Description

TECHNICAL FIELD [0001] The present invention relates to a guide for guiding the mounting of a turret cylinder, and a method for mounting the turret cylinder. BACKGROUND OF THE INVENTION 1. Field of the Invention < RTI ID =

The present invention relates to a guide for guiding the mounting of a turret cylinder and a turret cylinder mounting method using the same.

Generally, a turret is provided in the FPSO (floating oil production storage and unloading facility) for collecting gas or crude oil from the seabed.

The turret is usually divided into an upper turret and a lower turret, of which the lower turret is usually mounted on the vertical opening of a caisson provided at one end, usually the forefront of the vessel, and a subsea well platform So that the ship is moored. Such a lower turret is also referred to as a turret cylinder, and the upper turret may be mounted on the lower turret, that is, above the turret cylinder.

Further, the turret cylinder is installed so that the ship can rotate around the turret cylinder. Namely, the turret cylinder is fixed to the platform of the submarine, and a sliding bearing is interposed between the turret cylinder and the caisson of the ship, so that the ship can rotate naturally around the turret cylinder by the action of wind, algae or blue . This allows the gas or crude oil to be stably transported to the ship side through a pipe or the like in the fixed turret, even if wind, tide or wave acts during the drilling operation.

The inner wall of the caisson in contact with the bearing is required to have rigidity enough to withstand the load exerted upon rotation of the turret. Typically, the bearing for the turret includes an upper vertical bearing, an upper horizontal bearing, And can be roughly divided into a horizontal bearing (Lower Horizontal Bearing).

Here, the upper horizontal bearing mainly supports the horizontal load generated by the horizontal flow of the ship, and may be disposed below the upper and upper vertical bearings of the caisson.

The upper horizontal bearing may be spaced apart from the upper portion of the caisson in a circumferentially surrounding structure of the turret cylinder, wherein the upper horizontal bearing may be inserted into the bearing housing and fixedly mounted on the upper bearing seat.

The lower horizontal bearing may be spaced apart from the lower portion of the caisson in a circumferential manner so as to surround the turret cylinder, and the lower horizontal bearing may be fixed to the lower bearing seat provided below the turret cylinder.

Meanwhile, in order to mount the turret cylinder manufactured outside the caisson in the vertical opening of the caisson, the turret cylinder is lifted by a crane or the like, and then positioned above the vertical opening. Then, the turret cylinder is gradually lowered to the vertical opening, and the turret cylinder having been mounted is brought into contact with the above-mentioned upper vertical bearing, upper horizontal bearing and lower horizontal bearing.

A predetermined guide is required to mount the turret cylinder stably in the vertical opening of the caisson. When the turret cylinder is inclined in one direction during the turret cylinder mounting process, there is a possibility that the fittings installed in the turret cylinder are damaged. When the turret cylinder rotates along the circumferential direction of the turret cylinder, It may be difficult for the riser to be connected to the turret cylinder.

That is, if both the first display and the upper ends of the four location bars 127 are matched, it can be determined that there is no inclination to the turret cylinder 50, and the turret cylinder 50 can be continuously lowered. On the other hand, if the top of some location bar 127 matches the first mark, but the top of the remaining location bar 127 does not match the first mark, the turret cylinder 50 may be seen as tilted to one side , Measures can be taken to correct this.

In the state where the turret cylinder 50 is not tilted, the position bar 127 is positioned between the second indication and the third indication. In the process of mounting the turret cylinder 50, 2 display or the third display, it can be seen that the turret cylinder 50 is tilted to one side, and measures for correcting it can be taken. In addition, when the entirety of the location bar 127 is located in parallel with the second and third displays, but located outside the second and third displays, the turret cylinder 50 may be regarded as rotating in the circumferential direction, Measures can be taken to correct this.

11 is a flowchart of a turret cylinder mounting method according to an embodiment of the present invention.

First, a guide is installed at a plurality of places of the caisson 10 (S10). In this embodiment, the first guide 100 is installed on a part of the upper horizontal bearing installation portion above the caisson 10, And the second guide 110 is installed on a part of the lower horizontal bearing mounting portion of the lower portion. The third guide 120 may be further provided on the turret supporter 12 disposed on the uppermost portion of the caisson 10 as required.

When the installation of the guide is completed, the bearing may be installed (S20). For example, an upper horizontal bearing may be installed in a place where the first guide 100 is not installed in the upper horizontal bearing installation portion on the upper part of the caisson 10, 2 lower guide may be installed at a place where the guide 110 is not installed. Also, the pad may be installed in a place where the third guide 120 is not installed in the turret support portion 12 at the top of the caisson 10.

The step of installing such bearings or pads may be performed before the guide installation step, depending on the working environment.

After the installation of the guide is completed, a display may be provided at a position corresponding to the guides 100, 110, and 120 in the outer surface of the turret (S30). As described above, this is for confirming whether or not the turret cylinder rotates in the circumferential direction of the turret cylinder during the loading process of the turret cylinder or whether it is inclined.

Next, the turret cylinder can be gradually lowered (S40) to the vertical opening 11 of the caisson 10 while confirming the circumferential rotation of the turret cylinder.

When the lowering (mounting) of the turret cylinder is completed, the guides 100, 110, and 120 may be removed, and a bearing or a pad may be installed at that position (S50). Specifically, the upper horizontal bearing is installed in a place where the first guide 100 is installed, the lower horizontal bearing is installed in a place where the second guide 110 is installed, and the lower horizontal bearing is installed in a place where the third guide 120 is installed. Respectively.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. It will be understood that various changes, modifications, or substitutions may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
