Definitions

  • the invention relates to floating structures, in particular floating structures made up of frames supported by buoyant members. More specifically, the invention relates to floating structures which provide a platform for an installation, such as an array of PV panels, a desalination plant, or an energy storage unit, or for some other type of use.
  • the floating structures may be used both inshore, e.g. on rivers or lakes, or offshore.
  • conventional floating structures usually comprise a relatively large rigid frame, which is either supported by separate buoyant members or which is made up of hollow elements providing inherent buoyancy.
  • the frame of a conventional floating structure is usually rectangular.
  • Conventional floating structures have a relatively high wave resistance, leading to relatively high loads on their frames, which must therefore be strong and comparatively heavy.
  • rectangular frames can accommodate movement as a result of frontal waves, they are not suitable for accommodating torsional wave movements.
  • Floating structures made up from a number of rectangular frames require relatively complex couplings and a relatively wide spacing to accommodate torsional wave movements.
  • Prior art document WO 2017/118998 Al discloses a rectangular floating solar platform which includes a unified floating structure that is formed of a horizontal mesh of one or more horizontal support members connected to each other in a matrix pattern, and one or more vertical support members fixedly mounted on the horizontal mesh.
  • a horizontal planar modular deck is fixedly mounted on the unified floating structure and supports one or more arrays of solar panels. This floating structure is too rigid to follow the waves, resulting in high wave loads on the structure and/or large air gap requirements between the wave surface and the array of solar panels.
  • Prior art document WO 2017/023536 Al discloses a floating solar array made of a closed loop of flexible high density polyethylene pipes with elbows, T fittings and couplings forming a pontoon.
  • An anti-lift membrane fills with water and mitigates the wind forces.
  • the array can have a stabilizing skirt going downwardly from the border of the array, especially when it is used offshore in the sea.
  • This document shows not only rectangular pontoons, but also hexagonal and octagonal pontoons.
  • Prior art document KR 101997077 Bl discloses a floating water solar power generation module which comprises: a closed circular or elliptical support frame provided at the outside of a structure; a support net having a rope provided in a lattice shape inside the support frame; an array of solar panels on the support net; and a main floating body coupled to one side of the support frame.
  • a floating structure which comprises a plurality of interconnected frames and a plurality of buoyant members supporting the structure, and wherein at least some of the frames are substantially triangular in planform.
  • the floating structure may be built relatively easily and swiftly by assembling the frames.
  • a plurality of smaller frames is easier to stock, transport and handle than a single large frame. For instance, if the edges of the frames are designed to be no longer than 12 m, they may be transported in standard 40 feet containers.
  • Triangular frames rather than the commonly used rectangular frame, loads on the structure can be absorbed and/or transferred in a more efficient manner.
  • Triangular frames are particularly well suited for absorbing and/or transferring shear loads within the plane of the triangle and have a relatively high strength to weight ratio.
  • the floating structure might include some frames having a different planform, e.g. a row of rectangular frames at an edge or in a centre of the structure, in one embodiment all frames are substantially triangular in planform. In this way the floating structure as a whole is optimally suited for accommodating in-plane shear loads.
  • adjacent triangular frames are movably connected.
  • movably connected it is meant that a frame has one or more of six possible degrees of freedom with respect to an adjacent frame.
  • adjacent triangular frames are pivotably connected.
  • a pivotable connection allows the frames to more or less conform to the waves on the body of water on which the structure floats, thus reducing the loads on the structure even further.
  • the triangular frames may have substantially the same shape. In that way they can be mounted relatively closely together.
  • a uniform floating structure may be achieved in an embodiment wherein the triangular frames have substantially the same dimensions.
  • At least one of the triangular frames may have dimensions which are a multiple of the dimensions of another one of triangular frames. In that way the floating structure might be made up of a combination of larger and smaller triangles.
  • each triangular frame may have a base, an apex and two sides connecting opposite ends of the base with the apex, and adjacent triangular frames may be connected along their respective sides such that the base of a first frame is closest to the apex of a second frame and the base of the second frame is closest to the apex of the first frame.
