Definitions

  • the invention relates to a hydraulic noise suppressor for reducing water noise, in particular in the area of a construction site for an object to be introduced into an underwater bed, the hydraulic noise suppressor having an upper end and a lower end opposite the upper end, with side flanks extending between the upper end and the lower end are, wherein the hydraulic noise suppressor can be divided along the side flanks and is movable between a closed position and an open position, wherein the hydraulic noise suppressor has at least one support structure, wherein a lower end of the at least one support structure is movably fixed relative to the at least one floor element.
  • the invention further relates to a method for handling a hydraulic noise suppressor and/or for positioning a hydraulic noise suppressor in the area of a construction site for an object to be introduced into an underwater bed.
  • Hydraulic noise suppressors are known for reducing the hydro noise, also known as water noise, ie the noise in the water.
  • Underwater soil is the solid body of soil below a water column.
  • An underwater floor within the meaning of the present invention is a sea floor or the bottom of a harbor basin or inland water such as a lake or a river.
  • the objects that are often introduced into the underwater soil during underwater work are foundation bodies such as piles or structural parts such as wall elements that are introduced into the underwater soil by means of drilling or ramming.
  • other sound-emitting devices such as a drill pipe are to be understood as an object to be introduced into the underwater bed.
  • Underwater noise such as that generated during the underwater work described, can be perceived over long distances by marine mammals, such as porpoises and seals. Underwater noise primarily affects those animals that use their hearing not only for communication but also for orientation and foraging. Permanent hearing damage in these animals can result in death.
  • enveloping bodies made of elastic material can also be used as noise reduction elements.
  • a large number of noise reduction elements are arranged on a support structure. This is, for example, a net that can be stretched flexibly around the sound source in the water. The nets are held in place with weights on the underwater floor.
  • the entirety of the noise reduction elements with the support structure is called a hydraulic silencer.
  • a hydraulic silencer has an additional dampening effect and can be precisely matched to the expected sound spectrum.
  • a hydraulic silencer is less susceptible to sea currents and is optimally effective in the entire relevant frequency range.
  • a continuous compressed air supply is not required for a hydraulic silencer, as is the case with a bubble curtain.
  • a hydraulic silencer is known. This consists of a variety of mutually spaced damping elements to reduce hydronoise, which are distributed on a Support structure, for example on a network, are arranged.
  • the support structure is arranged around a sound source at the point of use.
  • a sound source is, for example, a pole that is inserted into the underwater floor, which can be done by ramming or drilling.
  • the generic DE 10 2004 043 128 A1 relates to a pole guide device for guiding a pole which is to be rammed into a body of water and which is enclosed by an inner and an outer textile curtain, so that the bubbles emerging from a nozzle arrangement rise between the two textile curtains.
  • blow-out openings are located in the radial direction between the inner textile curtain and the outer textile curtain. Since the bubbles escaping and rising from the blow-out openings cannot pass through either of the two textile curtains, they remain concentrated in the tubular space between the two textile curtains until they reach the water level.
  • the nozzle assembly consists of two rigid legs connected by two hinges so that the nozzle assembly can be opened to insert the pile sideways into the nozzle assembly. Thereafter, the movable legs are each closed so that the pole is enclosed and fixed in its correct position.
  • the DE 10 2012 206 907 A1 shows a device for reducing the propagation of sound, vibrations and pressure surges in a liquid when introducing an object into a subsurface with several damping bodies that can be filled with a gas and a carrier on which the damping bodies are arranged in a suitable relative position to one another.
  • the carrier has a frame with mutually perpendicular vertical and horizontal linkage elements which is movable between a closed position and an open position by means of joints.
  • the frame areas constructed from horizontal linkage elements can be coupled to one another via cables in order to enable particularly space-saving storage or space-saving transport of the device when it is not in use.
  • the pamphlet WO 2013/102459 A2 describes a method and a device for handling a hydraulic noise suppressor in the area of an offshore construction site, in particular when a pile is to be inserted into the underwater soil.
  • the disclosed device comprises a holding device on which a first end of the hydraulic noise suppressor is held, and a second end of the hydraulic noise suppressor which is remote from the first end of the hydraulic noise suppressor and which can be positioned movably relative to the holding device, in particular remotely from the holding device.
  • the GB 2509208A refers to such a rigid acoustic enclosure.
  • the invention is based on the object of creating a way of simplifying both the handling of a hydraulic noise suppressor to reduce the generation or spread of hydraulic noise and the handling of the object in the field of underwater work such as drilling or ramming an object into the underwater soil, so that the Workflows can be carried out quickly, safely and ultimately cost-effectively.
  • the hydraulic noise suppressor has noise reduction elements that are attached to the at least one support structure and are spaced apart from one another, with the support structure being formed from a row of several parallel vertical cables and/or net strips and/or net hoses and/or a net equipped with the noise reduction elements. Both the handling of the hydraulic noise suppressor and the handling of the object are easier than with known hydraulic noise suppressors.
  • the side flanks can be moved relative to one another between two end positions, an open position and a closed position.
  • a body that extends deep into the water for example a vertically held pole, can be brought quickly and easily into the area sealed off by the hydraulic noise suppressor.
  • the closed position the side flanks are positioned at a small distance from one another, touching one another and/or overlapping one another.
  • the open position the side flanks are spaced far apart, which is greater than the cross section of the object.
  • the mutually movable side flanks belong, for example, to a single support structure and/or to separate support structures which, for example, consist of a number of parallel vertical cables and/or net strips equipped with noise reduction elements and/or net hoses are formed, which are held at the lower end on a floor element and float freely at the upper end.

