Definitions

  • the present invention relates to access apparatus for enabling transfer of personnel between an offshore vessel and an installation moving relative to the vessel, such as an offshore wind turbine.
  • the invention also relates to a locating apparatus for use with such access apparatus and to a location and access assembly incorporating such apparatus.
  • Another access apparatus which has a passive mode in which an end of a gangway remote from the vessel is located in a desired position adjacent the installation to which access is to be provided, and a passive mode for use when the end of the gangway has been attached to the installation.
  • this arrangement suffers from the drawback that it is difficult to securely attach the end of the gangway to the installation.
  • Preferred embodiments of the present invention seek to overcome one or more of the above disadvantages of the prior art.
  • an access apparatus for enabling transfer of personnel between an offshore vessel and an installation moving relative to the vessel, the apparatus comprising:-
  • tensioning means for urging the engaging means towards the first end to place the tensile member under tension when engaged by the engaging means, this provides the advantage that only tensile loads are transferred to the platform, which reduces bending moments on the access apparatus and makes the apparatus easier to install.
  • the apparatus can also be constructed such that it is light but strong and flexible, enabling the engaging means to engage the tensile member without high impact loads.
  • the apparatus may further comprise guide means for engaging at least one said tensile member to generate a component of tensile force in said tensile member transverse to a line joining said engaging means and said first end.
  • This provides the advantage of assisting in restraining movement of the access means relative to the installation.
  • the engaging means may be adapted to extend through at least one aperture in said guide means and retract at least one said tensile member through said aperture to cause said guide means to engage said tensile member.
  • the access means may comprise a plurality of access portions, wherein said first end is provided on a first access portion, said second end is provided on a second access portion, and said second access portion is moveable relative to said first access portion.
  • the engaging means may comprise releasable latching means.
  • the latching means may be adapted to release the or each said tensile member engaged thereby when tension in said tensile member exceeds a predetermined level.
  • the engaging means may further comprise release means moveable relative to said latching means between a latching condition and a release condition, wherein the release means is adapted to engage the second access portion and move relative to the latching means from the latching condition to the release condition when tension in a said tensile member engaged by said latching means exceeds a predetermined level.
  • the apparatus may further comprise first biasing means for biasing said release means towards said latching condition.
  • the tensioning means may comprise second biasing means for urging the engaging means towards the first end.
  • the tensioning means may comprise third biasing means for urging the second end towards the first end.
  • the engaging means may comprise at least one hook.
  • the apparatus may further comprise positioning means operable from said vessel for adjusting the position of said engaging means relative to said vessel.
  • the positioning means may be adapted to adjust the position of said second end relative to said first end.
  • the positioning means may be adapted to cause pivoting of the access means about a first axis relative to the support means.
  • the positioning means may be adapted to cause pivoting of the access means about a second axis relative to the vessel.
  • the apparatus may further comprise notification means for generating a notification signal of said vessel tending to move out of range of said installation.
  • This provides the advantage of enabling an operator to correct the position of the vessel to maintain operability of the access apparatus.
  • a locating apparatus adapted to be engaged by engaging means of an access apparatus as defined above, the locating apparatus comprising:-
  • loop forming means for forming a loop from at least one said tensile member, this provides the advantage of assisting engagement of the tensile member with the engaging means.
  • the loop forming means may comprise fourth biasing means for biasing ends of at least one said tensile member along divergent directions relative to said installation.
  • the apparatus may further comprise at least one engaging portion mounted to at least one said tensile member and adapted to be engaged by said engaging means and to preventing the minimum bend radius of said tensile member becoming lower than a predetermined value.
  • the apparatus may further comprise at least one support for supporting at least one said tensile member, wherein the support is pivotably mounted to the installation in use.
  • a location and access assembly comprising an access apparatus as defined above and a location apparatus as defined above.
  • a location and access assembly embodying the present invention includes an access apparatus 2 of a first embodiment of the present invention and a locating apparatus 34 for enabling transfer of personnel between an offshore vessel 4 and an installation such as an offshore wind turbine 6.
  • the access apparatus 2 has access means comprising a gangway 8 having a first gangway section 10 pivotably mounted about a generally horizontal pivot axis 12 to a platform 14 and a second gangway section 16 slidably mounted to the first gangway section 10 such that the distance between a first end 18 and a second end 20 of the gangway 8 is adjustable.
  • the platform 14 is supported on a plinth 22 on the deck 24 of the offshore vessel 4 and is rotatably mounted to the plinth 22 via a slew ring 26 to enable rotation about a generally vertical axis.
  • the gangway 8 is pivotable about horizontal axis 12 by means of a lift cylinder 28.
  • the first 10 and second 16 gangway sections are mounted to each other such that personnel can walk along the gangway 8 at any relative position of the first 10 and second 16 gangway sections.
