Definitions

  • the invention relates to a noise-reducing device for underwater pile driving, comprising at least one pipe that can be fixed to the seabed and has a plurality of boreholes, and at least one compressor with which compressed air can be introduced into the pipe so that it can exit through the boreholes.
  • the invention further relates to a method for reducing the transmission of sound in a liquid, comprising the following steps: deploying a pipe on the seabed that encircles the sound source and is provided with boreholes, and introducing compressed air into the pipe so that it exits through the boreholes.
  • Such devices and methods can be used for noise reduction when installing cylindrical piles into the seabed.
  • These piles can be used to anchor monopile, tripod, triplepile, or jacket structures, upon which structures such as wind measurement masts, wind turbines, drilling platforms, or substations can be founded in offshore areas.
  • the aforementioned foundation structures can be largely prefabricated on land, allowing for quick and easy installation on site, often under challenging weather conditions.
  • a disadvantage is the need for heavy pile-driving equipment, which generates a high noise level, for example, exceeding 130 dB. Such noise levels can be harmful to marine life.
  • a hose reel for an air hose is known that makes it possible to quickly wind and unwind the air hose of a machine tool under pressure at various directional angles from the mounting position.
  • the JP 2000-302199 A This reveals a hose reel for a pneumatic tool, which allows work to begin immediately after the hose reel has been moved to the work site and connected to an air supply. Furthermore, the hose is quickly replaceable thanks to a quick-connect fitting on the outer surface of the reel.
  • the WO 91/07546 A1 shows a floating oil boom which has an air-absorbing buoyancy element and a curtain suspended from the buoyancy element.
  • the invention is therefore based on the objective of providing a device and a method for underwater pile driving which combines good sound insulation with low equipment costs, so that the sound insulation measures can be carried out quickly and easily.
  • the pipe which surrounds the pile driving site in an approximately ring-like manner, for noise reduction during pile driving operations. Due to the density inhomogeneity between the rising air bubbles and the surrounding seawater, as well as the compressibility of the air bubbles, the energy of the sound waves can be at least partially dissipated, so that a lower sound intensity prevails outside the bubble curtain.
  • the pipe can be laid out so that it completely encircles the pile driving site. If a reduction is only required in certain directions, the pipe can, of course, be laid out only in those directions, or the ring around the pile driving site can be left open.
  • the compressed air exiting the pipeline is supplied by at least one compressor, which is usually mounted on the water's surface on a ship or jack-up barge.
  • the compressed ambient air is then fed into the pipeline via a supply hose and exits through multiple boreholes drilled along the pipeline's length.
  • the conduit it is proposed to insert a weight inside the conduit.
  • This increases the overall weight of the conduit sufficiently to allow it to remain on the seabed without additional anchoring or external weights. Since the weight is located inside the conduit, its external shape remains unchanged, allowing it to continue to be easily deployed and/or removed without external weights hindering the process.
  • Anchoring by divers is also possible, but usually unnecessary. At the very least, the number of anchors can be reduced or the distance between anchor points increased, as the pipeline remains on the seabed due to its own weight.
  • the weighting element may contain a metal or an alloy. In other embodiments, the weighting element may contain or consist of a mineral material, such as concrete.
  • the weighting element(s) may be incorporated directly into the pipe during production, for example, by extrusion. Weighting elements may also be glued, screwed, or riveted into the pipe at certain intervals. In one embodiment of the invention, several weighting elements may be connected to one another by a wire rope or chain, which prevents slippage along the longitudinal extent of the pipe. In another embodiment of the invention, at least one sufficiently dimensioned chain with a plurality of chain links may be used as the sole weighting element.
  • Such a weight can simply be inserted into the cable. Due to the flexibility of the chain links, the weight does not, or only minimally, impede the winding and unwinding of the cable.
  • the conduit can have at least one longitudinal section comprising a hose with a wall, wherein the wall contains at least one layer of wire mesh.
  • the wall contains at least one layer of wire mesh.
  • several layers of wire mesh can be present in the wall.
  • the number of layers of wire mesh can be between 1 and 8, between 2 and 7, or between 3 and 5.
  • the wire mesh in the wall of the hose increases its tensile strength, thus preventing mechanical damage or unacceptable changes in cross-section or length when the hose is unwound.
  • the wire mesh can limit the elasticity of the hose, so that it retains its desired cross-section even under high overpressure. This allows the device to be operated with greater reliability and to be inserted and removed with particular safety.
  • the wire mesh and/or the chain, or at least one weighting element may contain or consist of stainless steel.
