    摘要： A dredging apparatus (24) works on the seabed (14). It is especially intended for the removal of cuttings gathered around a bore hole mouth at seabed (14), the removal being carried out by means of an ejector (30, 40) having coupled thereto a suction hose (32) and a conveyor pipe (34), respectively, for moving the cuttings to another place on the seabed (14). The dredging apparatus (24) comprises a drive motor (22), a pumping device (38) and an ejector (30, 40), the drive motor (22) being adapted to drive the pumping device (38) which, in its turn, is adapted to deliver a forced flow of water to the ejector (30, 40) in order to establish and maintain the ejecting effect. In order to avoid the pumping-down of enormous amounts of water to large depths by means of a motor-driven pumping device in a surface position, which is particularly energy, weight and space demanding on board of the rig, the ejector (30, 40), pumping device (38) and drive motor (22) are assembled to form a unit. A cable (20) delivers energy to the motor (22) from the surface.

    摘要： Method related to the hydraulic dredging of sediment from the sea bottom, the bottom of water dams or the like, inclduding a first operational step where sediment is sucked or pumped through a hose or pipe (2) to a second level located below the natural water surface utilizing the difference in water pressure between the natural water surface and said second level to provide or enhance the required suction or pump capacity. At said second level sediment is received in a container (3) accessible by mechanical equipment located at or over the natural water surface, from which container at least part of the sediment is removable by per se conventional pumps or conventional lifting methods or by releasing sediment to a lower level. At the lower end of said hose or pipe (2) a suction manifold (15) with two inlets or two sets of inlets (16, 17) is arranged, one inlet or set of inlets (16) being arranged at or close to the lower end of the suction manifold and being adapted to suck in sediment from the bottom together with some water, the other inlet or set of inlets (17) being arranged at a vertical distance from said first inlet or set of inlets (16) and being adapted to suck in water only.

    摘要： The present invention relates to underwater excavation of sediments and soils and simultaneous controlled movement of the excavated material. In particular, we will describe apparatus for bulk and selective excavation of sand, silt, clay and like materials from sea, river, canal and lake beds, and near-bed movement of the excavated material in a controlled fashion. Controlled, in this sense, refers to the direction and distance of movement and height of transport above the bed. The apparatus, at a smaller scale, may also be used for the removal of bio-fouling from vessels and marine structures; and at a smaller scale still, for hand-held underwater cleaning operations. We describe a fluid jet generating apparatus comprising swirling jet flow creating means. The apparatus suitably includes a duct having a fluid inlet (2) and a fluid outlet (3). In one embodiment, the apparatus comprises a propeller (5) mounted for co-axial rotation within the duct. In an alternative embodiment, the duct incorporates a static swirl generator (45) adapted to impart swirl to a fluid transmitted to the duct under pressure. The duct may further comprise a flared nozzle .(47).
