<p>The invention relates to an oil boom of the kind which includes an elongated hose-like buoyant body and internal boom-distending elements in the form of inflatable annular hoses attached to the buoyant body. The annular hoses extend generally around the inner circumference of the buoyant body and when inflated to their state of use distend the body into a hose-like shape. The annular hoses are mutually connected pressure-wise through the medium of other elongated hose elements. The oil boom is characterized in that at least when transported to its intended deployment site, the boom is in a rolled-up state or in some other packaged state which forms a boom pack that is held together by suitable means; and in that the annular hoses and their connecting hose elements are filled with air or some other appropriate gas at a pressure which when the boom is deployed and the boom-pack securing means have been loosened or released will cause the boom pack to expand explosively to achieve its effective state of use and therewith essentially its full length. The pressure in the boom pack is preferably 10-20% higher than the predetermined pressure of the boom in its state of use.</p> |