  • stainless steel is understood to mean an alloy steel that is corrosion-resistant or at least corrosion-inhibiting.
  • steels with material numbers 1.4401, 1.4571, or 1.4462 may be used. The use of these stainless steels extends the service life of the proposed device if seawater comes into contact with the weighting element and/or the wire mesh through the air outlet openings or damage to the wall.
  • the noise-shielding device further comprises at least one winding device with at least one drum onto which the cable can be wound.
  • the drum can have a drive, for example, an electric or hydraulic drive.
  • the drum can be configured to accommodate more than approximately 900 m, more than approximately 1000 m, or more than approximately 1100 m of the cable.
  • the cable may be sufficient to wind the cable onto the drum while the ship is essentially drifting without propulsion or with minimal engine power.
  • This guides the ship along the cable as if it were an anchor chain, and it follows the cable's path backwards while the cable is wound onto the drum.
  • a cable with increased tensile strength such as the proposed embodiment with at least one wire mesh in its wall, proves advantageous.
  • the ballast body can also serve to absorb tensile forces if it contains or consists of a chain or wire rope.
  • conduits can be deployed simultaneously, each encircling the noise source in a ring-like fashion. This creates several bubble curtains arranged approximately concentrically. Since a single bubble curtain from a single conduit reduces the noise by approximately 12 dB to approximately 20 dB, a correspondingly greater reduction can be achieved by using multiple bubble curtains. If several conduits are deployed simultaneously, this improved noise protection can be installed in a single passage of the ship around the pile-driving site. In some embodiments of the invention, the number of conduits deployed simultaneously can be approximately 2 to approximately 6.
  • several cables can be deployed simultaneously by unwinding each cable from an associated winding device, which unwinds the cables at different speeds. If the winding devices each have drums of the same diameter, the rotational speed can be selected differently. According to the invention. It was recognized that the cables would lie spaced apart on the seabed. For example, in some embodiments of the invention, the speed can be selected such that the cables are arranged essentially concentrically, with the outer cable laid with a radius that is approximately 10 m to approximately 30 m larger than the radius of the inner cable.
  • the drum of the winding device has an internal air supply, so that the cable can be pressurized with compressed air during unwinding and/or retraction.
  • This provides additional mechanical stabilization to the cable, preventing it from experiencing excessively small bending radii that could damage it. Furthermore, it prevents the ingress of seawater and sand, which could clog individual bores in the cable wall.
  • Figure 11 shows a hose 11 which can be used as a conduit 10 in a soundproofing device 1 according to the invention.
  • the hose 11 can form at least a longitudinal section of the conduit 10.
  • the conduit 10 can be formed entirely by the proposed hose.
  • Hose 11 has a wall 111, which is determined by Figure 4 This will be explained in more detail.
  • the wall 111 encloses the clear width 116 of the hose 11.
  • the wall 111 can be made of rubber or a polymer.
  • the wall 111 can contain or consist of polyvinyl chloride or EPDM.
  • the wall 111 can contain at least one wire mesh 112, 113, or 114.
  • Figure 4 Figure 1 shows an embodiment with three approximately concentrically arranged layers of wire mesh. These can be inserted into the wall 111 during extrusion or vulcanization of the tube 12.
  • the number of wire mesh layers 112, 113, and 114 can be larger or smaller, ranging from approximately 1 to approximately 7.
  • one wire mesh layer can also be omitted.
  • the wall 111 has a plurality of bores 105, one of which has a cross-section of Figure 4
  • the bores 105 can have a diameter of approximately 0.5 to approximately 5 mm.
  • the bores 105 can be arranged at intervals of approximately 100 cm to approximately 10 cm in the wall 111.
  • a chain with a plurality of chain links 102 is used as the weighting element 101.
  • the hose 11 or the line 10 remains flexible, so that it can be easily wound and unwound, and thus laid on and removed from the seabed in a particularly simple manner. Even if the chain 101 fills a large part of the clear opening 116, the compressed air can still flow through the line 10 between the links 102.
  • the chain 101, as well as the wire mesh 112, 113, and 114 can further increase the tensile strength of the line 11, thus preventing damage during the insertion and removal of the line 10.
  • the wire mesh 112, 113 and 114, as well as the chain 101 or another weighting element, can be made of corrosion-resistant or corrosion-resistant steel in some embodiments of the invention. This extends the service life of the line 10 if seawater enters the line during operation of the device through defects or through the bores 105.
  • Figure 1 shows a connecting element 40 with which different longitudinal sections of a hose 11 can be joined to form a single line 10.
  • the connecting element 40 has a sleeve 41.
