Description
An Offshore PiLe and a Pile Sleeve Interfacing System
Field of the Invention
The invention reLates to an offshore piLe and piLe sLeeve interfacing system, preferabLy the offshore piLe being a resource extracting conductor and the piLe sLeeve being a centre sLot support sLeeve.
Background to the Invention
A known offshore piLe and piLe sLeeve interfacing system comprises a centre sLot support pLate which interfaces with a resource extracting conductor pLate.
The centre sLot support pLate comprises three evenLy spaced shouLders which are curved and protrude from its inner surface; between each neighbouring shouLder protrusion is a gap, which cooperates a Locating Lug/protrusion from a conductor pLate. When the tugs of the conductor pLate are aLigned with the gaps of the centre sLot support plate, they pass through the centre sLot support pLate. The conductor pLate is then subsequentLy rotated reLative to the centre sLot support pLate, whereby each Lug of the conductor pLate Locate within a recess Located within a Load bearing surface of a shouLder protrusion of the centre sLot support pLate. Both the Locating Lug/protrusion and the cooperating recess of the Load bearing surface are shaped in the form of an isosceLes trapezium.
Furthermore, the centre sLot pile sLeeve attached to the centre sLot support pLate further comprises a retaining bolt, which cooperates with a Lower surface of an upper centraLising ring Located on the outer surface of the resource extracting conductor. The retaining boLt prevents the centre sLot piLe sLeeve from moving aLong a verticaL axis on the resource extracting conductor. The centre slot piLe sLeeve aLso incorporates a second cLamping boLt that cooperates with the upper surface of the upper centraLising ring to prevent the resource extracting conductor from rotating reLative to the centre sLot piLe sLeeve.
The disadvantages of the known offshore piLe and piLe sLeeve interface system are: The cooperating isoscetes trapezium shapes of both the conductor pLate protrusions1 and the recesses Located within the supporting shouLders of the centre sLot suppoit plate. The bottom and side suifaces of each recess, of the centre sLot support pLate, communicate a compressive force to the top and side surfaces of each protrusion of the conductor. Therefore, the side waLLs of both the protrusions and cooperating recesses Limit the communication of a compressive force from the bottom surface of each recess to the top surface of each protrusion.
The cooperating isoscetes trapezium shapes of the conductor pLate protrusions and a cooperating gap of the centre sLot support pLate provide a Loose fit whereby gaps exist down each side waLL, thereby any subsequent rotation of the conductor pLate reLative to the centre support pLate, wiLL cause the conductor pLate to ride up and down the side waLLs of the trapezium recesses of the centre sLot pLate; and * The centre sLot piLe sLeeve comprises compLicated and unmaintainabte bolt configurations that cLamps and retains the centre sLot piLe sLeeve onto the resource extracting conductor.
Figure la shows an end view of a known centre sLot support pLate 1, which incorporates three supporting shouLders 2 that protrude inwardLy. In use, the known centre sLot support pLate 1 is attached to an end of a centre sLot piLe sLeeve (not shown).
Figure lb shows an end view of a known conductor pLate 3, which incorporates three protrusions 4 that protrude outwardLy. In use, the known conductor pLate 3 is attached to an end of an offshore piLe (not shown), such as a resource extracting conductor piLe.
Figure lc shows an end view of a known conductor pLate 3 cooperating with the centre sLot support pLate 1 whereby the protrusions 4 of the conductor pLate 3 are aligned with the gaps of the centre sLot support pLate 1.
Figure ld shows a known centre sLot support pLate 1 instaLLed on a known conductor pLate 3, whereby the protrusions 4 of the known conductor pLate 3 have passed through the gaps of the centre sLot support pLate 1 and are rotated to their Load bearing positions on the shouLders 2 of the centre sLot support pLate 1.

DetaiLed Description of the Figures
Figure 2a shows an end view of a centre sLot support ring 20, which incorporates three Load bearing shouLders 21 protruding from the inner surface of the ring 20 and are evenly spaced from each other by 120°. Between each shoulder 21 is a gap 22 which allows a passing of an aLigned protrusion 31 (see Figure 2b) from a conductor support plate.
