Definitions

  • the invention relates to a device for access to structural facilities at sea according to claim 1.
  • Such devices are used in structural facilities that are installed offshore, in the area of the sea at a defined height above the water level on foundation levels.
  • the foundation levels are supported on pillars; anchored in the seabed.
  • These facilities include wind turbines, control platforms for wind farms and oil rigs. All of these facilities require inspections, checks and repairs to be carried out more or less often. The delivery of materials and equipment as well as the access of personnel are therefore constantly required.
  • SWATH Small Waterplane Area Twin Hull
  • the invention has for its object to provide a device with which access to structural facilities of the type mentioned can be independent of all weather conditions, so that a supply of material, tools, food and staff is always possible.
  • the device according to the invention is designed in such a way that access to a structural device from a ship is possible at any time.
  • material, tools, food and personnel can be transported from a walk-in deck of a ship, regardless of the weather and all year round, to a building and can be picked up again.
  • the ship must be driven under that of the facility. This is always possible if the facilities of this type are built on foundation levels, which are installed at a defined height above the water level and are anchored in the seabed via three or four pillars that are sufficiently far apart.
  • the facility is equipped with a movably installed duct for this access. This is formed by a tube with a defined diameter.
  • the pipe is fully integrated in the device. This is particularly simple if the device is a wind turbine, in the tower of which the pipe forming the channel can be accommodated. In other devices that do not have a tower, an appropriate housing can be installed above the foundation level to accommodate such a pipe. If material, tools, food or personnel are to be brought to the facility, the canal is moved vertically downwards towards the ship with the aid of a drive device, to such an extent that the free end of the canal has a minimum distance A of 0.30 m to 0.50m from the accessible deck of the ship. This distance is kept constant.
  • the drive device is equipped with an electronic control unit, which is connected to several acoustic or optical distance sensors.
  • the sensors of the Distance sensors are preferably mounted externally on the channel, and zwar_sp. that they are aimed at the accessible deck of the ship. If the ship is raised or lowered due to high waves or if the distance between the deck and the channel changes for another reason, the minimum distance A is immediately adapted to the specified target value, which is stored in the controller unit.
  • the free end of the channel is closed at the bottom.
  • at least one outlet / inlet opening is provided in the lateral boundary wall of the channel, at a short distance from its closed end facing the water level, through which the interior of the channel is accessible. The outlet / inlet opening can be easily reached from the walkable deck of the ship since the minimum distance A between the ship's deck and the closed end of the canal is only 0.30m to 0.50m.
  • Two or more simultaneously running, sufficiently powerful and dynamically motorized cable winches can be used as the drive device for the channel, which are installed within the tower or housing and connected to the channel.
  • a hydraulic or pneumatic drive device can also be used.
  • a ring is attached to the outside of the channel above the outlet / inlet opening close to its closed lower end.
  • Hydraulic cylinders for example, engage the ring via joints.
  • the second ends of the hydraulic cylinders are also fastened via joints on the underside of the foundation level in the edge region thereof. These hydraulic cylinders are used to center the channel and to transmit forces to the channel.
  • Another hydraulic cylinder of the drive device acts on each of the first-mentioned hydraulic cylinders via a joint.
  • Each of these second hydraulic cylinders is fastened on the upper side of the foundation level via a joint to a support element which forms an angle of approximately 45 ° with the foundation level.
  • This drive device is also equipped with a controller unit which is connected to optical or acoustic distance sensors.
  • the channel can only be pushed into the building as far as the ring that surrounds it on the outside.
  • an additional elevator intended.
  • Such an elevator is installed in the building, and can. from there, always travel to the lower end of the channel, regardless of the position of the channel.
  • Such an elevator also makes sense if the drive device is formed by cable winches. If the building is a wind turbine, the elevator can be installed so that it can also be used to reach the nacelle of the wind turbine.
  • FIG. 2 shows a device that is equipped with an access device according to FIG. 1,
  • FIG. 4 shows the access device according to FIG. 1 with a hydraulic drive device.
  • the access device 1 shows an access device 1 with a channel 2, a drive device 3, a controller unit 4, distance sensors 5 and an elevator 6.
  • the access device 1 is installed in a structural device 10 shown in FIG. 2.
  • the device 10 is a wind turbine installed offshore in the area of the sea 11.
  • the access device 1 can also be integrated into any other structural device 10, provided that it is installed on a foundation level 12 at a defined height above the water level.
  • the foundation level 12 must also be anchored via pillars 13 in the seabed -14, as is the case with the tower 10T of the wind turbine 10.
  • the pillars 13 are arranged at such a distance that a for the transport of material, tools, Catering and personnel specific ship 15 can be driven between the pillars 13 under the foundation level 12, as shown in Fig. 2.
  • the channel 2 of the access device 1 is arranged entirely within the tower 10T of the wind turbine 10.
  • the channel 2 is formed by a cylindrical tube, the dimensions of which are selected so that there is still sufficient space inside the tower 10T in order to be able to move the channel 2 vertically up and down.
  • the channel 2 is dimensioned such that its downward-facing end 2A can always be arranged at a minimum distance A of 0.30 m to 0.50 m above the walkable deck of a ship 15, and its second end always remains within the tower 10T.
  • the inside diameter of the channel 2 is so large that the elevator 6 can be moved through it.
  • the channel 2 can be moved vertically downwards out of the tower 10T by means of the drive device 3, through a passage (not shown here) in the foundation level 12.
  • the drive device 3 in the exemplary embodiment shown here is two or more simultaneously running, sufficiently powerful and dynamic motorized cable winches 3S, which are installed within the tower 10T and connected to the channel 2.
  • a cylindrical component 20 is installed, which surrounds the channel 2 like a shell and serves as a guide element for the channel 2.
  • a sealing ring (not shown here) is arranged between the channel 2 and the guide element 20 in order to prevent the penetration of salty air and / or sea water into the interior of the tower 10T.
  • the downward end 2A of the channel 2 is closed.