  • the sleeve 41 consists of a cylindrical base body on the outside of which a plurality of ribs 45 are arranged.
  • the outer diameter of the cylindrical base body 41 corresponds approximately to the inner diameter 116 of the hose 11. In this way, the hose 11 can accommodate the cylindrical base body 41, with the ribs 45 lying against the inner wall 115.
  • the joint can be inserted into a clamp 43 designed as a half-shell.
  • the clamp 43 is then closed with a screw connection 47 via bores 44.
  • the clamp can have 43 cutouts. or have ribs 46 which are shaped or arranged complementarily to the ribs 45. In this way, a positive-locking connection of the hose 11 with the cylindrical base body 41 is achieved, so that high tensile forces can be transmitted in the direction of the longitudinal extension of the hose 11 without the hose 11 slipping out of the connecting element 40.
  • Figure 5 shows an application example of the soundproofing method or soundproofing device proposed according to the invention.
  • Figure 5 Figure 3 shows the tower of a wind turbine 3, which is anchored to the seabed 2 by means of a tripod 30.
  • the water depth at the installation site of the wind turbine 3 can be, for example, approximately 10 m to approximately 45 m or approximately 25 m to approximately 40 m.
  • the tripod 30 has mounting sleeves 31 at its base.
  • the mounting sleeves 31 are designed to receive a driven pile 32.
  • the tripod 30 is securely connected to the driven piles 32 and the driven piles 33 are securely anchored in the seabed 2, the wind turbine 3 stands reliably on the seabed 2.
  • the driven piles 32 can have a diameter of approximately 2 m to approximately 5 m and a length of approximately 20 m to approximately 40 m.
  • the piles 32 are driven in with a pile driver (not shown), generating high-intensity sound emissions 21 which propagate as structure-borne sound in the seawater.
  • the invention proposes to lay a conduit 10 in a ring shape around the pile driving point or around the entire tripod 30 with all pile driving points.
  • the conduit 10 is unwound according to the invention from a winding device 15, which is mounted on a ship 11 and is guided by the Figure 3 This will be described in more detail.
  • the pipeline 10 can be pressurized with compressed air from a compressor 18 during deployment. Due to the ballast inside the pipeline 10, it nevertheless sinks to the seabed under its own weight and remains there.
  • the pipeline 10 is pressurized with compressed air by at least one compressor 18 and a pipeline 181.
  • the compressed air 180 leaves the pipeline 10 through the openings 105 and rises to the sea surface in the form of bubbles.
  • the high-intensity sound emission 21 is attenuated as it passes through this bubble curtain 180, so that a lower sound intensity 22 is perceptible outside the area bounded by the pipeline 10.
  • the cable 10 can be retrieved and brought back on board the ship 11 using the winding device 15, and is then available for the next use.
  • the ship 11 can drift without propulsion or with minimal engine power while the cable 10 is being wound in using the winding device 15. This ensures that the ship 11 follows the path of the cable 10, similar to when retrieving an anchor chain, thus preventing any kinking of the cable 10 or wrapping of the cable 10 around the tripod 30.
  • the winding device 15 has a frame 151.
  • the frame 151 can have the external dimensions of a standard container, for example, the dimensions of a shipping container according to ISO 668. In this way, the winding device 15 can be transported and stored in a space-saving manner.
  • the frame 151 has the standard dimensions of a freight container, it can also have the connecting elements 153 of such a container, so that several winding devices 15 can be stacked on top of each other like containers, or mixed stacks of winding devices 15 and containers can be formed. This allows for a space-saving and cost-effective transport option on the ship 11.
  • a drum 152 is rotatably mounted in frame 151.
  • the drum 152 can be designed to hold more than 500 m, more than 900 m, more than 1000 m, or more than 1100 m of hose 11. Since the hose 11 is made of flexible rubber or plastic and has a smooth outer surface due to the internally arranged weights, the hose 11 can be stored on the drum 151 in a particularly space-saving manner.
  • the drum 152 can be set in rotation by a hydraulic drive (not shown) so that the hose 11 is unwound while the ship 19 circles the area designated for the noise abatement measures. Provided the drive of the drum 152 is sufficiently powerful, the ship 19 can be pulled backwards by the hose 11 to retrieve it, with the hose 11 winding onto the drum 152.
  • FIG. 3 A compressed air connection 154 is visible.
  • the line of a compressor 18 can be connected to connection 154, which supplies compressed air to line 11. Due to the compressed air connection of the hose 11 being located inside the drum, the hose 11 can be pressurized with compressed air even while it is being unwound.
