ABSTRACT:
A barrier for the containment and recovery of oil spilt on water comprises a first buoyant air chamber 1, a ballast water chamber 2, an oil and water discharge tube 3 and a second buoyant air chamber 6. The first air chamber 1 has a plurality of sections of reduced diameter 7, which together with the ballast water chamber 2 define a series of weirs for oil and water to pass into a gallery formed by the ballast water chamber 2, the oil and water discharge tube 3 and the second air chamber 6. Pumps 4 may be provided in the oil and water discharge tube 3 to remove oil from the gallery. The second air chamber 6 provides buoyancy to maintain the optimum configuration of the weirs.
