  • Oil spill recovery system
    Patent number: 5575586
    Abstract: A system for deploying a cover over an oil spill, to collect the spilled oil, uses a plurality of gas propelled rockets are attached to lines arranged around the periphery of the cover. Outward projection of the rockets spreads the cover, the weight of the expended rockets then pulling the edges of the cover below the water surface to trap the covered oil. Attitude detectors are preferably employed for preventing firing of the rockets when the rocket platform is not generally level.
    Type: Grant
    Filed: March 15, 1995
    Date of Patent: November 19, 1996
    Assignee: Petroleum Recovery Technologies, Inc.

  • Apparatus for spilling retrieval
    Patent number: 3966613
    Abstract: A catamaran with pivotal fore and aft gates defining a well. When moved through a floating liquid spilling with the fore gate open the well collects spilling. The collected spilling may be pumped directly into a tank. Also, the catamaran is equipped with means to deploy a collapsible, floatable retrieval sheet over and into the well to confine the collected spilling, the aft gate being then opened to set the sheet adrift. A peripheral barrier of air bubbles concentrates the oil toward the center of the well.

  • Retrieval means for a floating liquid spilling
    Patent number: 3963617
    Abstract: A flexible sheet having weight means adapted for spreading the sheet over a liquid spilling and causing it to collapse into a floating position, thereby confining and concentrating a quantity of the spilling. The sheet has central flotation means and a vent for release of entrapped air.
