In another aspect, the present invention resides in a method for mooring a ship comprising the steps of fixing a mooring member to the floor of a body of water, said mooring member having a configured - pa -inner surface including a groove which extends around the inner periphery thereof; inserting a coupling cone having a configured outer surface corresponding to the configured inner surface of said mooring member, into said mooring members, said coupling cone containing a slot which extends along the periphery thereof; detachably locking said coupling cone to said mooring means by inserting a locking means into said slot and said groove; and securing said coupling cone to a coupling arm pivot ably unwed to a ship.
Brief Description of the Drawings FIG. 1 is a perspective view schematically illustrating the apparatus of the present invention.
FIG. 2 is a cross-sectional view which closely illustrates the major portion.
Description of the Preferred Embodiments Referring to FIG. 1, a ship S is illustrated having a coupling arm 1 coupled to a coupling cone 2 of a mooring member 3 which may be a mooring pole or a mooring buoy anchored to the bottom of the sea; coupling cone 2 is illustrated as having rubber packing 7 at its base resting on mooring member 3.
Referring to FIG. 2, the lower portion of the coupling cone
2 has an inverse conical shape to engage with the flaring recess formed in the top portion of mooring member 3. When coupling cone 2 engages mooring member 3, locking pin 5 is actuated by hydraulic pressure generator 4 in coupling cone 2 and is inserted into groove 6 ~onmed in the inner wall of a flaring recess in the upper portion of mooring number 3. onus, coupling cone 2 is locked to mooring member 3.
I, I, . . .
~;22~
, US -3-The upper surface of locking pin and the corresponding upper surface ox groove 6 are tapered to engage with each other in the Norm of a edgy As pin 5 is inserted, coupling cone 2 is downwardly pulled relative to the mooring member 3, whereby a rubber packing 7, provided under a jaw portion in the middle ox coupling cone Z, is compressed by a predeter~uned amount between coupling cone 2 and the upper edge ox mooring member 7. Therefore, after coupling, water is prevented rum entering moo coupling cone 2.
Rubber packing 7 also works to reduce the shock produced during the engagement of coupling cute 2.
A predetermined number I locking pins 5 will be provided in the circumference of coupling cone 2. Groove 6 will be continuously formed around the puff y ox mooring member 3. Therefore, coupling cone 2 may be enraged in any direction about the perpendicular axis ox -mooring member I.
Coupling arm 1 is pivotal attached to the upper portion of coupling cone 2 via universal joint-8. Universal joint 8 may be a spherical bearing.
In order to transport crude oil and other fluids prom the seabed to the ship or prom the snip to the seabed, the apparatus a the present invention may include a pipeline which is briefly de æ robed below. Namely, a rigid pipe 9 or transporting fluid along coupling arm 1 is connected to the tow path in rotary ring 1' at the top ox coupling cone 2 through n exile pipe 10. Flexible pipe 10 may be a moldable pipe with swivel joints.
A rigid pipe 12 which connects with the slow path in rotary ring 11 is hung in coupling cone 2, and a moldable pipe 13 with swivel joints is connected to the lower portion thereon. Foldable pipe 13 is connected by Lange 15 Jo rigid pipe 14 which rises trim mooring member 3.
When coupling cone 2 and mooring member 3 are to be engaged or disengaged, the pipeline can be attached or detached at Lange lo.
The moldable pipe 13 with swivel joints may be replaced by a flexible pipe.
Although the diagram illustrates only one pipeline system, it is easy to install a plurality no pipeline systems in the same manner 3i~25i2~36 ~76 -4-Furthermore, an entrance/exit port 16 with a water-tight door (or water-tight cover), a handrail 17 and a ladder 18 may be provided Jo workers can enter coupling cone 2 to start or stop hydraulic pressure generator 4, to attach or detach Lange 15, or to check the coupling system.
The functioning of the apparatus when ship S is moored to mooring member 3 by coupling arm l-via coupling cone 2 Jill now be explained. Ship S drifts, tilts, pitches and rolls with the ocean current, tide, wind and waves, and the forces are transmitted to o coupling cone 2 via coupling arm 1. Coupling arm 1 and coupling cone 2 are able to rotate due to universal joint 8. rnerefore, no bending movement or twisting movement is produced in this portion; only the axial force is transmitted to achieve the purpose of mooring.
When mooring member 3 is a buoy, anchored by anchoring chains l; only and is singable, universal joint 8 may be replaced by a joint which rotates about the vertical axis only.
Fluid may be transported from the seabed to ship S through rigid pipe 14, Lange 15, foldable pipe 13 with swivel joints, rigid pipe 12, flow path in the rotary ring 11, flexible pipe 10 and rigid pipe 9;
Even when relative displacement has taken place between coupling arm 1 and coupling cone 2 due to the motion of ship S or mooring member 3, flexible pipe 10 and rotary ring 11 move following the displacement, and transportation of the fluid is not disturbed.
Coupling cone 2 can be separated from mooring member 3 in the hollowing manner. First, the operator enters into coupling cone 2 through entrance exit port 16. The operator may transfer directly from the work boat (not shown, or may transfer prom ship S which is moored via coupling arm 1. The operator enters coupling cone 2 and disengages flange 15. A stop valve (not shown) may be provided at the top proton ox rigid pipe 14 and at the lower portion of foldable pipe 13 with swivel joints. By closing the stop valves, the fluid in the pipes is prevented prom gushing out.
The operator starts the hydraulic pressure generator 4 so I that the locking pins 5 are withdrawn by the hydraulic pressure to a position indicated by the dot-dash line.
I
The hydraulic pressure generator 4 will have a hydraulic pump that is actuated by, for example, compressed air. The compressed air will be supplied from the moored ship via the rotary ring 11 through a pipeline system with a construction similar to that ox the pylon system described above or transferring the fluid, en from a ~orkboat through the entrance port 16. Thus, the preparation for separation is completed. When the coupling arm 1 is lifted, the :oupllng cone 2 is separated from the mooring pole I. The coupling arm 1 e n be lifted by a listing device (not shown) such as a crane installed at the bow of a moored ship.
The coupling cone 2 and the mooring member 3 are contacted and fastened chiefly via the rubber packing 7. A s~r~icient gap is maintained between the inverse conical portion at the lower portion of the coupling cone 2 and the Planing recess at the upper portion of the mooring member to insure against the possibility ox the two members sticking together.
To couple the two members, the operations described above should be performed in reverse. In this case, since the top portion ox mooring member 3 is glared, accurate centering to not necessary for tube insertion ox coupling cone 2. Thus the coupling operation may be be carried out more easily. Effects and advantages of the s~biect apparatus for mooring ships may be summarized as follows.
Movable locking members such as locking pins 5 and other equipment are installed in the coupling cone making it possible to maintain and check the apparatus when the skip is docked, eliminating the need ox performing maintenance operations in the middle of a dangerous ocean. Thus, the apparatus owe present invention contributes to the enhancement ox safety.
The mooring member requires no maintenance (or preventing the infiltration ox water and the like) aster disconnecting from coupling cone 2 and being left on the ocean because no apparatus or moving part necessary for coupling is installed on mooring member 3.
Since thy coupling mechanism is very simply constructed, the disconnection or the coupling can be effected within short periods of I time.
Sue 1~76 The ship can be quickly disconnected in an emergency case.
Therefore, the conditions for disconnection can be set to suitable values with reference to the operation rate, such that the conditions of external forces for the mooring apparatus can be reduced to practical ranges.
