Definitions

  • This invention relates to systems for transferring peo- pie between two spaced platforms subject to relative move ⁇ ment during the transfer process, and more particularly to an articulated ramp providing a temporary bridge connecting the platforms.
  • the platforms may be free floating on the water surface above the drill site or well ⁇ head, or tied to the ocean floor by tether line, or elevated above the water surface on stilts reaching down to the ocean floor below.
  • the platforms are subject to more or less constant motion due to the forces of wind and waves acting on the structure, complicating such tasks as the loading and unloading of supplies and workmen.
  • the present invention employs two ramps, a main ramp and an outer ramp.
  • the main ramp in its preferred form is swingably maintained on a rotatable pedestal secured to the deck of the ship.
  • the outer ramp is connected to the main ramp through an intermediate or mid-ramp platform which is stabilized with respect to the deck of the ship or platform on which the main ramp is mounted through the use of a par ⁇ allelogram linkage which includes the main ramp and main ramp handrails.
  • the outer ramp is movable about two right axes to accommodate movement of the ramp assembly between a stowed position and a bridge forming position connecting the ship or other platform on which the main ramp is mounted and a relatively movable platform such as an offshore oil plat- form.
  • a principal object of the present invention is to pro ⁇ vide an articulated ramp which is capable of making and maintaining a bridge between two spaced platforms at least one of which is subject to substantially continuous movement relative to the other within a wide envelope of such move ⁇ ment in any direction due to waves and wind or other forces.
  • Another object of this invention is to provide a ramp which has substantial reach and which is useable on ships in high sea state conditions.
  • Still another object of this invention is to provide a ramp which is capable of adjusting to platforms of different and varying heights, including the capability of reaching to a platform of much greater height than the ship on which it is mounted.

  • Pedestal 17 is provided with a base plate 18 which forms the lower landing for spiral stairway 19.
  • Spiral stairway 19 wraps around pedestal 17 to an upper landing 21 at the top of the pedestal.
  • a pair erf; redundant slewing drive motors 15 and 15' are car ⁇ ried on base plate 18 as shown in FIG 4. These drive motors engage a ring gear 20 on kingpost 14.
  • a pair of posts 22 and 23 extend upwardly from the base of pedestal 17 beyond the upper landing to hingedly support ramp assembly 11 through pins as at 24 for movement about an axis normal to the axis of pedestal rotation (FIG 5) .
  • Ramp assembly 11 comprises a main ramp 26, an intermediate or mid-ramp platform 27 and an outer ramp 28.
  • Main ramp 26 is hingedly connected to a pair of verti ⁇ cally extending arms 29 and 31 on mid-ramp platform 27 through pins as at 30.

  • Handrails 32 and 33 on main ramp 26 may be suitably braced as shown in FIGS 2 and 5 by support stanchions 47.
  • the stanchions should be swingably connected to the main ramp and to the handrails so as to provide added support for the handrails, but not resist the limited angular changes they must undergo as the main ramp is swung in elevation.
  • line 55 acting between arms 22 and 29 or 23 and 31 through pins 57 and 58 serves as a tension member in the preferred embodiment to eliminate compression in handrail 32.