  • a row of alternating triangles may be formed, such that the series of bases at opposite sides may form substantially continuous edges.
  • each triangular frame may have a base, an apex and two sides connecting opposite ends of the base with the apex, and adjacent triangular frames may be connected along their respective bases. In this way two interconnected triangular frames may form a diamond.
  • the triangular frames may comprise right-angles triangles. Such triangular frames may easily be combined to form a rectangular floating structure.
  • the triangular frames may comprise isosceles triangles. In this way a uniform floating structure may be formed.
  • Uniformity of the floating structure may be further increased by an embodiment in which the triangular frames comprise equilateral triangles.
  • the isosceles triangle may have an apex angle between about 20-120°, in particular an apex angle of 60°.
  • At least some of the triangular frames may have at least one corner which is chamfered or rounded.
  • corner which is chamfered or rounded.
  • At least some of the triangular frames may have a substantially open load-bearing structure, the three sides of the triangle comprising beams connected at or near their ends.
  • the beams forming the sides of the triangle may support an internal grid or a platform.
  • each triangular frame is supported by at least one buoyant member.
  • the frames are self-supporting and do not rely on being connected to other frames for their buoyancy.
  • the at least one buoyant member may be connected to the respective triangular frame by at least one post. In this way a distance is maintained between the floating structure and the surface of the body of water in which it floats.
  • each triangular frame may be supported by at least three buoyant members.
  • each buoyant member may be connected to a respective triangular frame near a corner of the frame. In this way stability of the floating structure is even further increased.
  • each buoyant member when adjacent triangular frames are connected along their respective sides or bases, each buoyant member may be connected to a respective triangular frame at a position along a side or base which is offset with respect to a position of a buoyant member along a side or base of an adjacent triangular frame to which the first side or base is connected. In this way there is no risk of buoyant members of adjacent triangular frames colliding during movement of the frames on waves of a body of water on which the structure floats.
  • the floating structure may further comprise anchoring means for maintaining the floating structure substantially at a fixed location in a body of water.
  • the floating structure may further comprise an installation supported by the floating structure.
  • the installation may be arranged on the internal grid or the platform of a respective triangular frame.
  • the installation may comprise a plurality of PV panels.
  • the installation could comprise e.g. a desalination plant, or an energy storage unit, e.g. an array of batteries.
  • Other possible uses for the floating structure are the generation of wind energy through one or more turbines, or the generation of wave energy.
  • a further floating structure could support energy intensive activities, like e.g. a hydrogen production unit, a hydrogen-to-fuel conversion plant, or a data center.
  • the floating structure could also be used for urbanization, i.e. housing and/or recreation, for agriculture or for aquaculture.
  • the floating structure could be used as an offshore mooring or satellite port, where ships could load or offload cargo or supplies, in particular fluidic cargo that can be brought ashore through pipelines.
  • the number of buoyant members and their volume, as well as a length of the at least one post may be selected as a function of the weight of a respective frame and its installation, such that the frame is supported at a distance above a still waterline of a body of water in which the floating structure is used. In this way the frame can be kept free of waves on the body of water on which the structure is floating.

  • adjacent rows 5 are arranged in the shape of a rooftop, and walkways 18 are shown to be arranged between each pair of rows 5.
  • each triangular frame 2 is covered by the array 4 of PV panels, it is also conceivable to reserve a part of the surface area for other parts of the installation, like e.g. control electronics, a transformer or batteries for storage.
  • the floating structure 1 could be made up of triangular frames 2 carrying PV panels and one or more triangular frames 2 carrying other parts of the installation.
  • the floating structure 1 could carry a different type of installation, e.g. a desalination plant, a hydrogen production plant or some other installation that requires a large amount of space but involves only limited or no human intervention.
  • the triangular frames 2 could be provided with a platform, rather than an internal grid.
  • the buoyant members 3 have the shape of an oblate ellipsoid, i.e. a body of revolution about a vertical axis on the basis of an ellipse having a major axis which is horizontal and a minor axis which is vertical.
