Definitions

  • the invention relates to a protective device to fluids, whether gaseous or liquid, the uncontrolled escape into a body of water, eg. B. from a fault in the river bottom or from the defective riser of a borehole to prevent.
  • BOP Blow-Out Preventers
  • the FR 2 004 935 discloses a protective device for catching a fluid escaping into a body of water.
  • the invention is based on the object of collecting a flowing into a body of water or floating in a body of fluid having a density which is equal to or less than the density of water, to separate from water and supply a further processing or disposal.
  • fluids are, for example, oil or gas escaping or leaking from a wellbore.
  • the protective device according to the invention for collecting a fluid escaping into a body of water comprises a fluid-impermeable, optionally dome-shaped membrane made of a suitable material, such as foil or fabric.
  • the membrane may for example be made of a plastic film, which in turn can be vapor-deposited to protect against destruction by the fluid, for example with a metal layer.
  • the Membrane eg consist of a metal mesh, which is coated for sealing with a plastic.
  • Suitable is a flexible material that is resistant to the fluid, d. H. its physical properties do not change upon contact with the fluid. It may also be textile material e.g. Carbon fiber or a metal braid are used, which is coated for sealing with a suitable substance, optionally with a plastic, a polymer based on plant or a biopolymer. Furthermore, certain plastic films or films of a polymer based on plants and possibly biopolymers are suitable.
  • the shape of the membrane and its size are preferably by mechanisms such.
  • An object such as the membrane, is generally referred to as domed when the surfaces of the object each form a surface of a portion of a convex body.
  • a section of a body is to be understood as a partial body whose points are all located on the same side of an unlimited surface, for example a plane.
  • a dome is a section of a body of revolution, which has emerged from a conic.
  • a spherical cap is a section of a sphere.
  • the membrane is in the form of a dome or portion of a convex polyhedron.
  • Floating bodies are preferably attached to the membrane for positioning and stabilizing the membrane. These are individually navigable, ie individually, in all spatial directions. The positioning of the float can be done automatically, ie programmatically or remotely.
  • Remote controlled watercraft ROV, "Remotely Operated Vehicle ”
  • AUV Autonomous Underwater Vehicle
  • protective devices according to the invention can be realized in almost any size. In particular, very large-sized membranes are made possible.
  • the membrane can be closed with a correspondingly shaped or malleable lip.
  • weights ie. H. Elements whose density exceeds the density of water may be appropriate.
  • the membrane floats freely at a predetermined depth, wherein a positioning of the membrane takes place exclusively by the float.
  • the membrane is preferably embedded in the water in the folded state. If floating fluids whose density is equal to the density of water are to be collected in the water, the floats preferably deploy the membrane above the suspended fluids. After that, the membrane is lowered. This has the consequence that the floating fluids are trapped by the membrane and thus collected.
  • the floats When the fluid enters the water from a source, such as a leaked well, and the density of the fluid is less than the density of water, the floats preferably position the membrane in a folded state over the source. Ascending fluid now hits the membrane and enters the membrane. As a result of the buoyancy of the fluid, the membrane unfolds as a result.
  • the density of the membrane is preferably equal to or less than the density of water. This may be due to production or by appropriate specific weight or, if appropriate, by appropriate gas or solid state inclusions.
  • the wall may be depth-related in terms of the specific weight of different manufactured parts.
  • the membrane consists of at least two segments, the densities of the at least two segments differing.
  • the density of a first of the at least two segments is less than the density of a second of the at least two segments, if the first of the at least two segments or the center of gravity of its buoyancy with respect to the water surface are arranged higher, d. H. is closer to the water surface is, as the second of the at least two segments or the center of gravity of its buoyancy.
  • higher segmented segments provide greater lift than deeper segmented segments. This simplifies the positioning of the membrane by the weights and / or floats.
  • One or more outlet hoses are attached to the membrane.
  • the fluid is discharged in the direction of the water surface. If the density of the fluid is lower than the density of water, no pump is required for this purpose.
  • a valve at the interface between the outlet tube and the membrane prevents uncontrolled outflow of the fluid.
  • the valve can be remotely controlled. Alternatively, a controlled by level sensors, automatic actuation of the valve is possible.
  • the outlet tube should be made of a flexible material whose density is preferably equal to or less than the density of water. This can damage the membrane through the outlet hose. Furthermore, the positioning and stabilization of the outlet tube is simplified.
  • Floats of the type described above are attached to the outlet hose for positioning and stabilizing the outlet hose.
  • the outlet tube therefore consists of a plurality of coupled tube segments.
  • the outlet hose If the outlet hose is damaged, there is a risk that the discharged fluid will flow from the damaged area into the water. This is prevented in a preferred embodiment of the invention by at least one check valve which is arranged in the outlet hose so that it can retain fluid flowing from the membrane towards the water surface. If the outlet hose is damaged, the flow velocity increases or the flow direction of the fluid that flows out of the membrane through the outlet hose changes. As soon as the flow velocity has exceeded a threshold value or a reversal of the flow direction takes place, the check valve blocks. If the flow velocity is below the threshold value, however, the check valve is continuous.
