Detailed Description of the Preferred Embodiments [0160] An example of a pontoon will now be described in more detail with reference to Figures 1A to 1H. [0161] In this example, the pontoon includes a frame 110, having a whaler 120 extending around at least part of a perimeter of the frame 110. A skirt 130, including a number of skirt floats, is mounted on an underside of the frame 110, the skirt floats extending around at least part of a perimeter of the pontoon mounted on the underside of the frame 110. In one example the skirt includes a number of different types of skirt float 131, 132, 133 as will be described in more detail below. A fender 140 is coupled to the whaler 120, with the fender H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 14 extending around the part of the perimeter of the pontoon 100, outwardly of the whaler 130. A deck 150 is mounted on an upper side of the frame 110, although alternatively, the deck could be a precast slab or insitu concrete deck. [0162] In use, the skirt floats operate to provide buoyancy to the pontoon 100 thereby allowing the pontoon to float. In this example, the skirt 130 extends around only half of the perimeter of the pontoon in which case the other end of the pontoon would typically be supported in some other manner. Normally however the skirt 130 extends around the entire perimeter of the pontoon to keep the pontoon afloat. [0163] In use, the pontoon 100 can be simply constructed by providing the frame 110, coupling the whaler 120 to the frame, mounting the skirt floats to the frame, coupling the fender 140 to the whaler 120 and providing the deck 150. This allows the apparatus to be constructed on site by sending the component parts to the site thereby making the transport and construction of the pontoon relatively straightforward. It will be appreciated that this allows for a simple set of instructions to be used to enable dealers to assemble the flat packed kit from a container, thereby reducing reliance on skilled labour. [0164] Further details of the arrangement will now be described with further reference to Figures 2 to 12. [0165] Typically, the frame 110 is formed from a lattice including interconnected lateral and longitudinal frame members 111, 112, examples of which are shown in more detail in Figures 2A and 2B, respectively. The frame members 111, 112 are typically formed from extrusions of a suitable material, such as aluminium or the like, with the lateral frame members 111 typically including a substantially rectangular cross section, whist the longitudinal frame members 112 have an upturned U-shaped cross section with the longitudinal frame members 112 being connected to an underside of the lateral frame members 111 utilising a fastener such as a Huck bolt or the like. [0166] The roles of these frame members 111, 112 may be reversed with the longitudinal frame members having a rectangular cross section and the lateral frame members having a U shaped cross section, the lateral frame members being attached to an underside of the longitudinal frame members. It will also be appreciated that this arrangement is not intended H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 15 to be limiting and that different configurations of frame members can be used to construct a similar lattice arrangement. [0167] However, the use of rectangular and upturned U-shaped frame members allows these to be easily connected using bolts whilst providing sufficient structural rigidity of the frame yet maintaining a light weight construction. This is particularly advantageous in the case of floating pontoons as it minimises the pontoon weight whilst ensuring sufficient structural rigidity in use. Furthermore, this allows the lattice frame 110 to be constructed onsite from individual members which are then simply bolted together, thereby avoiding the need to transport a constructed frame to site, as well as allowing the frame to be constructed easily, avoiding the need for welding, cranes for lifting, or the like. [0168] An example of a whaler is shown in more detail in Figures 3A and 3B. In this example, the whaler includes an elongate whaler body 310, typically formed from an aluminium extrusions, having an L-shaped cross section with a box section 311 provided on an inner corner of the L-shape. The box section may also include a diagonal member 312 to provide additional structural rotundity. [0169] The whaler includes parallel spaced apart flanges 313, 314 extending from the box section 311 to define a frame mounting channel 315, which in use receives ends of the lateral frame members 111 (or longitudinal frame members depending on the configuration) of the frame 110 in use. The frame members may be held in place using Huck bolts or the like extending through the flanges 313, 314. [0170] In use, the deck 150 is typically provided on the frame 110 with at least part of the upper flange 313 positioned between the deck 150 and the frame 110, as will be described in more detail below. [0171] The whaler also typically includes one or more (two in this example) T-shaped upper connector channels 321, 322 which extend longitudinally along an upper surface 316 of the whaler 120, the upper surface channels 321, 322 being for receiving an accessory connector. This can be any form of accessories such as a fence, a cleat, a gangway, furniture shade device, such as an umbrella, or the like.