The invention is based on a platform device with at least one buoyant platform, which is intended to carry at least one energy-generating unit at least partially above a water level.

It is proposed that the platform has at least one outer edge region with at least one wave absorption element, which is intended to reduce a wave effect within the outer edge region to a defined value. By the wave absorption element, a region, such as the outer edge region, can be provided on a sea in which there is a smaller wave effect compared to the open sea. This can provide a safe stand for the power generation units on the sea, which allows the sea location with its advantages, such as the huge usable areas, can be used for energy. The platform device can thus create new possibilities for obtaining regenerative energy. The use of sea surfaces can facilitate the obtaining of a permit for the construction of power generation units which, in particular, give rise to aesthetic and conservation concerns, allowing for easy power generation. The term "provided" should be understood to mean in particular specially equipped and / or designed. "In this context, the term" carry over a water level "should be understood to mean that the energy production unit is at least partially held above the water level by the platform. Under a "wave effect" should in particular, a change caused by a swell a support surface of the platform and thus a change in a position of the power generation units are understood. Advantageously, the platform with the support surface covers a seawater surface. The platform advantageously covers a seawater surface of at least 1 square kilometer, more preferably at least 2 square kilometers and most preferably more than 5 square kilometers. Preferably, the wave absorption element has a diameter of at least 60 centimeters, advantageously of at least 80 centimeters and most preferably between 90 and 100 centimeters.

The at least one wave absorption element preferably reduces the wave effect in the direction of a geometric center of the platform. Advantageously, the at least one wave absorption element reduces the wave action in that direction to the defined value which is less than 80% of a wave output, more preferably less than 60% of the wave output, and most preferably less than 30% of the wave output. A "wave output effect" should in particular be understood to mean a wave effect which is present before impinging on the platform, that is to say on a multi-sided outer edge of the platform. <br/><br/> Preferably, a "wave effect" shall be understood to mean a wave effect which arises from a wave height of at least one meter That is, a wave with a wave height of 1 meter is preferably reduced to at most 80 centimeters wave height, 60 centimeters wave height or 30 centimeters wave height .. Advantageously, the outer edge surrounds the platform and thus encloses the covered Sea water surface. A length of the outer edge along one side is advantageously at least one kilometer, more preferably at least two kilometers and most preferably more than three kilometers.

It is further proposed that the outer edge region has a radial extension of at least 50 meters and the wave absorption element is provided to reduce the wave action over the radial extent of the outer edge region to the defined value. As a result, a particularly advantageous outer edge region can be achieved. A "radial extension" is to be understood in particular an extension which extends from the sea-side outer edge of the platform in the direction of the geometric center of the platform.

In an advantageous embodiment, the platform has at least one central region, which has a defined radial distance from an outer edge and in which the shaft effect is at least substantially eliminated. As a result, a particularly advantageous platform or a particularly advantageous range can be achieved. In this context, the term "substantially" should in particular be understood to mean that the wave effect in the central region is less than 30% of the output effect of the shaft Distance that runs from the multi-sided outer edge of the platform in the direction of the geomet- rischen center of the platform. Preferably, the central region is surrounded by the outer edge region and lies between the outer edge area and the open sea. Advantageously, the defined radial distance is between 300 and 700 meters, wherein the radial distance is particularly advantageously at least 500 meters. Preferably, the central area has an area of at least one square meter.

Particularly preferably, the wave absorption element is elastic. As a result, a flexibility and thus an adaptation to a changing seawater surface without the arrangement of joints can be realized, whereby wear of the platform can be reduced. Preferably, the elastically formed wave absorption element reduces the wave effect by receiving a wave energy. The wave absorption element thereby advantageously reduces the swell. In particular, the entire platform can thereby be formed without joints.

In a preferred embodiment, the platform has at least one at least substantially horizontally arranged wave breaking element, which is intended to reduce a swell. As a result, the wave effect can be reduced particularly advantageously. A "wave breaking element" is to be understood as meaning, in particular, an element that reduces the wave energy by breaking the wave and thus converting it into turbulence Preferably, the wave breaking elements are arranged above and / or below the water level Advantageously, the wave breaking element is a sheet metal and particularly advantageous In this context, the term "horizontal" is to be understood in particular to mean that a main extension plane is formed as a trapezoidal sheet. surface of the breakwater element runs parallel to the water level. By "at least substantially" in this context is meant in particular a deviation of at most 10 degrees from a horizontal arrangement.

It is further proposed that the wave absorption element has a main extension direction, which is aligned substantially parallel to the water level. As a result, the wave energy can be reduced particularly efficiently. Preferably, the wave absorption element is tubular.

It is also proposed that the platform has at least one further wave absorption element, wherein the at least two wave absorption elements are arranged substantially parallel to one another. As a result, the wave effect can be reduced by a larger, covered by the platform seawater surface.

As a result, a particularly advantageous connection of the wave absorption elements can be achieved. Preferably, the defined distance is smaller than an axial extent of the wave absorption elements in the main extension. direction. The connection unit preferably connects the two wave absorption elements in parallel next to one another. Advantageously, the defined distance of the wave absorption elements is greater than one meter.

Particularly preferably, the wave absorption element is at least partially formed as a buoyancy element. As a result, it is particularly advantageous to provide a lift for carrying the at least one energy-generating unit.

Furthermore, it is advantageous if the platform device has a payload carried by the at least one wave absorption element, which is intended to effect a displacement of the wave absorption element of at least 75%. As a result, the wave effect can be reduced particularly efficiently. By "effected displacement" is meant in particular a volume of water displaced by the wave absorption element with respect to an entire volume of the wave absorption element.

Furthermore, it is advantageous if the platform device has at least one wind turbine and / or at least one

Photovoltaic system has. As a result, a complementary energy generation can be realized, whereby a continuous Liehe energy production can be achieved. An arrangement of wind turbines and / or photovoltaic systems on the platform in the open sea can increase the efficiency of the wind turbines and / or the photovoltaic systems, since there are hardly any obstacles on the open sea, which slow down the wind or cast shadows.

