Abstract
A turret bearing arrangement is disclosed which is capable of selectively rotating the turret while supporting the rails of the turret in the hull.
The bearing device of the turret may be installed to face the guide rails of the turret, and may include a drive bearing for contacting the guide rails to rotate the turret, and a support bearing for supporting the guide rails.
Description
The present invention relates to a bearing device for a turret, and more particularly to a bearing device for a turret capable of supporting and rotating the turret.
Floating offshore structures such as drilling rigs or FPSOs (floating oil production warehousing and storage facilities) can be stored in turrets, such as oil, natural gas, etc., .
The turret may be fixed to a subsea well platform by a chain or the like to moor the floating structure, wherein the floating structure can be relatively rotated about the turret as a central axis.
For example, in the case of drilling or mining crude oil or gas, even if the marine vessel is driven by wind, waves or algae, the vessel can freely rotate around the turret as a central axis, And the like.
The turret can usually be mounted in a vertical opening or moon pool provided at one end of the ship, usually at the forefront. And the turret can be rotated by sliding contact through the hull and the bearing. In one example, the turret may be supported by an upper vertical bearing, an upper horizontal bearing, and a lower horizontal bearing.
In order to mount the turret on the hull and rotate it, it is necessary to verify the rotation function of the turret before mounting the turret on the hull. In order to verify the rotating function of the turret, conventionally, there has been proposed a method of rotating the turret by using a rotating device such as a hydraulic cylinder after placing the turret on the rotating member.
However, according to this conventional technique, it takes a long time to rotate the turret one time, because the angle at which the turret rotates when the hydraulic cylinder is operated once is very small. Consequently, the turret rotates to verify the turret rotation function The test time can be increased.
Embodiments of the present invention provide a bearing device for a turret capable of implementing a rotating test of a turret.
According to an aspect of the present invention, there is provided a bearing apparatus for a turret for supporting a turret in a hull, comprising: a drive bearing installed to face a guide rail of the turret and contacting the guide rail to rotate the turret; And a support bearing for supporting the guide rail.
At this time, the support bearing and the drive bearing may be arranged alternately along the inner circumference of the door frame provided on the hull.
Further, the drive bearing includes a drive wheel for supporting the guide rail; A driving supporter in which the driving wheel is rotatably mounted via a rotating shaft; And a drive unit including a rotary gear connected to one end of the rotary shaft, a drive motor for providing a drive force to the rotary shaft, and a gear box for transmitting the drive force of the drive motor to the rotary gear .
The driving bearing may further include a braking unit connected to the other end of the rotating shaft, and a braking unit including a brake for selectively braking the braking wheel.
Further, the gear box includes a driving gear interlocked with a driving shaft of the driving motor; At least one driven gear rotating around the driving gear; And a ring gear in which a first thread engaging with the driven gear is formed on an inner diameter surface and a second thread engaged with a rotating gear of the rotating shaft is formed on an outer diameter surface.
Further, the support bearing includes a support wheel for supporting the guide rail; And a mounting supporter in which the supporting wheel is rotatably mounted via a supporting shaft.
Further, the support bearing may include a power generating unit that generates rotational energy when the support shaft rotates and generates electrical energy.
Embodiments of the present invention can quickly and easily perform a rotating test of a turret by selectively rotating the turret while supporting the guide rails of the turret in the hull so that a separate rotating testing device for rotating the turret There is an advantage that it is unnecessary.
Further, the embodiments of the present invention have an advantage in that, when the hull is rotated with the turret as a rotation axis, electric power that can be used in the hull can be produced by using the generated rotational force.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
The turret applied in the following embodiments can be defined as a structure connecting the floating ocean structure and the riser, and the floating floating structure can be defined as a drill ship, a floating production, storage, and offloading unit And a hull having a turret.
The turret in which this embodiment is used can be applied to special lines such as drill rigs or FPSO, but the turret can be applied to other types of ships other than the special ship, considering that the floating marine structure includes the range of the vessel.

As described above, the present invention can easily perform the turret rotation test by selectively rotating the turret while supporting the guide rails of the turret in the hull. Accordingly, there is no need for a separate rotating test device for rotating the turret, and electricity can be produced by using the rotational force generated when the hull is rotated with the turret as a rotation axis.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, the same is by way of illustration and example only and is not to be taken by way of limitation, and is to be accorded the widest scope consistent with the basic idea disclosed in the specification.
