Definitions

  • the invention relates to a soundproofing device for piling under water, comprising at least one fixable on the seabed line having a plurality of bores, and at least one compressor with which compressed air in the line can be introduced so that it can escape from the holes. Furthermore, the invention relates to a method for reducing the transmission of sound in a liquid, comprising the following steps: applying a line to the seabed, which surrounds the sound source in an annular shape and is provided with holes and introducing compressed air into the conduit so that they pass through the holes exit.
  • Such devices and methods can be used for sound insulation when introducing cylindrical piles in the seabed.
  • Such piles can be used to anchor monopile, tripod, tripile or jacket constructions on which structures such as wind gauges, wind turbines, offshore oil rigs or substations can be established.
  • the above foundation structures can be largely prefabricated on land, so that often on-site easy and quick to install in difficult weather conditions.
  • the disadvantage is that heavy ramming devices are required for the construction, which introduce a large sound level of, for example, more than 130 dB into the environment. Such sound levels can be harmful to the marine fauna.
  • the invention is therefore based on the object of specifying a device and a method for piling under water, which combines a good soundproofing effect with low equipment costs, so that the soundproofing measures can be performed quickly and easily.
  • the object is achieved by a soundproofing device according to claim 1, a hose according to claim 8 and a method according to claim 12.
  • air bubbles are allowed to rise from a conduit for sound insulation during the pile work in a manner known per se, which surrounds the pile in an approximately annular manner. Due to the density inhomogeneity between the rising air bubbles and the surrounding seawater as well as due to the compressibility of the Air bubbles can be at least partially dissipated the energy of the sound waves, so that outside the bubble curtain a lower sound intensity prevails.
  • the line can be applied so that it surrounds the ram completely annular. If a reduction is required only in certain directions, of course, the line can be designed only in these directions or the ring to the ram not completely closed.
  • the compressed air emerging from the line is provided by at least one compressor, which is usually mounted on the water surface on a ship or a jack-up barge.
  • the compressed ambient air is then supplied to the conduit via a supply hose and exits the conduit via a plurality of bores which are introduced along the longitudinal extent of the conduit.
  • the total weight of the line is increased so far that it remains without further anchors or external additional weights on the seabed. Since the weighting body is mounted inside the line, the outer shape of the line remains unchanged, so that they can continue in a simple manner off and / or introduced without external weights hindering the process.
  • Anchoring by divers may be additional but is usually not required. At least the number of anchors can be reduced or the distance of the anchoring points can be increased, since the line remains due to their high weight on the seabed.
  • the weighting body may include a metal or alloy in some embodiments of the invention.
  • the weighting body may contain or consist of a mineral material, for example concrete.
  • the or the weighting bodies can be introduced directly into the production of the line, for example by extrusion.
  • weighting bodies can be glued, screwed or riveted at certain intervals in the line.
  • a plurality of weighting bodies may be connected to one another by a wire rope or a chain, which prevent slippage along the longitudinal extent of the line.
  • at least one sufficiently dimensioned chain with a plurality of chain links can be used as the sole weighting body.
  • Such a weighting body can be easily introduced into the line. Due to the mobility of the chain links of the weighting body does not affect the winding and unrolling of the line or only slightly.
  • the conduit may comprise at least one longitudinal portion having a tube with a wall, the wall containing at least one layer of wire mesh.
  • multiple layers of wire mesh may be present in the wall.
  • the number of layers of the wire mesh may 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, so that a mechanical damage or a non-tolerable cross-sectional or length change during unwinding of the tube is avoided.
  • the wire mesh can limit the elasticity of the tube, so that it retains its desired cross section even at high pressure. Thus, the device can be operated with greater reliability and be safely out and introduced.
  • the wire mesh and / or the chain or the at least one weighting body may contain or consist of a stainless steel.
  • a stainless steel is to be understood as meaning an alloyed steel which is corrosion-resistant or at least resistant to corrosion.
  • steels with the material numbers 1.4401, 1.4571 or 1.4462 can be used. The use of these stainless steels extends the life of the proposed device if seawater gets in contact with the weighting body and / or the wire mesh through the air outlet openings or damage to the wall.
  • the soundproofing device further comprises at least one winding device with at least one drum on which the line can be wound up.
  • the drum may have a drive, such as an electric or hydraulic drive.
  • the drum may be configured to receive more than about 900 meters, more than about 1000 meters, or more than about 1100 meters of conduction.
  • the conduit to receive the conduit after completion of the work, it may be sufficient to roll the conduit onto the drum while the vessel is propelling substantially idle or with low engine power.
  • the ship is guided by the line as on an anchor chain and follows the course of the line backwards, while the line is wound onto the drum.
  • a line with increased tensile strength as the proposed embodiment with at least one wire mesh in the wall proven.
  • the weighting body can serve to absorb tensile forces, if this contains or consists of a chain or a wire rope.
  • a plurality of lines can be applied simultaneously, each of which surround the sound source in an annular manner.
  • a plurality of approximately concentrically arranged bubble veils are formed. Since a single veil of bubbles from a single line causes a reduction of the sound by about 12 dB to about 20 dB, a number of bubble veils can result in a correspondingly greater reduction. If multiple lines are deployed at the same time, this improved sound insulation can be installed with a single ride of the ship around the pile.
  • the number of concurrently applied lines may be from about 2 to about 6.
  • multiple lines may be deployed simultaneously by unwinding each line from an associated winding device which unwinds the lines at different speeds. If the winding devices each have drums with the same diameter, the rotational speed can be chosen differently for this purpose become. According to the invention, it has been recognized that the lines come to rest on the seabed at a distance from each other. For example, in some embodiments of the invention, the speed may be selected to be substantially concentric with the conduits laid with a radius that is from about 10 meters to about 30 meters greater than the radius of the inner conduit.
  • the drum of the winding device may have an internal air feed, so that the line can be supplied with compressed air during unwinding and / or during retrieval.
  • the line is additionally mechanically stabilized so that it does not experience unacceptably small bending radii, which could damage the line.
  • the penetration of seawater and sand is avoided, which could lead to clogging of individual holes in the wall of the pipe.

  • the number of wire meshes 112, 113, and 114 may be greater or less and may be between about 1 and about 7.
  • a wire mesh may also be omitted.
  • the wall 111 has a plurality of bores 105, one of which in cross section of FIG. 4 is shown.
  • the bores 105 may have a diameter of about 0.5 to about 5 mm.
  • the holes 105 may be arranged at a distance of about 100 cm to about 10 cm in the wall 111.
  • a weighting body 101 in the illustrated embodiment a chain with a plurality of chain links 102 is used.
  • the tube 11 or the conduit 10 remains flexible, so that it can be easily rolled up and down and so can be designed in a particularly simple manner on the seabed and removed there again. Even if the chain 101 fills a majority of the clearance 116, the compressed air can still flow between the links 102 through the conduit 10.
  • the chain 101 as well as the wire mesh 112, 113 and 114, the tensile strength of the line 11 further increase, so that damage during insertion and removal of the line 10 can be avoided.
  • the wire mesh 112, 113 and 114 and the chain 101 or other weighting body may in some embodiments of the invention be made of corrosion-resistant or corrosion-resistant steel. As a result, the life of the line 10 is extended, if in the operation of the device by damage or through the holes 105 seawater enters the line.
