Description

Test mandrel and working equipment mounting device {Racker for Test Mandrel and Working Equipment}

The present invention relates to a test mandrel and a device for holding work equipment, and more particularly, to stably mount a test mandrel and various work equipment in a vertical direction to test the airtightness of a BOP stack so that they can be stored and used.

In general, in a shipboard drilling ship, BOP (Blow Out Preventer; Explosion Preventer) is a key equipment for drilling work that handles a high pressure of 15,000 psi or more, and requires periodic inspection during storage and stacking in a drilling ship.

The test mandrel is used to test the airtightness of the BOP stack, and is formed in the form of a long tube to penetrate the bore in the center of the BOP during the BOP inspection work. The quantity will be used in the main line.

More specifically, after inserting the test mandrel into the BOP stack, by applying pressure in a state where the ram is in close contact with the outer surface, the airtightness between the test mandrel and the ram or to the lower packing part of the ram is properly maintained. It is used to test whether it has been done.

The test mandrel used to test the airtightness is usually stored in a horizontal state on the surface of the deck of the drilling ship after use.

Usually, the approximate length of the test mandrel is 20 m and the weight is about 1.5 tons. However, when storing the test mandrel lying down on the upper part of the deck, it is difficult to handle because it is long and heavy, and it takes up a lot of space. Storage is very cumbersome and inconvenient due to traffic or interference with other equipment or structures.

In addition, the test mandrel is designed to be transported to the BOP area where one end is lifted by a crane when necessary while lying on the floor, and is exposed to danger due to interference with surrounding installations and structures.

In addition, if the test mandrel is deformed due to collision or breakage during improper storage and transportation, it may lead to defects (defective inspection, etc.) of the BOP equipment itself, so careful management is required.

In addition, since the length is long when properly storing various work equipment such as wires, chains, sling belts, crane forerunners, etc. It is stored in, but when used again, it is tangled in the process of separating from the rolled state and unfolding, which can cause inconvenience in work because it is not easily untied.

In addition, there is a risk that work facilities may be contaminated and damaged when left unattended on the bottom of a ship due to carelessness. Therefore, a means for preventing this phenomenon and for convenience in use has been required.

Republic of Korea Utility Model Registration No. 20-172998 (Announcement date: March 15, 2000)

In addition, shim plates 132d and 133d are formed on inner surfaces of the support portions 132a and 133a of the fixed clamping member 132 and the rotary clamping member 133, respectively, so that they are inserted into and clamped. The contact area with the test mandrel 10 is reduced to prevent damage due to many contacts.

8 is a perspective view showing the second mounting mechanism 200, and FIG. 9 is a cross-sectional side view of the second mounting mechanism 200 of FIG. 8, showing a state in which work equipment is inserted.

As shown in FIGS. 8 and 9, the second mounting mechanism 200 is formed in the vertical direction with a gap in the front of the support 210 formed in the vertical direction and the support 210, and various It may be configured to include a storage tube 220 capable of storing work equipment 300.

The support 210 may be provided in plurality, and a support 212 connected between the supports 210 is formed on the top of the support 210, and the storage tube 220 is forward of the support 212. ) is equipped with a connecting rod 214 that is connected to and supported.

In addition, a support pad 211 may be fixed to a lower end of the support 210 .

Like the support pad 124, the support pad 211 allows the load of the support 210 to be distributed without a concentrated load, thereby protecting the upper surface of the moonpool enclosure structure 300, Convenience can be provided during welding work for fixation.

In addition, as shown in FIG. 8, a plurality of hanging members 213 are formed on the upper surface of the support 212 to protrude, and various equipment 230 stored in the storage tube 220, for example, a chain ( 230) may have a structure in which the hanging member 213 connecting the ring 216 connecting the upper end is formed to protrude.

The storage tube 220 may be formed in the form of a long tube having a predetermined length, has an open upper and lower end structure, and may be provided in a plurality at intervals, and various work equipment 230 therein ), for example, wires, chains, etc. can be inserted and stored in a vertical direction.

In addition, the inner side of the storage tube 220 may be equipped with a fixing table 222 that can be fixed while maintaining a predetermined interval on the wall surface of the munpul enclosure structure 300 to be installed.

In addition, as shown in FIG. 10, for example, in the case of a chain 230 among work equipment in the storage tube 220, the upper end of the chain 230 is a support provided at the rear of the storage tube 220 ( 212) to be detachably connected to the ring 216 provided on the rear side.

The ring 216 is made to be caught on the hook member 213 formed on the upper portion of the support 212.

In FIG. 10 , for convenience, the hook part 216 shows a state right before the hanging member 213 is completely hooked.

According to one embodiment of the present invention, the mounting device 1 can be installed, for example, in the munpul enclosure structure 300 of the drilling rig, as shown in FIGS. 1 and 2, the inside of the munpul enclosure structure 300 A BOP is provided, and a crane is provided nearby so that the test mandrel 10 can be easily handled when using or storing it.

Therefore, when the test mandrel 10 is to be stored, a crane (not shown) is mobilized to erect it vertically and fixed between the support member 110 of the first mounting mechanism 100 and the clamping structure 120. can be stored,

In other words, the support member 110 is located at the lower part and the lower end of the test mandrel 10 is inserted into the insertion hole 112 of the fixing member 132 to be supported, and at the upper part, the test mandrel ( 10) is fixed by clamping the upper part.

The clamping structure 120 is opened by first separating the locking pin 135, rotating the rotary clamping member 133 from the fixed clamping member 132 through the hinge pin 134, and After inserting it into the support part 132a forming a semicircular curve, close the open rotary clamping member 133 so that it comes into contact with the fixed clamping member 132 to form a circle, and extend the separated locking pin 135 again Penetrate and insert through the pieces 132c and 133c to ensure locking.

In this way, the test mandrel 10 can be stored upright in the vertical direction, so it takes up less space, and space that is not used in the drilling rig can be utilized, thereby increasing space utilization and reducing interference during other operations. there is.

In addition, a plurality of first mounting mechanisms 100 may be provided to store and use a plurality of test mandrels 10 .

On the other hand, various equipment used in ships, such as wires, chains, sling belts, etc., are long, so they must be well aligned in order to be used immediately after storage. However, the holding device 1 according to an embodiment of the present invention is provided with the second holding mechanism 200, so that it can be stored and used more easily.

In other words, the second mounting mechanism 200 is provided with one or more storage tubes 220 in the vertical direction, and the work equipment 230, that is, for example, a chain, is inserted into the storage tube 220. can be stored

For the chain, first connect the hook part 216 to the hanging member 213 protruding from the support 212, hang the chain on the valley part 216, insert it into the storage tube 220, and hang it down.

Therefore, when storing various long working equipment 230, it can be stored hanging down vertically, taking up less space, and when used again, it can be pulled out from the inside of the storage tube 220 and used, so it does not get tangled as much It does not cause any inconvenience in use.
