Definitions

  • a display stand for six propulsion units for a ship used for laying oil and gas lines, each of which generates a horizontal thrust jet and for determining the direction the thrust jet is pivotable about a vertical axis.
  • the display status has a field for displaying an operating state of the drive unit.
  • a cathode-ray tube is provided for each drive unit, on which a line represents the beam vector of the respective drive unit, this line starting at the center of the cathode-ray tube and with its length serving as a measure of the thrust. The direction of this line indicates the beam direction.
  • the object of the invention is to take into account the problems resulting from ships in which the propulsion and control are effected with rudder propellers or pump jets to such an extent that it is also possible for a skipper who is not used to handling such ships after a short period of familiarization to be able to sail and steer such ships safely, even if he is facing a situation with such a ship that does not allow a long time to think about necessary changes in propulsion.
  • the drawing shows one and the same scoreboard, which is installed in the area of the ship's captain, several times, but with the reproduction of the propulsion of the ship in different operating states and correspondingly different sailing conditions of the ship.
  • This is a so-called liquid crystal display, and it is intended for a ship that is driven and controllable by means of two rudder propellers or pump jets.
  • Such ships and such drives themselves are generally known and therefore do not need to be explained in more detail in the present context. This should only be mentioned as an example of a pump jet drive that is required here.
  • the presupposed ship has two such facilities in one specified offset to the lateral center of gravity of the ship.
  • the symbol for each drive device on the liquid crystal display 1 is one of the two arrows 2, 3, the symbol for the ship itself is the filled-in ship boundary 4, its reference symbol is a fixedly arranged, unfilled ship boundary 5.
  • the ship boundary 4 symbolizing the ship itself is symmetrical arranged on both sides of a longitudinal line 6.
  • the computer should be informed of the points of application of the forces in relation to the lateral center of gravity of the ship and preferably some basic dimensions of the hull (length, width, keel shape, etc.). Since all these values are constant, they are permanently stored in the computer when the direction indicator is started. On the evaluation of external forces (flow, Wind, etc.), however, is not used due to the complexity of recording these values.
  • the individual forces of the systems are shown in the lower part of the display for control and a better overview.
  • the direction of the arrows 2, 3 for this purpose each of which is assigned to one of the two drive and control units (rudder propeller or pump jet) that are required in the case under consideration, indicates the thrust direction of the systems.
  • a bar graph is integrated in the shaft of each arrow, which corresponds to the engine speed and thus the thrust strength of the system.
  • the tips of the arrows indicate the coupling state, with an empty tip for a disengaged, a filled tip for a coupled state.
  • the actual function of the direction indicator is located in the upper part of the display.
  • the computer calculates the resulting total force from the individual forces according to the laws of "teaching the forces" and displays them in the form of a moving ship (filled ship contour) Outline of this ship (unfilled ship outline) and the path of the lateral point are shown as line 7.
  • the direction indicator is progressive so that the direction of light ship movements is easy to read. Small forces are shown proportionately larger than large forces.
  • Fig. 1 the idle state of the presupposed ship is shown with two drives arranged symmetrically to the ship's longitudinal center line in the stern in forward-facing but ineffective feed directions, which is for the Skippers without any longer thinking that the filled-in ship outline or ship boundary 4 as a symbol of the ship with the reference symbol in the form of the unfilled-in ship boundary 5 are congruent in the direction of travel, while the two arrows 2, 3 symbolize the drive devices in the direction of thrust are not filled in, i.e. neither show a coupling condition (unfilled heads) nor an amount of force (bar display) in the shaft of the arrows.
  • translatory ship propulsion is symbolized at maximum travel out of the position according to FIG. 1.
  • the clutches are engaged according to the filled arrow heads, the arrow shafts are fully filled, which symbolizes full thrust, the arrows 2, 3 point in the same direction to the front, which points to the same directional beam exits for the translatory movement of the ship forward, with the translatory ship movement forward as offset of the shows the filled-in ship contour 4 towards the front in relation to the unfilled-in ship symbol 5 remaining in place.
  • FIG. 4 an operating state of the drives is shown with the aim of turning the ship on the spot with the stern swinging more strongly to starboard.
  • the port drive (arrow 2) is stopped and / or not engaged, which results from the left arrow 2, which has not been filled in as a whole.
  • the starboard drive (arrow 3) has a jet outlet direction to starboard, brings the propulsion for about half a trip and is engaged, both of which can be seen from the filled-in head of arrow 3 and the bar display in the shaft of arrow 3.
  • the stern of the ship (symbol 4) is pushed away from the reference symbol 5 to port to turn the ship accordingly.
  • the fact that the decommissioned port drive is pivoted in a propulsion direction to starboard serves the purpose of stopping the turning maneuver.
  • FIG. 5 shows a maneuver that could only be carried out by a skilled skipper without problems without the help according to the invention.
  • the ship symbol 4
  • the control maneuvers for the two drives can only be carried out by observing the arrows 2, 3 as symbols for the working strength and direction of action of the drives and monitoring the movement of the ship by observing the movement of the symbol 4 relative to the symbol 5.
  • the invention is a reliable aid for maneuvering a ship with a rudder propeller or Pumpjet propulsion, which even an experienced skipper will not want to do without after a certain period of familiarization.
  • the device according to the invention can also be used well as a training device in order to introduce shipowners in training to the problems of guiding ships with rudder propeller or pump jet propulsion or to familiarize them with them.
