[0090] As shown in FIG. 1, in the floating arrangement 100, the at least one connection portion (or corner-connection-portion) 116 of the at least one support-floatation-unit 110 is coupled to the at least one connection portion (or corner-connection-portion) 136 of the at least one connecting-floatation-unit 130 to form a connection joint 150 which connects the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 in a side-by-side arrangement, whereby one of the two side walls 120a, 120b of the main body 112 of the at least one support-floatation-unit 110 abuts the longitudinal side wall 140a of the main body (or elongate main body) 132 of the at least one connecting-floatation-unit 130. According to various embodiments, the at least one connection portion (or corner-connection-portion) 116 of the at least one support-floatation-unit 110 may be fixedly coupled to the at least one connection portion (or corner-connection-portion) 136 of the at least one connecting-floatation-unit 130. Accordingly, the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 may be firmly attached in a manner so as to prevent relative movement between the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130. According to various embodiments, when the at least one connection portion (or corner-connection-portion) 116 of the at least one support-floatation-unit 110 and the at least one connection portion (or corner-connection-portion) 136 of the at least one connecting-floatation-unit 130 are connection lugs 11, 13, the at least one connection portion (or corner-connection-portion) 116 of the at least one support-floatation-unit 110 and the at least one connection portion (or corner-connection-portion) 136 of the at least one connecting-floatation-unit 130 may be placed in an overlapping manner with the respective eyeholes 12, 14 aligned, and a bolt may be inserted therethrough with a nut screwed onto the bolt from the other end of the bolt to clamp the connection lugs 11, 13 together. Accordingly, the connection joint 150 may include a bolt and a nut clamping or sandwiching the at least one connection portion (or corner-connection-portion) 116 (or connection lug 11) of the at least one support-floatation-unit 110 and the at least one connection portion (or corner-connection-portion) 136 (or connection lug 13) of the at least one connecting-floatation-unit 130 together. According to various embodiments, the connection joint 150 may connect the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 alongside each other so as to form the side-by-side arrangement. According to various embodiments, in the side-by-side arrangement, the side wall 120a of the main body 112 of the at least one support-floatation-unit 110, which may be a short side thereof, may be abutting the side wall 140a of the main body (or elongate main body) 132 of the at least one connecting-floatation-unit 130, which may be a long side thereof.

[0091] Referring to FIG. 1, in the floating arrangement 100 with the at least one connection portion (or corner-connection-portion) 116 of the at least one support-floatation-unit 110 and the at least one connection portion (or corner-connection-portion) 136 of the at least one connecting-floatation-unit 130 coupled together, a height, Hs, from the flat base 114 of the at least one support-floatation-unit 110 to a center 152 of the connection joint 150 is larger than a height, Hc, from the flat base (or elongate flat base) 134 of the at least one connecting-floatation-unit 130 to the center 150 of the connection joint 150. Accordingly, the flat base 114 of the at least one support-floatation-unit 110 extends downwards from a base level 134a of the flat base (or elongate flat base) 134 of the at least one connecting-floatation-unit 130 by a depth, Ds. According to various embodiments, the depth, Ds, may define an additional displacement volume of the at least one support-floatation-unit 110 configured to provide additional buoyancy to support the solar panel. According to various embodiments, the additional buoyancy may correspond to a portion of a weight of the solar panel, for example, the additional buoyancy may correspond to at least half of the weight of the solar panel, or at least two-third of the weight of the solar panel, or at least three-quarter of the weight of the solar panel, or substantially the weight of the solar panel.

