  • Patent number: 8801938
    Abstract: An apparatus, method, and system for recovering oil from a submerged oil source, wherein the system includes a submerged conduit having at least two openings, with a first opening capable of being located in proximity of a leak in order to capture leaking oil, and with a second opening capable of communicating captured leaking oil to another location. A natural gas separator, coupled to the submerged conduit separates the boiling vapor phase natural gas from the captured oil thereby outputting oil with water contaminant. An oil/water separator coupled to the natural gas separator then separates out the contaminant water, resulting in a processed recovered oil product for storage and subsequent refinement. The flow to capture the leak is induced by generating a lower pressure at nozzle in the conduit via power jet, air lift, pumping of fluid out of conduit close to sea level, or other methods.

  • Patent number: 7631444
    Abstract: Material is pneumatically excavated and removed by discharging air under pressure from an excavation nozzle at supersonic speeds in a forward direction for excavating the material, and simultaneously discharging air under pressure from an evacuation nozzle also at supersonic speeds in a rearward direction at an adjacent position rearward of the point of forward discharge for assisting the removal of the excavated material in a rearward direction. The evacuation nozzle is in the form of a continuous annular air stream that is maintained concentric with the excavation nozzle. The nozzles are sized to provide maximum excavation and removal efficiency in co-relation to the PSI and the CFM output capabilities of the selected air source and the nozzles are positioned sufficiently close to each other whereby dynamic flow coupling is established between the nozzles such that material digging and removal performance and efficiency are maximized.

  • Patent number: 6910319
    Abstract: An apparatus and method for cutting plant growth from waterways to promote fluid passage through such waterway. Water under high pressure is forced through a nozzle orifice to cut, chop and/or pulverize the aquatic plant matter. The nozzle is on a spray-head assembly of the apparatus, which is positioned above or in the waterway by the boom of a vehicle such as, for example, a crane or backhoe. As the transport machinery and apparatus are advanced in the waterway, a path is cut through aquatic plant matter by the high pressure water from the nozzle, and, as a result, the waterway may be effectively cleared. In the preferred apparatus and method, wherein the nozzle directs the water vertically into the waterway, a steel plate may be submerged beneath the level of the nozzle and above the soil surface to protect the soil from disruption and erosion.

  • Patent number: 6209965
    Abstract: A method and apparatus for mining of hydrocarbons from a hydrocarbon-containing clathrate such as is found on the ocean floor. The hydrocarbon containing clathrate is disaggregated from sediment by first disrupting clathrate-containing strata using continuous mining means such as a rotary tilling drum, a fluid injector, or a drill. The clathrate-rich portion of sediment thus disrupted from the sea floor strata are carried through the apparatus to regions of relative lower pressure and/or relative higher temperature where the clathrate further dissociates into component hydrocarbons and water. The hydrocarbon is recovered with the assistance of a gas that is injected and buoys the hydrocarbon containing clathrate helping it to rise to regions of lower pressure and temperature where hydrocarbon is released. The sediment separated from the hydrocarbon returns to the ocean floor.

  • Patent number: 6116818
    Abstract: An ocean plow device and accompanying method which incorporate a passive plow blade and a jetter tool working in conjunction with one another to lower drawbar and increase cable deployment speeds. In order to avoid cavitation due to sand dilation, in one embodiment of the plow device, the jetter tool includes nozzles oriented in a downward and backward direction relative to the plow device which creates a flow pattern to turbulently remove surface soil in front of the jetter tool in a rapid manner. The jetter tool is pivotally suspended from a point in front of the passive plow blade, such that the jetter will be free to find its own equilibrium position. That is, the pivotal mounting enables the jetter tool to rotate upward in harder soils and become fully extended in softer soils in order to reach the equilibrium position. The passive plow blade behind the jetter tool provides a constant burial depth for the cable and also provides protection from side loads encountered during deployment.

  • Patent number: 6058630
    Abstract: A suction, or vacuum, is created by the coupling of two sections of tubing of dissimilar size. The larger section of tubing has an open ended reservoir attached to one end thereof. The smaller section of tubing has an end plate attached at a point approximately one third of its length. The longer portion of the smaller section of tubing is inserted into the larger tube until the end plate mated to the reservoir. A fluid medium such as water or air is pumped into the reservoir under high pressure filling the reservoir and encompassing the inner section of tubing. The space between the smaller section of tubing and the larger section of tubing is fluidly coupled to the reservoir. The application of the pressurized fluid medium from the reservoir to the space between the sections of tubing creates a low pressure within the inner tubing resulting in a vacuum or suction being effected at the intake of the inner tubing.
