The mp ra y mooring device is reusable, it can be mounted in different locations and has a minisiusi impact on. t squatlc environment

{X¾4> Since the mooring device is suitable for use in a. body of water, the meoring dev ce ma fee: used, to moor an entity in region or environment that is associated witfe, adjacent or borders the body of water.

The Pile

(125) The mooring device c ® ises a pile M) .■ The pile serve? as an. anpbor to at; least s bs anfci lly maintain the: location or the mggring device in the body of: water,

(1265 The pile is configured to be embedded, in th floor supporting a body of water. The pile may be configured o be permanently embedded in the floor for an unlimited period of time. Alternatively, the pile may fee: configured to foe he^o^abiy embedded in the floor so that v.he mooring devrce c r- be temporarily st cs& &d to e floor when it is required and then e v d hen it is no longer necessary.

(12? ) e pile m comprise a shaft: ia) h vin leading end (lb) and a trailing end (ley.

C128) the longitudinal axis Μ) o€ the pile extends along the shaft from the leading end to the trailing end. The ile: may b embedded in the floor at an an-gle with respect to a vertical axis. However , to minimise the loads acting on th pile d ring installation, the pi ie is preferably embedded in the floor sudh tha the longitudinal axis ox the pile exte ds syhstanfially parallel to vertic l axis,

(1295 The ile may comprise tip (Id) formed at the leadin end: of the: shaft. The ti helps the pile t penetrate, the floor.

(130) The shaft may have, a substantiall uniform diarse er or it. may taper outwardly from the tip towards the trailing end.

(131} When the pile is embedded i the floor,, the leading end of the ahaft extends into the floor to a certai depth whilst the portion of the trailing end the shaft protrudes above the floor.

{1.32} The pile may comprise a stop plate (le) arranged on the shaft at a predsterfnined distance from: t e leading end of the shaft. The stop plate is provided to indicate the optimum or maximum length of: shaft that should be embedded is the floor to provide a sufficient anchoring effect.. In use, the pile is preferably e bedded to a depth such that the sto

_. plate abuts a surface of the floor and a portion of the trailing end of the: pile protrpdes above the :ftoer» H^nce,. the joint does: not become embedded in the flp&r.

U33) The pile may- com rise _: acre portion, The screw- portion may comprise- a continuous helix it-hr d) e tetding: a o g at least a par o the shaft. The screw po tier; may comprise: on op more helical plates (If) s q entially arranged along the shaft. Th pil may additionally o alternatively comprise a wing ooxtipnt e wing portio may comprise one or mo e wings, ¾hcn the wing por on is arranged on the shaft, the one or more wings are configured to oj c : racially from the shaft. The wing: portion may be configured to interconnect the. .piles of two o more.- mooring devices. The .screw portion anc/oi wing portio aids the: anchoring of the pile in the floor- The sc e portio end/or wing portion ma be securely or removably mounted on the, shaft. ilM The pile may foe orc d f om any ^, material that has sufficient st uctu l integrity to withstand the loads applied: as the pile is being ^' installed or when it is aheddsd. for example, the: shaft s¾y be formed from _: steel, fibreglsas or basalt fibre.

A'1,3.3) The configuratio of: the pile is dependent on the: intended use of the .mooring: device., the permanence or temporary atu e o£ ^: the mooring dd-viea, angle at which the pile is embedde in t e f l oor , the sise, sha e, weight and type of the entity being oo cd the type: of floor materiel, the depth of the body of water, wave height and/or tidal range:. The ehaft length may range f om approxi atel 1m to Ss he shaft diameter may range om ^' ..approximately 3cm to 30cm, The screw portion diameter may range from- 10cm. to. 60cm, The wing portion ma ext nd, radially by approximately IfJctt to :6¾dmv $6- provide a sufficient anchoring effect in the floor, the pile, ssay have a i lm shaft l ngth to shaft diameter ratio. hen, the pile is intended to be em edded is clay the emb dd d shaft length is a rninimsim length of lis and the e¾bedbed shaft length to sGxew diameter ratio y be: at least 3:1, Ά pile :suitable fo being embedded is sands may hav a minimum em edded shaft length of Im and ah embedded shaf length to: screw diameter ratio of at least 6:1,

{136/ The Pile has high anchoring, effect ta -'weight ratio, i also oe a high anchoring effect to sis ratio, Henceo the pile has a lower, weigh and is more compact than the anchors of conventional mooring systems. he pile is therefore subsequently cheaper and easier t,o manufacture, transpor and install, The pile also .has limited environmental impact on the aquatic environment.

