Is stored in a pipe storage near the drilling tower classified by type and diameter, and these pipes are loaded one by one from the pipe storage to the drilling tower based on the excavation schedule. On the contrary, it is necessary to carry it out.

For example, in a semi-sub type rig which is an offshore oil rig shown in FIG. 20, a drilling tower 101 is provided at the center of a deck structure 100, and a pipe storage 102 is provided near the drilling tower 101. The pipe storage 102 is provided with a drill pipe storage 103, riser storages 104 and 105, and casing storages 106 and 107, a pipe handler 108 and a bridge crane 109, and conveys the pipe 111 from the pipe storage 102 to the drill floor 110. A pipe handler 112 is provided for storing the drill pipes in the drill pipe storage 103, and the casing pipes in the casing storages 106 and 107 in a plurality of rows and a plurality of stages in a bale-like manner. However, riser pipe (nominal diameter 21 inches x
50 feet, maximum outer diameter 45 inches), flanges are attached to both ends of the main pipe, and 3 to 4 small-diameter accessory pipes (control pipe, etc.) are attached to the outer peripheral side of the main pipe via both flanges. a four buoyant body mounting a structure located between the accessory tube to the outer peripheral side (Note, also that there is no buoyancy), in order to prevent damage to the accessory pipe and the buoyant body, riser storage 104, In 105, the pipes are vertically aligned through a pipe stanchion and stored in a stacked state through a plate-shaped end support member, or a pipe stanchion is omitted and a U-shaped pipe end can be received. They are stored in a stacked state through an end support block having a recess.

Here, since the drill pipe has few outer diameters, it is often stored in a pipe storage device 120 dedicated to the drill pipe as shown in FIG.
The pipe storage device 120 includes a racking frame support pillar 121 and a plurality of racking frames 122.
Is rotatably pivoted in multiple stages and at one end, and a hydraulic cylinder 123 for rotating each racking frame 122 up and down is provided. An elevator pillar 124 is provided at the free end of the plurality of racking frames 122. A pipe elevating machine 126 for elevating the pipes 125 one by one is provided.

An automatic pipe sorting and extracting device is described.

[0006]

As shown in FIG. 20,
The pipe storage method, in which a large number of pipes are stored in a pile in the pipe storage, tends to cause load collapse under conditions of swaying on the ocean, and requires heavy work such as slinging work in which the crane wire is hung around the pipe when loading and unloading the pipe. To accompany,
There is a problem that automation of pipe loading and unloading is difficult, and in particular, in the case of a riser pipe, heavy-duty labor is required to remove and attach the end supporting member and the end supporting block each time the pipe is loaded and unloaded. In the pipe storage device shown in FIG. 21 , the pipe can be carried in and out by rolling it, but the riser pipe does not have a circular cross section, so it cannot be carried in and out by rolling. is there. The device disclosed in the above publication is a device for automatically selecting pipes, and is essentially not suitable for storing a large number of pipes.

After that, the rear lift table 52 is raised to the raised position, and then the stopper member 76 of the rear stopper mechanism 75 is switched to the stop position. Thereafter, by repeating the above-mentioned procedure in the same manner, the riser pipes P are sequentially installed from the pipe storage devices 2 to 1
You can carry out books one by one.

When the riser pipe P is carried into the pipe storage device 2, the reverse procedure to the above may be performed.
When loading and unloading a specific type of riser pipe P, the above procedure may be repeated as many times as necessary. As described above, according to the pipe storage device 2, by providing the transfer carriage 30, the riser pipe P having a circular cross section and an irregular cross section can be reliably supported through the U-shaped receiving stand 31 of the transfer carriage 30, and the riser can be securely supported. Since the pipe P is constrained to move through the pedestal 31, the load does not collapse. In addition, since the transfer carriage 30 is guided through the guide frame 11 and the support rollers 37, the storage state is stable, and the transfer carriage 30 can be circulated and moved in the upper and lower stages, so that the riser pipe can be moved with respect to the desired transfer carriage 30. The P can be carried in and out, and the heavy labor associated with storing the riser pipe P can be eliminated, and the storage and transfer can be automated and labor-saving. In addition, the carriage transfer devices 40D and 40U are
The transfer hook member 45, the transfer hydraulic cylinder 46, the engagement / disengagement hydraulic cylinder 47, and the like are very simply configured, and the transfer carriage 30 can be transferred with a strong transfer driving force. Further, the carriage lock device 15 can reliably prevent the transfer carriage 30 in the stored state from moving. In addition, the lifting device 50 includes a guide column 51, a lifting hydraulic cylinder 71,
It has a simple structure consisting of the lifting table 52, and also the lifting table 5
Since the carriage movement restraint device 60 is provided on the second carriage 2, it is possible to reliably restrain the movement of the transfer carriage 30 transferred to the lift table 52. By switching the operating hydraulic pressure, the transfer drive mechanism 41 on the upper front side and the lower rear side is used as the transfer brake mechanism 41B, and the transfer brake mechanism 41B on the upper rear side and the lower front side is used as the transfer drive mechanism 41. It is also possible to transfer the riser pipe P in the opposite direction (counterclockwise direction in FIG. 3). Note that the pipe storage device 2A of the modified example of FIG. 19 may be configured in three stages, or may be configured in a plurality of stages of three or more.
