Definitions

  • This invention relates to a novel apparatus and a method for recovering oil spills in marine environments and removing uncontrolled plant growth.
  • Examples of large scale environmental oil spills include the Torrey Canyon oil spill in the English Channel in the 1970's, which destroyed wildlife in huge areas, leaving fouled beaches of France and England for over ten years, and creating tremendous difficulties for fishermen and people living in the damaged area. More recently the Exxon Valdez stranded on a reef in the Gulf of Alaska spilling tens of millions of gallons of crude oil into the ocean with catastrophic loss of life, such as sea birds, seals, salmon and shellfish. After much effort, only about 10,000 barrels of crude oil were recovered. The Prestige oil vessel leaked large amounts of oil off the Galician coast in November 2002. The Prestige was carrying two times more oil than the Exxon Valdes. The rescue effort after that accident included attaching valves to the wreckage and capturing the floating oil over the wreckage, as well as a huge effort of the fishermen in the area capturing oil from the shore. The damage of this catastrophe is yet to be estimated.
  • suction devices In order to efficiently recover oil spill, extending over large surface areas of water, suction devices have been employed in the past. The use of devices of such type aim at drawing the oil spill off the water surface, typically through pipes and suction devices. The problem with these methods, in particular regarding larger oil spills is that the percentage of oil spill recovered as compared to water is relatively low and therefore the method is time consuming. As a consequence an oil spill usually spread faster than it is cleaned up. A separation device is then mounted on board a vessel or onshore and in some cases the suction equipment must be towed behind a vessel or beside. In order to be able to recover oil, high capacity pumps and compressors are required as well for separating the oil from the water. Methods and devices have been suggested in the prior art to deal with oil spill accidents.
