- the ballast medium conveying arrangement can be arranged in or on the foundation. A change in the fill level and/or the overall density changes, in particular, the said vertical distance.
- a target height can be a target filling quantity (eg full, half full, empty, x liters, etc.).
- the ballast medium conveying arrangement can change the fill level and/or the overall density of the ballast tank in accordance with a predetermined height setpoint of this type in order to change the said vertical distance.

- a weight force (corresponding to the weight of the weight element of the weight arrangement) is exerted on the foundation by the at least one weight element of the weight arrangement.
- a change in said vertical distance can be brought about by an adjustment between said states.
- the offshore wind power plant can, alternatively or additionally, comprise at least one winch device coupled to at least one anchor connection.
- the winch device can be set up to change the length of the anchor connection between the anchor and the buoyant foundation, that is to say in particular to shorten or lengthen it in accordance with a desired height value.
- the winch device comprises a substantially cylindrical and rotatable drum.
- coupled means in particular that the at least one anchor connection in the form of an anchor cable or an anchor chain can be wound up and unwound on the drum (in particular between a minimum and maximum length).
- One end of the anchor connection can hereby be firmly attached to the drum or another attachment point of the winch device.
- the winch device can preferably include at least one controllable and motor-based drive, in particular an electric motor that can be supplied with electrical energy from the offshore structure.
- the drive can be controlled by the control module in such a way that the length is changed in such a way that the (instantaneous and/or predicted future) height or the vertical distance corresponds (essentially) to the at least one desired height parameter or is at least in the permissible position range .
- the winch device can comprise at least one parking brake.
- the parking brake may be releasable (and lockable once changed) to change the length of the anchor linkage. If the length of the anchor connection is to be changed, the control module can, for example, activate the parking brake so that it is released. The length of the anchor connection can then be changed, in particular by the drive, as has been described. The parking brake can then be locked (again) either automatically or by being activated again, e.g. by the control module. The load on the drive can be reduced as a result.
- the vertical spacing can be changed accordingly. It will be appreciated that when a winch facility is used, it may be necessary to tie an anchor deeper into the underwater bed and/or to increase the weight of the anchor (compared to the case where no winch facility is provided).
- the offshore wind farm includes a plurality of offshore wind turbines described above.
- the offshore wind farm includes at least one height control device, set up to control at least one first height adjustment device of an offshore wind power plant with a desired height value for effecting a change in a vertical distance of a buoyant Foundation of the offshore wind turbine to the underwater ground surface according to the altitude target value, wherein the altitude target value depends at least on the at least one meteorological environmental condition of the offshore wind turbine (this is associated in particular, as previously described).
- a (central) height control device e.g. implemented as a software module in a central control device of the offshore wind farm
- the plurality of offshore wind power plants can be controlled via a communication network, for example by transmitting at least one control command containing at least one (previously described) nominal height value.
- the height setpoint can also depend on the position of a first offshore wind power plant in relation to at least one other offshore wind power plant of the offshore wind farm. In other words, a height setpoint then has to be position-dependent.
- the height setpoint used when controlling a specific offshore wind power plant can depend on the position of this offshore wind power plant within the offshore wind farm.
- each offshore wind turbine can be assigned a park position attribute (e.g., a geographic indication of the offshore wind turbine, an indication of which row the offshore wind turbine is located in with respect to a particular direction (e.g., prevailing wind direction), and/or the like).
- park position attribute (indicating a park position) may be stored in a data storage device accessible by the height control device.
- the electrical energy yield can be reduced when an offshore wind power plant is in the lee of another offshore wind power plant under certain meteorological environmental conditions.
- the energy yield can be further increased by taking into account the respective parked position of an offshore wind power plant in accordance with the application. For example, different vertical distances and thus hub heights can be set for two offshore wind turbines arranged one behind the other (seen in the current or predicted main wind direction). As a result, the total yield of these two offshore wind turbines can be increased.
- At least a first meteorological environmental condition and a second meteorological environmental condition that differs from the first environmental condition can be specified (as has already been described above).
- the height control device can be set up to control the plurality of offshore wind turbines with first height setpoints according to a first predetermined height adjustment rule assigned to the first meteorological environmental condition upon detection that the first meteorological environmental condition is met by the specific meteorological environmental parameter, as described above.
- the (at least one) altitude adjustment rule e.g. stored in the data storage arrangement mentioned
- the first desired height values can each differ from one another, for example—as explained above—depend on the respective parked position of the respective offshore wind turbine.
- the altitude control device can be set up to control the plurality of offshore wind turbines with second altitude setpoints, which at least partially differ from the first altitude setpoints, in accordance with a second predefined altitude setting rule assigned to the second meteorological environmental condition when it is detected that the second meteorological environmental condition is caused by the specific meteorological environmental parameters are met.
- This can be done in a manner analogous to the previously described control with first desired height values.
