A method of containing a spill in an aqueous environment comprises the following steps: placing a boom being inherently buoyant under the surface level of the aqueous environment in the vicinity of a site of potential spillage; holding the boom under the surface level against its buoyancy by employing one of a tether, a ballast or a propeller; and raising the boom from under the surface level to a containment level by detaching and/or adjusting the tether, by separating the ballast or by changing the infuence of the propeller. The boom forms, when raised, at least a partial boundary around the spill for containing the spill and comprises a polymeric pipe (6) providing the inherent buoyancy of the boom. |
