Description

Burner boom structure {Structure of burner boom}

The present invention belongs to the technical field related to the burner boom structure mounted on the oil drilling vessel.

In recent years, as oil drilling has become more active internationally, especially in deep-sea oil field development projects, crude oil drilling ships such as drill ships, rigs, etc. from ship owners are continuously coming to the marine market.

Numerous equipment and facilities are used for various types and purposes of these oil drilling vessels, and the essential equipment that is essential to all oil drilling vessels is a burner boom.

The burner boom is a device that separates the gas and crude oil generated from the oil drilling process and discharges and incinerates it through the piping line. It is an essential equipment for stabilization of the drilling system.

When the burner boom is not in operation, it is seated and fixed in the boom rest installed on the drilling rig deck, and moves to the outside of the drilling rig only when operating, and then releases and burns gas and crude oil.

A high pressure water cooling system is installed at the middle and end of the burner boom to protect the drilling vessel from the high heat generated during combustion.

Prior to commissioning and operating the water cooling system, the first priority should be to ensure that the direction and location of the burner boom is positioned outside the drilling rig through the swivel system. Therefore, the technology of this turning device is one of the most important core technologies in the burner boom.

In FIG. 1, a conventional burner boom turning device is illustrated, and FIG. 2 is a detailed view of the upper foundation 2-1 of FIG. 1, and the upper side of FIG. 2 is a view viewed from the top of FIG. 1 downward. , The lower side figure of FIG. 2 corresponds to a side view of the upper side figure of FIG. 2.

The pivoting device for rotating the boom 1 includes an upper foundation (2-1, upper foundation), cylinders 1 (cylinder # 1, 7) and cylinders 2 (cylinder # 2, 8) and two slabs coupled thereto. The first and second slew bearing rings (slew bearing # 1, 9) and the second slew bearing rings (slew bearing # 2, 10) are formed.

On the other hand, the lower foundation (2-2, lower foundation) is formed under the upper foundation, and one slew bearing (slew bearing) is provided.

1 and 2, when both cylinder 1 and cylinder 2 are in an initial state (non-operational state), the boom 1 is in the 0 degree angle direction in FIG. In this state, when the cylinder 1 is operated in the state where the cylinder 8 is fixed, the slewing bearing 9 is rotated so that the boom 1 pivots in the 90 degree angle direction shown in FIG. .

On the contrary, when the second cylinder 8 is operated while the first cylinder 7 is fixed, the second slewing bearing 10 rotates so that the boom 1 rotates in the -90 degree angle direction shown in FIG. It is the principle of the turning device for the existing burner boom.

As such, when one of the two cylinders is operated in the upper foundation 2-1 of the conventional turning device, the other one of the cylinders must be fixed in order to effectively transmit torque from the operated cylinder. . That is, the conventional turning device requires three slew bearings (two on the upper foundation and one on the lower foundation) as shown in FIG.

By the way, the slew bearing was very difficult and expensive to manufacture, it took a lot of production period, it was very difficult to provide a smooth supply system.

If a problem occurred in the slew bearing, the entire burner boom manufacturing process would have enormous disruptions.

The present invention has been developed in order to reduce the number of slew bearings, and to fundamentally improve the cylinder operation structure installed in the swinging device, and at the same time to provide a technique for preventing corrosion of the cylinder rod and maximizing working convenience of cylinder replacement. present.

The object of the present invention is as follows.

That is, the manufacturing process is difficult and expensive, by installing the number of slew bearings for the burner boom slewing device in a single number to reduce the cost and shorten the production period in the design and manufacture of the entire slewing device. Thus, it is possible to replace the two foundations that had to be manufactured separately in the past with only one foundation to propose a turning device with the advantage that the structure of the pedestal is simplified and downsized.

Next, the distance between the two foundations is too far to match the axis of rotation while adjusting the accuracy (accuracy) was a very difficult task, but to be replaced by a single foundation by the present invention to avoid the task of matching the conventional axis of rotation itself do.

In addition, when the pedestal is manufactured to avoid the existing large cylindrical structure does not require the process of bending, rolling, pipes, etc., the pedestal structure is very simplified to facilitate the manufacturing process and significantly lower the manufacturing cost.

In addition, when the burner boom is not in operation, the cylinder rod is installed at a position not exposed to seawater and dust, so as to improve the convenience of preventing corrosion and maintaining the cylinder.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are not limited to the rights of the present invention, any claims and equivalents of the invention are all put out in advance belongs to the scope of the present invention.

First, the conventional boom structure is briefly described.

The conventional boom structure as shown in FIG. 1 is simplified and shown in FIG. 3, wherein the boom 1 is installed from the left side to the upper right side, and each lower end of the boom 1 has an upper foundation 2-1 and It is combined with the lower foundation 2-2. The upper and lower foundations are connected to one side of the pedestal 3 on the left side, respectively.

In describing each function, the boom 1 serves to hold the piping line 4, and the upper foundation 2-1 is a structure for connecting the upper portion of the pedestal 3 and the boom 1. It includes two slew bearings (9, 10, see Fig. 2) connected up and down to rotate. These slew bearings are connected to cylinders 7, 8 and 2, respectively.

The lower foundation 2-2 is a structure connecting the lower part of the pedestal 3 and the boom 1, and one slew bearing is installed to rotate the boom 1 (see FIG. 1).

