Edit Did You Know? Goofs During the movie, several views are made of the moon pool, where the riser top is supported by the Riser Tensioner cables.
On a Semi Submersible rig, the Riser is anchored to the top of the BOP, on the seabed, and thus fixed with regards to the floating Rig.
Most previous spills had been single events—for example, the grounding of an oil tanker and the rapid release of the petroleum on board.
The Deepwater Horizon accident had left the wellhead gushing oil constantly, and because the rupture was about 1. As the oil began to reach the surface, responders turned to a familiar line of defense in oil-spill cleanup: dispersants.
These proprietary solutions contain many compounds, including surfactants, emulsifying agents, and solvents. Once sprayed on an oil slick, the dispersants act like a detergent and break the oil into smaller droplets that can then mix into the water, where oil-eating microbes can degrade it.
Using dispersants offshore can reduce the amount of oil that washes onto the beaches, protecting both people and fragile coastal ecosystems, Overton says.
But the use of the chemicals has been controversial since they were first deployed in large quantities in the Torrey Canyon spill off the southwest coast of Great Britain.
The dispersants wreaked massive environmental damage, decimating marine organisms including seaweed, plankton, and mollusks. Later analysis revealed that ecosystems in areas treated with the chemicals recovered up to five times as slowly as those that were not.
And although the formulations of dispersants have changed significantly in the decades since that spill, many people are still wary of their use.
There, the oil could eventually be metabolized by microbes, settle to the ocean floor, or get carried out of the Gulf entirely.
This approach might also help improve the air quality for response workers on the surface by trapping in the depths some compounds that would have volatilized.
But all existing tests on the efficacy of dispersants had been conducted on the surface of water, says Elizabeth Kujawinski, a chemical oceanographer at Woods Hole Oceanographic Institution.
There was no guarantee that they would perform the same way in the crushing depths of the ocean. Related: Reckoning With Oil Spills. Despite these safety and efficacy concerns, the US Environmental Protection Agency authorized the first-ever subsurface use of dispersants on May 15, Eventually, engineers pumped almost 3 million L of two Corexit formulations below the surface of the Gulf.
Aircraft and boats sprayed another 3. Of that amount, about half made it up to the surface Proc. Many of the light hydrocarbons, which are highly soluble in seawater, dissolved in the water column.
And much of the rest of what was released formed deep plumes of oil that eventually stretched more than 32 km from the gushing well—an indication, perhaps, that injecting the dispersants at depth had prevented some oil from reaching the surface.
But the presence of the deep-sea plume did not convince some researchers that the dispersants had done their job. The size and shape of the hole in the well, as well as the large amounts of natural gas in the fluid inside the Macondo reservoir, may just as easily have caused the oil to atomize and form a plume, says Claire Paris-Limouzy, a biological oceanographer at the University of Miami.
That was more catastrophic than not using anything. The dispersants also affected the crews that helped clean up the spill. According to surveys of spill-cleanup workers, many who had been exposed to dispersants showed symptoms related to the chemicals, such as skin irritation and respiratory problems, several years after the spill.
More than half the exposed workers experienced skin irritation; about a quarter reported a cough or burning eyes or both Environ.
Health Perspect. A whistleblower report published by the Government Accountability Project in April documents ongoing health problems in response workers.
In her studies using the model organism Caenorhabditis elegans , Pan has found that both crude oil from the Macondo reservoir and Corexit A inhibit reproductive function, especially when exposure occurs during development.
And a mixture of crude oil and dispersant is much more toxic to C. Another study that looked at toxicity to a key plankton species found that the dispersant-oil mixtures were more than 50 times as toxic as oil alone Environ.
Where the response went wrong, he says, is in not collecting crucial data, such as air-quality measurements, that could have informed whether the solutions were working as hoped.
Researchers have known that a variety of so-called weathering processes, both natural and human driven, transform and degrade the hydrocarbons in oil over varying timescales on the surface of a body of water.
The most volatile components, such as low-molecular-weight alkanes, evaporate off almost immediately. Oil that is dispersed—either naturally or chemically—is mixed into the water column, where hydrocarbon-degrading microorganisms metabolize it.
