SYSTEMS FOR AMELIORATING OIL SPILLS IN MARINE AND INLAND WATERS

摘要

A plurality of water and oil porous sacks (10) are partially filled with a number of generally toroidal bodies of a polymer material that entraps oil, and includes mesh fragments scattered throughout the bodies. Each sack is sewn with a perimeter stiffening ring (110), to retain a flat profile, and has a netting that closes to help inhibit outflow of the oil when the sack is retrieved. When deployed from a ship, or by air onto an open-water surface (50), the sacks spread into pancake shape and the polymer matter forms a single layer that retains the oil. The inventive sacks will float indefinitely without releasing the oil or allowing it to emulsify, so the oil can remain in place until collection efforts are feasible. The sacks can be burned in situ, or standard fishing boats or specialized collection boats can be used to retrieve the sacks, and the collected material can be burned to capture the energy content of the oil or processed to separate the oil from the polymer. The inventive sacks can be used in conjunction with other, known containment or retrieval equipment, such as booms or skimmers. The system is specially designed for rapid deployment and efficiency in rough water.
