Definitions

  • the object of the invention is related to access to the towers of offshore wind turbines. Specifically it is a crane that picks up persons and cargo from a vessel and carries them to the tower and vice versa.
  • the main characteristic is that the aforementioned crane is commanded by remote control and has a control system for monitoring the swell, mainly the wave's height and period.
  • the system that enables the transfer from the vessel to the wind turbine and from the wind turbine to the vessel is complicated even further in the event of having to rescue a helpless injured person.
  • the main advantage provided by the crane which is the object of the invention is that this crane is valid for any user and requires no prior knowledge, and it,can also be used by injured or unwell persons who have no mobility at the time of being evacuated.
  • One object of the invention is to have a crane on the base of the tower of an offshore wind turbine.
  • Said crane is operated by remote control and Is usually commanded from a vessel.
  • it can adapt to the swell.
  • the most usual swell In deep sites is due to the ground swell: long waves very regular over time.
  • the wind swell results in smaller, more frequent waves.
  • the crane's control is adapted mainly to the ground swell (long-period waves).
  • Another object of the invention is for the system to include a visual aid display showing precise data on the height at which the crane hook is located, the wave height and amplitude, whether the hook is being raised or lowered, and other similar data.
  • Another object of the invention is for the crane arm to be sufficiently long so that it can be positioned properly over the vessel's platform (usually on the bow) so as not to require the skipper to get too close to the wind turbine tower.
  • the crane has an independent energy source so that it can be used in situations where neither the grid nor the wind turbine provide electricity.
  • the crane arm has a joint to enable the hook to be retracted over the platform located on the base of the tower and from which the persons and objects are hoisted and moved.
  • an offshore wind turbine is supported on a transition part (2) that juts out above the waterline (1).
  • a platform (3) is arranged from which the tower (4) itself emerges.
  • the wind turbine (not shown in the figure) is placed on top. Access needs to be provided to the platform (3), as this is the place from which the tower (4) and consequently the inside of the wind turbine are accessed.
  • the operators travel by boat (5) to the base of the wind turbine. Once there, the vessel's bow (5) is kept tightly against the transition part (2) and specifically against two vertical supports (6) that prevent possible damage to both surfaces due to friction.
  • FIG. 2 shows a crane (8) located on the platform (3) existing at the base of a wind turbine.
  • the crane (8) has an arm (9) along which a cable (11) with an end hook (10) passes through. This hook (10) will be raised or lowered depending on whether the motor's operation winds (not represented) or unwinds the cable.
  • the crane (8) control and operation is done from the vessel (5) by remote control.
  • a control monitor (12) displays at all times information related to the swell (period and height) and other data needed for the crane (8) to be able to automatically superimpose the swell profile (1) on the hoisting/descent profile of the crane (8) itself.
  • Sensors on the system on board are used to obtain information on the ground swell at a given point.
  • the vessel can be fitted with accelerometers on the bow to obtain the period and height of the wave and/or the movement of the vessel itself.
  • a sample graph is provided with the X-axis representing the periods separated into 10-second groups (time) and the Y-axis representing the wave's peak-valley height (height).
  • the embodiment shown includes a drawing representing the crane (8) and another one for the vessel (5).
  • the wave's peak-valley height is 5 meters and it is represented using a dotted-line sine wave (18).
  • the cable (not represented) of the crane (8) starts being lowered linearly from the initial 10 meters and its descent is represented by a solid line (19). Once the information on the wave's height and period and/or the vessel's movement has been entered, the cable (not represented) starts adjusting its linear descent until it is superimposed (20) on the wave's height and period sine shape. This enables the persons to be transferred without being knocked when going on board.
  • Figure 5 shows the unit made up of the tower (4), the platform (3) and the crane (8) as seen from above.
  • the arm (9) of the crane (8) extends from the platform until it is located above the deck of the vessel (5).
  • the length of the arm (9) can vary between 15 and 20 meters.
  • This arm (9) is articulated (21) and according to the preferential embodiment it can be bent while maintaining the horizontal plane. In this way, by combining the articulated movement of the arm with the circular movement of the crane (8), the tip of the arm (9) can be located above the platform (3).
  • the vessel can also be equipped with a dynamic positioning system. Once certain coordinates have been entered the vessel remains stationary, automatically operating the propellers and rudders, without navigator intervention.