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 -16 [0172] The whaler also includes at least one T-shaped outer channel 323 extending longitudinally along an outer surface 317 of the whaler, the outer channel being for receiving a pontoon connector. In one example, the pontoon connector is in the form of an elastomeric hinge, or similar, which can engage with the outer channels 323 on adjacent pontoons, thereby allowing the pontoons to be interconnected, whilst further allowing for relative movement of the pontoon, for example to accommodate wave action or the like. However, other connection mechanisms can be used. [0173] The whaler 120 may also include at least one lighting strip channel (not shown) mounted to the outer surface 317, that in use houses a lighting strip including a plurality of light sources, such as LEDs (Light Emitting Diodes) or the like, adapted to provide illumination around the pontoon, thereby assisting in locating the pontoon in low ambient light levels, for example to assist with docking. [0174] The whaler further includes spaced apart fender mountings 331, 332 extending longitudinally along the outer surface 317 of the whaler, allowing the fender 140 to be connected thereto. The fender mountings 331, 332 are typically in the form of parallel spaced part flanges 331.1, 331.3, 332.1, 332.2 extending substantially perpendicularly from the whaler outer surface 317, and including teeth for engaging the fender in use. [0175] For a rectangular pontoon, four whaler bodies 310 are provided, each extending along a respective edge of the pontoon, with corner pieces 340 shown in Figures 3C and 3D, being used to interconnect the ends of the whaler bodies. The corner pieces have a similar overall cross section to the whaler, albeit with only one T-shaped upper channel 341, and two fender spaced apart mountings 342, 343, which allow the fender 140 to extend around the corner pieces 340. The corner pieces may also include a rubber bumper 344 positioned between the fender mountings 342, 343, for absorbing impacts on the corners. The corner piece also typically includes mounting lugs 345 for receiving a fastener such as a Huck bolt, for coupling to the whaler body 310. [0176] As mentioned above, the skirt 130 typically includes a number of skirt floats. In one example, the skirt includes corner floats 131, and first and second edge floats 132, 133. [0177] An example of a skirt corner float 131 is shown in Figures 4A to 4C.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 17 [0178] In this example, the skirt corner float 131 includes a skirt corner float body 410 having a substantially cuboid configuration, and including a base 411 and an upper surface 412 interconnected via side walls 413. The skirt corner float body 410 is typically hollow and filled with air or a buoyant material to thereby provide buoyancy, with the body being formed from a moulded plastic, or the like. [0179] The skirt corner float 410 includes an opening 421 extending through the skirt corner float body 410, with the opening being fluted towards the base 411 and including a recess 422 near the upper surface 412. [0180] In use, the opening is utilised to allow a securing member 430 to be received therein for securing the pontoon in position. Whilst this could include a pile or the like, in one example the securing member is a flexible securing member, such as a rope 431, Sea Flex system, chain, or the like, which is attached at one end to a water body bottom and the other end to a lug 432 retained in the recess 422, allowing the securing member to be retained in position. In use, the securing members 430 are typically arranged in a cross wise fashion, with the fluting helping to accommodate lateral loads on the pontoon 100. An example of this will be described in more detail below. [0181] The skirt corner float body 410 also typically includes at least one channel 414 in an upper surface 412 that receives frame members of the frame when the floats are coupled to the frame 110, and may optionally include at least one mounting lug (not shown) extending from the upper surface 412, the mounting lug receiving a fastener for coupling to the frame in use. The corner float body 410 can further include a corner lip 515, projecting upwardly from the upper surface 412, for receiving the whaler corner piece 340, and edge lips 416 extending upwardly from outer edges of the corner float body 410, for supporting the whaler 310. [0182] The skirt corner float body 410 is also designed to allow stacking of the float, by 1800 rotation and inversion, for maximum packing efficiency during transport. [0183] The skirt 130 typically includes first and second skirt edge floats 132, 133, examples of which are shown in Figures 5A to 5D and 6A to 6C, respectively.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 18 [0184] The first skirts edge floats 132 include a float body 510 having a generally cuboid shape and enclosing an internal cavity which may be filled with air or a buoyant material to thereby provide buoyancy, or with ballast, as required. [0185] The body includes channels 511 and edge rebates 512 defined by platforms 513.1 in an upper surface 513, the channels 511 and edge rebates 512 being for receiving the frame members 111, 112, whilst the platform regions 513.1 can engage an underside of the whaler 120 depending on the orientation of the skirt edge float. At least one mounting lug 514 extending perpendicularly from the upper surface 513 is provided for receiving a fastener, such as a Huck bolt or the like, for allowing the skirts edge floats 132 to be coupled to the frame 110 in use. Similar connecting means could also be used for longitudinal frame members although this is not essential. [0100] In addition, the skirt edge float 132 may include grooves 515 extending along the upper surface 513 and down a side wall 516 of the float, to allow for drainage of water from an upper surface of the float. [0101] The floats may also include channels 517 that extend through the float between float side walls 516, towards a base 518 of the float. In use, the channels 516 receive a rope or other similar member, which can be inserted into the channel 516 via a gap 519. The rope passes through all the skirt floats and can be tensioned to thereby provide for additional securement of the skirt floats. [0102] In a further example, a pillow float 520 having a pillow float body 521, shown in Figures 5E and 5F can be mounted on an underside of the skirt edge float 132, as shown in Figures 5G and 5H. The pillow float 520 and skirt edge float 132 cooperate to define cylindrical channels 522 that can receive up to three cylindrical bodies, such as standard 225mm diameter PVC pipes, that can provide additional buoyancy or additional ballast, as required. [0103] An example of a second skirt edge float is shown in Figures 6A to 6C. This has a generally similar configuration to half of the float of Figures 5A to 5D.