Definitions

  • the invention relates to wind turbines
  • Offshore wind turbines are previously known in the art.
  • One type of prior art wind turbine is permanently mounted to the seabed. Turbines of this type are designed for shallow water, typically at a depth of 50 m or less.
  • Another type of wind turbine known in the art is the floating wind turbine. Turbines of this type generally comprise a windmill generator unit mounted atop an elongated shaft. The buoyancy necessary to keep the turbine afloat is provided by buoyancy chambers contained in the shaft.
  • Offshore wind turbines of this type are extremely large and cumbersome constructions. The mounting and anchoring of the turbine is a particularly complex operation. This makes the retrieval of the turbine for maintenance and repair a time consuming and expensive operation, since the entire structure must be retrieved and transported to the maintenance site.
  • the present invention overcomes the disadvantage with known offshore wind turbines by providing a wind turbine comprising a docking station arranged at an offshore location.
  • An elongated shaft to which is mounted a windmill generator unit is removably attachable to the docking station. All of the necessary power and utility cables are connected to the docking station, which may be permanently anchored or otherwise stationed at a desired location.
  • the elongated shaft may be disconnected from the docking station, such that the shaft and windmill generator unit can be transported to the repair facility while the docking station remains anchored in place.
  • the term "offshore" should be understood to apply to use in connection with any type of body of water.
  • Fig 1 is a perspective view of a preferred embodiment of the invention
  • Fig 2 is a perspective view of the docking station
  • Fig 3 is a perspective view of the docking station, showing internal structures
  • Fig 4 is a perspective view of connection unit attached to the elongated mast of a turbine
  • Fig 5 is a perspective view of a bolt arrangement
  • Fig 6 is a perspective view of an alternative embodiment of the docking station
  • the offshore wind turbine comprises a vertical turbine unit 20 which may be removably attached to a docking station 22.
  • Turbine unit 22 comprises a windmill generator unit 24 mounted atop an elongated shaft 26.
  • docking station 22 is a buoyant body that floats on the surface of the water, as shown in Fig 2. Docking station 22 according to this embodiment is held in place at a desired location by a plurality of anchor lines 28.
  • docking station 22 is a hollow body having one or more air-filled buoyancy chambers 30, as shown in Fig 3.
  • the chambers may be partially filled with a ballast material in order to increase the stability of the docking station.
  • One or more of chambers 30 may house control units.
  • Cables 32 such as power and/or utility cables from the shore, are connected to docking station 22 at an appropriate termination interface.
  • the cables 32 are connected to docking station 22 by passing through a conduit 34, which may be a flexible bend restrictor device or a rigid conduit. The cables pass to a "manhole" access member 35 on the upper surface of the docking station.
  • elongated shaft 26 comprises one or more compartments at its lower end.
  • a first compartment 36 contains a ballast material in order to provide vertical stability to the mast, whereas one or more buoyancy compartments 38 provide buoyancy to the turbine unit.
  • Sea water may be selectively pumped into or out of buoyancy compartments 38 in order to regulate the buoyancy, and thereby the vertical position of mast 26 in relation to the surface of the water.
  • turbine unit 20 further comprises a connection unit 40 arranged on elongated shaft 26.
  • connection unit 40 may be a hollow body comprising one or more buoyancy chambers 42.
  • buoyancy compartments 38 water may be pumped into or out of buoyancy chambers 42 in order to regulate the buoyancy of turbine unit 20.
  • the buoyancy of turbine unit 20 can be provided either by buoyancy compartments 38 alone, buoyancy chambers 42 alone, or any combination thereof.
  • a pump unit 39 for pumping seawater into and out of compartments 38 and/or chambers 42 may be arranged in one of chambers 42 as illustrated in Fig 4.
  • connection unit 40 further comprises a connection member 44, arranged for cooperative engagement with a corresponding connection interface 46 of docking station 22 as shown in Fig 3.
  • connection member 44 is a raised structure comprising a plurality of teeth 48. Teeth 48 are arranged to fit into and engage corresponding slots 50 arranged on the inside walls of a U-shaped receiving opening 52 in docking station 22. The inside walls of receiving opening 52 have guide surfaces 54 that corresponding to guide surfaces 56 of the raised portion of connection member 44.
  • turbine units 20 is towed or otherwise transported to the location where docking station 22 is anchored.
  • turbine unit 20 is towed in the vertical orientation with connection unit 40 partially submerged beneath the surface of the water at a lower depth than docking station 22.
  • Turbine unit 20 is manoeuvred into position such that elongated shaft 26 is received in receiving opening 52, with connection member 44 in vertical alignment with connection interface 46. Water is thereafter pumped out of buoyancy chambers 42 and/or buoyancy compartments 38 such that turbine unit 20 rises into engagement with the docking station.
  • the teeth 48 of connection member 44 engage with the slots 50 of connection interface 46.
  • the connection operation is assisted by mutual cooperation of guide surfaces 54 and 56.
  • connection unit 40 As shown in Fig 4, a plurality of guide pins 58 are provided on the upper surface of connection unit 40 that engage guide recesses 60 on the lower surface of docking station 22.
  • the updrift of turbine unit 20 insures a secure connection between connection member 44 and connection interface 46.
  • connection unit 40 is attached to the docking station 22 by passing a plurality of locking bolts 62 through the bolt locking holes 64, into engagement with slots 65 on the upper surface of connection unit 40.
  • the engaging end of the locking bolts are "T" shaped as shown in Fig 5, and are turned into locking position hydrauslically. Power and utility cables can are connected from manhole 35 on the docking station to a similar manhole on the turbine unit as illustrated in figures 1, 3 and 4.
  • connection unit 40 may have a cylindrical recess 67 for receiving conduit 34.
  • sensor units are provided in order to monitor successful connection of turbine unit 20 to docking station 22.
  • the sensors may be pressure sensitive sensors 66 located adjacent slots 65 as shown in fig 4. Sensors 66 monitor the correct positioning of the bolt holes and slots prior to hydraulic activation of the bolts.
  • Other sensors may be arranged as part of connection member 44 to monitor the connection with connection interface 46, or to monitor stresses in the connection.
  • Docking station 22 and turbine unit 20 may also be equipped with GPS position monitoring devices to monitor and guide the connection operation.
  • connection member 44 thus disengages from connection interface 46, and connection unit 40 sinks below the docking station. Shaft 26 may be thereafter manoeuvred out of receiving opening 52 and towed back to shore.
  • Figure 6 shows an alternative arrangement of the docking station whereby buoyancy is provided by a horseshoe shaped ballast ring 68.
  • While the preferred embodiment provides for the turbine unit being raised into engagement from underneath the docking station, it is also possible to arrange the components such that the turbine unit is lower into engagement with the docking station from above. In such an embodiment it would be possible to arrange the docking station submerged in the vicinity of the seabed, particularly in areas of shallow water
