In situ burning, as it relates to oil spills, is the controlled burning of oil on water at or near the spill site.
In-situ burning is an oil spill response tactic which involves the controlled ignition and burning of oil on the surface of the water. It is generally conducted at or nearby the spill source, but could feasibly be conducted anyplace that enough spilled product is captured in boom. Oil must first be contained with boom or by barriers such as ice or remote shorelines and the slick thick enough (2-3 mm) to insulate itself from the underlying water.
Most oils spread rapidly on water and the slick quickly becomes too thin for burning to be feasible. Fire-resistant booms can be used to concentrate the oil into.
These methods include containment (booms and skimmers), sorbents, in-situ burning, dispersants, conventional bioremediation, using high pressure hoses, vacuum trucks, and other machines for mechanical oil cleanup. Floating dummies/balloons, water cannons, buoys and horns can be used in attempt to keep wildlife away from a spill site.
Jun 18, 2018 the practice of burning oil spills has been a fast and relatively safe way to reduce the impact on water quality and marine life.
Applied response technologies (art) generally fall into two main categories: use of an oil spill cleanup agent (such as dispersants, surface washing agents, oil gelling or solidifying agents, oil herding agents, de-emulsifiers, bioremediants, and sorbents, or; use of oil burning (in-situ burning, or isb), either on water or on land.
Oct 15, 2020 nist measurements and predictions have played a major role in establishing in situ burning as a primary oil spill response method.
In certain cases – usually in remote areas – it is possible to burn off spilled oil in situ (latin for in place). Burning can eliminate large volumes of oil quickly and effectively; however, it also burns off plant life and leaves residue that can adversely affect the ecosystem. Special fire-resistant booms must be used to contain open-water burns, as burning oil may spread rapidly in water.
Nist measurements and predictions have played a major role in establishing in situ burning as a primary oil spill response method.
Burning oil on water is not intuitive and thus many people did not pursue this course of action. Recently, the successful use of in-situ burning on the deep water horizon spill in the gulf of mexico drew attention to the technique and left a very positive image of burning. In-situ burning has been used to deal with land spills for many years.
In-situ burning can remove approximately 100 gallons/day/square foot of surface area under ideal conditions. By removing oil from the water surface, we are protecting birds, marine mammals, turtles, and the sensitive florida coast from the effects of the oil spill.
The full potential for in situ burning as a controlled oil spill response technique is a subject of growing interest throughout the world. Information now available from burning oil during accidental fires, war-related fires in kuwait, spillage from the exxon valdez and controlled test burns, permits an objective and comprehensive assessment of both the positive and negative aspects of in situ burning.
In situ burning involves the controlled burning of oil that has spilled from a vessel or a facility, at the location of the spill. When conducted properly, in situ burning significantly reduces the amount of oil on the water and minimizes the adverse effect of the oil on the environment.
Abstract: the full potential for in situ burning as a controlled oil spill response technique is a subject of growing interest throughout the world.

They may authorize burning when: mechanical containment and recovery by themselves are incapable of controlling the oil spill, burning is feasible, and the burn will lie a safe distance from populated areas.
In-situ burning is one of the few practical options for removing oil spilled in ice-covered waters. In many instances in-situ burning, combined with surveillance and monitoring, may be the only response possible. As with all countermeasures in any environment, the suitability of burning a particular spill depends on the characteristics of the spilled oil and how the oil behaves in the particular ice conditions.
Apr 2, 2013 the burning of oil in place (in situ) on water is a viable means of mitigating the impact of marine oil spills.

Aug 9, 2016 in situ burning, or isb, is a standard tactic for dealing with large-scale oil spills in water.
This guide is intended to assist oil spill responders who are considering or executing controlled in-situ burning of an inland spill. In-situ burning (isb) is the combustion of hydrocarbon vapors from spilled oil which are converted predominantly to carbon dioxide and water and released to the atmosphere.
• in-situ burning involves controlled burning of oil that has spilled from a vessel or a facility, including pipelines. • for an in-situ burn on water to ignite and sustain, the spilled oil must be approximately 1/10 of an inch or 2—3 millimeters in thicknessñso containment in some form is necessary to limit spreading.
Sep 1, 2013 in-situ burning of spilled oil on the water's surface involves a controlled burn of floating oil that is contained to the appropriate thickness.
Feb 4, 2005 in-situ burning of spilled oil, which receives considerable attention in marine conditions, could be an effective way to cleanup wetland oil spills.
The risks posed by in situ burning must be considered among all the risks posed to human health and the environment by oil spills and the countermeasures available to the on-scene coordinator. These trade-offs should be discussed and resolved by the rrt in the planning process.
Feb 4, 1999 in-situ burning of spilled oil has some distinct advantages as a response option.
In-situ burning is the oldest technique applied to oil spills and is also one of the few techniques that have not been explored in scientific depth until recently.
In-situ burning in-situ burning is the term given to the process of burning floating oil at sea, at or close to the site of a spill. In order to undertake burning, the oil must be concentrated and an ignition source applied. Burning oil at seas has, in ideal conditions, the potential to remove relatively large amounts of oil from the sea surface.
This guide contains information about the in-situ burning of oil spills and the scientific aspects of the burning process and its effects. It also presents practical information on the procedures and equipment required for isb operations. Isb is a non-mechanical response option as, for example, is the application of oil spill dispersants.
One important exception is very light, refined oil products, f or which burning poses a safety risk. The ability to use in situ burning as a response option decreases with time and oil weathering. In situ burning might be suitable within 72 hours after a spill.
Oct 16, 2020 because large spills are rare events, oil spill response techniques are often evaluated with laboratory and meso-scale experiments.
In situ burn emissions observed from an overflight during the 2010 deepwater horizon/bp oil spill.

May 23, 2014 one common method for cleaning up oil spills is called in situ burning, in which technicians set the fuel slick on fire to vaporize its components.
In-situ burning of spilled oil, which receives considerable attention in marine conditions, could be an effective way to cleanup wetland oil spills. An experimental in-situ burn was conducted to study the effects of oil type, marsh type, and water depth on oil chemistry and oil removal efficiency from the water surface and sediment.
While in-situ burning of oil spills has been tried over the past 30 years, it has only recently been accepted as an oil spill cleanup option in some countries.
In situ burning, intentional burning of discharged oil on the water surface, is a promising response method to oil spill accidents in the arctic.
In-situ burning (isb), along with the use of chemical herders (to thicken the slick of spilled oil) has emerged as a potentially viable oil-spill response t with increased oil exploration and marine activity in the warming arctic, there is an increased risk of future oil spills in the arctic region.
In-situ burning is a fancy name for burning the oil where it was spilled. The oil can be contained by fire-resistant booms at the spill site, then set on fire and burned away. This works really well with light oils, since they give off more vapors that burn. Under certain circumstances, in-situ oil burns can be a very effective means of spill cleanup.
In-situ burning is recognized as a viable alternative for cleaning up oil spills on land and water.
If an oil spill were to occur under icy conditions in the arctic, in-situ burning (isb) may be the only option for efficient clean up, because the remoteness and harsh climactic conditions is likely to make it impossible for heavy machinery to be deployed immediately after a spill to facilitate either mechanical recovery or the use of dispersants, which are the two other primary response methods for off-shore oil spill cleanup.
In situ burning is a method by which oil is burned at a spill site under controlled conditions, and this method is subject to increased interest due to its applicability in the arctic.