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 19 [0104] In this example, the second skirt edge float 133 includes a float body 610 having a generally cuboid shape and enclosing an internal cavity which may be filled with air or a buoyant material to thereby provide buoyancy, or with ballast, as required. The body includes edge rebates 612 in an upper surface 613 for receiving the lateral frame members 111, mounting lugs 614 extending perpendicularly from the upper surface 613, the mounting lug being for receiving a fastener, such as a Huck bolt or the like, for allowing the skirts edge floats 133 to be coupled to the frame 110 in use. A platform 613.1 can be used for engaging an underside of the whaler 120. [0105] In addition, the skirt edge float 133 may include grooves 615 extending along the upper surface 613 and down a side wall 616 of the float, to allow for drainage of water from an upper surface of the float. The floats may also include channels 617 that extend through the float between float side walls 616, towards the base 618 to allow for additional securement of the skirt floats, as described above. [0106] It will be appreciated however, that the second skirt edge float 133 will provide a reduced amount of buoyancy, and that the first and second skirt edge floats 132, 133 can therefore be used interchangeably depending on the amount of buoyancy required. As shown further shown in Figure ID, the first and second skirt edged floats 132, 133 can be interspersed and yet provide a continuous outer surface when arranged on the pontoon so that the use of different skirt edge floats is not apparent when the pontoon is in use. [0107] A first example of a fender 140 will now be described with reference to Figure 7A. [0108] In particular, the fender 140 is typically formed from a longitudinal U-shaped deformable fender body 710 including whaler connectors 711, 712 provided on ends of the U-shape, the whaler connectors being for engaging the fender mountings 331, 332 of the whaler 120 of Figures 3A and 3B. In one example, the whaler connectors 711, 712 include teeth, for cooperating with corresponding teeth in the fender mountings 331, 332, thereby assisting to secure the fender in position. [0109] The fender body 710 defines a void 713 between the fender 140 and the whaler 120, allowing for deformation of the fender body to thereby at least partially absorb impacts, as well as allowing any pontoon connector to be accommodated therein. The fender 140 also H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 20 includes a flange 720 defining a second open void 721 positioned outwardly of the void 713, allowing for deformation of the flange 720 to thereby at least partially absorb impacts. The flange 720 may include cut-outs 722 for aiding deformation of the flange. [0110] Recesses 714 can be provided on the fender body 710, providing a location for the fender to be impacted with a tool, such as a hammer, during a mounting process and in particular to assist in coupling the fender 720 to the fender mountings 331, 332. [0111] The fender body 710 can also include a shroud 715 that extends downwardly from the fender body to shield the lighting strip mounted to the whaler, thereby providing down light illumination around the pontoon. [0112] A second example of a fender will now be described with reference to Figure 7B. In this example, the fender 140.1 is adapted for use with a modified whaler body 310.1 in which the upper fender mounting 331 is replaced by a fender mounting 361, which includes a lip 362 extending generally parallel to the outer surface 317 of the whaler body 310.1. [0113] In this example, the fender 140.1 includes a longitudinal deformable fender body 760 including whaler connectors 762, 766 that in use connect to spaced apart fender mountings 361, 332, extending longitudinally along an outer surface of the whaler body 310.1. The fender body 760 is curved in use to define a void 763 between the fender 140.1 and the whaler body 310.1, allowing for deformation of the fender body 760 to thereby at least partially absorb impacts, as well as to allow services and/or pontoon connectors to be accommodated therein. [0114] It will therefore be appreciated that this functions in a broadly similar manner to the first example fender 140. However, in this example, the body 760 is generally transported in a flat or rolled up configuration, rather than being U-shaped. In this instance, the fender body 360 includes a cut-out 761, extending substantially mid-way along the length of the fender body 760, allowing the fender body 760 to be bent into a V-shape, as shown by the arrow 380. The use of a V-shape as opposed to a U-shape can be beneficial in reduce the contact area when vessels impinge against the fender.