  • the steps are formed as the main ramp is moved up in elevation.
  • Mid-ramp platform 27 includes an out ⁇ er ramp support drum 61 supported on the platform under its deck 64 for rotation about shaft 60 on an axis generally parallel with the axis of rotation of pedestal 17. Posi ⁇ tioning of drum 61 about its axis of rotation is controlled by motor 62 through gearing 63.
  • Outer ramp 28 is cantilevered intermediate its ends from drum 61 on shaft 65 and is movable on the shaft about an axis normal to the drum axis of rotation as shown in FIG 3, whereby the outer ramp may be swung on shaft 65 between a stowed position (not shown) along side main ramp 26 to an extended position for connection with an oil platform as illustrated in FIG 1. Still referring to FIG 3, a hydraulic actuator 66 acting between mid-ramp platform 27 and outer ramp 28 may be pro ⁇ vided to selectively control the movement of the outer ramp about shaft 65, to clamp its movement, or permit it to rotate freely as directed by commands inputted by the ramp operator at control station 46.
  • a counter weight 68 may be added as best shown in FIGS 2 and 3.
  • Outer ramp 28 connects the articulated ramp assembly to oil platform 12 through a ball joint 69 carried on tubular guide or shaft 70 which projects from outer ramp 28 below the walkway as best shown in FIG 10.
  • shaft 70 is slidably sup- ported in bearings 102 and 103 permitting limited axial movement of the shaft and ball joint.
  • Compression spring and shock absorber packs 97 and 98 acting between flange 99 on outer ramp 28 and arms 104 and 106 extending from shaft 70, normally urge the ball joint 69 and shaft 70 towards an extended position projecting forwardly of the outer ramp.
  • Tension springs 109 and 110 each connect at one end to arms 104 and 106, respectively, and at their opposite end to levers 112 and 113 formed on gate 93.
  • Bearing tubes such as 114, one on either side of gate 93, support the gate for swinging movement between open and closed positions on outer ramp 28 while coil spring 116, one for each bearing tube 114, normally urge the gate closed.
  • ramp station 13 on oil platform 12 includes a deck threshold 73 adapted to overlap the end 71 of outer ramp 28 and provide solid footing for those being transferred between the ship and oil platform when the ramp is secured to the platform.
  • Below threshold 73 is a rigid box-like structure 74 having a slit 76 formed therein which extends through the threshold and communicates with a centrally located opening through the box-like struc- ture forming a socket 77 on one side of the box-like struc ⁇ ture.
  • Socket 77 is adapted to mate with ball joint 69 on outer ramp 28.
  • the opening therethrough forms a seat 78 for an anchor line stop fitting 79.
  • Ball joint 69 on outer ramp 28 is drawn into mating engagement with socket 77 for securing the outer ramp to oil platform 12 by anchor lines 81 and 82 carried on articulated ramp assembly 11.
  • anchor lines 81 and 82 are each tied to separate constant tension winches 83 and 84 mounted on pedestal plate 18 and suitably reeved along the underside of ramp assembly 11 such as by guide pulley 86 on outer ramp 28 as shown in FIG 3.
  • the free end of anchor lines 81 and 82 extend through opening 87 formed in ball joint 69 to connect with anchor line stop fitting 79.
  • articulated ramp assembly 11 is cinched to oil platform 12 providing a secure bridge between ship 10 and the oil platform.
  • the anchor line is a key element in system safety, and therefore two separate anchor lines 81 and 82 and winches 83 and 84 are preferably employed to increase system reliabil ⁇ ity through redundancy. It should also be noted that the anchor lines, in passing through the ball and socket are subject to being pinched under extreme angular movement. To prevent shearing of the anchor lines under such conditions, the opening through ball 69 and socket 77 should be free of sharp cutting edges. These parts are preferably either coated with a resilient liner or fabricated using a material which is somewhat compliant, yet of sufficient strength to carry the loads to which it will be subjected.
  • articulated ramp assembly 11 is unfastened from its stowed position and prepared for deployment.
  • a messenger line 91 is passed between the oil platform and the ship by rig man 96.
  • the ramp operator identified in FIG 1 by reference numeral 90 catches the mes ⁇ senger line and connects it to anchor line pendant 92, which is that short portion of anchor lines 81 ' and 82 which extend beyond anchor line stop fitting 79. He then assumes his station at ramp control console 46 atop pedestal 17 and pro ⁇ ceeds to elevate main ramp 26 to the height of oil platform 12. He simultaneously rotates outer ramp 27 so that it points towards the oil platform.
  • anchor lines 81 and 82 are fixed on the oil platform by dropping the anchor lines through slot 76 on the oil platform to position anchor line stop fitting 79 against seat 78 on box structure 74.
  • the ramp operator then activates the constant tension winches 83 and 84 to bring anchor lines 81 and 82 under load.
  • the brake on slewing drive motor 62 for outer ramp 28 is released, and increasing tension on the anchor lines pulls the ramp into transfer position drawing ball 69 firmly into engagement with socket 77, causing the springs in spring and shock absorber packs 97 and 98 to compress as shaft 70 and ball joint 69 retract to where outer ramp end
  • Ramp gate 93 which forms a part of the handrail restraint system 94 on outer ramp 28, is automatically opened by the actuating mechanism shown in FIG. 10 through retraction of ball joint 69 after the ball is placed in platform socket 77. Gate 93 will automatically close if the ball should pull away from the socket due to relative move ⁇ ment between ship 10 and platform 12 which exceeds the capa- bility of the ramp, so that personnel will not step or fall off the end of the ramp if it is not in proper transfer position.
  • the ramp oper ⁇ ator and the rig man make sure the ramp is clear. Thereaft ⁇ er the ramp operator effects closure of gate 93 by releasing tension on the anchor lines as the rig man disconnects the anchor lines and stop fitting 79 from box structure 74 on the oil platform. The ramp operator then rotates the ramp assembly away from the oil platform, slewing outer ramp 28 alongside main ramp 26, and stows the ramp as the ship pro ⁇ ceeds to its next transfer point.
  • winches 83 and 84 are disclosed when only one may suffice where the added safety of redundancy is not required.
  • winches 83 and 84, shown mounted on pedestal base plate 18, may conveniently be located else- where on ramp assembly 11 such as to serve partially or wholly as the counterweight 68 on outer ramp 28, thus serv ⁇ ing a dual purpose within the scope of these teachings.