  • Support structures in the form of cages can also be telescopic or arranged one on top of the other and/or next to one another, for example stackable.
  • the upper end and the lower end of the at least one support structure can be moved translationally relative to one another in a vertical direction and/or in a horizontal direction approximately perpendicular to the vertical direction. This makes it possible to assemble the support structure for moving the hydraulic noise suppressor between the open position and the closed position or for moving the hydraulic noise suppressor to another location and to stow it safely in a transport housing.
  • the hydraulic noise suppressor comprises at least one base element, which is assigned to the lower end of the at least one support structure, the lower end being movable relative to the at least one base element or being fixed to the at least one base element.
  • the at least one floor element can be moved translationally in a vertical direction relative to the holding elements, so that the at least one support structure can be spread out or gathered together by means of the vertical movement of the at least one floor element. This is possible by attaching the lower end of the support structure to the floor element.
  • the vertical mobility of the at least one floor element is advantageous since the at least one floor element can be lifted from the underwater floor when the hydraulic noise suppressor is displaced, which makes handling the hydraulic noise suppressor easier.

  • an object is moved by an introduction device into the introduction position. Afterward a guide device and at least two holding elements of the hydraulic noise suppressor are moved from an open position to a closed position, the object being held horizontally immovably by the guide device and enclosed by the holding elements. Then, the hydraulic noise suppressor is spread while moving a lower end of the hydraulic noise suppressor to the underwater bottom or to a bottom member resting on the underwater bottom. The object is then introduced into the underwater bed using the introduction device. The hydraulic noise suppressor is then at least partially contracted, with the lower end being moved away from the underwater bed.

  • the bottom element 12 is designed as a transport housing 16 which accommodates the support structure 5 with the noise reduction elements 10 outside of the water 3 .
  • the transport housing 16 is preferably an open-topped lattice cage. If the floor element 12 is lowered into the water 3, the noise reduction elements 10 float up.
  • the support structure 5 and noise reduction elements 10 are pulled down to the underwater bottom 2 and thus spread out over the entire water column.
  • the upper end 7 of the support structure 5 floats freely on the water surface.
  • the holding elements 11 are fixed to the guide device 15 by means of ropes or shackles. After positioning the object 1, the hydraulic noise suppressor 4 is closed.
  • the bottom element 12 After closing, the bottom element 12 is lowered.
  • the opening and closing of the hydraulic noise suppressor 4 is preferably carried out above the water level, with the noise reduction elements 10 receiving no buoyancy.
  • figure 26 shows a special embodiment of a hydraulic noise suppressor 4, in which a floor element 12 has been placed on the underwater floor 2.
  • Numerous support structures 5, which are also independent of one another, with noise reduction elements 10 are arranged on this floor element 12.
  • the support structures 5 are connected with their lower ends 8 to the floor element 12 which suppresses the support structures 5 and noise reduction elements 10 from rising further.
  • the support structures 5 consist of individual ropes or narrow strips of netting or are individual tubular netting, inside which the noise reduction elements 10 are arranged.
  • Each of the support structures 5 has a side flank 6 to the support structures 5 adjacent to it.
