Definitions

  • the invention relates to a method and an arrangement for safely translating personnel (persons) from one ship to another object, e.g. to an offshore wind turbine, to other offshore objects or to other ships and back.
  • the currently prevailing concept is a mooring maneuver in which the ship mounts directly to the wind turbine.
  • the ship is usually guided by devices and thereby limited in the degrees of freedom.
  • Access to the wind turbine (abbreviated WEA) takes place at a favorable moment directly from the ship (or its boom) on the ladder or a platform on the WEA. The moment is favorable when the relative movement between the ship and the WEA is as small as possible.
  • a second major disadvantage is that the accessibility of the WEA finds its limits in the wave heights prevailing at the site. Significant wave heights of around 1.5 meters are a limit for docking maneuvers in the context of "boatlanding" without shutting off the swell, which is very often exceeded on the North Sea in particular. The accessibility of wind turbines is only about 55% with these conventional access methods. A safe access with a significant wave height of 3 m would increase accessibility to 88%.
  • This mooring device for applying a ship to an object designated as a structure is described.
  • This mooring device comprises a generic arrangement for translating personnel with a trained as a jetty passenger transfer element at the bow of the ship.
  • the jetty is on rotatably mounted on one end and provided at the other end with a control device.
  • the control device is movable during docking with the help of the ship movement along the surface of the structure, and with it the end of the jetty.
  • This mobility of the end of the jetty is used to couple a designed as a locking device, arranged on the ship coupling element to a trained as a fastening device, arranged on the structure coupling element.
  • This jetty is not suitable for smaller vessels, in particular for ships with low Zulandung such as catamarans.
  • a more elaborate landing bridge is described in DE 199 46 899 A1.
  • This jetty for an offshore wind turbine includes a jetty for ships, a helicopter landing pad, and a shared pathway from the dock and landing pad to the facility.
  • the invention has for its object to develop a method and a generic arrangement that allow a secure translation of personnel not only in large and heavy vessels, but also in smaller vessels and by a much more compact design of the arrangement is achieved. Finally, the arrangement according to the invention should also be significantly less expensive and thus cause considerably lower costs.
  • an at least one of the two objects is arranged one end, at least vertically, movable person transfer element coupled to the other object.
  • the person transfer element as a whole is moved with the coupling to the other object with this and relative to the one object by being released due to the relative movement of the objects for vertical movement.
  • the person transfer element is moved overall first with the one object on which it is arranged, and later with the coupling to the other object with the other object. This allows a person to move from one of the two objects to the transfer element only and leave it again when the object from which the person leaves or moves on and the transfer element move vertically in the same way.
  • the personnel is transferred from one to the other object in the following steps: a) the personnel moves from the one object to the person resting on it
  • Person transfer element to the other object, and possibly d) the person transfer element without staff is decoupled from the other object and offset with the decoupling to the other object.
  • the person transfer element is at rest to one of the objects also implies that there may still be some relative movement. At rest in this case means that the relative movement is greatly reduced and / or minimized.
  • the personnel when coupling the person transfer element located at one object to the other object, the personnel are transferred from one another to the one object in the following steps: 1) the personnel transfer element without personnel is coupled to and coupled to the other object 2) the staff moves from the other object to the person-transfer element at rest;
  • the person transfer element with the staff is decoupled from the other object and offset with the decoupling to the other object, and 4) the staff goes from the person to the other object resting person transfer element on the other object.
  • An arrangement according to the invention for safely translating personnel (persons) from an object embodied as a ship to another object is suitable for carrying out a method according to the invention.
  • the inventive arrangement with the person transfer element is designed so that the person transfer element is released in total with the coupling to the other object due to the relative movement of the objects for vertical movement with the other object relative to the one object.
  • An embodiment of an arrangement according to the invention comprises a person transfer device with the person transfer element and a coupling device.
  • the person transfer device with the person transfer element is arranged on the one of the two objects.
  • the coupling device is provided with two coupling elements which can be coupled to one another, wherein one of the coupling elements is arranged on each of the two objects.
  • the person transfer device has a guide device on which the person transfer element is arranged to be vertically movable.
  • the person transfer device also has a holding device, by which the person transfer element in a position on the guide device is durable.
  • a first coupling element is designed as an element of the person transfer element, wherein the coupling elements are designed to be coupled to each other so that after coupling the person transfer element is released due to the relative movement of the objects for movement in the guide device of the holding device.
  • the first coupling element is e.g. formed as a section of the person transfer element or as additionally attached to the person transfer element element.
  • the person transfer element is basically vertically movable in the guide device and is held by the holding device with a certain holding force in a certain position and is brought back into this position. In this case, if necessary, further vertical movement of the person transfer element is made possible only when the holding force of the holding device has been overcome. This happens when the coupling elements are coupled to each other, ie the ship is coupled to the other object. After coupling, the person transfer element is moved vertically by the movement of the ship on the guide device. After decoupling, the movement of the person transfer element is stopped, ie it is put back in peace.
  • This principle i. overcoming the holding force with which the person transfer element is held on the guide device, with the coupling and the relative movement of the objects, allows a person to transfer to the person transfer element only when the person and the person transfer element move vertically in the same way. The same applies to leaving the person transfer element.
  • a person transfer device arranged on the ship is used.
  • the person transfer device and with it the passenger transfer element are moved with the ship.
  • the person transfer element is held by the holding device relative to the ship in a certain position at rest. The person can safely go to the person transfer element (step a)).
  • the relative movement is minimized or completely stopped.
  • the person can safely transfer to the other object (step c)).
  • the ship can be decoupled with the person transfer element, wherein the movement of the person transfer element is stopped at the guide device by the holding device (step d)).
  • the person transfer device can be arranged on the further object.
  • the translation of a person is first coupled and the passenger transfer element is released for movement in the guide device with the ship's movement (step 1)). Only then does the person go from the ship to the person transfer element (step 2)).
  • the movement of the person transfer element is initially possibly damped and brought to rest by the holding device (Step 3)), so that the person can then proceed to the further object (Step 4).
  • the coupling elements are designed as Reib gleich- and / or form-locking elements.
  • at least one of the two coupling elements is designed as an elastic element, in particular as a slightly elastic element. This allows a certain balance of horizontal movements between the ship and the other object.
  • the person transfer element comprises a conductor element and the guide device rails and / or support cables, on which the conductor element is arranged to be vertically movable.
  • the holding device has friction brakes and / or holding springs and / or buoyancy bodies and / or other opposing forces applying devices, by means of which the conductor element in a position or in a position range on the guide device is durable.
  • Such holding devices are suitable to exert a certain adjustable holding force on the conductor element.
  • by these holding devices triggered by a greater force than the holding force movement of the conductor element can be damped to a certain extent.
  • the person transfer device is connected to the other, e.g. arranged as an offshore wind turbine, object arranged.
  • This alternative has the advantage that each equipped with a person transfer device offshore wind turbine can accommodate employees of any ship, the ships are equipped by simple measures with a coupling element or the ships with a trained as a coupling element section on the fuselage, i. at the bow or at the stern, are to be provided.
