Definitions

  • the invention relates to a system for automatically setting up a line connection between a tugboat and another ship, in particular for setting up a line connection between a tugboat and a ship to be towed, according to the preamble of patent claim 1.
  • the invention also has a tugboat and a method for setting up a line connection and a method for breaking down a line connection to the subject.
  • Tugboats are a key component in the port economy. They keep seagoing vessels manoeuvrable, which, even because of their size, are unable to maneuver at low speeds. When ships are being towed, the challenge is regularly to set up a reliable and safe line transfer between a tug and the ship to be towed and to release this after the towing has been completed.
  • a ship's employee of the ship to be towed throws a heaving line onto a rear deck area of the tug.
  • the heaving line is picked up by an employee of the tugboat and connected to a hauling line of a towing cable.
  • the towing cable is transferred to the ship by the towing winch.
  • the ship's employee pulls the heaving line back onto his ship, which takes the tow rope with him, which he then fastens to a bollard on the ship.
  • the ship's employee lowers the towing cable himself in a controlled manner and finally throws down the rest of the hauling line connected to the towing cable, so that the line connection between the tug and the ship is released.
  • the tugboat employee then disconnects the line connection or, after throwing down the hauling line, he begins to disconnect the line connection, whereby the towing cable is caught up using a towing winch and this is prepared by the tugboat employee for the next towing operation.
  • the tugboat employee shoots a catch line or leader line or launch line onto a deck area of the other ship with a line launcher.
  • a line launcher can also be used in the area of tugboats, however, with this method there would be a risk of injuries to the ship's employees from the approaching hauling line.
  • Systems without a heaving line are also being considered, in which the hauling line is transferred from the tugboat to the ship by means of a drone.
  • this procedure also carries a high risk of injury.
  • the use of the line launcher and the drone is sensitive to wind and sea conditions.
  • a system for producing a line connection of a ship with a tugboat in which a heaving line is thrown over guiding elements projecting into the air and guided by them into a connection zone using gravity.
  • the pamphlet WO 97/11876 discloses a device for retrieving a towline fired in an emergency.
  • a system for making a line connection is known which has an erectable mast with arms for catching a heaving line.
  • the object of the present invention is to create an alternative system for establishing a line connection of a tugboat that has a high level of safety. It is also an object of the invention to provide a method for establishing a line connection between two ships and a method for dismantling a line connection between two ships.
  • a system according to the invention serves to automatically set up a line connection between a tugboat and another ship.
  • the system has a positioning device, a transfer device and an adapter device.
  • the adapter device is set up to be directly or indirectly connected to a towing cable.
  • the towing hawser or a catch line connected to the towing hawser can be fastened or to be fastened to the adapter device.
  • the positioning device is set up to align a section of a heaving line of the other ship that has been dropped onto a deck area of the tugboat (and is therefore located there, in particular resting there at least partially, i.e. making stationary contact with the deck area) relative to the adapter device, i.e. the adapter device and the section into one intended position (position and location) to bring relative to each other.
  • the deck area is to be understood as an area of the tug's deck, ie a part of an area or a combination of (possibly stepped) areas which close off the top of the tug's hull during use of the system; the statements "above” and “below” and terms derived therefrom refer in this document to an intended resting position of the floating tugboat.
  • the deck area faces the open sky, so that the Section of throw line can be dropped onto deck area.
  • the deck area can be covered, for example by means of an openable tarpaulin.
  • the deck area may include a drop (i.e. a portion that is lower than at least one other portion of the deck area) and/or it may be defined (as a whole) as a drop compared to other areas of the deck adjacent to it (e.g. the Working deck) be trained.

  • a holder 40 for the adapter device is arranged on the longitudinal slide (here in its center (in relation to its length)), so that the adapter device can be moved with the longitudinal slide towards the rear edge 7 .
  • the slides of the system 1 shown are designed as two opposing transverse slides 36a, 36b in the form of drivers that can be displaced along a rail. They are set up to be moved in opposite directions of movement (towards or away from each other) in the transverse direction of the tractor 2, preferably in such a way that they both cover the same displacement distance in the case of opposite displacement directions.
  • the directions of movement of the transverse slides in the present case therefore run orthogonally to the direction of movement of the longitudinal slide.
  • the transverse slides are set up to move towards each other in the course of alignment (of the section of the heaving line and the adapter device relative to one another) over the mentioned gap between the longitudinal slide and the rear edge 7 of the open catching space 6 and finally close the part of the section of the throwing rope on the adapter device between them hold so that the transfer device can transfer the section to the adapter device (not shown).
  • the transverse slides 36a, 36b can preferably be controlled independently of the longitudinal slide 32 and/or independently of one another.
  • the deck area 5 can thus be traversed by the positioning device 14 over its entire surface, so that the section of the heaving line is reliably detected when it is located in the deck area.
  • the transverse slides like the rail on which they can be slid, are arranged under the edge which is raised compared to the deck area 6 and which surrounds the deck area and can form part of a working deck of the tugboat 2, for example. In this way, it is prevented that the heaving line 8 hits the transverse slide or the rail when thrown onto the deck area 5 and possibly gets caught on them.