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 21 [0115] In this example, the whaler connector 762 is broadly similar to the whaler connectors of the previous example. However, the upper whaler connector 766 is in the form of lipped edge that engages with the lip 362 of the fender mounting 361. As in the previous example, the fender body 760 includes a recess 764 for impact with a tool during a mounting process, so that the whaler connector 762 can be easily inserted into the fender mounting 332. Once this has been completed, the fender body 760 is bent as described above, allowing the whaler connector 766 to engage the fender mounting 361, as shown in Figure 7B. The whaler connector 762 can then be retained in position using a plug 767, which acts to wedge the whaler connector 766 in position, thereby securing the fender in place and making installation of the fender easier. [0116] The fender 140.1 includes a shroud 765 that extends downwardly from the fender body to shield a lighting strip mounted in a lighting strip channel 370 of the whaler body 310.1. [0117] As in the previous example, the fender 140.1 can be adapted to have an initial soft touch to impact, with a second stage in which another element then engages to increase resistance to impact. This prevents damage to vessels during initial impact, whilst still providing sufficient overall impact resistance. [0118] In one example, the fender 140, 1401.1 is made of a thermoplastic elastomer (TPE), which typically have good shape memory properties. In one particular example, the fender is made of Santoprene m , which is a mixture of in-situ cross linked EPDM (ethylene propylene diene monomer (M-class) rubber) rubber and polypropylene, although other suitable materials could be used. This material also has a low coefficient of friction, meaning salt water tends to run-off thereby reducing salt crystallisation on the fender surface. [0119] It will also be appreciated that other arrangements of fender could be used and a further example is shown in Figure 7C. In this example, the fender 140.2 includes a fender body 790 having connectors 791, 792 at each end for connecting to the whaler. The fender body includes curved sections 793, 794, allowing the fender to deform and accommodate impacts in a manner similar to that previously described. In this example, the curved sections H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 -22 793, 794 could be adapted to deform with different applied forces, to thereby allow for progressive deformation. [0120] In use, the deck 150 includes a substantially planar deck body, which in use is mounted on the frame 110, with the upper flange 353 sandwiched between the deck 150 and frame 110. [0121] In use, deck edge strips are used to overlay the deck. A deck corner strip 801, having a quarter quadrant of an annular shape and two connector flanges 802, with mounting clips 803, is shown in Figure 8A. In use, the connector flanges 802 are inserted in the upper channel 341 of the corner piece 340, with the clips 803 engaging holes in the channel 341 to engage the deck corner strip 801 with the whaler corner piece 340. [0122] A deck edge strip 811 shown in Figure 8B, includes an elongate body having a hooked flange 812 and groove 813 on one side, and a spaced apart stop 814. In use, the hooked flange 812 and groove 813 engage an outer edge of the upper channel 322, with the deck being in abutment with the stop, so that the deck edge strip overlays the deck 150. [0123] An example of a cut-away view of the frame 110, the whaler 120, the fender 140, the skirt 130 and the deck edge strip 811 is shown in Figure 9. It will be appreciated that this will vary depending on the particular configuration of whaler 120, fender 140, or the like. [0124] An example of a cleat for mounting to the pontoon will now be described with reference to Figures 1OA to 1OD. [0125] In this example, the cleat 1000 includes a planar base 1010 having feet 1011 and a connector 1012. In use the feet 1011 and connector 1012 engage the first and second upper connector channels 321, 322 of the whaler 120, thereby allowing the cleat to be retained on the pontoon. The cleat 1000 further includes a winged body 1020 coupled to the base 1010, allowing a rope to be secured thereto, for example for mooring purposes. [0126] An example of a gangway for pontoon access will now be described with reference to Figures 1IA to 1IC.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 23 [0127] In this example, the gangway 1100 includes a deck 1110, a base 1120 spaced apart from the deck 1100 and side walls 1130 interconnecting the base 1120 and deck 1110, to thereby define a cavity 1111 that in use can contain services, such as waste/water pipes, electrical cabling or the like. [0128] In one example, the gangway can be transported in a disassembled configuration, allowing this to be assembled on site. In one example, to assist with this, the side walls include a number of side wall panels 1131 and optionally side wall end panels 1132, which can be connected to the deck 1110 and base 1120 on site. The side walls 1130 can include lighting strip channels 1133, which in use contain lighting strips for providing down-light illumination. The side walls 1130 may also support hand rails 1134, and include apertures for aesthetic purposes, as well as to allow airflow for reducing laterals loads in use. [0129] Typically the gangway includes a shore connector (not shown) for coupling the gangway to the shore and may be pivotally mounted to the whaler via a pontoon connector that engages a channel on the whaler. [0130] It will be appreciated that in this example, the gangway is coupled substantially to an edge of the pontoon, with the shore mounting accommodating relative movement of the pontoon and shore, thereby minimising wasted space on the pontoon. [0131] An example of a second gangway for pontoon access is shown in Figures 1 ID to 1 IF. [0132] In this example, the gangway 1150 includes a frame 1160, a deck 1170 and side walls 1180. The frame typically includes elongate central and side beams 1161, 1162 running along the length of an underside of the deck, with the central beam 1161 being offset from the deck and coupled to the side beams 1162 using bracing members 1163. It will be appreciated that this triangulated configuration provides structural support, and also allows services to be located between the frame 1160 and an underside of the deck 1170. In this example, the side walls 1180 are formed from a number