeps growing (Balmer, 2014). Birds are especially affected by oil getting in their feathers. The oil causes the feathers to mat and loose its insulation capabilities, thus causing thousands of birds to die of hypothermia. Birds that are too heavily oiled end up too heavy to fly and will often lose their buoyancy causing many birds to drown (U.S. Fish and Wildlife Service, 2004). The birds can also easily ingest the oil and contaminates while trying to clean their feathers and even eggs were contaminated by compounds found in the BP oil (Pallardy, 2015). Oil ingestion in birds and mammals has been found to cause organ and adrenal damage, skin irritation and ulceration, immune system suppression, and changes to natural behavior (U.S. F.W.S., …show more content…
The dispersants were a substance that was supposed to break down the oil and make it easier for bacteria to be able to process the contaminates (Pallardy, 2015). The main dispersant used was called Corexit. The manufacturer of Corexit determined that it was safe to be used, however there has been a lot of controversy over the pros and cons of the dispersants and whether they were doing more damage than good (Kirby, 2013) Lab studies suggest that the dispersants had just as much of a negative effect on coral as the oil did by itself. The dispersants helped keep the oil from rising to the surface, however the combination of the oil and dispersants made the environment and welfare of the Gulf’s sea life even worse (Freudenburg & Gramling,
The explosion on the Deepwater Horizon oil rig that started it all killed 11 people and injured 17. On April 20, 2010, a
Massive cleanup efforts were initiated within a few weeks of the spill and they continued at reduced levels for the next three years. Approximately 14% of the spilled oil was recovered by cleanup crews (Newsweek, p.50). As a result of these efforts and natural weathering, little oil from the spill remained in the affected area by 1992. However, according to the National Oceanic and Atmosphere Administration some oil residues are still found under the ocean surface in areas sheltered from wind and waves. Yet, these residues are highly weathered and the toxicity is reduced to levels tolerable by organisms in the water (7). Nonetheless, the magnitude and timing of the Exxon Valdez oil spill raised immediate concerns about possible effects on marine fish and wildlife and prospects that these effects might be long lasting.
The Deepwater Horizon oil spill disaster that took place in the Gulf of Mexico in April 2010 is the largest oil spill to have ever occurred in USA waters. As efforts to hold the current spill continues, the higher chances of clean up damage compensation technique, and also enhancing prevention of future oil spill responses and recovery. The rig was owned and under the operation of Transocean, a Switzerland-based offshore drilling firm, and leased to BP plc, one of the biggest oil firms in the world. The explosion and fire that led to eleven fatalities and several injuries took place despite specialized oil spill prevention equipment also known as a blowout preventer, which is designed to avert such a kind of disaster. The quantity
On the Deepwater Horizon oil rig the largest marine oil spill occurred all caused by an explosion. The oil spill caused a “Colossal” damage to its surrounding environment. Spreading to the coasts of many states in the Gulf of Mexico, such as Louisiana, Mississippi, Alabama, and part of Florida's. The people living in these coast are stakeholders of the Deepwater Horizon oil spill. Said it is “The oil well over which it was positioned was located on the seabed 4,993 feet below the surface and extended approximately 18,000 feet into the rock,” (Pallardy, 2016). Still collapsed erupting into and
The Deepwater Horizon Oil Spill occurred on April 20, 2010 in the Gulf of Mexico. This oil spill was the largest spill in history in front of the Exxon Valdez oil spill of 1989. This oil spill released about 4.9 million barrels of oil into the ocean. This spill not only wreck havoc on the marine life but also the economic players that depended on ocean such as fisherman, tourism, and offshore drilling located along the gulf coast. Along will the spill the oil rig which was named Deepwater Horizon also went up in flames. This proved that the issue went far beyond just an oil rig that blew a line. Since this oil spill had drastic impacts all along the coast, BP which was the most liable for this incident faced criminal charges based on what happened. BP which knew the risks of deep ocean drilling failed to take the necessary safety procedures to reduce the risks of such incident occurring, thus was the reasoning behind placing most of the fault on them and not the other companies. The lack of regulatory oversight led to the issues and cost-cutting procedures opened the rig up to possible malfunctions like the one that occurred. During the spill into the gulf, BP sealed the well with cement which seemed to stop a majority of the oil from escaping the well. BP also recognized that the well was “dead” which was proven wrong when scientists still could conclude was leaking minor amounts of oil into the ocean. This spill not only proved to be harmful to the environment but also
Going to the water was a hazard and they starved or was covered in the oiled
The oil also has a physical and physiological effect including irritation, inflammation, or necrosis of the skin, chemical burns, ingestion of oil/dispersants can lead to inflammation, ulcers, bleeding, as well as possible damage to liver, kidneys, and brain tissue. It can also cause disfunction of the immune and reproductive system. The wildlife can become physiologically stressed, their physical condition will ultimately decline, and some may even die. The oil spill has additionally had an extensive effect on the ecosystem as a whole. An ecosystem can be defined as a biological environment consisting of all the organism living in a particular area, as well as the non-living physical components of the environment with which the organisms interact. Experts predict that the ecosystem could require years or even decades to fully recover since there is a chance of biomagnification. Biomagnification occurs once a PBT(Persistent Bioaccumalative substances) have piled up in one part of the ecosystem the substance becomes concentrated from one link in the food web to the next. It can affect entire populations and threaten biodiversity in “insidious, sub-lethal” ways. In addition to the possibility of biomagnification the oil causes
