What is one type of boom failure associated with oil spills?

Entrainment refers to the process during which oil is pulled underneath the boom due to wave action, currents, or turbulence in the water. This failure occurs when the boom is unable to contain the oil effectively because the forces acting on the oil exceed the boom's ability to hold it back. When oil is entrained, it can disperse into the surrounding water, making recovery efforts more difficult and expanding the area affected by the spill. Understanding entrainment is crucial for responders, as it highlights the limitations of booms in certain environmental conditions and emphasizes the need for complementary recovery techniques.