of glass panels 1181 for visual appeal. [0133] Finally, a platform 1190 is hingably connected to one end of the gangway, allowing this to be coupled to the shore. In this regard, the gangway allows for a flexible coupling to H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 24 enable the pontoon to be supported from the land based mooring block that is connected to the start of the gangway. It will be appreciated that this can be used instead of stainless steel wires used to provide support the pontoon from swaying and breaking the gangway. This design can use the subsea mooring tubes to place a tether underwater to stay the unit in place. [0134] An example of a pod will now be described with reference to Figures 12A to 12D. [0135] In this example, the pod 1200 includes a base 1201, side walls 1202, and a top 1203, defining a pod cavity 1204. In one example, the top 1203 can include a removable lid 1205 to provide access to the cavity 1204, which in use can contain ballast or buoyancy, to assist with providing the required overall buoyancy for the pontoon. This allows the cavity pods to be used to add buoyancy or ballast to selected points on the pontoon, for example to accommodate uneven load distribution. In another example, the lid can be accessed via a door in the deck, such as a trapdoor, allowing the cavity to act as a storage vessel. [0136] The pod 1200 includes a number of mounting lugs 1206 and rebates 1207, for coupling the float to the frame 110 in a manner similar to that described above with respect to the skirt floats. In one example, the cavity pod is mounted on the underside of the frame but alternatively may be mounted to an upper side of the frame 110, with the pod extending through the frame 110, depending on the ballast or buoyancy requirements. [0137] As shown in Figure 12E, the pods can be provided in a range of different sizes, depending for example on buoyancy and/or ballast requirements. In one example, different colour coding can be used for pods with different levels of ballast/buoyancy, and/or different sizes, thereby assisting during construction. [0138] Accordingly, the above described arrangement provides a pontoon formed from a lattice frame, a whaler extending around a perimeter of the frame, skirt floats for providing buoyancy, a fender for impact protection and a deck. The arrangement can be transported as individual components, and rapidly and easily constructed onsite, making the arrangement cheap to deploy. The system can be made in a variety of sizes, and use different float configurations to provide required degrees of buoyancy to thereby suit a wide variety of uses.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 -25 [0139] The whaler includes a number of connector channels, allowing accessories to be coupled thereto, including cleats, gangways, fences, furniture, ice boxes, diving boards, ladders, power supplies, umbrellas, or the like. This enables a high degree of flexibility, whilst ensuring that accessories are secured to the whaler and hence to the structure of the pontoon, meaning they can be retained in place in a wide variety of conditions. This helps provide a highly flexible arrangement, allowing the pontoon to be employed in a wide variety of situations, including for mooring of craft or leisure purposes, for example to provide a floating living area. [0140] The gangway uses a novel coupling arrangement, which allows the gangway to be coupled directly to the whaler. This provides a strong effective coupling between the gangway and pontoon, whilst minimising the volume of the pontoon which is used for gangway securement and access. [0141] The pontoon can also include one or more pods containing a cavity, and which are coupled to an underside of the frame for providing additional buoyancy and to a top of the frame to provide additional ballast. These pods can be used to contain ballast or buoyancy, and can be provided at any location on the frame, thereby ensuring buoyancy of the pontoon is maintained, even if weight distribution on the pontoon is uneven. [0142] The pods include a removable lid, allowing ballast to be added onsite, for example using gravel, earth or other available materials sustainably gathered from the site, thereby minimising transport weight. As a further alternatively, the lid can be access via a trapdoor or the like in the deck, in which case the pods can be used for storage, for example of wet gear, or the like. [0143] An example of a modular floating structure will now be described with reference to Figures 13 to 15. [0144] In this example, the structure 1300 includes a number of elongate floats 1310 and number of hubs 1320, with four of each being shown in this example for the purpose of illustration. Each elongate float 1310 includes a hub connector at at least one end, and more typically each end, whilst the hub includes a hub body having a base, at least one side wall, and a cover to define a hub cavity. At least one slotted channel is provided in the at least one H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 26 side wall that in use receives a hub connector of the elongate float 1310, thereby allowing the elongate floats to be coupled to the hub. [0145] In use, a number of elongate floats and hubs may be used to form structures having a desired configuration. In the example of Figure 13A, four elongate floats and four hubs are interconnected in a generally square shaped configuration, and it will be appreciated that by coupling additional elongate floats to the hubs, the structure can be extended, allowing a variety of configurations to be provided. [0146] An example of an elongate float will now be described in more detail with reference to Figures 14A to 14C. [0147] In this example, each elongate float 1310 includes an elongate float body 1401 having a respective hub connector 1402 at each end. The float body is typically made of a moulded