Figure 2b shows an end view of a conductor supporting pLate 30 which has three protrusions 31 which are evenly spaced from each other by 120°. Each protrusion 31 is sized so that it can pass through the gaps 22 within the centre slot ring (see Figure 2a).
Figure 2c shows a conductor support pLate 30 aLigned and assembled with a centre slot support ring 20 whereby the protrusions 31 of the conductor support pLate 30 are aligned with the gaps 22 within the centre sLot support ring 20.
Figure 2d shows an instalLed orientation of the conductor, where the conductor and the conductor support plate 30 have been rotated relative to the centre sLot support ring 20 by 60°.
Figure 2e shows a part cross sectional view of a resource extracting conductor 60 instaLled within a centre slot pile sleeve 61. The top and bottom portions of the pile sLeeve 61 comprise a 360° conical guide 62. The resource extracting conductor 60 comprises an upper centralising ring 63 which is aligned and abuts with one or more supporting eLements 65 that protrude from the inner surface of the centre slot pile sleeve 61. The resource extracting conductor 60 further comprises a conductor support plate 66, which comprises a Lower centratising ring 64 which is aligned and abuts with one or more supporting elements 67 that protrude from the inner surface of the centre slot piLe sleeve 61. A centre slot support ring 68 is attached the bottom end of the centre slot pile sLeeve 61.
Figure 2f shows the installed orientation of the centre slot support ring 68 and a cooperating conductor support plate 66. The centre sLot support ring 68 comprises a rectangular recess 70, which is located in the bottom surface of the support ring 68 and has a Load bearing surface 71 that cooperates with the rectangular protrusion 72 of the conductor support plate 66. The Lower centraLising ring 64 of the conductor support plate 66 cooperates with one or more supporting elements 67 that protrude from the inner surface of the centre slot pile steeve 61. The rectangular protrusion 72 comprises a load bearing top surface 73, which locates within the rectangular recess 70 of a centre slot support ring 68 and cooperates with the load bearing bottom surface of the rectangular recess 70.
In use, a pile sleeve is placed over an off shore pile, such as a resource extracting conductor, whereby the pile sLeeve is moved along the Length of the offshore pile to its intended location. The piLe sleeve comprises a centre slot support ring at its bottom end, which interfaces with a conductor support plate located on the offshore pile. When the pile sleeve is located at the intended position on offshore conductor, offshore conductor is rotated relative to the pile sleeve; therefore enabLing the rectangular protrusions of the conductor support plate to locate and engage with the rectanguLar recesses located within supporting shouLders centre slot support ring.
The rectanguLar recesses of the centre sLot support ring provide a snug fit the rectanguLar protrusions of the conductor support pLate, whereby the top Load bearing surface of the rectanguLar extend across the width of the rectangular recess and thereby engages with the whoLe bottom Load bearing surface rectanguLar. This interface of the Largest Load bearing surfaces of each rectanguLar protrusion and cooperating rectanguLar recess, significantLy increases the amount of compressive force that can be communicated from the centre sLot support ring to the conductor support pLate. No compressive force is communicated from the centre sLot ring to the conductor support vis the side waLLs of each rectanguLar protrusion and cooperating rectanguLar recess, therefore not Limiting the size and capacity of the Load bearing surfaces of each rectanguLar protrusion and cooperating rectanguLar recess.
The snug fit of each rectanguLar protrusion of the conductor support pLate, within a cooperating rectanguLar recess of a centre sLot support ring, enabLes the side waLLs of the protrusion to abut the side waLLs of the recess and therefore prevents the rotationaL movement of the centre sLot support ring in reLation to the engaged conductor support pLate. The verticaL side waLLs aLso prevents the centre sLot support ring from Lifting and becoming separated from the engaged conductor support pLate due to any rotationaL forces that may be appLied to the centre sLot support ring and / or conductor support pLate.
The piLe sLeeve is intended to support and brace one or more resource extracting conductor supported structure such as an oiL weLL or any other offshore structure.
Further, the piLe sLeeve may be used to support and brace one more offshore piLes for a wind turbine supporting structure.
