How to choose an oil containment boom

Three factors must be borne in mind when choosing a containment boom: buoyancy, roll response and heave response.

How to choose an oil containment boom for use in different environments

In general there are two types of containment boom (see fig.1):

  • Flat floatation containment booms.
  • Cylindrical floatation containment booms (floats may be foam-filled or inflatable).

Contaiment boom characteristics

Three factors must be borne in mind when choosing a containment boom: buoyancy, roll response and heave response.

Buoyancy

Is important in order to maintain sufficient freeboard in rough seas. It depends directly on boom volume (see fig. 2).

Roll response

Is the rotation of the boom from rest due to wave, wind or current forces.
A high roll angle reduces effective freeboard and draft, thereby decreasing the boom’s containment properties (fig. 3).

Heave response

Is the ability of the boom to react to the vertical motion of the water surface and is proportional to the lateral area of the boom at the waterline, termed the water plane area.
A boom with poor heave response may be submerged by a wave and a boom with good heave response will float above the wave (see figs. 4 , 5 and 6).

Behaviour of different contaiment boom types

Flat floatation booms have relatively low buoyancy due to their low volume, have poor roll response to wave, wind or current forces and poor heave response due to their low water plane area. However their flat design means they are compact and can be stowed on winders, making them easy to use. They are suitable for use in protected waters such as harbours and lakes.

Cylindrical floatation booms have high buoyancy and maintain freeboard height in rough seas. Roll is kept to a minimum because the skirt moves independently from the floats and is weighed down by the bottom chain. The large water plane area gives good heave response and good wave-following characteristics.

Foam-filled floatation versions can be immediately deployed but are bulky to store, while inflatable floatation versions are either self-inflatable or require compressors for inflation and deployment. However, inflatable versions have the advantage of being stowable on winders, thereby taking up little storage space.