Advantageously, the platform device can also have at least one solar thermal system. The platform device preferably has a plurality of photovoltaic systems and / or a plurality of wind power stations, which form a photovoltaic power plant and / or a wind power plant. Preferably, the at least one power generation unit is formed by the wind turbine or by the photovoltaic system.

In a further embodiment according to the invention, it is proposed that the platform device has at least one buoyancy element independent of the shaft absorption element, which is intended to carry at least one independent payload. This allows an additional load to be placed on the platform device. An "independent buoyancy element" should be understood to mean, in particular, a buoyancy element that provides additional buoyancy independently of the wave absorption elements.The independent buoyancy element is preferably balanced with respect to the wave absorption element, ie the buoyancy element autonomously and completely absorbs the independent payload It is advantageous if the platform device has at least one energy storage and / or energy conversion unit which is provided to store and / or convert energy generated by the at least one energy production unit may be preferred. The energy conversion unit gains or generates hydrogen. Advantageously, the energy storage unit is designed as a hydrogen storage container for storing the hydrogen. In principle, the energy storage unit can also be designed as a battery unit.

In principle, the energy generated by the platform device can also be stored or converted externally. In particular, storage of the electrical energy generated by the platform device as a potential energy or a positional energy is advantageous. The storage of energy is preferably carried out in a reservoir, such as in a reservoir in Switzerland. Advantageously, an emptying of the reservoir and a filling of the reservoir takes place independently of each other, wherein the filling of the reservoir is realized with the energy generated by the platform device. Preferably, the emptying of the reservoir is based on energy requirements and the filling of the reservoir for energy supply. In particular, the emptying and the filling of the reservoir take place simultaneously or simultaneously.

In principle, it is conceivable that the at least one wave absorption element has at least one cavity which is provided for receiving hydrogen. As a result, a particularly simple energy storage unit can be realized. Preferably, the cavity of the wave absorption element is at least partially formed as the hydrogen storage container. For the embodiment as a hydrogen storage container, the wave absorption element is advantageously coated with a hydrogen-impermeable layer. It is also proposed that the platform device has at least one attachment and / or deflection unit which is provided to fasten the platform and / or to rotate about an axis of rotation. As a result, an efficiency of at least one photovoltaic system can be increased. In principle, the fastening unit and the deflecting unit can be designed separately or it is possible to dispense with a deflecting unit. Preferably, the rotation of the platform is limited to an angular range.

In a further embodiment according to the invention, the wave absorption element is arranged at a defined depth below the water level. As a result, a further simple embodiment of a wave absorption element can be realized. Advantageously, the wave absorption element disposed below the water level at least partially decouples the platform from the swell, thereby reducing the wave effect on the platform. A "defined depth" is to be understood as meaning, in particular, an average distance, resulting from the payload, between a longitudinal axis of the wave absorption element and the water level.

Furthermore, it is advantageous if the platform has at least two platform modules. This makes the platform particularly easy to assemble and / or manufacture. Preferably, a size of the platform through the platform modules at least partially arbitrary. Advantageously, a platform module has a plurality of wave absorption elements welded together along the main extension direction. Preferably, the welded together Wave absorption elements arranged in parallel to another welded together wave absorption elements.

In addition, a method for producing the platform device is proposed in which the wave absorption element is extruded directly into the sea. As a result, a transport of the wave absorption elements can be realized particularly easily. In particular, this can produce wave absorption elements with the greatest possible axial length, without paying attention to possible transport problems or space requirements. The wave absorption elements preferably pass through a cooling unit and / or a processing unit before they enter the sea. In particular, "direct" is to be understood as meaning that an extrusion movement is used to push the wave absorption element into the sea, Preferably at least part of the wave absorption element is located in seawater during an extrusion process or an extrusion movement Land supported and / or a mounting or processing of the wave absorption element take place on land Advantageously, the wave absorption element is guided in the extrusion process into the sea water, without storage on land.

FIGS. 1 to 18 show an exemplary embodiment of a platform device according to the invention. In FIG. 1, the entire platform device is shown schematically in a plan view. The platform device is disposed on a sea 70a. It is anchored at a distance of more than 70 km from a coast 72a on the sea 70a. The platform device has a square shape in this exemplary embodiment. It generates regenerative energy. The platform device is designed as an anchored raft.

For supply and disposal and thus for maintenance, the platform device comprises a channel 74a, a channel 74a 'and a surface 76a. The channel 74a, the channel 74a 'and the surface 76a share the platform device. The channel 74a, the channel 74a 'and the surface 76a are realized by a cleared seawater surface within the platform device. The surface 76a is disposed in a central region 36a offset from a geometric center of the platform device. The channel 74a and the channel 74a 'each extend from an outer edge 40a of the platform device to the surface 76a, with the channels 74a, 74a' disposed opposite each other with respect to the surface 76a. The two channels 74a, 74a 'are designed as access routes for watercraft. Thus, the watercraft can reach the surface 76a from two opposite sides. In this embodiment, the channel 74a and the channel 74a 'each have a width of 48 m. The surface 76a has a width and a length of about 360 m each. To dock the watercraft, the platform device has two landing quays. The landing quays are arranged in the surface 76a. The two landing quays are arranged opposite each other. Further, the platform device includes personnel accommodations, a convention center, a communication tower, a heliport, and a sea water. The seawater cable is provided for transmission of elekt-electric power to a transfer station on the coast 72a. The sea water cable runs under a Wasserpie gel 22a.

The platform device has two types of power generation units. The two types of power generation units are partially complementary to each other, i. the two types of power generation units are partially complementary The first type of power generation units is through

Photovoltaic systems trained. The second type of power generation units is formed by wind turbines. In FIG. 1, the energy generating units formed by photovoltaic systems are shown as boxes 78a. In FIG. 1, the energy generating units formed by wind power plants are represented by a symbol 80a.

As a rule, there is essentially no wind in sunshine and thus cloud-free sky and thus generates the first type of power generation unit energy and under overcast sky and thus substantially lacking sunshine, the second power generation unit generates energy, the platform device generates regenerative in the rule continuously Energy. The energy production units formed by photovoltaic systems and those generated by Power generating units formed energy generating units are thus complementary to each other.