(137 Due to the s pe or anchoring effec of the pile, the pile- is shi able fox .anchorihg the flee i .device n. a range of different floor materi ls., some of which are: unsuitabl for use wit conventional moo ing systems. For example, the pile is able to provid sufficient anchorage in s^&h&6 soi 1, clay, sandy loam or sand, silt o .mud. The pile is able to provide sufficient anchorage in saturated soils, such, as sof water saturated soils,

(143) he at leas one a: s; m&y have a fixed (unchanging) conf guration. Alternatively,, the shaft may have a variable (adjustable) configuration, for ex mple, the at leeist one arm may be telescopic so that th length of the arm can change. The length of the a least; one arm ssay be adapted in different depths of water and/or changing depths of ¾ater. The at least one telescopic arm may be xatraeted t a siniaus length eg that t;h.e _: mooring device can be stored ^' and/or transported more easily. The at least o _: ne teieaeopic arm ma be extended to a maximum length so that the mooring device can be unted more easily. The at least, one arm may comprise multipl jointed portions: sp that th sha of the arm can change, The shape of the at: le st on& am may be adapted during the storing, transportation, installation, and/or us of the mooring device .

(144) The at leas one arm is coupled t . the pile by one joint ¾3 . The joint is preferably arranged between the first end of the at least one arm and: he: trailing end of the pile. Hence, when the mooring device, is mounted, in a body of water, the at least one arm extends away from the trailing end of the pile through the body of water. If the joint is unlocked, then the at least one arm. can be rotated with respect to the pile:. I the joint is locked, then the at least one arm has a fixed orientation with respect to the pile and the mooting device has a rigid structure,

(145) Mounting the joint at the bottom end of the at least one arm maximises the length of arm that may be rotated by th jsotion of the movin body of water and therefore helps to maximise the transfer of energy from the moving body of water to any energy absorption devices or energy conversio devices,, (1,46· a¾ at least one ar m y toe floatable (b oyant) in the tody o water . As a result, the arm" hah he suspended in the body of water without: sinking.

Fo :example the e gaging means ma comprise a recessed channel formed in the least one arm that is shaped, to receive a complimentary protruding portion of the at least on entity. The at least one entit ®ay then be siidably mounted o the at least one arm by sliding the protruding porti along the channel . (ISO} The engagin means rsa be configured to e mane ly e gag the at least one entity. mt na ively, the: engaging mean.a ma be configured to r»ie®ssfoiy eegsfp the at l ^ one entity. n-c;e, this advantageously llows: the at leas one entity to be released from the mooring device when mooring is ftO: lodger reg ire and it llo s the moor ng device to ¾ ^: a ange; p differen entities,

1151} The engaging: i¾ ns may oe configured tb rigidly engage the at least, one entit so that the at least one entity is unable to move relative to the arrt, Alternatively, the e g ging means may fee configured to f eely engage: the at least one entity. For ex riip e, i the mooring device is to be i corpora e in a tidal or wa e energy harnessing system, the; engaging means is preferabl configured to rigidly engag th at- least one entity so grs ^' to mximise the transfer of energ from a: m vi body of water 10 the energy harnessing syste via t e at i ae one arm.

