Abstract
The invention relates to a watercraft having a hull (10), an introduction installation (20) for an object (70) to be anchored in the water, said introduction installation (20) being disposed on said hull (10), and at least one compressor (30) having at least one compressed-air line (40) which leads into the water and is coupled to at least one compressed-air distribution installation (45) which has a horizontal extent and for generating a bubble curtain (50) below the hull (10) has a multiplicity of mutually spaced apart outflow openings (46), characterized in that the hull (10) has at least two sub-hulls (11, 12) which are disposed so as to be mutually spaced apart and connected to one another, and a void (15) which is at least partially surrounded by the bubble curtain (50) is situated between the sub-hulls (11, 12).
Claims23
A watercraft, comprising:
- a hull which comprises at least two sub-hulls which are disposed mutually spaced apart and connected to one another, and the hull at least partially encloses a void which is situated between the sub-hulls;
- an introduction installation for an object to be anchored in a bed of a body of water, said introduction installation being disposed on said hull;
- a first compressed-air distribution installation which comprises a multiplicity of mutually spaced apart outflow openings and is configured to be selectively lowered from the hull to the bed by holding elements and to extend, when on the bed, horizontally in a configuration that is circumferential about a location where the object has been or will be anchored, and;
- a second compressed-air distribution installation that comprises another multiplicity of mutually spaced apart outflow openings and is configured to be selectively lowered from the hull to the bed by other holding elements and to extending when on the bed, horizontally in a configuration about an external circumference of the hull;
- and
- at least one compressor which is configured to selectively pump compressed air into the first compressed-air distribution installation and the second compressed-air distribution installation, through at least one compressed-air line which is configured to extend to the first and the second compressed-air distribution installations on the bed, wherein
- the mutually spaced apart outflow openings of the first compressed-air distribution installation on the bed are configured to generate, when receiving the compressed air from the at least one compressor via the at least one compressed-air line, a first bubble curtain that rises from the mutually spaced apart outflow openings on the bed, vertically upward to an area of the hull which at least partially encloses the void and at least partially surrounds the introduction installation or the object to be anchored in the water, and
- the mutually spaced apart other outflow openings of the second compressed-air distribution installation on the bed are configured to generate when receiving compressed air from the at least one compressor, via the at least one of another compressed-air line, a second bubble curtain that rises from the mutually spaced apart other outflow openings of the second compressed-air distribution installation on the bed, vertically upward toward a surface of the water about the external circumference of the hull.
A compressed-air distribution installation for fastening to and lowering from a watercraft on a body of water, the watercraft having a hull comprising two sub-hulls which are disposed as mutually spaced apart with a void situated between the two sub-hulls, and the lowering being to a bed of the body of water, said compressed air distribution installation comprising:
- a first multiplicity of spaced apart compressed air outflow openings that, when the compressed air installation is on the bed of the water of water, are located on the bed at first positions along a first pattern that extends horizontally and circumferentially surrounding the void;
- a second multiplicity of spaced apart compressed air outflow openings that, when the compressed air installation is on the bed of the water of water, are located on the bed at second positions along a second pattern that extends horizontally and circumferentially surrounding an external circumference of the hull,
- wherein:
- the first multiplicity of spaced apart compressed air outflow openings are configured to generate, in response to receiving a compressed air from a compressed air line, a first bubble curtain that rises from the bed below the hull, from the first positions along the first pattern, vertically upward to the hull circumferentially surrounding the void, and
- the second multiplicity of spaced apart compressed air outflow openings are configured to generate, in response to receiving another compressed air feed from the compressed air line or another compressed air line, a second bubble curtain that rises from the bed below the hull, from the second positions along the second pattern, vertically upward to a surface of the body of water which is circumferentially about the external circumference of the hull.