For carrying a plurality of power generation units formed by photovoltaic power plants above the water level 22a of the

Sea 70a, the platform device comprises a buoyant platform 10a. The platform 10a has a plurality of platform modules. The platform modules are interconnected. The interconnected platform modules form the uniform, inherently homogeneous platform 10a.

The platform 10a covers a defined seawater surface. The platform 10a also has the outer edge 40a. The channel 74a, the channel 74a 'and the surface 76a are arranged as the reserved seawater surfaces within the platform 10a, with the channels 74a, 74a' and the surface 76a sharing the platform 10a. The platform 10a has walk-in areas, which are provided in particular for maintenance and care of the power generation units.

The platform 10a has an outer edge portion 24a, an intermediate portion 82a and the central portion 36a (see Fig. 14). The outer edge region 24a surrounds the intermediate region 82a and the central region 36a. The outer edge region 24a is located on the sea side on the platform 10a. The outer edge region 24a is bounded by the outer edge 40a on the sea side. The outer edge 40a surrounds the outer edge region 24a. The intermediate region 82a is located between the outer edge region 24a and the central region 36a on the platform 10a. The intermediate region 82a delimits the outer edge region 24a in the direction of Platform 10a geometric center. The intermediate region 82a delimits the central region 36a.

The outer edge region 24a has a radial extension 34a. The outer edge portion 24a is defined by the radial extent 34a. The radial extent 34a extends from the outer edge 40a in the direction of the geometric center of the platform 10a and the central portion 36a. The geometric center of the platform 10a corresponds to the geometric center of the platform device. The central region 36a has a defined distance 36a from the outer edge 40a.

A platform surface of the interconnected platform modules and a number of interconnected platform modules are basically variable. In this embodiment, the platform modules each have a length of about 120 m and a width of about 36 m. In particular in the area of the surface 76a and in the region along the channels 74a, 74a ', the length and the width of the platform modules may differ. The platform 10a has a length and a width of 3400 meters in this embodiment. The seawater surface covered by platform 10a is thus about 11.56 km ² . The platform 10a thus has about 2600 interconnected platform modules.

To reduce or reduce a wave effect, the platform 10a has a plurality of wave absorption elements. Within the outer edge region 24a, the wave absorption elements reduce the wave effect to a defined value. They reduce the wave effect in the direction of the geometric center of the platform 10a or in the direction of the geomet- center of the platform device. The radial extent 34a of the outer edge region 24a is 50 meters. The wave absorption elements reduce the wave action over the radial extent 34a of the outer edge region 24a to the defined value.

The wave absorption elements substantially lift up the wave action in the central region 36a. After the defined radial distance 38a, starting from the outer edge 40a of the platform 10a in the direction of the geometric center of the platform 10a, the wave absorption elements set a swell quiet area of the platform 10a. The surface 76a thus has substantially no swell compared to the outer edge 40a of the platform 10a. The surface 76a is formed as a still water surface. The defined radial distance from the outer edge 40a is approximately 500 meters.

All wave absorption elements of the platform 10a are formed analogously. For the sake of clarity, only the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a,

268a (see Figures 2 to 10). The wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a each have a main extension direction 42a, which is aligned substantially parallel to the water level 22a. The wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a are each formed as elongate wave absorption elements. To form the platform 10a, the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a are interconnected along their main extension direction 42a and along a direction perpendicular to the main extension direction 42a and parallel to the water surface 22a. Along her Main extension direction 42a, the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a are arranged directly behind one another. Along the direction perpendicular to the main extension direction 42a and parallel to the water level 22a direction 84a, the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a are spaced adjacent to each other.

The directly behind one another connected wave absorption elements are arranged parallel to the other directly behind the other connected wave absorption elements. All wave absorption elements of the platform 10a are thus arranged linearly. In principle, however, another arrangement which appears expedient to the person skilled in the art, such as, for example, a checkered arrangement or a checkered arrangement in alternation, is also possible.

The wave absorption elements which are separated from the channels 74a, 74a 'are interconnected by a connection that crosses the channels 74a, 74a' below the water level 22a or above the water level 22a. This connection has a distance from the water level 22a, so that larger vessels can use the channels 74a, 74a '. The wave absorption element 26a and the wave absorption element 28a are shown in FIGS. 2 to 8. The wave absorption element 26a is tubular. It is elastic. It is designed as an elastic tube with a cavity. The wave absorbing member 26a reduces the wave effect by reducing a swell. The wave absorption element 26a is Seawater resistant and UV resistant. The wave absorption element 26a is made of polyethylene. The wave absorption element 26a has a diameter of 90 cm, a wall thickness of 2 cm and an axial extent in the main extension direction 42a of 20 meters.

All wave absorption elements of the platform 10a are formed analogously to the wave absorption element 26a. In this exemplary embodiment, a platform module 24 has wave absorption elements. Each six wave absorption elements are welded together along their main extension direction 42a, thereby defining the length of the platform module of about 120 m. The wave absorption elements are arranged in four rows, whereby they define the width of the platform module of about 36 m. One row corresponds to the six wave-absorbing elements welded together. The six wave-absorbing elements welded together are arranged in parallel to the other six wave-absorbing elements welded together.

In order to prevent the wave absorption element 268a from being flooded or vice versa in the event of leakage of the wave absorption element 28a, the wave absorption elements 28a, 268a are separated along their main extension direction 42a by a bulkhead element 270a (see Fig. 2). The wave absorption elements 28a, 268a are welded together via the bulkhead element 270a. The bulkhead member 270a is disposed within cavities of the wave absorbing members 28a, 268a. The bulkhead element 207a separates the cavities of the wave absorption elements 28a, 268a fluidically from each other. The bulkhead element 270a is designed as an inner tube, the outer diameter of which corresponds to an inner diameter of the wave absorption elements 28a, 268a. One side 272a of the bulkhead member 270a is welded. One side 274a of the bulkhead member 270a is open in this embodiment. The bulkhead member 270a is also elastic. In principle, the bulkhead element can also be formed by a solid material. For welding the bulkhead element 270a with the wave absorption element 28a and the wave absorption element 268a and thus for welding the wave absorption elements 28a, 268a, a heating wire 276a is arranged respectively on the sides 272a, 274a of the bulkhead element 270a. The bulkhead element 270a is welded from the inside by the heating wire 276a to the wave absorption element 268a and by the heating wire 278a to the wave absorption element 28a.