If the at least one arm is :bo©yant _f th joint m allow the at least one arm to rotate so that it xtends from the pile is an upwardly direction towa ds the s .ri. of the foody of water, The joint may allow the at leas one arm to rotat until he a least one snn has an orientation where it can engag the entity located in. or above the body of water. The joint may allow the at, least one sa to rotate so that at least one entity coupled to the axis can have a particular orientation i the body of wate > For esaWi ie, the joint may allow the at least one a m to rotate so the at least one entity can foe arranged at a particular height above the floor,, at or neac the surface of the foody of water or within, the body of water. The joint may allow the at least one arm to rotate so that the entity is arranged or tan extend in a particular direction .rel tive: to the flow of the body of water.-

CiSSj ¾h n the mooring device is mounted -in a body of water, the joint may allow the at least one arm t rotate under the acfcion of the body of water so that the orientation of the arm can change in accordance with the water conditions. The joint ma allow the arm to ot t so: tha the height to. which the m extends may var i accordance with the depth of the food of water, e joint may allow the ar to rotate so that the direction in which the arm extends from the pile ma vary In accordance with the direction of flow.

The pil (1) of the moorina device is embed ed i the floor (F) supporting the body of water {¾?} ^' . Engaging means 12ύ arranged at the second end of the arm (25 rigidly couple the floatable member t the mooring device. The mooring device s: configured to mount the floatable member at o near the surface of the body of water. The joint ) of the moorin device allows the arm to rotate in a vertical plane so that the height of the arm (and therefore the floatable member) can change. The joint allows the. arm to rotate in a vertical plane so that the floatable member can be floated i different depths of water and can continue to float or or nea the serface of the body of water as th depth of water changes. The joint ma also allow' the arm to rotate in a horizontal plane so that the direction of the arm (and therefore the floatable; member) can change. To help maximis the absorption o the energy and deflection of the waves, the joint may also allow the arm to .r tate in a horizontal plane so that the arms extends in the direction of flow CfrOK} and a deflecting surface 0} o the floatable m rger is aligned substantially parallel to the wave crests.

In this ex le, the barrier meant is a rigid, solid panel extending between a first mooting device i¾i} and a second mooring device ( ) . As the bod of moving water collides: -with a. deflecting surface {D} of the barrier means kinetic energy is transferred; from the water to the barrier means. The deflecting surface of the harrier shears also: deflects or inhibits the flow of the moving wate (FLOW) .

The piles U.) of the mooring devices are embedded in the floor (Γ) , En aging means (2d| at the secon ends of the arms {% ^' . couple th floatable means to the mo ring devices. The joint (3) of each mooring device allows the arms and therefor® the barrier m a s anol floatable means t rotate in a vertical plane in the body of wafer unde the colliding action Of the moving body of water.. The rotation, of the barrier means and fipatapie means is indicative of the absorption of energ from, the moving body of water, The joint of each mooring device allows the arms to rotate in a vertical pier*©: during use so that they can rise and fall in accordance with the depth of th foody of water. ?hus _:/ the height of the breakwater relative to the floor varies in a reciprocating fashion due to the oscillating tidal and/or wave motion. The joint of each mooring device may also allow the arms to rotat in a horizontal plane so that they are always orientated in the direction of th flow. Hence, the deflecting surface o the barrier means is always aligned substantially perpendicula to the direction of flow so as to maximise the absorption of energy and deflection of flow.

(234) Figures 17a and 17b depict an example of a deformable breakwater device comptising a deformabie barrier means (BE) and a floatable member (B) - The barrier means comprises a plurality o rigid panels that are configured to form cuboid.

(236) The floatable means helps to resist the overturning forces of the moving body of wate and return th breakwater to a substantially uprigh position,

(237> The joint (3} of each loo ing device allows the ar s and therefore the barrier means and floatable means to rotate in the body of water -under th action of th mov ng body o water. Due to the di ection of the flow the body of moving water collidea with the rear panel ( 2) of the harrier means. The impact of the foody of moving water causes the barrier means to mili, in the ^■ direction of flow and it s» s^¾¾wtiy de orms f om a cuboid d a p rai ieiepiped.