plastic, and is filled with a buoyant material, such as air, to provide buoyancy. The hub connector 1402 is formed from a generally T-shaped connector, including a plate 1411 supported spaced apart from an end surface 1403 of the float body by a stem 1412. [0148] The elongate float body 1401 also typically at least one opening 1404 extending laterally therethrough, to thereby allow water to flow through the float. This helps minimise the structural requirements for the float as well as to prevent undue stresses on the float structures causes from for example by currents, waves action or the like. The elongate float body 1001 also optionally includes ridges or grooves 1405, 1406 to assist with drainage of water from the structure. [0149] An example hub will now be described in more detail with reference to Figures 15A to 15D. [0150] As shown in the hub 1320 includes a hub body 1501, typically made of a moulded plastic, having a base 1502, four side walls 1503 and a removable cover 1504 defining a cavity 1505. The side walls 1503 include slotted channels 1511 for receiving the T-shaped connectors 1402 of the elongate floats. In particular, the plate 1411 is provided in the slotted channel 1511, with the stem 1412 extending through the slot 1512, thereby securing the elongate float to the connector.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 27 [0151] In one example, the plates 1411 are wedge shaped to allow the plate to engage the slotted channel when inserted therein, thereby helping retain the plate in position. Additionally, the cover 1504 includes stops 1506 that engage the plates 1411 to further assist in retaining the hub connectors in position. [0152] Accordingly, it will be appreciated that this provide a modular structure that can be constructed by simply removing the covers from the hubs, inserting the hub connectors into the slotted channels, and then attaching the covers to the hubs. This allows a modular structure having a variety of configurations to be easily and rapidly deployed as required. [0153] An example of a second example of a modular floating structure will now be described with reference to Figures 16 and 17A to 17C. [0154] In this example, the structure 1600 includes a number of elongate floats 1610 and number of hubs 1620, similar to the elongate floats and hubs 1310, 1320 of the example of Figure 13A. In this example however, extension floats 1630 are provided for extending the length of the elongate floats. In this regard, each extension float includes a hub connector at one end and a slotted channel at the other end for receiving the hub connector of an elongate float. [0155] Again, a number of elongate floats 1610, hubs 1620 and extension floats 1630 may be used to form structures having a desired configuration. In the example of Figure 16, twelve elongate floats and extension floats are interconnected by nine hubs in a generally square shaped configuration, but it will be appreciated alternative arrangements can be used and that this is for the purpose of illustration only. [0156] In this example, the elongate float 1610 and hub 1620 are substantially as described above with respect to Figures 14 and 15 and will not therefore be described in any further detail. [0157] An example of an extension float will now be described in more detail with reference to Figures 17A to 17C. [0158] In this example, each extension float 1630 includes an elongate float body 1701 having a respective hub connector 1702 at a first end 1703 and a slotted channel 1706 at a H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 28 second end 1705. The extension float body is typically made of a moulded plastic, and is filled with a buoyant material, such as air, to provide buoyancy. The hub connector 1702 is formed from a generally T-shaped connector, including a plate 1711 supported spaced apart from an end surface 1703 of the float body by a stem 1712. [0159] The elongate float body 1701 also typically at least one opening 1704 extending laterally therethrough, to thereby allow water to flow through the float. This helps minimise the structural requirements for the float as well as to prevent undue stresses on the float structures causes from for example by currents, waves action or the like. The elongate float body 1001 also optionally includes ridges or grooves to assist with drainage of water from the structure. [0160] The slotted channel 1706 is similar in configuration to the slotted channels of the hubs 1501, albeit with the slotted channels extending laterally, so that the channel is accessed via a side of the extension float, which is in turn covered with a cap 1707. This facilitates ease of coupling, allowing the cap 1707 to be removed and the hub connector of an elongate float to be inserted therein, whilst also providing a strong connection, as will be appreciated by persons skilled in the art. [0161] It will be appreciated that the extension floats can be used to increase the physical distance between the hubs. Whilst a similar effect could be achieved by providing an increased length of elongate float, this can limit the ability of such floats to be easily constructed (for example using standard roto-moulding machines) and transported. The use of extension floats thereby increases the degree of flexibility of the system, allowing different sizes of modular floating structure to be constructed, whilst allowing a standard size of elongate float to be used. [0162] In use, the modular floating structures 1300, 1600 can be utilised to support a variety of different components. This can include decking, for example, to provide a modular pontoon, or alternatively can include support structures for supporting equipment such as solar panels or the like. [0163] The modular floating structures can be secured relative to the shore or another structure using any appropriate technique, such as the use of pilings or the like.