All Wellenabsorpti- onselemente of the platform 10a arranged directly behind one another are analogous along their

 Main extension direction 42a welded together. All bulkhead elements are formed analogously to the bulkhead element 270a. Flooding of all successively arranged wave absorption elements in the event of leakage of individual wave absorption elements is thereby prevented.

In this embodiment, the cavities of the wave absorption elements are thus each fluidically separated from each other after 20 m. Basically, a separation of the cavities through the bulkhead elements also take place after a different distance, depending on how large the axial Er- Extension of the wave absorption elements, wherein the axial extent of the wave absorption elements is preferably greater than 5 meters and more preferably greater than 10 meters. A maximum axial extent of the wave absorption elements corresponds to the length of the platform module.

For breaking waves of the waves, the platform 10a has wave breaking elements 280a, 282a, 284a. The wave breaking elements 280a, 282a, 284a are arranged above the water level 22a on the steel girders 86a, 88a, 108a, 110a. The breakwater elements 280a, 284a are arranged above the steel girders 86a, 88a, 108a, 110a. The breakwater element 282a is disposed below the steel girders 86a, 88a, 108a, 110a. The breakwater elements 280a, 282a, 284a are arranged between the shaft absorption elements 26a, 28a. The wave breaking elements 280a, 282a, 284a break the wave of the wave mainly along the wave absorbing elements 26a, 28a in the direction of the geometric center of the platform 10a. The breakwater elements 280a, 282a, 284a are arranged in two different horizontal planes.

In this embodiment, in the outer edge region 24a and the intermediate region 82a, a plurality of wave breaking elements are arranged on each steel beam, wherein a number of the Welbrechelemente decreases in the direction of the geometric center. In the central region 36a, no breakwater elements are arranged. All breakwater elements are formed and arranged analogously to the breakwater elements 280a, 282a, 284a. For spacing connection of the wave absorption elements of the platform 10a along the direction perpendicular to the main extension direction 42a and to the water level 22a parallel direction 84a, the platform device has a plurality of joint-free connection units. The connection units connect the shaft absorption elements at a defined distance 48a without joints. The defined distance 48a is substantially smaller than the length of the platform module. In this embodiment, the length of the platform module is approximately ten times the defined distance 48a. The defined distance 48a is 12 m in this embodiment.

FIG. 3 shows a connection unit 44a and a connection unit 46a. The connection units 44a, 46a connect the wave absorption element 26a to the wave absorption element 28a at the defined distance 48a.

The connection unit 44a is designed in several parts. The connection unit 44a has two steel beams 86a, 88a and four joints 90a, 92a, 94a, 96a. The steel beams 86a, 88a are arranged parallel to each other at a distance 286a. The steel beams 86a, 88a are arranged transversely to the wave absorption elements 26a, 28a. The steel beams 86a, 88a are protected against corrosion. The steel beams 86a, 88a are each designed as IPE steel beams. The steel beams 86a, 88a are each formed as a shaped steel beam with an I-profile. The distance 286a is 2 m. The connection points 90a, 92a of the connection unit 44a connect the shaft absorption element 28a to the steel supports. like 86a, 88a. The connection points 94a, 96a of the connection unit 44a connect the shaft absorption element 26a to the steel beams 86a, 88a. The joint 90a has a bearing block, two

Doubling elements 98a, 100a, a load distribution element 102a and two attachment elements 104a, l ^' 06a (see Figures 4 and 5). The doubling elements 98a, 100a prevent wear of the wave absorption element 28a by the connecting elements 104a, 106a. The doubling elements 98a, 100a are each designed as half shells. The doubling elements 98a, 100a partially surround the wave absorption element 28a along its inner circumference. The doubling element 98a is partially disposed between the attachment elements 104a, 106a and the wave absorption element 28a and partially above the water level 22a. The doubling element 100a is arranged entirely between the attachment elements 104a, 106a and the wave absorption element 28a and entirely below the water level 22a. It abuts the load distribution element 102a along its outer circumference. The doubling element 100a abuts on the attachment elements 104a, 106a. The doubling elements 98a, 100a each consist of polyurethane (PUR). The load distribution element 102a distributes an attachment force to the doubling element 100a and thus to the wave absorption element 28a. It is designed as a half-shell. The load distribution element 102a is arranged between the connection elements 104a, 106a and the doubling element 100a. An extension of the load distribution element 102a in the direction of the main extension direction 42a is smaller than an extension of the doubling elements 98a, 100a in the direction of the main extension direction 42a. The load distribution member 102a is formed as a load distribution plate. The tie bars 104a, 106a provide the connection between the steel beam 86a and the wave absorption element 28a. The connecting elements 104a, 106a form the bearing block. They provide the connection power. The connection elements 104a, 106a are round or U-shaped. They are arranged side by side. The connection elements 104a, 106a are each formed as steel cables.

For connecting the connection elements 104a, 106a to the

Steel beams 86a, the connection elements 104a, 106a at their ends or at their beginnings each have a thread.

The connection elements 104a, 106a are connected in a form-fitting manner to the steel carrier 86a via two nuts arranged at both ends or beginnings. Within the steel carrier 86a designed as an IPE steel carrier, the connecting elements are axially separated by a dividing wall of the I-profile. The connection points 92a, 94a, 96a are formed analogously to the connection point 90a. The joint 92a connects the steel beam 88a to the shaft absorption element 28a, the joint 94a connects the steel beam 86a to the shaft absorption element 26a, and the joint 96a connects the steel beam 88a to the shaft absorption element 26a.