[0092] In conventional floating system for supporting solar panels, various conventional floatation units (including support-floatation-units for supporting solar panels and connecting-floatation-units) forming the floating system are configured in a manner such that, when the various conventional floatation units are rigidly coupled together, the base of the various conventional floatation units are flushed and levelled. Accordingly, when solar panels are mounted on the conventional floating system, the additional weight of the solar panels are distributed to the various conventional floatation units through the connection joints such that the entire floating system may sink deeper together as a whole so as to displaced additional volume of water to provide additional buoyancy to support the solar panels. Hence, in the conventional floating system, the connection joint would serve to transfer the load from the weight of the solar panels for distribution to the various conventional floatation units when the solar panels are installed. Accordingly, the connection joint of the conventional floating system is constantly under load. In contrast, according to various embodiments, the floating arrangement 100 differs from the conventional floating system in that the at least one support-floatation-unit 110 of the floating arrangement 100 may sink deeper than the adjacently coupled at least one connecting-floatation-unit 130 when the solar panel is mounted on the at least one support-floatation-unit 110 such that the at least one support-floatation-unit 110, itself, may provide additional buoyancy to support the solar panel. Accordingly, in this manner, the floating arrangement 100 according to the various embodiments may minimize or eliminate the transferring of load via connection joints between floatation units for the distribution of the weight of the solar panel to other floatation units. Hence, the loading on the connection joint 150 between the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 in the floating arrangement 100 according to the various embodiments may in turn be minimized or eliminated when the solar panel is mounted on the at least one support-floatation-unit 110. Thus, the connection joint 150 between the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 may be preserved for and may be more effective in transferring load from external forces due to wind and/or sea wave and/or tidal forces.

[0093] FIG. 2 shows a perspective view of a floating arrangement 200 according to various embodiments. As shown, the floating arrangement 200 may include two rows of three interconnected connecting-floatation-unit 130 and one support-floatation-unit 110 connected between the two rows of connecting-floatation-unit 130. According to various embodiments, a floating arrangement may include any number of connecting-floatation-units 130 and support-floatation-units 110, and they may be connected in any configuration. According to various embodiments, a floating arrangement for supporting solar panels may include at least one support-floatation-unit for supporting a solar panel and at least one connecting-floatation-unit, or may include one or more support-floatation-units and one or more connecting-floatation-units, or may include a plurality of support-floatation-units and a plurality of support-floatation-units.

[0094] Referring to FIG. 2, respective main body 112, 132 of the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 may include at least one straight channel formation 118, 138 extending vertically (or perpendicularly or substantially perpendicularly) upwards with respect to respective flat bases 114, 134. According to various embodiments, the at least one straight channel formation 118, 138 of the respective main body 112, 132 of the at least one support-floatation-unit 110 and the at least one connecting-floatation-unit 130 may extend from the respective flat bases 114, 134 to the respective roofs 115, 135.

According to various embodiments, a same (or equal) number of straight channel formations 138 may be included (or formed) in each longitudinal side wall 140a of the main body (or elongate main body) 132 of the connecting-floatation-unit 130. For example, each longitudinal side wall 140a may include one or a plurality (i.e. the same or equal number) of straight channel formations 138 included in the longitudinal side wall 140a. According to various embodiments, each straight channel formation 138 included (or formed) in one of the two opposite longitudinal side walls 140a of the main body (or elongate main body) 132 of the connecting-flotation-unit 130 may be directly opposite another straight channel formation 138 included (or formed) in another of the two opposite longitudinal side walls 140a. That is, the at least one straight channel formation 138 included (or formed) in one of the two opposite longitudinal side walls 140a and the at least one straight channel formation 138 included (or formed) in another of the two opposite longitudinal side walls 140a may be positioned a same distance away from one (e.g. a first or a second) lateral side wall 104b of the main body (or elongate main body) 132 of the connecting-flotation-unit 130.

[0105] According to various embodiments, each straight channel formation 138 may define one continuous groove extending along an entire length of the straight channel formation 138 without interruption. In other words, between a starting point (or start) and an ending point (or termination) of each straight channel formation 138, the straight channel formation 138 may be devoid of any interruptions or protrusions or partitions or separators or abutting member or extending member etc. Accordingly, each straight channel formation 138 may extend from respective starting point to respective ending point of the straight channel formation 138 to form a continuous or unseparated or undivided or unpartitioned or unobstructed trough (or trench, canal etc.) and having an even (i.e. uninterrupted) surface (e.g. floor, base, bed etc.) along the trough. The surface may be a curved or v-shaped etc. surface, and may be a surface that is entirely exposed (e.g. exposed to the natural element(s), such as any one or more of atmosphere/air, liquid/sea etc.).

