Ocean Oil Pollution: Strategies For Mitigation And Prevention

Oil pollution in the ocean is one of the most devastating yet preventable forms of pollution. Oil spills are extremely harmful to people, plants, and wildlife as they destroy marine ecosystems. Oil spills can be caused by large marine traffic like tankers and barges, or small privately owned boats. In fact, in some places, the largest source of oil pollution comes from small vessels. While massive spills like Deepwater Horizon have devastating consequences, most oil pollution results from everyday human errors or carelessness. To reduce oil pollution in the ocean, preventative measures must be taken, and effective preparedness and response strategies must be in place.

Prevent oil spills from reaching the shore

Preventing oil spills from reaching the shore is a critical step in reducing oil pollution in the ocean. Here are some detailed strategies to achieve this:

Boom Deployment:

• Booms are long, floating barriers that can be used to contain and divert spilled oil away from the shore.
• They are effective when weather conditions are favourable, i.e., when winds and waves are not too high.
• Booms help to concentrate the oil, making it easier to recover using skimmers or burning it off.

Dispersant Application:

• Dispersants are chemical agents, similar to soaps and detergents, that can be applied to the spill via aircraft or specialised boats.
• They are effective for breaking up light or medium-density oils into very small droplets that can dilute throughout the water.
• Dispersant use is weather-dependent, as high winds make accurate application difficult.
• While dispersants do not remove the oil, they make it more biodegradable and reduce the impact on sensitive habitats.

Vessel Maintenance and Preparedness:

• Boat owners and operators can play a significant role in preventing oil spills by maintaining their vessels properly.
• This includes staying on top of maintenance and being cautious during refuelling to avoid spills at marinas.
• Planning for emergencies, such as severe weather events, by creating a disaster preparedness plan, removing vessels from water if possible, identifying safe harbours, and checking anchors and lines, can also reduce the risk of spills.

Reducing Oil Dependence:

• Oil spills occur due to our reliance on oil, so reducing our dependence on it can lower the risk of future spills.
• This can be achieved by opting for alternative modes of transportation like biking, walking, or taking public transportation instead of driving.
• By using less oil, we decrease the amount that needs to be transported, reducing the chances of spills.

Shore Protection:

• When oil reaches the shore, it can be challenging to remove.
• Sorbents, which absorb oil but not water, can be used to contain and recover oil that has reached the shoreline.
• In some cases, controlled burning, or "in situ burning," of oil on the water's surface or marsh vegetation may be performed to prevent it from reaching the shore.

Reduce the impact of oil on marine life

Oil pollution is one of the most devastating forms of pollution, with serious consequences for people, plants, and wildlife. Oil spills are often the result of human error or carelessness, and fuel oil usually enters the water during the refueling of vessels. Oil from recreational boats can also come from dirty ballast water, oil tank washings, and bilge water.

The impact of oil spills on marine life can be reduced by taking preventative measures and responding quickly and effectively when a spill occurs. Here are some ways to reduce the impact of oil on marine life:

• Preventing spills: Boat owners and operators can reduce the risk of oil spills through proper vessel maintenance and planning for emergencies. This includes regularly inspecting and maintaining engines and fuel tanks, as well as taking precautions during refueling, such as using oil absorbent pads and avoiding overfilling fuel tanks.
• Quick response: When a spill occurs, it is important to act quickly to contain and clean up the oil. Booms, skimmers, and sorbents can be used to contain and recover spilled oil. Dispersants can also be used to break up the oil into small droplets, which can then be biodegraded more easily.
• Minimising use: Reducing the use of oil can lower the risk of future oil spills. This can be done by opting for alternative modes of transportation, such as biking, walking, or taking the bus, instead of driving.
• Proper disposal: Used oil and fuel-absorbent materials should be properly disposed of to avoid adding to pollution. Recycling used oil and filters is also important.
• Collaboration: Governments, municipalities, and corporations all have a responsibility to work together to prevent and mitigate the impacts of oil spills. This includes enforcing regulations, such as the Oil Pollution Act of 1990, which holds the responsible party accountable for cleanup operations and restoration of natural resources.
• Education and awareness: Raising awareness about the impacts of oil spills on marine life and promoting best practices for prevention and response can help reduce the frequency and severity of spills.