Some oil sitting on the surface mixes with seawater to form viscous, sticky emulsions. And some fraction of the oil is transformed into partially oxidized compounds by photochemical processes.
And these reactions were thought to occur in the weeks or months after a spill, after much of the oil had already been cleaned up by other means.
Contact us to opt out anytime. Furthermore, the researchers showed that these reactions likely occurred in the hours and days after the oil reached the surface, with two-thirds of the oxidation occurring within the first 10 days of exposure Environ.
Rather than directly photooxidizing, much of the crude oil had been oxidized by the highly reactive oxygen-containing radicals produced when PAHs or other crude oil compounds absorb sunlight—a process called indirect photooxidation.
Limitations in the equipment used by previous generations of analytical chemists hampered their efforts to understand these products. But advances in high-resolution mass spectrometry and new ionization techniques allowed scientists studying the Deepwater Horizon spill to begin to understand the high-molecular-weight materials that make up these deposits.
Using that 3-D model, they found that how far PAHs and other toxic compounds spread in the Gulf was likely much larger than the visible extent of the spill as captured by satellite and aerial imagery.
The new model suggested that toxic oil products reached beyond the area that had been closed to fishers to prevent them from picking up fish contaminated by such compounds.
And the organisms did so with remarkable speed, says Joel Kostka, a microbial ecologist at the Georgia Institute of Technology. As a result, those areas contain remnants of the blowout.
When big storms move through the Gulf and churn up the seafloor, tar balls and other oil residues still wash up on the shores.
Because the Gulf of Mexico has so many natural hydrocarbon seeps, researchers suspected that the microbes endemic to the Gulf might be well adapted to metabolize the leaking fuel—that the body of water was primed for a spill.
And indeed, the microorganisms responded rapidly to the injection of natural gas and crude oil. Among those rules was one that required blowout protectors—the piece that had failed at Deepwater Horizon—to be inspected by a third party, rather than self-certified by the drilling companies.
But many of those rules, as well as other safety practices put in place after the disaster, have been weakened in recent years.
Most notably, in the Trump administration finalized rollbacks of several components of the rules, including the independent safety certification for blowout protectors and bi-weekly testing.
Today, more than 50 percent of Gulf oil production comes from ultra-deep wells drilled in 4, feet or more of water, compared with about 4, feet for Deepwater Horizon.
The deeper the well, the more the risk: A study showed that for every hundred feet deeper a well is drilled, the likelihood of a company self-reported incident like a spill or an injury increased by more than 8 percent.
After the Exxon Valdez spill, for example, new laws and regulations were enacted to deal with future tanker spills. Another concern, says Scott Eustis, the science director at the Louisiana-based Healthy Gulf, a group that focuses on marine protection, comes from the ever-increasing pressures of climate change.
Louisiana, which has the most comprehensive climate adaptation plan in the region, is expecting the number and intensity of major hurricanes to increase within the next 50 years.
Each storm that blows through the Gulf threatens offshore drilling infrastructure. But scientists realized they lacked much of the basic background science necessary to predict where, when, and how the oil would spread or what its impacts on the region would be.
At first, it was difficult even to assess how much oil spilled from the well. Early initial assessments were low—but satellite imagery revealed that there was much more oil than had been reported.
The final tally showed that the spill dumped more than million gallons of oil. Oil continued to sink to the ocean floor for more than a year, a recent study shows.
It changed the amounts of sediment collecting on the bottom of the sea for years afterward and choked them of oxygen.
Immediately after the spill, the 1, miles of contaminated coasts saw oil concentrations times higher than background levelsl even eight years later , concentrations were 10 times higher than before the spill.
And In February of this year, a study showed that the footprint of the oil spread some 30 percent wider than previously estimated, potentially contaminating many more fish communities than previously thought.
Studies are also showing that reef fish changed drastically after the spill; that fish absorbed some of the oil-sourced contaminants ; and that ecological communities throughout the water column, from tiny bacteria to deep sea corals to arthropods , could take decades to recover.Mehr zum Thema.