The connection unit 46a is analogous. The connecting unit 46a has two steel beams 108a, 110a and four connecting points 112a, 114a, 116a, 118a. Of the Steel beam 88a of the connection unit 44a is arranged at a distance 288a to the steel girder 108a of the connection unit 46a transversely on the shaft absorption elements 26a, 28a. The steel girders 86a, 88a, 108a, 110a are designed as flat steel girders. The breakwater elements 280a, 282a, 284a are arranged transversely to the steel girders 86a, 88a, 108a, 110a. The distance 288a is 4 m.

The connection points 112a, 114a, 116a, 118a are analogous to the connection points 90a, 92a, 94a, 96a of the connection unit 44a. The joint 112a connects the wave absorption element 28a to the steel beam 108a. The joint 114a connects the wave absorption element 28a to the steel beam 110a. The joint 116a connects the wave absorbing member 26a to the

 Steel beam 108a. The joint 118a connects the wave absorbing member 26a to the steel beam 110a. All connection units of the platform device are designed analogously to the connection units 44a, 46a.

For faster overcoming of a path in the platform 10a, for example for the maintenance of the platform 10a, a part of the connection units or all connection units of the

Platform 10a have bent or bent steel beams. In principle, all connection units can only have flat steel beams.

In this embodiment, one part of the connection units has bent steel beams and another part of the connection units has plane steel beams. The connection unit 290a has a cranked steel beam 292a. The Connection unit 290a connects the wave absorption element 28a at the defined distance 48a with the wave absorption element 30a. The cranked steel beam 292a of the connection unit 290a has two projections 294a, 296a and a plane 298a. The plane 298a is disposed between the protrusions 294a, 296a. Through the protrusions 294a, 296a, the plane 298a is arranged at a distance 300a above the water level 22a. The distance 300a provides a headroom between the wave absorption elements 28a, 30a for a watercraft 302a. The bent steel beam 292a of the connection unit 290a is bent by about 45 degrees as compared with the flat steel beam 110a of the connection unit 46a. The distance 300a is 2.50 m. A length 304a of the plane 298a is about 8 m. A length 306a of the projections 294a, 296a is about 2.80 m. A length of the cranked steel beam 292a is 15 m, wherein about 0.70 m of the steel beam 292a each at both ends for connection to the respective Wellenabsorp- tion elements 28a, 30a omitted.

The connecting units, which have the bent steel beams, are arranged one behind the other along the welded-together wave absorption elements. By the cranked steel girders, the watercraft 302a can be moved along the wave absorption elements, whereby paths within the platform 10a can be overcome more quickly. The wave absorption elements arranged in the outer edge region 24a are connected only by connecting units comprising the flat steel beams

(see Figures 6 and 7). Only the wave absorption elements in the intermediate region 82a and in the central region 36a are partially connected by connecting units having bent steel beams (see Fig. 8). Between the wave absorption elements, which are connected by bent steel beams, no breakwater elements are arranged. All bent steel beams are analogous to the

bent steel beams 292a formed.

For carrying a first payload, the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a and the further wave absorption elements of the platform 10a are each designed as buoyancy elements. The wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a and the other wave absorption elements of the platform 10a provide buoyancy including the first payload, a weight of the connection units 44a, 46a, and a weight of the other connection units of the platform 10a Weight of the walkable ground, a weight of the breakwater elements and their own weight above the water level 22a holds or carries. The shaft absorption elements, the breakwater elements and the connection units form the platform 10a. In particular, the platform 10a carries the first payload above the water level 22a. The first payload causes a displacement of the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a of 80% of their own volume. By the first payload is a volume of 80% of the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a below the water level 22a. A dimensioning of the wave absorption elements 26a, 28a, 30a, 32a,

182a, 184a, 268a depends on the first payload, the substantially sets the displacement of the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a of 80%. For the realization of a soft construction, the dimensioning of the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a, 268a takes place solely on the basis of an assumption of the first payload, whereby a deflection is disregarded. The first payload is formed as a weight of the first kind of the power generation unit 12a, 14a, 16a, 18a, 308a, 310a, 312a, 314a and the rest of the photovoltaic power generation unit. The first payload is thus formed by the power generation units formed by photovoltaic systems. The platform 10a substantially carries the power generating units formed by the photovoltaic panels.

The power generating unit 12a formed by the photovoltaic system, the power generating unit 14a formed by the photovoltaic system, the power generating unit 16a formed by the photovoltaic system, and the power generating unit 18a formed by the photovoltaic unit are disposed on the steel beams 86a, 88a and the steel beams 108a, 110a, respectively (see FIG 3, 6 and 7). The power generation units 12a, 14a are disposed on the steel girders 86a, 88a of the connection unit 44a and the power generation units 16a, 18a on the steel girders 108a, 110a of the connection unit 46a. The power generation units 12a, 14a are arranged offset with respect to the direction 84a to the power generation units 16a, 18a. The power generating unit 308a formed by the photovoltaic plant and the power generating unit 312a formed by the photovoltaic power plant are bent over Steel beam 292 a of the connection unit 290 a arranged. The energy generating unit 310a formed by the photovoltaic system and the energy generating unit 314a formed by the photovoltaic system are arranged on a bent steel support not shown in detail between the wave absorption elements 28a, 30a. The steel support, not shown, is arranged behind the bent steel support 292a. The power generation unit 16a includes a steel mesh structure 120a, a photovoltaic module (PV module) 122a, and a deflection unit. The PV module 122a is mounted on the steel structure 120a and mounted on the steel beams 108a, 110a. Through the steel structure 120a, the PV module 122a is disposed at a distance 316a above the water level 22a. The steel construction 120a is stiffened. By means of the deflection unit, the steel structure 120a and the PV module 122a are movable in an angular range with respect to the main extension direction 42a of the wave absorption element 28a, whereby the steel structure 120a and the PV module 122a partially follow a movement corresponding to the swell (see dashed line in FIG in Fig. 7). The distance 316a is 6 m. The energy generating units 12a, 14a, 18a, 308a, 310a, 312a, 314a formed by the photovoltaic systems are designed analogously. The power generation unit 12a has a PV module 124a, the power generation unit 14a a PV module 126a and the power generation unit 18a a PV module 128a, which are each arranged partially movable via a deflection unit. The power generation unit 12a further comprises a steel mesh construction 130a, the power generation unit 14a a steel mesh construction 132a, and the power generation unit 18a a steel mesh construction 134a. The PV module 124a or 126a is arranged to the PV module 128a or 122a at a distance 318a between the wave absorption elements 26a, 28a. The distance 318a is 1 m.

