Floatable Matter Containment Patents (Class 405/60)
  • Patent number: 5406019
    Abstract: The present invention is used in response to petroleum related spills in the environment. The hydrocarbon materials can be removed from any substrate, particularly ice or beach sand, by impinging in two separate fluid streams, a formable surfactant/emulsifying solution with a latent foaming agent and a foam inducing agent through specially designed variable pressure guns. Once treated, the petroleum-related liquids are lifted above the substrate in a foam matrix formed while the solution is in contact with the spilled contaminants, and captured via standard industrial vacuum technology for later disposal.

  • Patent number: 5271691
    Abstract: An oil cleanup method and apparatus uses processed kenaf that is processed using a cutter to preliminarily cut the kenaf stalks into short pieces or billets. These billets are threshed to separate fiber and core portions of the kenaf billets. The billet size thus defines the fiber length and thus fiber product texture. Separators grade the particulate core after threshing. The core particles are added to a container such as a bale or boom that will float on the surface of an oil slick in an aquatic or marine environment. The bales can also be added to dry spills to absorb the oil. The particulate kenaf core can be added to a treatment vessel, such as a vertical column and with inlet and outlet portions. Wastewater with an oil portion can be added to the treatment vessel and the core particles removes oil from the wastewater stream. Sludge solidification can be accomplished with the kenaf particles.

  • Patent number: 4960347
    Abstract: This invention teaches that when a section of a tanker is damaged, the ship being far from shore-based help, it is imperative that the liquid cargo be transferred from the ruptured tank to an undamaged tank on the ship as quickly as possible. By doing so, the contents of the damaged tank are less likely to escape in a sufficiently voluminous quantity to seriously befoul the environment. To that end, a normally-empty emergency holding tank is provided on the ship with means to provide for emergency transfer of the liquid cargo from the damaged section into the emergency holding tank. At the same time, the ruptured tank is enshrouded by a flexible barrier curtain to entrap whatever liquid cargo that may have leaked from the damaged tank.

  • Patent number: 4523879
    Abstract: A method is provided for constructing spray ice barriers to protect offshore structures in a frigid body of water from mobile ice, waves and currents. Water is withdrawn from the body of water and is sprayed through ambient air which is below the freezing temperature of the water so that a substantial amount of the water freezes as it passes through the air. The sprayed water is directed to build up a mass of ice having a size and shape adapted to protect the offshore structure. Spray ice barriers can also be constructed for the containment of pollutant spills.

  • Patent number: 4447247
    Abstract: A method and an apparatus for collecting oil and gas flowing uncontrolled into a body of water beneath the water surface, especially in a blow-out from a point at the sea bed. The oil and gas discharged from the blow-out location is caught and ascends towards the surface within a tubular shell body and the gas is collected in a floating gas bell provided at the upper end portion of the shell body and forming a gas or liquid trap against the surrounding water in that it has an outer wall projecting downwards and surrounding an upper portion of the shell body. The gas is thus automatically placed under a controllable positive pressure in that the displacement of the gas bell in the medium within the shell body can be varied by ballast means. The apparatus includes an upper member (2) constituting a gas-collecting bell, and a lower member (1) constituted by the shell body.

  • Patent number: 4416565
    Abstract: Method by collection and separation of oil, gas and water from an offshore oil/gas well (2) and a column (1) for usage by the same.The column (1) comprising a vertically arranged tube (3) with a lower end (8) resting on the sea bed (14) and an upper closed end (9) from which gas may be discharged by gas outlet means (6). Oil-gas mixture flowing out of a well head (22) in operation of the column (1) will be retarded by an oil column (10) in the tube (3), thereby releasing gas which is collected in the upper portion (11) of the column. Motion of the oil at the surface of the oil column (10) will be very small, oil thereby flowing over an overflow rim (15) into an overflow channel (26), from where oil is transferred to the sea surface by oil outlet means (7).The motion of the mixture may be additionally dampened by horizontal webs.The column (1) may be operated at sea depths more than 300 meters and at shallow water where the column may be constructed as part of a platform.

  • Patent number: 4405258
    Abstract: An improved method for storing a lighter-than-water fluid, e.g., oil, produced from the blowout of an offshore subsea well is provided herein. The method includes the steps of deploying a containment dome in shallow water near the location of the seabed where the containment dome is to be located. The containment dome as an upper expanded dome-like fluid impervious membrane, a fluid impervious hollow peripheral ring attached to the periphery of the membrane to provide a depending bag-like container, and discrete water drainage means within the bag-like container for connection to pump conduit means therefrom. Wet sand from the seabed is then pumped into the bag-like container, and water is then drained from the wet sand through the water drainage means so as to provide a body of drained sand disposed within the bag-like container and providing a hollow peripheral ring as a hollow peripheral torus acting as a self-supporting structure and as an anchor for the dome-like structural unit.

  • Patent number: 4382716
    Abstract: A blowout recovery vehicle for recovering the discharge from underwater wells comprises a large inverted entrapment shell positionable over a well and having overly extending tubes connected by hose means to surface separation and storage equipment. Floatation tanks are connected to the surface by air lines which are actuated to adjust the buoyancy of the device to raise or lower it so that it can be lowered over a well to trap the discharge from the well. In use, the assembled device can be towed by a tug into position or can be assembled in the water at the site and lowered over the well without the necessity of the tug coming into the effluent discharge area above the well. Alternatively, an anchor can be placed in the seabed directly upstream of the well at some distance from the well.
