Method for handling a hydro sound absorber, and device for reducing underwater noise

摘要

A method for handling a hydro sound absorber in the region of an offshore construction site. The method includes, prior to beginning noise-emitting work, positioning a hydro sound absorber in the region of the offshore construction site. The method includes positioning a transport housing receiving the hydro sound absorber close to at least one of a seabed or a surface of the water. The method also includes spreading out the hydro sound absorber from a first functional position out of the transport housing at least one of vertically to the extent of the offshore construction site or horizontally to the geometry of the seabed.

1. A method for handling a hydro sound absorber in the region of an offshore construction site, the method comprising:
prior to beginning noise-emitting work, positioning, close to at least one of a seabed or a surface of the water, a transport housing storing a hydro sound absorber in a contracted first functional position, the transport housing being permeable to water and the hydro sound absorber, which comprises a carrier structure and sound reduction elements fastened to the carrier structure, having a first end and a second end remote from the first end; spreading, at least one of vertically to the extent of the offshore construction site or horizontally to a geometry of the seabed, the hydro sound absorber out from the contracted first functional position to an at least partially spread-out second functional position; and holding, by a holding mechanism, the first end of the hydro sound absorber while the second end of the hydro sound absorber is movable relative to the holding mechanism, wherein the sound reduction elements fastened to the carrier structure are spaced apart from one another in the at least partially spread-out second functional position, and wherein the transport housing is directly connected to at least one of the first end of the hydro sound absorber or the second end of the hydro sound absorber.