The power generation units 308a, 310a, 312a, 314a each have a PV module 320a, 322a, 324a, 326a, which are each mounted on the steel beam 292a via a steel construction 328a, 330a, 332a, 334a. A distance of the PV modules 320a, 322a, 324a, 326a above the water level 22a is the same as the distance 316a of the PV modules 12a, 14a, 16a, 18a above the water level 22a. Thus, the steel structures 328a, 330a, 332a, 334a and the steel structures 120a, 130a, 132a, 134a have different heights.

All of the energy generation units formed by the photovoltaic systems are designed analogously to the energy generation units 12a, 14a, 16a, 18a, 308a, 310a, 312a, 314a. A distance that the PV modules have above the water level 22a decreases in the direction of the geometric center. PV modules arranged in the outer edge area 24a have a distance above the water level 22a of approximately 6 m. PV modules arranged in the intermediate area 82a have a distance above the water level 22a of approximately 4 m. PV modules arranged in the central area 36a have a distance above the water level 22a of approximately 1 m. For carrying a payload independent of the first payload, the platform device has a plurality of buoyancy elements. In Figures 9 to 12, only four buoyancy elements 50a, 52a, 54a, 56a are shown. The remaining drive elements are designed substantially analogously.

All buoyancy elements are independent of the wave absorption elements and thus of the platform 10a. The buoyancy elements have a buoyancy,. independently holds its own weight, a weight of coupling units provided for coupling the buoyancy elements with the wave absorption elements and the independent payload over the water level 22a. The wave absorption elements thus absorb only the first payload. All of the buoyancy elements present in the platform device collect the independent payload together. A buoyancy of the drive elements may differ in comparison to the other buoyancy elements. The independent payload is a sum of a weight of the second type of power generation unit, a weight of the dockyard, a weight of the staff quarters, a weight of the convention center, a weight of the communication tower, a weight of the heliport, a weight of the seawater cable, a weight of a fastening device and a weight of an energy storage and energy conversion unit 58a. The independent payload is a generic term for all additional loads required to operate the platform device. The independent payload formed as an additional load and thus the buoyancy elements are arranged in the central region 36a of the platform 10a within the platform 10a, in which the wave action is substantially canceled by the wave absorption elements. The power generation units formed by wind power plants, the landing quays, the staff accommodations, the convention center, the communication tower, the heliport, and the energy storage and power conversion unit 58a are disposed in the central area 36a. The power generating units formed by wind turbines are arranged at a distance of at least 500 m from the outer edge 40a of the platform 10a within and thus in the direction of the geometric center of the platform 10a.

A position of the buoyancy elements is dependent on a position of the weight or the load to be applied. A number and the buoyancy of the respective buoyancy elements depend on the weight to be borne or the load to be supported. The buoyancy elements are thus arranged at the position in the platform 10a or in the platform device, where the additional buoyancy is required for an additional load of the independent payload. The buoyancy elements are each arranged between two Wellenabsorptionselemen- th.

In Figures 9 and 10, the buoyancy element 50a is shown. The buoyancy member 50a is disposed between the wave absorbing member 30a and the wave absorbing member 32a. The remaining, unspecified Drive elements are formed analogously or arranged analogously between wave absorption elements.

The buoyancy element 50a is designed as a precast concrete part. The precast concrete element is standardized. The buoyancy element 50a is seawater resistant and glass fiber reinforced. The buoyancy element 50a has a chamber 136a. By flooding, ie by filling the chamber 136a with seawater, the buoyancy of the buoyancy element 50a can be adapted to the weight to be supported or to the load to be carried. The buoyancy element 50a also has a check shaft 138a and sliding bulkheads 140a. The Schlingerschotten 140a separate the chamber 136a of the buoyancy element 50a up to a defined height in four individual chambers. The buoyancy element 50a has a length 146a of 10 m, a width 144a of 10 m and a height 142a of 7 m. The buoyancy element 50a has the weight of 260 tons. A draft is thus 2.6 m. The buoyancy and thus the portable independent payload of the buoyancy element 50a can be adjusted by flooding the chamber 136a between 0 tons and 300 tons.

For coupling or for fastening the buoyancy element 50a and the further buoyancy elements of the platform device to the respective wave absorption elements, the platform forming device has a plurality of coupling units. The buoyancy member 50a is fixed by a coupling unit 148a.

The coupling unit 148a attaches the buoyant member 50a to the wave absorbing members 30a, 32a. The coupling unit 148a has four steel beams 150a, 152a, 154a, 156a and a buoyancy element fixture 158a. The steel beams 152a, 156a are arranged along the corresponding shaft absorption element 30a, 32a. The steel girders 150a, 152a, 154a, 156a are connected to the wave absorption elements 30a, 32a, the steel girders 150a, 154a being transverse to the wave absorption elements 30a, 32a, ie perpendicular to the

Steel beams 152a, 156a are arranged. The buoyancy element fixing 158a binds the buoyancy element 50a to the steel beams 150a, 152a, 154a, 156a and thus to the shaft sorption elements 30a, 32a. To connect the buoyancy element fixing 158a to the steel beams 150a, 152a, 154a, 156a, corners of the steel beams 150a, 152a, 154a, 156a each have a connecting piece 160a, 162a, 164a, 166a. A distance of the steel beams 150a, 154a to each other is about 12 m. A distance between the steel beams 152a, 156a to each other is also 12 m.

Due to the buoyancy element fixing 158a, the buoyancy element 50a is fixed between the wave absorption elements 30a, 32a. The buoyancy element fixing 158a has four fixing elements 168a, 170a, 172a, 174a designed analogously. The fixing elements 168a, 170a, 172a, 174a have a V-shape, wherein legs of the V-shape are pulled apart. The fixing elements 168a, 170a, 172a, 174a fasten in each case one side of the buoyancy element 50a to the respective connecting piece 160a, 162a, 164a, 166a.

