Description

Device for controlled swimming in and out of a barge in in or out of a barge mother ship The invention relates to a device to swim a barge out of the moving sea into a takeover position in a Gate of a barge mother ship. The device also allows swimming from the barge mother ship to the turbulent sea .__-.--.

A coffin that has been floated in is in the takeover position of a Ship crane device hoisted into the ship and stowed away.

The commonly practiced type of takeover or delivery of floating bodies the barges are called, from or on the moving sea is with considerable Associated with risks. The risk is not just related to the dangers for the person involved Personnel but also for any damage to the ship and barge as well as to the Envelope dishes.

It is known that the barge mother ship (so-called barge carrier) in usually with a on deck in the ship's longitudinal or. Cross-direction movable bridge crane is equipped, which is either via a central gate or at the stern of the ship Cantilevers a barge receives or releases. The barges when loaded have a weight of up to 500 t and more, with the help of the ship or On-board cranes raised so far above the water level that they can be lifted over the stern or Side wall of the ship taken over and moved by the longitudinal and transverse ship The crane can be brought into stowage position. The striking, i.e. Establish the connection between the barge and the crane harness with the help of the envelope harness that When the bulk and crane connect with one another, it turns out to be difficult when the cargo and ship move relative to one another due to the swell carry out. This stopping process is particularly difficult when the barge cannot be firmly connected to the ship by means of devices.

Several ways have been suggested to solve this problem. Of the one assumes that current conditions and swell are only insignificant Have an influence on the Umsohlagsvorgang, so do not fix the barge can, and that the hitting is therefore relatively easy to accomplish leaves.

But that means that loading and unloading are relatively quiet Water has to be carried out, i.e. in harbors or estuaries without high flow velocities and with a low tidal range. This makes the operational potential of the ship essential restricted.

Another known solution provides, with the help of a movable on the ship Attached pontoons underpin the barge, with the pontoon by means of fed Compressed air receives buoyancy, so to raise the Darge above the surface of the water able.

The main disadvantage here is that such a device requires a relatively high level of effort, although this has not yet been adequately clarified is whether this device can be made stable enough in heavy seas, in order to work reliably with it. Another well-known solution wetr consists in moving the coffin into the desired takeover position with the help of ropes and winches to maneuver and hold on there. As already mentioned at the beginning, this path is associated with considerable risks. Especially catching the barges when the sea is rough Using ropes is a simple matter and requires great skill by the personnel involved and is, in terms of the time required, quite uninhibited . , .._ -.

According to the basic idea of the invention, one or the other is known Deliberately leave the solution and instead use a push boat or Tug in the Td, "ihe of the ship carried barre through more or less Directed generated water streams captured in the desired takeover position funneled and held there. For this purpose, means for generating wax currents are used used.

Hittel of this type are, for example, Voith-Schneider propellers or known as Kort nozzles. Pumps or the propeller itself can also be used used to create water currents.

The known application of a directionally generated water flow is limited on an aid measure in the conventional hooking up of a fishing net on fishing mother ships. The known net haulage measure is dragged in by a winch, whereby the envisaged jet propeller in the manner of a Voith-Schneider propeller are adjustable and generate a flow of water that facilitates the entry process. the The object of the invention is to dispense with the conventional barge recovery means to provide a device through which the barge can safely approach the Mothership, both in calm 31s and in rough seas and beyond unfavorable wind and current conditions, an e x a lc t e s floating in the Barge in the stern or bow or side gate of a mother ship up to the takeover position is ensured.

The invention is based on a device for floating a Barge in a takeover position in a gate of a barge mother ship and with Means for creating currents of water.

The invention is that the barge by one or more with the help of jet-generated water currents during the approach and / or infiltration g e t e u e r t movable and held in the takeover position g e t e e r t e r t is.

The Darge can be in the area between the propeller and at least a stern nozzle swam in by a directed water jet of primary flow will.

According to a further feature of the invention, the water flow generated by a pump system on the ship. It is also possible at least to use a Kort nozzle that can be rotated around a vertical and / or horizontal axis is, with the dilsen opening wholly or partially arranged below the waterline is. The aforementioned means all generate water jets primary flow, whose directed water forces the mountains in the sense of a direct control infiltrating.

It is also possible not only to control the infiltration of the mountains to undertake, but also to catch the from the Schlepper.bzw. Push boat gelrisien - barge. For this purpose, according to a further feature of the invention, the mountains are used at least two parallel and spaced Kort nozzles by water currents secondary flow axially swam into the takeover position.

It is also possible to swim the barges into the takeover position by means of directed water jets of secondary and / or primary flow with the aid of at least two parallel and spaced-apart nozzles rotatably arranged around a vertical and / or horizontal axis. : According to the last-mentioned solution, both the capture, the transfer and the holding process are possible with one and the same flow-generating means.

A secondary flow can also be achieved by the Eiarge with the help of a number of parallel and spaced apart Nozzles by directed water jets of secondary flow in the takeover position is swum.

By means of a modified method, the mountains can also be moved in a controlled manner with the help of propeller and / or deflected Ilchiffeanttriebechscrews generated symmetrical and additionally directed against the stern of the ship during the approach and / or inward transfer and in the takeover position; be kept controlled.

It is also possible to generate the ßarge with the help of suction Devices, in particular pumps, during the approach and / or introduction to move in a controlled manner and to keep controlled in the takeover position.

The water currents are directed --- sized and they are also during the approach phase of the swim-in process in their direction; sc changeable, that an exact swim-in is guaranteed. The holding position is the same the Darge., which is at the same time the takeover position, of the generated water currents influenced in such a way that the barge thereby assumes a position of rest, and that without Difficulties as well as operationally reliable the barge associated with the takeover gear can be attached without hitching lines and using winches for mooring have to.

The device is in the opposite arrangement to that provided Means also to be used for floating the barge.

The means provided for generating the water currents controlling the barge can be arranged in such a way that they can only .naturally during seafaring the propeller; are arranged retracted.

Embodiments of the invention are shown schematically in the drawing illustrated and explained .. It zej.

In the illustration according to FIG. 1, a barge 11 is placed under the stern of the ship in the area between propeller 1 and one or more stern nozzles 2 moved and released from the (not shown) towing or pushing unit.

The pump system 3 installed in the rear sucks from above to below the water line leading suction line 4 water and leads it over the pressure line 5 of the fieck nozzle or nozzles 2. The barge; is from the one emerging from the stern nozzle 2 and reporting water jet primary "> tr (3muizrr directly acted upon in a controlling sense, it thus receives a feed in "Schleusriclituii" and is in the takeover position swam in to (in: lightly described way) with the (not shown) to be connected to the crockery. According to Fig. 2. is at the stern a Kort nozzle 6 rotatably arranged in the horizontal plane. Depending on the direction of rotation of the propeller 7 is either a primarily directed flow (see. Fig. 3a) Propulsive force on the side frame effective or with secondary flow (cf. Fig. 3b) the barge is caught, smuggled into the gate and into the takeover position swam in.

In the latter case, e-s - not necessary to bring the barge with you Help the pusher between propeller 1 and Kort nozzle 6 to move them can rather be entered in the direction of infiltration.

The arrangement and number of the intended nozzles as well as the fact whether you work completely or partially under the waterline, have a significant effect on the floating movement and holding measure of the barge. Both the primary as well as the secondary flow; (the latter to a lesser extent) produce the desired ones Control currents on the barge.
