What type of booming consists of three vessels and a skimmer to maintain shape?

The type of booming that consists of three vessels and a skimmer to maintain its shape is referred to as V booming. This configuration is specifically designed to effectively contain and collect oil spills or other hazardous materials in a more controlled manner.

In V booming, the two outer vessels create a V-shaped barrier that serves to direct the contaminant towards the skimmer, which is positioned at the apex of the V. This arrangement helps to maximize the collection efficiency as it encourages the fluid to flow inward, making it easier for the skimmer to collect and remove the substance from the water.

Other types of booming, such as U booming or J booming, have distinct configurations and methods of operation that do not specifically use three vessels in the same manner as V booming, nor do they focus on the same shape-maintaining structure combined with a skimmer. Containment booming is more general and does not imply the specific arrangement needed to effectively manage the situation described.