For flooding and emptying the chamber 136a of the buoyancy element 50a, and thus for adjusting the buoyancy of the drive element 50a, the platform device has a pump unit (not shown). The pump unit conveys Seawater enters the chamber 136a or returns the seawater from the chamber 136a back into the sea or back and forth between the various buoyancy elements. The pump unit has a pumping capacity of 360 tons per hour.

To adjust the buoyancy of the entire buoyancy elements for supporting the independent payload, the platform device comprises a plurality of pump units, not shown. All buoyancy elements of the platform device are designed analogously to the buoyancy element 50a.

In Figs. 11 and 12, an arrangement of four buoyancy elements 50a, 52a, 54a, 56a for supporting a weight of load of the power generating unit 20a formed by the wind turbine is shown. In this case, the buoyancy element 54a is arranged between the two wave absorption elements 182a, 184a. A recording of the weight of the energy generating units formed by the wind power stations is realized analogously by four buoyant elements in each case.

The four buoyancy elements 50a, 52a, 54a, 56a are arranged offset from each other along a circular line 90 degrees. The four buoyancy elements 50a, 52a, 54a, 56a are each arranged between two wave absorption elements. For arranging the wind power plant formed as a power generation unit 20a on the four buoyancy elements 50a, 52a, 54a, 56a, the power generation unit 20a is mounted on two transport buoyancy elements 176a, 178a and transported to a corresponding position. The power generation unit 20a includes a lattice girder 180a. The lattice girder 180a has a center. The center of the lattice girder 180a corresponds to a center of the arrangement of the four drive elements 50a, 52a, 54a, 56a. The lattice girder 180a has four ends, each forming a bearing surface. In each case one end lies with the bearing surface on a buoyancy element 50a, 52a, 54a, 56a. The weight or the load of the energy generating unit 20a designed as a wind turbine is distributed uniformly on the four buoyancy elements 50a, 52a, 54a, 56a. The four buoyancy elements 50a, 52a, 54a, 56a carry the weight of the wind turbine power generation unit 20a.

The four buoyancy elements 50a, 52a, 54a, 56a receive tilting moments of the energy generating unit 20a designed as a wind turbine. To set a vertical position of the power generating unit 20a with changed tilting moments resulting from altered wind loads, the pumping unit fills chambers 136a of the four buoyancy elements 50a, 52a, 54a, 56a. The pump unit changes the buoyancy of the four buoyancy elements 50a, 52a, 54a, 56a, wherein the buoyancy of the four buoyancy elements 50a, 52a, 54a, 56a may differ from one another. The pump unit adjusts the lift of the individual buoyancy elements 50a, 52a, 54a, 56a as a function of the present tilting moments or the prevailing wind loads.

For a better distribution of the weight or the load on the buoyancy elements 50a, 52a, 54a, 56a and thus for the stabilization of the energy generating unit 20a, the energy generating unit 20a has a shaft 186a, which is mounted on The power generation unit 20a partially extends below the lattice girder 180a and the buoyancy elements 50a, 52a, 54a, 56a. The shaft 186a lies partially below the water level 22a when the energy generating unit 20a is set up.

For clamping or for connecting the shaft 186a of the energy generating unit 20a with the buoyancy elements 50a, 52a, 54a, 56a, the energy generating unit 20a has

Clamping elements 188a on. The bracing elements 188a clamp the shaft 186a both above and below with respect to the buoyancy elements 50a, 52a, 54a, 56a. The shaft 186a is connected to the four buoyancy elements 50a, 52a, 54a, 56a below and above the water level 22a by the bracing elements 188a. By means of the bracing elements 188a, the energy generating unit 20a formed by the wind power plant is set up by winds in the seawater. On a floating crane can thus be dispensed with. In this embodiment, the power generation unit 20a includes a rotor 190a having a rotor diameter of 115 m

Shaft 186a with a length of 120 m and a power of 5 megawatts. The shaft 186a protrudes about 20 m into the seawater when the energy generating unit 20a is set up. For recovering hydrogen by means of energy generated by the power generation units 12a, 14a, 16a, 18a, 20a, the platform device has a plurality of power conversion units 58a. The energy conversion units 58a are designed as electrolysis units. The energy conversion units 58a gain or generate with the aid of the energy generation units 12a, 14a, 16a, 18a, 20a. Energy from seawater produced the hydrogen. The energy conversion units 12a, 14a, 16a, 18a, 20a are arranged in the central region 36a, in which essentially the wave effect is canceled out or there is no swell.

For storing the energy generated by the power generation units 12a, 14a, 16a, 18a, 20a, the platform device has a plurality of energy storage units 58a. In this embodiment, hydrogen storage tanks form the energy storage units 58a. The recovered energy is stored as hydrogen in the hydrogen storage tanks. In principle, the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a can also absorb the hydrogen in their cavities and thus easily form an energy storage unit. The recovered energy is thereby stored in the form of the hydrogen in the wave absorption elements. The hydrogen is stored in the cavities of the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a. These are the wave absorption elements 26a, 28a, 30a, 32a, 182a, 184a with a hydrogen-impermeable

Substance coated and / or made of a hydrogen-impermeable material.

Further, the hydrogen can be converted back to electrical energy, thereby providing a reliable power supply by the platform device. The generation of energy by the hydrogen occurs when an energy demand exceeds the energy generated on the platform device. In principle, the re-conversion of the hydrogen can also take place on the coast 72a next to the transfer station, the hydrogen being produced by means of pipelines or water. is transported by the platform device to the coast 72a. The back conversion of the hydrogen may be by combustion or by a fuel cell.

