Oil pollution is one of the most disastrous forms of environmental damage. Oil spills can harm wildlife, ruin beaches, and make seafood unsafe to eat. Oil spills are often caused by operational releases from vessels, which as of 2007, were estimated to account for 21% of oil releases from vessels. Other causes include accidents involving oil tankers, leaks during oil extraction, illegal tank-cleaning operations at sea, and discharges into rivers. Oil pollution can also result from runoff oil on roads, which is then washed into the ocean during rainstorms. While the frequency and volume of oil spills have decreased over the years, the problem of oil pollution remains a significant challenge with far-reaching consequences for the environment and human health.

What You'll Learn
Oil tanker accidents
Another notable incident involving an oil tanker accident occurred in 2014 when the barge E2MS 303 collided with a towboat on the lower Mississippi River. This accident resulted in the leakage of 750 barrels of Bakken crude oil into the river. Oil spills can also occur due to drilling accidents, such as blowouts or wellhead failures, or from natural causes like earthquakes or underwater volcanic eruptions.
The impact of oil spills on wildlife can be devastating. Oil destroys the insulating ability of the fur of mammals like sea otters and the water-repelling abilities of birds' feathers, exposing them to harsh elements. Additionally, birds and animals may ingest oil when attempting to clean themselves, leading to poisoning. Oil spills can result in the death or injury of thousands of birds and mammals, highlighting the importance of effective emergency response protocols and clean-up efforts.
To address the risk of oil tanker accidents, it is crucial to implement measures such as continuous crew training and the use of double hulls in tankers, which contribute to a higher level of safety. By understanding the causes of oil spills and improving accident probability assessments, we can enhance pollution prevention strategies and mitigate the environmental, ecological, and socioeconomic consequences of oil pollution.

Drilling accidents
One of the most severe types of drilling accidents is a blowout, which happens when the pressure control systems fail during drilling. This results in an uncontrolled release of oil and gas from the well, leading to significant oil spills. Blowouts pose serious safety risks, including the risk of drowning if the rig collapses into the sea. Other drilling accidents can be caused by weather conditions, equipment malfunction, maintenance issues, or a lack of safety equipment.
Accidents involving tankers, barges, pipelines, refineries, drilling rigs, and storage facilities are the most common cause of oil spills. For example, in 2014, a barge collided with a towboat and leaked 750 barrels of crude oil into the Mississippi River. Oil spills can also occur during the transfer of oil between vessels or between vessels and storage facilities due to equipment failures, human errors, or sudden shifts in cargo.
Oil spills from drilling accidents can have far-reaching impacts. Oil spreads rapidly across the water surface, forming a thin layer called an oil slick. This oil slick can harm marine birds and mammals, making it difficult for them to regulate their body temperature and causing poisoning if ingested. Oil spills can also contaminate seafood, ruin beaches, and disrupt tourism and commerce.
Additionally, oil spills from drilling accidents can have economic repercussions. The clean-up process requires expensive and time-consuming management, and the environmental damage can impact industries such as tourism and fisheries. Oil spills can also affect utilities that rely on seawater, such as power plants.

Natural seepage
Oil spills are a significant environmental concern, wreaking havoc on ecosystems, wildlife, economies, and human health. While most spills are caused by anthropogenic factors, natural seepage from the ocean floor is a notable contributor.
Underwater volcanic eruptions can also lead to the formation of oil slicks on the water's surface. The intense heat and pressure cause hydrocarbons to escape and create a thin layer of oil, known as a sheen, which can often appear rainbow-like. While natural seepage contributes to oil pollution, it is important to note that the impact is relatively small compared to anthropogenic sources.
In addition to natural seepage, there are other natural causes of oil spills. Climate factors and natural disturbances, such as hurricanes or strong storms, can contribute to oil spills, particularly in areas with oil drilling and transportation infrastructure. These natural events can damage equipment, pipelines, and storage facilities, leading to accidental releases of oil.
While natural seepage and other natural factors play a role in oil pollution, it is essential to recognize that human activities are the predominant cause of oil spills. Oil spills can occur during the extraction, transportation, or use of oil, and they have severe environmental and economic repercussions. The impact of oil spills on wildlife and ecosystems can be catastrophic, requiring swift and effective emergency response protocols to mitigate the damage.

Poorly maintained vessels
The impact of oil spills from poorly maintained vessels can be devastating, especially when they occur in ecologically sensitive areas such as beaches, mangroves, and wetlands. Oil spills harm marine life, including birds and mammals, by destroying their natural insulation and water-repelling abilities. Ingesting oil during cleaning attempts can also poison these animals.
In addition to ecological consequences, oil spills from poorly maintained vessels can have economic repercussions. Tourism and commerce can be severely affected, as can power plants and other utilities that rely on or discharge into seawater. The clean-up process is expensive and time-consuming, requiring specialist contractors and careful management to prevent further spread.
To address this issue, it is crucial for entities involved in oil transportation to diligently maintain and monitor their vessels. Regular inspections and proactive maintenance can help identify and rectify issues before they lead to structural failures and oil spills. Additionally, compliance with regulations, such as the MARPOL convention, which governs operational discharges, is essential to mitigate the environmental impact of vessel operations.
While the frequency of oil spills from operational discharges has decreased over time, the impact of each incident remains significant. As such, ongoing efforts to improve vessel maintenance, implement preventive measures, and enhance emergency response protocols are vital to reducing the environmental and economic toll of oil spills from poorly maintained vessels.

Operational releases
Oil spills from vessels can also occur during the transfer of oil between vessels or between vessels and storage facilities. Accidents such as equipment failures, human errors, or sudden shifts in cargo can cause these spills. Additionally, oil transfer through pipelines can be disrupted due to ruptures caused by corrosion, ground movement, or construction-related accidents.
Recreational boats can contribute to operational oil spills due to human error or unpreparedness. While these spills are typically small, they can be challenging to track due to underreporting. Oil from land-based sources, such as runoff oil from roads, can also reach oceans through rivers or rainstorms, impacting coastal ecosystems.
Ports are particularly susceptible to operational oil spills due to the large volume of boats entering and leaving. These spills may have damaging economic repercussions and require expensive and time-consuming management. It is crucial to carefully manage boats during and after a spill to prevent further spread and ensure that oil does not become a continual source of contamination.