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 29 [0164] An example of a pile sleeve will now be described with reference to Figures 18A to 18E. In this regard, pile sleeves are typically placed over piles thereby protecting the pile from the ambient environment and hence helping to reduce corrosion. [0165] In this example, the pile sleeve 1800 includes a number, with three being shown in this example, of interconnected tubular pile sleeve bodies 1801, 1802, 1803 connected in an end to end arrangement. In use, the pile sleeve 1800 extending over the pile and having one end embedded in a pile supporting substrate. [0166] Ends of the three sleeve portions that are coupled together include complementary connectors 1806, 1807, which engage using an interference fit, butt weld, or the like. This allows the sleeve portions to be easily transported to site and then coupled together to form a sleeve having a required size. The pile sleeve portions are typically made of HDPE (high density polyethylene) or another similar material, and may be formed by roto-moulding or the like. [0167] In this example, the lower sleeve portion 1803 typically includes a serrated end, to assist with driving the pile sleeve into the pile supporting substrate. Typically the pile sleeve is embedded about Im into the mud, to thereby seal the air around the pile thereby preventing rusting of the pile. The top sleeve 1801 typically includes a cap 1805 for finishing the sleeve and sealing the sleeve and may also include a bung 1808 to allow air to escape during installation, with the bung being sealed after installation is complete. [0168] Typical pile sleeves that use HDPE water pipes have a 20mm nominal wall thickness for protection of abrasive fluids pumped inside like dredge sand etc. However, in this example, the pile sleeve is only used to prevent air impacting the pile and therefore can use a 10mm wall thickness, with ribbing being provided for additional strength. [0169] The pile sleeve also allows for colour choice, built in pile cap colour coded to match, an area for branding or directions to marina arm names. Because it is segmental in nominal 3m lengths and but welded in situ, it can significantly reduce transport and handling costs. [0170] Additionally, the pile sleeve can include inserts threaded into the surface to hold boat mooring lines up out of the water. The threads can be right through the surface to allow the H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 30 sleeve to be permanently connected to the steel pipe at the top with a setscrew. This prevent ride up which breaks the air seal by allowing the water and oxygen to become present inside the pile area. [0171] An example of a pile mounting assembly, for coupling a structure such as the pontoon or modular floating structure to the pile will now be described with reference to Figures 19A to 19D. [0172] In this example, the pile mounting assembly 1900 includes a bracket 1910 that in use is coupled to the structure. A pile mounting ring 1911 is coupled to the bracket 1910, for example using struts 1912 or other similar coupling members. The pile mounting ring 1911 has a substantially annular shape allowing the pile mounting ring 1911 to be positioned around a pile 1901 in use. The pile mounting ring 1911 supports a number of rollers 1913 that engage the pile to thereby allow longitudinal movement of the pile mounting assembly relative to the pile 1901. In one example, the rollers 1913 are held in place using roller brackets 1914 extending inwardly from an inner circumferential surface of the pile mounting ring 1911, although it will be appreciated that other arrangements may be used. [0173] The pile mounting assembly 1900 further includes at least one brush support 1920 including a brush 1924 that in use is urged against the pile 1901, to thereby clean the pile as the pile mounting assembly 1900 moves relative to the pile. In particular, this can be used to brush materials and objects from the pile surface in the vicinity of the waterline. This can assist in preventing build-up of barnacles, seaweed, algae or the like, which in turn ensures free movement of the pile assembly along the pile, as well as preventing damage to the pile. [0174] It will be appreciated that in one example, the pile 1901 may incorporate a pile sleeve similar to that described above with respect to Figures 18A to 18E, in which case the rollers 1913 and brush 1924 will engage the pile sleeve, although this is not essential. [0175] In one example, the assembly includes a brush bracket 1921 coupled to the pile mounting ring 1911, with the brush support 1920 being movably mounted to the brush bracket, for example via an arm 1922 pivotally mounted to the brush bracket 1921. A biasing mechanism 1923, such as a piston, spring or the like, can be coupled to the brush bracket 1921 for urging the brush 1924 against the pile. Although only a single brush bracket 1921 is H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 -31 shown for each brush support 1920, it will be appreciated that additional brush brackets 1921 could be used for additional stability. [0176] In the current example, it will be appreciated that the pile assembly includes two brush supports 1920, each brush support having a corresponding brush 1924. The brush supports 1920 and brushes 1924 have a substantially semi-circular shape so that the brushes 1924 substantially encircle the pile 1901, thereby ensuring cleaning occurs around the full extent of the pile. [0177] In the example of Figures 4A to 4D, a fluted opening was provided that formed part of a float of a modular pontoon, allowing the pontoon to be coupled to the water body bed using a flexible member, whilst accommodating lateral loads applied to the pontoon. It will be appreciated however, that the use of this arrangement in a modular pontoon is not limiting, that this from of arrangement could be