In the conventional boom structure, two foundations are arranged up and down, and when installing a total of three slew bearing rings, it is known to be extremely difficult to align the central axis up and down.

However, as shown in FIG. 4, the boom structure of the present invention is configured to pivot the boom 200 only with one foundation 500. This is not just a structural change of the foundation, but significant technological advances in the construction of boom structures, such as reducing the number of slew bearings, eliminating the need for slew bearing alignment, and reducing the time and cost of the entire plant construction.

5 corresponds to an enlarged perspective view of a portion of the foundation 500 of FIG. 4.

The foundation 500 united as one has a slew bearing 540 formed inside the housing 520, and is connected to two parts of the slew bearing to rotate the slew bearing cylinder A for turning the boom 200. , B (570,572) are formed.

The upper end of the slewing bearing is formed with a seating portion 550 for mounting and coupling the pedestal 400 structure, the seating portion is formed to rotate together with the rotation of the slewing ring.

6 illustrates a state in which the housing cover 522 of FIG. 5 is detached. Cylinders A and B are coupled to one side of the slew bearing 540, respectively, and are positioned parallel to the same plane unlike the conventional cylinder arrangement (FIG. 2). In the case of the conventional boom structure, the cylinder for rotating the slewing ring is exposed to the outside air as shown in FIG. 1, so that the contamination of the cylinder by sea water and dust was serious, but in the present invention, the foundation 520 structure Simplified and formed inside the housing 520, to eliminate the possibility of contamination by any sea water or dust.

In FIG. 7, the operating principle of the slew bearing 540 by the cylinders A and B is described. (b) In the figure, the boom 200 is positioned to the right side on the ground, and the rods of the cylinders A and B do not all protrude.

In FIG. 7, BOOM DIRECTION indicates a direction in which the upper end of the boom is facing.

(a) In the figure, cylinder B moves to the right and cylinder A rotates downward to the right with an idle state. This causes the boom to turn counterclockwise from the ground.

(b) In the figure, cylinder A is moving to the right and cylinder B is rotating to the upper right side in an idle state. As a result, the boom pivots clockwise from the ground.

This cylinder operation is completely different from the structure in which the conventional boom structure, when one of the two one cylinders 7 and 8 is operated as shown in FIG. In other words, in the past, the slew bearing rings 9 and 10 were operated by one cylinder.

As shown in FIG. 4, the slew bearing and the cylinder of the present invention are located at the lowermost side of the boom structure, so that the operator can work very easily when maintenance is required, whereas in the past, the upper foundation 2-1, 1) To repair the cylinder formed in the position had to work at high altitude in this case, there was a problem such as safety accidents and work efficiency reduction.

Hereinafter, the pedestal shown in FIG. 8 will be described. As described above, the pedestal 400 is a structure that connects the foundation and the boom.
As seen in FIG. 8, the pedestal 400 is a hexahedral lattice structure (truss structure), and from the upper side to the lower side of the lattice structure part of one vertical plane (part C) among several surfaces of the pedestal which is a hexahedral structure as a whole. , The lower ends of the boom 200 are coupled.

Pedestal 400 of Figure 8 is coupled to the seating portion 550 is rotated in accordance with the operation of the slewing bearing, one side is coupled to the boom 200 structure.

Compared to the pedestal of the conventional boom structure (see FIGS. 1 and 3), the pedestal 400 of the present invention is very simple and the manufacturing process is simple, which greatly reduces the cost and manufacturing period.

In other words, the previous pedestal (3) shown in Figs. 1 and 3, in order to bind with the upper and lower foundations (2-1, 2-2), the height and scale were very large, such a pedestal In order to fabricate the process, such as bending, rolling, and tubing for the pedestal material was required.

However, as shown in FIG. 4, the pedestal structure (FIG. 8) of the present invention is formed such that the linear metal structure is formed in a lattice shape, and the boom 200 structure is formed to be inclined at one side of the pedestal.

By the way, the boom 200 structure from one side upper side to the lower side of the pedestal should be formed to be coupled to the pedestal so as to withstand the rotational moment (the moment in the direction in which the boom falls) by the weight of the boom inclined.

Since the pedestal 400 of the present invention may be combined in a state in which one small foundation 500 is seated, the left and right widths and heights are very small, and unlike the past, the pedestal 400 does not need to be bent and rolled. Since the process is very easy, the installation cost is very reduced.

Meanwhile, the piping line 300 collectively refers to a passage through which waste gas passes when the waste gas is discharged and a passage through which water passes when the water cooling system operates.

The effects exhibited from the present invention are as follows.

First, since the manufacturing process is difficult and expensive, only one number of slew bearings for the turning device of the burner boom may be installed, the effect of cost reduction and shortening the manufacturing time in the design and manufacture of the turning device is remarkable. In addition, it is possible to replace the two foundations that had to be manufactured separately in the past with only one foundation, there is an advantage that the structure of the pedestal is simplified and downsized.

Next, the task of matching the rotational axis while adjusting the accuracy was too difficult since the distance between the two previous foundations was very difficult, but the operation of matching the conventional rotational axis itself is not necessary as it is replaced by one foundation by the present invention. There is an advantage.

In addition, there is no need for bending, rolling, pipework, etc., because the existing cylindrical structure is avoided even when the pedestal is manufactured, and the pedestal structure is very simple, which makes the manufacturing process easier and the manufacturing cost is significantly lowered.