  • a spring 29 mounted between the first 10 and second 16 gangway section urges the second end 20 towards the first end 18.
  • Engaging means in the form of a hook 30 extends from the second end 20 of the second gangway section 16 and is slidably mounted to the second gangway section 16.
  • the hook 30 passes through a bridle constraint 32 fixed to the second gangway section 16.
  • the bridle restraint 32 has an aperture 33 ( Figure 2 ) having a widened central portion 35 that allows the hook 30 to pass through and tapers to narrowed side portions 37.
  • the second gangway section 16 and hook 30 are interconnected such that the position of the hook 30 can be extended hydraulically and retracted with sufficient force to place a tensile member in the form of a wire 36 of the locating apparatus 34 under tension.
  • the bridle restraint 32 is provided with guides 40 ( Figure 5 ) arranged on opposite sides of the aperture 33 for engaging the wire 36, the purpose of which is explained in greater detail below.
  • the tensile member in the form of a wire 36 of the locating apparatus 34 is pivotably mounted at its ends 39 to supports 38 which are mounted to the offshore installation 6.
  • the ends 39 of the wire 36 are pivotable relative to the supports 38 and are biased by means of springs 43 towards the condition shown in Figure 3 , in which the wire 36 forms a loop and thereby provides a larger target for the hook 30.
  • the side of the wire 36 remote from the installation 6 is lower than its ends 39 ( Figure 1 ), which assists in locating the hook 30 on the wire 36.
  • the ends of the wire 36 are connected by an engaging member 42 which is engaged by the hook 30 to prevent the bend radius of the wire 36 becoming less than a predetermined minimum value.
  • an operator on the vessel 4 controls the angle, slew position and hook extension position to locate the hook 30 in a desired position relative to the vessel 4.
  • the hook 30 is extended from the aperture 33 of the bridle restraint 32 by means of actuator 41, and the operator operates controls to limit movement of the hook 30 relative to the locating apparatus 34 as the vessel 4 approaches the installation 6.
  • the hook 30 engages the engaging member 42 on the wire 36 and the hook 30 is then retracted into the aperture 33 of the bridle restraint 32 to place the wire 36 under tension as shown in Figures 4 and 5 .
  • the gangway 8 is placed under tension and the second gangway section 16 extends relative to the first gangway section 10.
  • the lift cylinder 28 and slew cylinder (not shown) are then switched to a floating condition in which they can move freely to allow free movement of the gangway sections 10, 16 relative to the plinth 26.
  • the position of the hook 30 becomes loosely restrained by the wire 36 of the bridle, and as the hook 30 retracts, the gangway 8 extends and the hook 30 passes through the aperture 33 of the bridle restraint 32 which progressively constrains the position of the second end 20 of the gangway.
  • the tension in the wire 36 of the bridle increases until the second end 20 of the gangway 8 is fully supported by the tensioned wire 36.
  • the ends of the wire 36 are then located in the side portions 37 of the aperture 33 in the bridle restraint 32 and engage the guides 40 as shown in Figure 5 .
  • This causes the ends 39 of the wire 36 to pivot inwards relative to the supports 38 so that the tension in the ends of the wire 36 has a component transverse to the direction in which tension is applied by the hook 30.
  • the gangway 8 is then free to extend and contract and the bridle acts as a gimbal, providing 6 degrees of freedom between the vessel 4 and the installation 6.
  • Notification means (not shown) provides a signal to warn if the vessel 4 is moving out of range of the offshore installation 6, or if wave motions are too great. This can then be used by a dynamic positioning system of the vessel 4 to correct the position of the vessel 4.
  • the wire 136 is engaged by a releasable latch 150 which has a first latching member 152 and a second latching member 154 arranged such that the latch 150 only engages the wire 136 if it approaches the latch 150 in the direction of arrow D. This reduces the risk of accidental latching by the latch 150.
  • the latch 150 is mounted to a support member 156 which is slidable by means of actuator 141 relative to the second gangway section 116 and extends through the bridle restraint 132.
  • Release means in the form of an inner rod 158 is slidably mounted to the support member 156 and is urged by a gas strut 160 into engagement with an end wall 162 of the support member 156 to urge the latch 150 to its latching condition.
  • the latch 150 and support member 156 are urged outwards of the second gangway section 116 until a flange 164 on the inner rod 158 engages a stop 166 on the second gangway section 116, preventing further outward movement of the inner rod 158 relative to the second gangway section 116.
  • the inner rod 158 is urged against the action of gas strut 160 out of engagement with end wall 162 of support member 156 to move the first 152 and second 154 latching members relative to each other to bring the latch 150 into its release condition to release the wire 136.