They are connected to the controller unit 4 installed at the second end 2B of the channel 2, which always remains inside the tower 10T. The controller unit 4 is connected to the drive device 3. If the channel 2, as shown in FIG. 3, is moved out of the tower 10T in order to pick up or bring cargo from a ship 15, the distance between the channel 2 and the ship 15 is continuously determined with the aid of the distance sensors 5.
  • a storage space 21 is installed at the bottom end of the tower 10T, in which the loads delivered by the elevator 6 or the channel 2 can be temporarily stored. If the load is required directly in the nacelle 10G, it can be transported up to there with the aid of the elevator 6, provided that this is so far upwards within the tower 10T (not shown here).
  • FIG. 4 shows an access device 1 in which the channel 2 is moved with the aid of a hydraulic drive device 3.
  • a ring 22 is fastened on the outside at the first downward-facing end 2A of the channel 2, which tightly surrounds the channel 2.

Abstract

L'invention concerne un système permettant d'accéder à une installation (10) aménagée en mer (11) sur un plan de fondation (12) à une hauteur définie au-dessus du niveau de l'eau. Ce plan de fondation (12) est construit sur des piliers (13) qui sont ancrés dans le fond marin (14). Dans ce type d'installations (10), qui se présentent sous la forme d'éoliennes, de plateformes de contrôle d'installations de parc éolien ou de plateformes de forage, la livraison de matériaux et d'équipements et l'accès du personnel doivent être possibles à tout instant, ce qui est rendu particulièrement difficile en cas de conditions météorologiques défavorables. Ces difficultés peuvent être facilement surmontées à l'aide du système d'accès (1) selon l'invention, chaque installation (10) étant équipée d'un canal (2) installé de façon mobile. Pour permettre l'accès à l'installation (10), ce canal (2) peut être déplacé verticalement depuis celle-ci en direction de la mer (11). Une ouverture d'entrée/sortie (2Z) est positionnée à une distance minimale (A) d'un navire (15) se trouvant sous le plan de fondation (12), cette ouverture étant ménagée dans une périphérie latérale du canal (2) à proximité de l'extrémité (2A) dudit canal (2) qui est orientée vers le bas. L'extrémité inférieure du canal (2) est fermée et peut servir de surface de chargement. Le système selon l'invention comprend par ailleurs un ascenseur (6) pouvant se déplacer dans le canal (2) entre l'installation (10) et l'ouverture d'entrée/sortie (2Z). En l'absence de nécessité d'accès à l'installation (10), le canal (2) est placé à l'intérieur de l'installation (10) ou dans une structure installée sur le plan de fondation (12).