used in any pontoon. [0178] Accordingly, in one example, a pontoon can be provided including a deck and at least one opening extending through the deck that in use receives a securing member for securing the pontoon in position, wherein the opening is fluted towards an underside of the deck and wherein the securing member is an elongate flexible member attached to a water body bottom, the fluting being designed to accommodate lateral loads exerted by the securing member. [0179] This arrangement could be achieved in any appropriate manner, and an example of a securing apparatus allowing a fluted opening to be incorporated into a variety of pontoons will now be described with reference to Figures 20A to 20E. [0180] In this example, the securing apparatus 2000 includes a first body 2010, a second body 2020 and a tubular body 2030 interconnecting the first and second bodies. In this example, the first and second bodies are provided in upper and lower sides of the pontoon deck, with the tubular body passing through the deck D so that it interconnects the first and second bodies 2010, 2020. In use, a securing member (not shown), such as a rope, chain, Sea Flex member or the like, is coupled to a bracket 2011 provided in the first body 2010, extends through the tubular body 2030 and a fluted opening 2021 of the second body 2020.

H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 -32 The securing member can then be attached to a water body bottom, with the fluting accommodating lateral loads exerted by the flexible member, as previously described. [0181] Thus a method for securing a pontoon can include providing a securing apparatus including a first body provided in an upper side of the deck D, the first body including a bracket, a second body provided in a lower side of the deck D, the second body including a fluted second body opening fluted towards an underside of the deck and a tubular body passing through the deck that interconnects the first and second bodies; and then coupling a securing member to the bracket, the securing member extending through the tubular body and the fluted opening, the securing member including a flexible member attached to a water body bottom, the fluting being designed to accommodate lateral loads exerted by the flexible member. [0182] Typically, the first body 2010 defines a cavity 2012 containing the bracket 2011 and includes a top opening 2013 to provide access to the bracket 2011 and a base opening 2014 that communicates with a tubular body opening 2031. The second body fluted opening 2021 also communicates with the tubular body opening 2031, allowing the securing member 2040 to extend therethrough. [0183] In use, the top opening 2013 could be closed using a cover 2015, or the like, which in one example can be removed using a key 2016, allowing access to the bracket. The bracket 2011 could be of any suitable form, but in one example, includes opposable jaws 2011.1 that can be urged together using bolts 2011.2, allowing the securing member 2040 to be clamped therebetween. [0184] The securing apparatus 2000 includes at least one bracing member 2040 extending between the first and second bodies, which can assist in holding the bodies in a spaced apart arrangement during construction of the pontoon and/or post constructions, for example to help distribute loads so they are not wholly accommodated by the tubular body alone. [0185] Additionally and/or alternatively, the securing apparatus 2000 can include a sleeve 2050 is provided outwardly of the tubular body. In use the sleeve 2050 can be embedded within the deck, for example during construction, with the first, second and tubular bodies 210, 220, 230 being inserted therein during a later stage of construction. This is particularly H:\tw\Interwoven\NRPortbl\DCC\TW\6527026_1.doc-24/10/2011 - 33 the case with pontoon decks made of concrete, when the sleeve is provided within the concrete, allowing the concrete to set, with the first, second and tubular bodies 210, 220, 230 then being fitted and further concrete and optional reinforcement, such as rebar or the like, provided between the sleeve 2060 and tubular body 2030. However, it will be appreciated that this is not essential, and alternatively the tubular body and/or first and second bodies can be embedded directly within the concrete. [0186] Thus, when manufacturing a pontoon including a securing apparatus, this method can include embedding a sleeve in the pontoon deck, providing the tubular body within the sleeve and coupling the first and second bodies to ends of the tubular body. Alternatively, this can include embedding the tubular body directly within in the pontoon deck and coupling the first and second bodies to ends of the tubular body. [0187] It will also be appreciated that whilst the use of a separate securing apparatus is described, this is not essential and alternatively, the fluted opening through the pontoon could be provided using suitable configuration of the pontoon body, for example using moulding of concrete or other materials. The use of a separate securing apparatus is however beneficial as this allows the fluted opening to be more easily created, with an integrated bracket for the securing member, as well as allowing for this to be made of a durable material, such as high density polymer or the like, which is able to withstand weathering as well as repeated stressing and wear from the securing members. [0188] Throughout this specification and claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers or steps but not the exclusion of any other integer or group of integers. [0189] Persons skilled in the art will appreciate that numerous variations and modifications will become apparent. All such variations and modifications which become apparent to persons skilled in the art, should be considered to fall within the spirit and scope that the invention broadly appearing before described.