  • the figures 2a , 2 B show the system 1 in a partial view, wherein in the Figure 2b various elements are shown transparently for better visibility.
  • the positioning device 14 with various structural elements for holding and moving the longitudinal slide 32 and the transverse slide 36a, 36b and the transfer device 34 are visible.
  • the holder 40 can be seen, which is designed here as a pocket into which the adapter device 38 is inserted.
  • the adapter device can thus be moved with the longitudinal slide 32, as with reference to the above figure 1 was described.
  • FIG. 12 also shows a transfer device 34 of the system 1, which is preferably arranged in a stationary manner on the (for example, rear) edge of the catching space and comprises a claw-like transfer element 35 that can be moved toward the adapter device 38.
  • a suitable alignment of the (in the figures 2a , 2 B (not shown) section of throw line 8 relative to adapter device 38 and to transfer device 34 (in particular in such a way that transfer device 34, part of the section of throw line 8 and adapter device 38 are arranged in a straight row in front of one another), the section of throw line 8 can be replaced by a Movement of the transfer element 35 are passed to the adapter device 38 back to this.
  • the Figure 2b shows the arrangement from a different perspective.
  • the rail 37 can be seen therein, on which the transverse slides 36a, 36b (of which in Fig Figure 2b only the transverse slide 36a is visible) are displaceable.
  • the rail is preferably arranged at the rear edge of the catch space 7, namely - as above with reference to figure 1 described - below the edge that delimits it and is raised compared to the cover area. in the in Figure 2b
  • the longitudinal slide is advanced up to the rail 37, so that a gap S is created between the rear edge of the catching space (not shown in the figure) and the longitudinal slide, through which the throw line 8 (not shown) runs.
  • part of the section of the heaving line thrown onto the deck area can be pushed along the gap between the adapter device 38 and the transfer device 34 and then transferred to the adapter device 38 by moving the transfer element of the transfer device, i.e. be connected to it (in the Figure 2b not shown). Since the adapter device 38 is connected directly or indirectly (via a hauling line) to a towing cable, a line connection between the tugboat and the other ship can be established in this way.
  • the positioning device has at least one transverse slide and one longitudinal slide, the at least one transverse slide being slidably guided on the longitudinal slide so that when the longitudinal slide moves, the at least one transverse slide is carried along.
  • the figure 3 shows a perspective view of the adapter device 38, which in this case has rounded corners and edges, which prevents the throw line and the safety line from being chafed.
  • the adapter device 38 is buoyant.
  • the adapter device has a central receiving slot Z, which is closed by elastically yielding, preferably spring-loaded clamping jaws 42 and into which the transfer device can press a part of the throw line section against the clamping jaws 42 in order to transfer the throw rope to the adapter device (not shown).
  • a monkey fist of the throwing rope hangs on the gap from below, so that the adapter device is connected to the throwing rope and can be pulled with it to the other ship (not shown) .
  • the adapter device 38 On the side opposite the receiving slot Z, the adapter device 38 has an eyelet to which the towing cable can be attached directly or indirectly (in particular via a hauling line) (not shown).
  • the heaping line 8 pressed into the receiving slot Z can be seen, which is still held by the transverse slides 36a, 36b on each side.
  • the transverse slide 36a, 36b are pushed apart, as in FIG figure 4 indicated by arrows, in addition the longitudinal slide 32 is pushed back so that the gap S is widened and the adapter device 38 can be pulled out of its holder 40 by the operator on the heaving line.
  • the Figures 5a to 5g illustrate a method for coupling a ship 4 to a tugboat 2 according to the invention, the method being an exemplary embodiment of an inventive Set-up procedure for automatically setting up a line connection of the tug with the other vessel.
  • the deck area 5 and the catching space 6, the base area of which is formed by the deck area 5, are arranged between the towing winch 12 and the rear of the tractor 2 in this exemplary embodiment.
  • the transfer device is located at the stern and the adapter device at the bow (in Figure 5a Not shown).
  • system according to the invention can also be arranged in the bow area of a tugboat instead of in the stern area, so that the deck area is preferably located between a towing winch and the bow of the tugboat; the transfer device is then preferably on the bow and the adapter device is on the stern of the heaving line.
  • the Figure 5b shows how the longitudinal slide 32 is pushed in the longitudinal direction of the tractor 2 to the rear edge 7 of the fishing space 6.
  • the longitudinal slide 32 has a holder 40 embodied here as a pocket for an adapter device 38 which is connected to the towing cable 19 (directly or via a hauling line).
  • the towing hawser 19 is unwound from the towing winch 12.
  • the longitudinal slide 32 thus guides the adapter device 38 to the rear edge 7 of the catching space 6 until it delimits a gap with it, through which the throwing rope 8 leads.
  • the adapter device 38 is guided with the part of the section of the heaving line 8 on the longitudinal slide 32 away from the transfer device 34 so that they do not interfere with one another when the adapter device 38 is subsequently released from its holder 40 .
  • the Figures 5i and 5j show how the employee 10 manually retrieves the heaving line 8 to the ship 4.
  • the adapter device 38 is being lifted out of its holder.