For fastening the platform 10a to a seabed 336a, the platform device has a fastening and deflecting device (compare FIGS. 13 to 15). The fastening and deflecting device comprises a fastening unit 338a and four attachment and deflection units 60a, 62a, 64a, 66a. The fixing unit 338a forms a primary anchorage. The attachment unit 338a secures a region 340a around the geometric center on the seabed 336a. The attachment unit 338a has four anchor points on the seabed 336a, with only the anchor points 342a,

344a can be seen. Furthermore, the attachment unit 338a has four fastening points on the platform 10a, wherein only the attachment points 346a, 348a can be seen. The attachment points 346a, 348a have a defined distance 350a from each other. The attachment point 346a is connected to the seabed 336a via the anchor point 344a. The attachment point 348a is connected to the seabed 336a via the anchor point 342a. The two invisible attachment points and the attachment points 346a, 348a form a shape that corresponds to a reduced shape of the platform 10a. The four attachment points are arranged in a square shape. The attachment point 346a is connected to the anchor point 344a via a connecting element 352a. The attachment point 348a is connected to the anchor point 342a via a connecting element 354a. The invisible anchor points are aligned with the invisible mounting each point connected by means of non-visible fasteners. The connecting elements 352a, 354a and the non-visible connecting elements intersect at the geometric center. The connecting elements 352a, 354a and the non-visible connecting elements are designed analogously. The anchor points 342a, 344a and the invisible anchor points are formed analogously. The defined distance 350a is 600 m. The fastening and deflection units 60a, 62a, 64a, 66a form a torsional stress. The attachment and deflection units 60a, 62a, 64a, 66a attach one side of the platform 10a to the seabed, respectively. The attachment and deflection unit 60a has two attachment points 192a, 194a on the platform 10a and an anchor point 196a on the seabed. The attachment points 192a, 194a are arranged at a defined distance 356a from the outer edge 40a of the platform 10a in the direction of the geometric center of the platform 10a on the platform 10a. The attachment points 192a, 194a are arranged in the central region 36a. The two attachment points 192a, 194a are arranged spaced apart on the platform 10a. The anchor point 196a and the two attachment points 192a, 194a are connected to one another by a connection element 198a.

Furthermore, the attachment and deflection unit 60a has two deflection points 200a, 202a. The deflection points 200a, 202a are at a defined distance 356a from the outer edge 40a of the platform 10a in the direction of the geometric center of the Platform 10 a arranged on the platform 10 a. The defined distance 356a of the attachment points 192a, 194a corresponds to the defined distance 356a of the deflection points 200a, 202a. The two deflection points 200a, 202a are also arranged in the central region 36a. The two deflection points 200a, 202a are arranged spaced apart on the platform 10a. A distance between the two deflection points 200a, 202a is greater than a distance between the two attachment points 192a, 194a.

In the fifteen o'clock position, the distance between the anchor point 196a and the turnaround point 200a of the attachment and deflection unit 60a is approximately 1600 meters, and the distance between the anchor point 196a and the deflection point 202a is approximately 3600 meters. The distance between the deflection points 200a, 202a remains unchanged at 2400 meters. The distances of the anchor point 196a to the deflection points 200a, 202a and the distances of the two deflection points 200a, 202 of the fastening and deflection unit 60a are at distances of the anchor points 220a, 222a, 224a to the respective deflection points 200a, 202a, 216a, 218a of the corresponding attachment - And deflecting units 62a, 64a, 66a analog.

The grid elements have a mesh size that is predetermined by marine biologists. In this embodiment, the grid elements depend on the corresponding wave absorption element about 2 m in a depth of the sea. The grid elements are designed as stainless steel mesh.

A production of the platform 10a is shown schematically in the figure 18 and partially shown. All wave absorption elements of the platform 10a are manufactured in a bay on the coast 72a directly on the sea 70a. The wave absorption elements are extruded in the bay on land. The bay is sheltered from the wind. The bay is protected in main wind wave direction.

To fabricate the wave absorbing elements, a wave absorbing element fabrication 248a is installed in the bay. By the wave absorption element fabrication 248a, the wave absorption elements are extruded adjacent to each other four-row and 20 m long and welded together in a region 250a, each with a bulkhead element. One row has six wave-absorbing elements welded together. The four rows of welded wave absorption elements welded together are stored in the region 250a. These are moved on roller bearings in an area 252a. In the area 252a, by means of a gantry crane, the steel girders of the connection unit, which are stored in a storage space 254a, are mounted, thereby connecting the wave absorption elements to each other. The interconnected wave absorption elements are moved by means of a ramp in a region 256a. In area 256a, PV modules mounted on the shore side are mounted on the steel girders of the connection unit and thus on the shaft absorption elements by means of a tower crane 258a. The fully assembled PV modules are stored at a storage location 260a. The interconnected wave absorption elements and the fully assembled PV modules correspond to a platform module. The platform module is then pushed onto the sea 70a. When buoyancy elements on the connected wave absorption elements or on the

Platform module are provided, the wave absorption elements are moved into a region 262 a. The buoyancy elements are inserted in the region 262a by means of another tower rotary crane 264a from a storage location 266a to a previously programmed position in the interconnected wave absorption elements, fixed and pushed onto the sea 70a. The connected wave absorption elements with the buoyancy elements also correspond to a platform module. The wave absorption elements in the region 256a and the region 258a lie in the sea 70a.

To produce the platform 10a, a plurality of such platform modules on the sea 70a are swum in the bay and connected together to the platform 10a, whereby the power generating units formed by wind turbines in the bay are also arranged on the buoyancy elements by means of the transport buoyancy elements. The entire platform is then towed and anchored to a destination on the sea 70a. In an alternative and preferred manufacture of the platform 10a, the wave absorption elements in the bay are extruded directly into the sea 70a. At this time, after the wave absorbing member fabrication 248a, the wave absorbing members first pass through a cooling unit. The cooling unit cools the wave absorbing elements, thereby ensuring strength and shape of the wave absorbing elements. After the cooling unit, the wave absorption elements are welded together by a respective bulkhead element 270a. Thereafter, the welded-together wave absorption elements reach the sea 70a due to an extrusion movement. On an intermediate storage on land of welded together wave absorption elements is omitted. The production of the platform modules takes place in the sea 70a, as described above, wherein the connection of the wave absorption elements with the steel beams also takes place in the sea 70a.