[0106] Referring to FIGS. 4C and 4D, the at least two straight channel formations 138 on two longitudinal side walls 140a of the main body (or elongate main body) 132 of the connecting-floatation-unit 130 may be part of a continuous endless channel formation which loop around the main body (or elongate main body) 132 of the connecting-floatation-unit 130. Accordingly, the at least two straight channel formations 138 on the two longitudinal side walls 140a of the main body (or elongate main body) 132 may be joined across a top (or across the elongate roof 135) of the main body (or elongate main body) 132 via a first horizontal running channel formation 139a, and the at least two straight channel formations 138 on two longitudinal side walls 140a of the main body (or elongate main body) 132 may be joined across a bottom (or across the flat base 134) of the main body (or elongate main body) 132 via a second horizontal running channel formation 139b. According to various embodiments, the first and second horizontal running channel formations 139a, 139b may run in a path forming an arrow-head shape on respective top and bottom of the main body (or elongate main body) 132. According to various embodiments, the arrow-head shape of the first horizontal running channel formation 139a (across the elongate roof 135) may point in a different direction (e.g. opposite direction, or substantially 180 degrees away about an axial axis of the main body 132) from the direction that the arrow-head shape of the second horizontal running channel formation 139b (across the flat base 134) points towards. For example, the arrow-head shape of the first horizontal running channel formation 139a may point towards a first longitudinal end 131 of the main body (or elongate main body) 132 (e.g. the end of the main body 132 where one of the two opposite lateral side walls 104b is positioned), and the second horizontal running channel formation 139b may point towards a second longitudinal end 133 of the main body (or elongate main body) 132 (e.g. the end of the main body 132 where another of the two opposite lateral side walls 104b is positioned).

Accordingly, the straight channel formations 118 of the two adjacent legs 122a, 122b of the support-floatation-unit 110, which are directed in the same first direction, may be formed in two opposite outward facing side wall 120b at respective end portion of the two adjacent legs 122a, 122b of the support-floatation-unit 110. The straight channel formations 118 of the two further adjacent legs 122c, 122d of the support-floatation-unit 110, which are directed in the same second direction, may be formed in two opposite outward facing side wall portion 120 at respective end portion of the two further adjacent legs 122c, 122d of the support-floatation-unit 110. According to various embodiments, each straight channel formation 118 may also or may alternatively be formed in the side wall 120a at respective end portion of respective leg 122a, 122b, 122c, 122d which is directed towards the connecting-floatation-unit 130.

[0108] Referring to FIG. 4A to FIG. 4D, the main body (or elongate main body) 132 of the connecting-floatation-unit 130 may include an overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 extending longitudinally outwards or directed away from an upper half 131a of the first longitudinal end 131 (e.g. the end of the main body 132 where one of the two opposite lateral side walls 104b is positioned) of the main body (or elongate main body) 132 of the connecting-floatation-unit 130 and an underside socket (or longitudinally-aligned-underside-socket) 144 extending inwards at a lower half 131b of the first longitudinal end 131 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130. Accordingly, either or both of the overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 and the underside socket (or longitudinally-aligned-underside-socket) 144 may respectively extend in a generally longitudinal direction, and may be parallel or at an angle with respect to a longitudinal axis of the main body (or elongate main body) 132. Further, the main body (or elongate main body) 132 of the connecting-floatation-unit 130 may include an upper-side socket (or longitudinally-aligned-upper-side-socket) 146 extending inwards at an upper half 133a of a second longitudinal end 133 (e.g. the end of the main body 132 where another of the two opposite lateral side walls 104b is positioned) of the main body (or elongate main body) 132 of the connecting-floatation-unit 130 and a foot protrusion (or longitudinally-directed-foot-protrusion) 148 extending longitudinally from a lower half 133b of the second longitudinal end 133 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130. Accordingly, either or both of the upper-side socket (or longitudinally-aligned-upper-side-socket) 146 and the foot protrusion (or longitudinally-directed-foot-protrusion) 148 may respectively extend in a generally longitudinal direction, and may be parallel or at an angle with respect to the longitudinal axis of the main body (or elongate main body) 132. The underside socket (or longitudinally-aligned-underside-socket) 144 at the first longitudinal end 131 is shaped to correspond with a shape of the foot protrusion (or longitudinally-directed-foot-protrusion) 148 at the second longitudinal end 133, and the upper-side socket (or longitudinally-aligned-upper-side-socket) 146 at the second longitudinal end 133 is shaped to correspond with a shape of the overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 at the first longitudinal end 131. According to various embodiments, each of the longitudinally-directed-overhanging-protrusion 142 and the longitudinally-directed-foot-protrusion 148 may have a semi-circular-shaped tip (or rounded tip). According to various embodiments, each semi-circular-shaped tip of the longitudinally-directed-overhanging-protrusion 142 and the longitudinally-directed-foot-protrusion 148 may have a curved portion (or curved edge) directed away from the main body (or elongate main body) 132. According to various embodiments, each of the longitudinally-aligned-underside-socket 144 and the longitudinally-aligned-upper-side-socket 146 may be shaped to correspond exactly to that of the longitudinally-directed-overhanging-protrusion 142 and the longitudinally-directed-foot-protrusion 148.

