Definitions

• the invention relates to a lifting device for the assembly and service of an underwater power plant with a turbine generator unit which can be placed on a support structure.
• Submersible underwater power plants for generating energy from a sea current, in particular a tidal current, are known.
• a turbine generator unit attached to a support structure is circulated freely without an additional dam structure.
• the water turbine may be formed rotor-shaped and rotate on a nacelle, in which the generator components and the drive train are added.
• a disadvantage of the use of a cable guide is that initially the guide cable has to be pulled starting from a watercraft used for the installation to the support structure and fastened thereto. This installation step is usually carried out by divers and is therefore complex and dangerous.
• Another disadvantage is that the guide cables are removed after the initial installation of the underwater power plant to safely prevent a winding of the guide cables in the water turbine during operation.
• a salvage of the turbine-generator unit to perform a plant inspection over water then there is the need to realize a linkage for a crane system on the turbine-generator unit and a lateral well guided and centered vertical movement for lifting the turbine-generator unit from the Perform coupling device.
• service divers are again active for hooking in the crane hook or for attaching straps and for attaching guide ropes, which, in addition to the high risk of accidents, makes an installation service more expensive.
• the invention has for its object to provide a lifting device, which makes it possible to set up a turbine generator unit of an underwater power plant on an associated support structure for installation and for the maintenance of an already installed system to lift the turbine-generator unit from the support structure and on deck of a watercraft to recover. It is desirable with a lifting device both the initial installation and the To execute plant service. Further, a method is sought, which allows a safe placement of a turbine-generator unit on a support structure and a subsequent lifting of this unit to above the water level.
• the device or the method should be characterized by a high handling security of the turbine-generator unit and allow such a degree of automation that can be largely dispensed with the use of service divers. Furthermore, rapid installation and recovery of the turbine-generator unit is required since the low-flow time window is typically small. Furthermore, the device or the method should be distinguished by a universal use for different underwater power plants with similar size dimensions, which are designed differently in detail.
• a lifting device comprises a diving component, which is lowered from a ship's crane to the installation site of the underwater power plant.

• a centering takes place in two mutually perpendicular directions transverse to the vertical axis.
• the laterally secured and centered, diving component can then be brought to such a depth, that by means of a movable clamping element of the gripping device, the turbine generator unit can be included for securing. If for this purpose at least two forceps jaws acting against each other are used for the clamping element, which can carry the entire weight of the turbine generator unit, this can be lifted out of the coupling device of the support structure by means of a crane system connected to the diving component.

Further, after the coupling of the dipping component to the turbine-generator unit, the guide cables are tightened and brought into a vertical position suitable for lifting.
• the attachment of the guide cable to the support structure is permanently retained, wherein the unattached end of the guide cable is led away from the plant so far that wrapping in the turbine during plant operation is safely excluded.
• the loose end of the guide rope can be stored with aconcentrsbeatung on the seabed.
• an automatically releasable buoyancy device may be in communication with the free end of the rope.
• the closing movement of the movable surrounding elements of the transverse centering device and the closing of the movable clamping elements of the gripping device take place from a position above the turbine generator unit.
• the diving component is in turn brought into the area of the underwater power plant, above the turbine generator unit. Then the enclosing elements surround by a from above outgoing pivotal movement of the support structure and ensure at least the lateral centering of the diving component.
• the setting of the vertical distance to the turbine-generator unit by the closing of the Um can be adjusted.