The BP oil spill was one of the worst oil spills to ever happen in the US. There are many factors that caused this horrible spill to happen; to be exact there were eight failures of the oilrig that caused this disaster. The first failure was the cement at the bottom of the borehole was not sealed properly. This caused the oil and gas to start leaking into the pipe leading to the surface of the rig. The second failure was that the valve leading to the surface was sealed improperly with cement. In addition, there were two mechanical valves, which failed to stop the leak of gas and oil. The crew was also to blame because they did pressure tests, which they did not read properly. This made the crew believe the oil well was under control when it was not. The crew also did not spot the leak before the explosion; there was an increase in pressure inside the well fifty minutes before the explosion but the crew did not interpret it as a leak. Next, about eight minutes before the rig exploded, mud and gas began to come out onto the floor of the rig. The crew tried to stop this by activating the blowout preventer, which is at the top of the well, however this caused the blowout preventer to malfunction. The rig had side vents that were suppose to release this mud and gas, but instead it was diverted to a device that separates only small amounts of mud and gas. This device quickly became overwhelmed and flammable gas was sent all over the rig. The alarm on the rig should have sounded
On April 22 2010, the World faced one of its worst oil spill disasters in the history of marine petroleum exploration. A deadly oil well blowout at Macondo Prospect, about 41 miles off the southeast coast of Louisiana, spewed huge quantities of oil for 87 long days causing major environmental and economic troubles to the Gulf region ("Gulf of Mexico Oil Spill"). It started with a fire and explosion, killing 11 workers, and then unleashed a slow motion disaster that spread across the 600 mile gulf coastline. The massive oil spill disrupted lives and livelihoods, and swallowed up the habitat of many species, leaving their fate to the toxic mix (“Political and environmental Dilemma”).
The damage caused by the spill is almost immeasurable; ecological, political, economic, social it almost devastated the U.S. Gulf Coast fishing and tourism industries. Even in January 2011 a report was made by oil-spill experts from the University of Georgia stating that tar balls continue to wash up on beaches, collect in shrimp nets, kill marsh grass, and even undegraded oil in the seabed (Dykes, 2011). It will likely be years, if not decades, before the final assessment of damage, short-term and long-term, is accurately noted from this disaster.
The oil from the wells that was released into the Persian Gulf killed tens of thousands of birds and threatened numerous marine animals.
For instance, Rufe, who is a scientist, states that we have not developed an approach that can clean more than 3 to 5 percent of the spilled oil” (Mufson, 2012). Furthermore, In the Gulf of Mexico, although 205.8 million gallons of oil have been spilled, just 51.8 million gallons have been collected, which equals approximately 25 percent. Moreover, in order to clean the Gulf from the oil spills almost 2 million gallons of toxic dispersants were used. Unfortunately, the toxic dispersants did not truly purify the spilled oil, but fractured them into tinier particles. As a consequence, that may make the oil more harmful for some ocean animals and plants ( A Center for Biological Diversity Report, 2008). However, with the increasing of offshore oil drilling accidents, and with no solution to solve the problem efficiently. The hazardous impact is not going to affect only on animals and plants. It might affect people who depend on the polluted area for food, ecological enrichment, and entertainment ( A Center for Biological Diversity Report,
Over 8000 animals were reported dead 6 months after the spill, including many that were on the endangered species list (7). Subsequently, seafood prices increased affecting restaurants and supermarkets. People abstained from going to beaches covered in oil, water sports and other aquatic attractions which meant that all organisations involved in tourism such as hotels, tour operators, restaurants and boat rental companies were affected (1). Furthermore, the method of cleaning up the oil by “in-situ burning” (burning oil in a contained area on the surface of the water), had adverse effects on the environment as the burning off of the oil led to mutations and increased mortality due to pollution.
British Petroleum spill occurred in the Gulf of Mexico on April 20, 2010. The explosion occurred in the Deepwater Horizon oil drilling rig resulting eleven deaths that were employees and 17 injuries. According to The 2010 Deepwater Horizon Oil Spill: The Trauma Signatures of an Ecological Disaster, “over the subsequent period of 87 days, before the wellhead was successfully capped on 15 July 2010, more than 4.9 million barrels of petroleum (210,000,000 Us
over 8,000 animals(birds, mammals, turtles) were reported dead just 6 months after the spill, including many that were already on the endangered list. In the months following the Gulf oil disaster, wildlife managers, rescue crews, scientists and researchers saw many impacts of the oil impacting wildlife. Oil coated birds’ feathers caused birds to lose their buoyancy and their ability to regulate body temperature. Mammals could have ingested oil, which can cause ulcers and internal bleeding. Sea turtles were covered in oil as well. Nearly half the dolphins studied were very ill. 17% of the dolphins were not expected to survive. Since the spill, each year roughly 500 sea turtles are found stranded. The Gulf oil disaster hit at the peak breeding season for many species of fish and
