Abstract

It is well known that tackling oil pollution in coastal waters arouses great public

interest. This has prompted ongoing efforts to enhance methods for reducing oil contamination.

Conventional oil barriers are frequently used as part of the chosen pollution reduction technique

to confine floating oil. In the event of an oil spill into the sea, a rapid and effective response to

pollution is of vital importance for environmental safety. The effectiveness of the conventional

barriers used today in the response to oil pollution at sea is very low. Air bubble barrier has

been developed to eliminate the inefficiency of conventional oil containment barriers and used

as a new type of oil containment barrier. Air bubble barriers are created by the release of air

bubbles underwater; air bubbles rise to the surface, forming a bubble cloud. This plume creates

an upward flow by dragging water with it. A surface current is created when the water's upward

flow changes direction as it approaches the surface. As a result, convection-dominated oil spills

can be avoided, and spilled oil is anticipated to be contained in a specific area. In this study,

studies on air bubble barriers have been compiled based on features such as purpose/main topic,

analysis type, dimension of numerical analysis, size of the experimental setup and numerical

model, aperture size, aperture separation interval, pipes submerged depth and pipe arrangement.

It has been found that the air bubble barrier is mainly investigated for oil spill situations and

wave dissipating performance. Additionally, we might infer that an experimental setup is

required to assess how well the air bubble barrier controls the oil pollution spread. However, it

may be said that only numerical simulation is enough to determine how well the wave

dissipating performance of the air bubble barrier.