Speed up the degradation of unrecovered oil

The degradation of unrecovered oil can be sped up by using booms to contain or divert the oil, which can then be recovered using skimmers or burned off. However, this is weather-dependent, as high winds and waves can cause booms to be ineffective. Dispersants, which are chemical agents similar to soaps and detergents, can be used to break up oil slicks into very small droplets, which are more easily biodegraded. This method is also weather-dependent, as high winds can make it difficult to accurately target the spill.

Dispersants are sprayed onto spills by specially equipped boats or planes. They do not remove the oil but help to break it up into smaller particles, which dilute throughout the water. This provides a measure of protection for sensitive habitats threatened by a surface slick.

The rate of oil degradation can be increased by higher temperatures, exposure to sunlight, dissolved oxygen, nutrients such as nitrogen, phosphorus and potassium, shoreline energy, and diverse hydrocarbon-degrading microorganisms.

Reduce oil pollution from boats

Oil pollution from boats is a significant problem, with small privately owned boats and marinas contributing the most to day-to-day oil pollution. In some places, such as the state of Washington, small vessels accounted for 75% of the oil spilled in local waters between 2006 and 2016. Therefore, it is crucial to take steps to reduce oil pollution from these sources.

One way to reduce oil pollution from boats is to ensure proper vessel maintenance. This includes regularly tightening bolts and hoses on the engine to prevent oil leaks, as well as replacing cracked or worn hydraulic lines and fittings before they fail. Outfitting the engine with an oil tray or drip pan can also help catch any oil leaks. In addition, creating a bilge sock out of oil absorbent pads can prevent oily water discharge.

Another important aspect of reducing oil pollution from boats is to be careful during refueling. This includes knowing the capacity of the fuel tank to avoid overflows, shutting off the bilge pump during refueling, and using absorbent pads or fuel collars to catch any drips. It is also important to dispose of waste oils and oily debris properly and promptly. Marinas and fuel docks usually have reception facilities for this purpose.

In addition to preventative measures, it is important to have a plan in place for dealing with oil spills when they do occur. This includes containing and cleaning up spills immediately with absorbent pads or booms to prevent their spread. It is also necessary to notify the relevant authorities, such as the Coast Guard and the state spill response office, as per federal law.

By following these measures, boat owners and operators can play a crucial role in reducing oil pollution in the ocean and protecting marine life.

Prevent oil spills from human error

Human error is an inevitable factor in oil spills. As long as humans are involved in the oil industry, there will always be a risk of human error leading to oil spills. However, there are several measures that can be taken to prevent oil spills from human error:

Proper Training and Protocols

One of the key factors in preventing human error is ensuring that all personnel involved in the oil industry, from those in control rooms to those on the ground, are properly trained and follow established protocols. This includes regular training on spill response and ensuring that monitoring and maintenance are conducted frequently and meticulously.

Addressing Complacency

Complacency is a significant issue that contributes to human error. It is important to foster a culture of vigilance and accountability within the industry. This can be achieved through regular audits, strict adherence to safety standards, and encouraging a reporting system where issues and near-misses are promptly addressed.

Careful Planning and Placement of Infrastructure

The placement of pipelines and other infrastructure is crucial. Often, pipelines are built in environmentally, culturally, or economically sensitive areas, which can exacerbate the impact of a spill. Careful planning and consultation with experts and local communities can help identify less sensitive routes and reduce the potential consequences of a spill.

Reducing Demand and Transitioning to Renewables

Ultimately, decreasing the demand for oil is the most effective way to eliminate the risk of oil spills. Encouraging the use of alternative energy sources, such as renewable and sustainable options, will reduce our reliance on oil. This includes promoting electric vehicles, improving public transportation, and transitioning to renewable energy sources for electricity generation.

Disaster Preparedness and Response

In addition to prevention, it is crucial to have effective disaster preparedness and response plans in place. This includes having the necessary equipment, such as booms, skimmers, and sorbents, readily available and ensuring that response teams are well-trained and able to react quickly to contain and clean up spills before they reach shorelines and cause more extensive damage.

By implementing these measures, we can significantly reduce the risk of oil spills from human error and minimize the environmental, social, and economic impact of such disasters.