  • a conventional mechanical check valve can be installed.
  • a spring-biased check valve can be installed, which can withstand the flow of the fluid only up to a certain flow rate. The spring preload can hold the valve open only up to this flow rate, Thereafter, the valve is closed by the flow or the associated pressure against the spring preload.
  • a preferred embodiment of the invention of the protection device therefore has openings, so-called fish or boat store on through which the fish and / or submarines can escape from the membrane into the water.
  • the fish or boot store can be designed as closable, inclined in the direction of the body of water bottom recesses in the membrane. Due to the inclination of the fish or boat store, fluid that flows into the membrane is conducted past the fish or boat gates. As a result, as long as the level of the fluid within the membrane is above the fish or boat store, as a result, hardly any fluid can escape through the fish or boat store into the water. If so much fluid accumulates inside the membrane that the level of the fluid sinks to the fish or boat gate, the fish or boat gates are closed.
  • the fish or boat gates are alternatively designed as a trunk.
  • the first of two openings of the spout is connected to the membrane along the edge of a recess in the membrane.
  • the proboscis is of the same material as the membrane. Ring-shaped reinforcements along the trunk prevent the trunk from collapsing.
  • Floats of the type described above are attached to the trunk for positioning and stabilizing the trunk. So that no fluid can escape from the trunk, the floating bodies align the trunk so that the second, pointing in the direction of the water of the two openings of the trunk is below the level of fluid within the membrane.
  • the fish or boat gates can also serve to compensate for currents that act on the membrane.
  • a second end of the outlet tube is attached in a preferred embodiment of the invention to a surface station for buffering and pumping off the fluid.
  • the density of the outlet tube should be equal to or less than the density of water.
  • the surface station is not fixed, for example by anchoring at the bottom of the water. Instead, the surface station floats freely on the water and can thus follow the movements of the membrane, which is also free-floating.
  • the surface station has one or more controllable or navigable drive units for positioning and stabilization.
  • the surface station can be kept together with a corresponding tank by appropriate floats and Tarier Roaden at a predetermined depth under water.
  • the fluid emerging from the outlet tube in the surface station is preferably collected in a dome-shaped tank associated with the surface station, such as in the manner of cantilevered halls or by means of such devices.
  • the lower opening of the tank is located on or below the water surface. Fluid entering the tank thus floats within the tank on the water surface. Aqueous ingredients that may be are contained in the fluid are separated in this way without the use of specific aids from the fluid and returned to the water.
  • This barrier layer is optionally formed by a liquid filled in the tank whose density is higher than the density of the fluid and lower than the density of water. It can also be designed as a membrane of suitable material - made of film or textile material.
  • the tank is preferably subdivided into several sections.
  • FIG. 1 a protective device 10 is shown whose membrane 12 has been unfolded over a fault 14 in the body of water 15, from which a fluid emerges, or via a defective riser 16, from which a fluid emerges.
  • the individually navigable floating bodies 17 position the membrane 12 so that it is above the fault 14 or above the defective riser 16. If the density of the fluid is less than the density of water, the fluid rises and collects in the membrane 12.
  • reinforcing struts 18 In order to make the membrane 12 resistant to the buoyancy forces of the fluid and to ocean currents, it is provided with reinforcing struts 18.
  • the reinforcing struts 18 may for example also consist of glass fiber reinforced plastic or of a fiber composite material.
  • the membrane 12 can also be stabilized by pressure lines.
  • An adapter block 100 which is mounted at the highest point of the membrane 12, couples the membrane 12 to the outlet tube 102.
  • the adapter block 100 has valves and control mechanisms as well as the necessary measurement and regulatory system. Floats (not shown) position the adapter block 100. Cameras and sensors control the condition and function of the adapter block 100.
  • individually navigable floats 17 hold the outlet hose 102 in position.
  • a valve in the adapter block 100 releases the fluid collected within the diaphragm 12. As a result, this flows through the outlet hose 102 in the surface station 104. Here, the fluid accumulates in the dome-shaped tank 106.
  • This can be made of suitable materials, of film or textile material, but also for example of solids such as steel.
  • At the surface station 104 are all necessary technical connectors 105 for connection to tankers, for environmental disposal or for direct further processing of the fluid.
  • the surface station 104 floats freely on the water surface 107 so that water can enter the tank 106 from below. On the water, inside the tank 106, the fluid floats. Above this, also in the tank 106, is air.
  • the buoyancy of the surface station 104 can be balanced.
  • the surface station 104 has one or more floats 108.
  • a circumferential anchor lip 110 encloses the opening of the tank 106.
  • the anchor lip 110 prevents lateral outflow of the fluid.
  • membrane 12 has a fish gate 20 - a closable, in the direction of the body of water 15 inclined opening - on.
  • the inclination of the fish gate 20 prevents the fluid 22 flowing out of the fault 14 in the body of water 15 from escaping into the water, as long as the filling level of the membrane is still sufficiently small.
  • fish 24 can leave the membrane 12 through the fish gate 20.