  • an ellipsoid-shaped buoyant member which is described in detail in the applicant’s co-pending application entitled: “Floating structure having ellipsoid buoyant members”, has been found to have a very low wave drag, so that loads on each triangular frame 2 will be relatively low and its structure may be light. However, in situations where wave drag is less of an issue, more basic shapes of buoyant members could be considered, as illustrated by the rectangular buoyant members 23 shown in Figs. 10-12.
  • Loads on the triangular frames 2 are further reduced by keeping the frames 2 free of the water during normal use. Moreover, in this way the installation carried by the floating structure, in this case the array 4 of PV panels, is also protected from adverse effects due to the impact of waves.
  • the buoyant members 3 are almost fully submerged below the still waterline WL, while the frame 2 is supported at a height h above the still waterline. This is achieved by careful selection of the number of buoyant members 3 and their volume, as well as the length of the posts 6 as a function of the weight of each respective triangular frame 2 and the array 4 of PV panels which it supports.
  • the height h above the waterline WL is selected in accordance with the intended use. For inland waters, like lakes or even rivers, where wave heights will be limited, a free height of 1-2 m may be sufficient, whereas for offshore applications much higher structures, possibly with the frames 2 up to 25 m above the still waterline WL may be needed.
  • buoyant members 3 are shown to be fully submerged in this embodiment. However, it is also possible to give each buoyant member 3 a greater volume, so that it provides the required buoyancy even when it is only partially submerged. In that case the potential reserve buoyancy that may be generated when the buoyant member 3 is submerged to a greater extent than necessary for carrying the frame 2 may be used to increase dynamic stability of the floating structure 1. This reserve buoyancy will counter a downward movement of part of the triangular frame 2 when one side of the frame 2 is lifted by an approaching wave.
  • each triangular frame 2 may be chamfered or rounded, e.g. in order to provide sufficient strength or to avoid dangerously sharp angles. This is shown in the embodiment of Fig. 10.
  • This embodiment also includes an alternative arrangement of the three buoyant members 3, in which the buoyant members 3 are not arranged symmetrically with respect to a center line of the triangular frame 2, as is the case in the previous embodiments.
  • the buoyant members 3 of adjacent triangular frames 2 are located directly opposite one another in a direction transverse to the connected edge. Therefore these buoyant members could theoretically collide in case of pivoting movement of the frames 2 due to waves.
  • Figs. 1-9 the buoyant members 3 of adjacent triangular frames 2 are located directly opposite one another in a direction transverse to the connected edge. Therefore these buoyant members could theoretically collide in case of pivoting movement of the frames 2 due to waves.
  • each buoyant member 3A-C is connected to the frame 2 - through transverse girder 17 or a diagonal girder 20 - at a position along an edge which is offset with respect to a position of a buoyant member 3A-C along an edge of an adjacent triangular frame 2. If a triangular frame 2 is arranged to the right of the frame 2 shown in Fig. 10, with its apex pointing in the opposite direction, its first buoyant member 3A would not be directly opposite the first buoyant member 3A of the shown frame 2, but instead would be located in the vicinity of, but not directly opposite to the third buoyant member 3C.
  • FIG. 15A shows a frame 2 in the shape of an equilateral triangle, in which the angle a of the apex 13 and the angles P of the two other vertices 21 are all the same, as are the lengths of the two sides 12 and the base 11.

  • Fig. 15B illustrates the second embodiment of the frame 2 as shown in Figs. 2 and 9, in which the buoyant members 3 are arranged offset from the apex 13 and other vertices 21 of the isosceles triangle.
  • FIG. 15C shows another possible shape of the frame 2; a right-angle triangle having three different sides 11, 12A and 12B and three different angles a, and y, respectively.
  • the embodiments of Figs. 15B andl5C lend themselves to being combined into a rectangular floating structure 1 fairly easily.
  • a lozenge-shaped floating structure 1 could be made by connecting triangular frames as shown in Fig. 15C along their sides 11 and 12A bordering the right angle vertex 21 A.
