ABSTRACT:
An oil spill recovery barge utilizes a tank that will pivot about an axis from an upper position to a lower position. The barge has a pair of pontoons, with the tanks located between them. The tank mounts by axles to the pontoons to allow the rotational movement. A flexible buoyant barrier or line extends in a large loop in front of the barge. A puller will gradually pull the line in to constrict the loop to collect the oil spill. A primary separator separates some of the oil from the water and pumps it into a tank. A secondary separator in the tank further separates oil from water and pumps the water from the tank, leaving a greater concentration of oil in the tank. Bridges interconnect the pontoons at the forward and rearward ends. The bridges have flexible joints that allow the pontoons to flex due to wave action.