The joint o each mooring; device llows the artss to rotate in a vertic l plana daring use so that they can rise and fall in. accordanc with the dept of the body o ¾at r. It is known and understood that the depth of the, body of water oscillates during tidal and/or wave .motion. Therefore, when the depth of the body o water decreases, the joints (3) of. each mo ring device allow the arms to rotate downwardly in a - ertic l plane unde the action of the foody o water such that the _: barrier iaeans deforms from a cuboid (upright position, expanded condition) to a paraaieiepiped.

{e ^j ip nd'S^ condition), the oro s-seotion l a ea of the barrier means incraases and the internal, pressure decreases. Hence, fluid is drawn into the ar i r m ris via the fluid inlet, s- the barrier eans s driven from a substantially upright, position {ex anded condition) to a tilted position (contracted condition) _r - the cross-section i, area of the barrier; me ns reduces ^' and the Internal pressu e within e barrier me s ¹ increases,.

(257· The energy harnessing device may comprise at least one ump that is countable i the moving body of wares by at least one mooring device according; to a first aspect of the invention. Th.a ulping action of a pump within an ene gy harnessing system is dependent on the reciprocatin tide and/or w e motion acting on the arm (and optional float} and the change, in height of the arm dttlng reciprocating motion,

(266) The pum of an- .energy harnessing system may foe sealed hydraulic system that is configured to pump any suitable hydraulic fluid. The pm& may be configured to draw in wster fro the moving body of water, The pomp may be configured to: pum fluid to a remot location. The pomp may foe coupled to a transduce to convert th pumping action of the pump to other forms of energy. For example,» the pump may b coupled to a hydroelectri transducer t convert to action Of the- . umped fluid info electricit .

(269) Figures 2¾ and 26b depict an example of as ene gy namossing system w: th a deformabis pumping; chamber (C5. The c mb r is generall cuboid in shape and comprises a front wall, rear wall, side - lls, an upper wall and a lower wall, he chamber comprises a fluid inlet (IK) and a fluid outlet COOT) . A hydroelectric transducer (-KG ^' ) is mounted within the chamber adjacent to the fluid, inlet: and fluid outlet. The chamber -is mounted in the body o water by coupirpg a mooring; device to each corner of the chamber. Each corner edge is slidshly mounted dr obupied to the arm of a espective: moorihg device. The arss o the mooring devloe- are sufficientl buoyant so as arrange the chamber- in a generally upright position within the body of water.

(270 The joint (3) of each mooring deyi.ce allows the s iss and, therefore the chamber to rotate in the body of water under t-he action of the moving body of water. Due to the direction of the flo (FLO ,- the body of moving water collides with the ^: rear wail of the chamber. The impact of the bod of moving water causes the arms to rotate and the chamber to deform _* ¾s the depth of the body of water decreases, the a ms to rotate downwardl in a vertical plane so that the c amber deform fro a cu oid (an upright position:, x anded: condition) to a parallelepiped, ^' (. ilted, position, contrasted condition) . As- the depth of tha foody of wa er increases, the buoyant arms rotate upwardly ih a vertical plane so that the chamber is returned to a substantially upright position an it changes f om a paralleiepipeo ¹ . (contracted condition) to a cuboid (expanded condition) , Therefore., under tide and/or wave motion, th¾ _: chamber rsoves in a reciprocating fashion betw en a substantially upright position (expanded condition) as shown in Figure :26a and _: a fell-ted position c n racted condition) a& shown in Figure 26h>

{2:71 As the chamber re urns from a. tilted position: (contracted condition) to ^' & substantially upright position {ex nded condition) , the c oss-sectional area of the: chambe incresees nd the internal pressure decreases. Hence, fluid is drawn into: the chamber vie the fluid: inle . ¾«■ the chamber is driven IrGjT; a .substantially upright position (expanded condition) to a tilted position {contracted condition) , the eross—sectionai area of the chamber reduces and the internal pressure within the chamber increases. Hence, fluid is subse uen l forced to flow out of the chamber via. the fluid outlet, Accordingly, th deformabXe chamber acts as a hydraulic, pump that is driven b the reciprocating motion of the body of water, In this particular: mbodimen th pumping actio of the hlto and outflow of fluid is utilised to driv the doubl action hydroelectric transducer.