[0109] According to various embodiments, two connecting-floatation-units 130 may be joined end to end in a manner whereby the overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 at the first longitudinal end 131 of a first of the two connecting-floatation-units 130 may be fitted into the upper-side socket (or longitudinally-aligned-upper-side-socket) 146 at the second longitudinal end 133 of a second of the two connecting-floating-units 130, or the foot protrusion (or longitudinally-directed-foot-protrusion) 148 at the second longitudinal end 133 of the second of the two connecting-floating-units 130 may be fitted into the underside socket (or longitudinally-aligned-underside-socket) 144 at the first longitudinal end 131 of the first of the two connecting-floatation-units 130. Accordingly, the first longitudinal end 131 and the second longitudinal end 133 of each of the two connecting-floatation-units 130 may be configured to be jigsaw-like such that the two connecting-floatation-units 130 may be joined end to end in a manner resembling the joining of two jigsaw pieces together.

[0110] Referring to FIGS. 4A, 4C and 4D, at the first longitudinal end 131 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130, a downward facing surface 142a of the overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 may transit upwards (e.g. with respect to the flat base 134) to a downward facing surface 144a of the underside socket (or longitudinally-aligned-underside-socket) 144 so as to define a step profile 143 along the transition thereof. Further, at the second longitudinal end 133 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130, an upward facing surface 148a of the foot protrusion (or longitudinally-directed-foot-protrusion) 148 may transit downwards to an upward facing surface 146a of the upper-side socket (or longitudinally-aligned-upper-side-socket) 146 so as to define a step profile 147 along the transition thereof. According to various embodiments, the step profile 143 between the overhanging protrusion (or longitudinally-directed-overhanging-protrusion) 142 and the underside socket (or longitudinally-aligned-underside-socket) 144 at the first longitudinal end 131 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130 may form a first interlocking portion of the connecting-floatation-unit 130, and the step profile 147 between the foot protrusion (or longitudinally-directed-foot-protrusion) 148 and the upper-side socket (or longitudinally-aligned-upper-side-socket) 146 at the second longitudinal end 133 of the main body (or elongate main body) 132 of the connecting-floatation-unit 130 may form a second interlocking portion of the connecting-floatation-unit 130. Accordingly, when the first longitudinal end 131 of a first connecting-floatation-unit 130 is joined to the second longitudinal end 133 of a second connecting-floatation-unit 130, the first interlocking portion (or the step profile 143 between the overhanging protrusion 142 and the underside socket 144) of the first connecting-floatation-unit 130 may interlock or engage with the second interlocking portion (or the step profile 147 between the foot protrusion 148 and the upper-side socket 146) of the second connecting-floatation-unit 130.

[0111] According to various embodiments, the first and second interlocking portions of the connecting-floatation-unit 130 may allow two or more connecting-floatation-units 130 to be pre-aligned and held in position before the respective connection portions (or corner-connection-portions) 136 may be joined together to form the connection joint 150.
