CONTAINMENT

Containment is a pollution response technique which can be used both in the open sea and in port and coastal areas. It involves the use of floating booms and aims to:

  • Reduce the spreading of slicks of pollutant
  • Thicken slicks and control their drift
  • Concentrate the pollutant to optimise its recovery by pumping or using sorbents
  • Protect a given area.

Containment therefore optimises pollutant recovery operations at sea, generally carried using skimmers.

A pollutant can be contained at the surface using floating booms. Several types of booms exist:

  • Inflatable booms, mainly designed for the open sea
This type of boom comprises an inflatable buoyancy chamber and a “skirt” on the lower part and is mainly designed to be used in the open sea for the dynamic containment of a slick.

These booms are stored on land wound on reels.
  • Foam-filled booms, designed for sheltered and port areas
These booms, made up of foam blocks enclosed in watertight pockets, are generally used to contain a slick of pollutant in a coastal or port area, or to protect a sensitive part of the shoreline from the arrival of pollutant from the sea.

These booms are stored on land in containers.

  • Permanent booms
These booms are used for the permanent protection of a sensitive area. They can be left in place for several months.

  • Fireproof and hazmat booms
Booms made entirely of stainless steel can be used to contain oil or chemicals. They are fireproof up to a temperature of 1250°C without compromising their mechanical characteristics and their watertight seal.
