Description

{Floating marine structures}

The present invention relates to a floating offshore structure, and more particularly, to a floating offshore structure capable of performing respective functions by simultaneously providing a mooring device and a caisson on one side of a floating offshore structure.

In general, offshore structure can be divided into fixed type and floating type. The fixed offshore structure may consist of a support angle fixed directly or indirectly to the seabed, and an equipment deck supported by the support angle. While stationary offshore structures are stable, they can be used at relatively shallow depths of less than about 150 meters. Floating offshore structures are used at relatively deep water depths of about 152 m or more, and can be fixed on top of a well site by a power line installed on a mooring line or structure fixed to the sea floor. These floating offshore structures can be installed at deeper water depths compared to fixed offshore structures and have the advantage of being easy to move to other wells. The floating offshore structure may be a drill ship, a semi-submersible, a sparged platform, a tension-leg platform, or the like.

Floating offshore structures include mooring equipment that fixes the mooring ropes to the buoys or seams of the offshore structures to fix movements from algae, waves, winds, etc., Anchoring equipment is provided to secure the anchor and the anchor chain through the gripping force at a predetermined position.

In addition, the offshore structure is equipped with a caisson as means for seawater to be used for the topside of the crude oil production and storage facility at the top, or for seawater for cooling of the topside equipment.

Pipe-shaped caissons are connected to an offshore structure to be submerged below the waterline, where the seawater is collected by the pump.

Floating marine structures include various devices, including mooring devices or caissons, which can reduce the space available for offshore structures.

1 and 2, the floating offshore structure according to one embodiment of the present invention includes a mooring device 10 for mooring the vessel 1 and a caisson 20 provided for collecting seawater. .

The mooring device 10 includes a chain 11 fixed at the bottom of the mooring facility or bottom of the sea to be installed at the sea bottom, a support wheel 12 supporting the chain 11, A fixing part 13 which rotatably supports the supporting part 14 and is provided with a hinge part 13b and is rotatable and a fixing part 13 which fixes the fixing part 13 or the hinge part 13b to the structure And a plurality of brackets (15).

FIG. 3 is a side view schematically showing a mooring device 10 and a caisson 20 according to an embodiment of the present invention, and FIG. 4 is a plan view showing a cross section taken along line A-A of FIG.

3 and 4, the concrete structure of the mooring apparatus 10 and the caisson 20 according to the embodiment of the present invention will be described in detail.

As shown in Figs. 3 and 4, the chain 11 is fixed at one end to the ship 1 and at the other end to the mooring facility of the seabed, or further provided with an anchor to be fixed to the bottom surface of the seabed. The chain (11) can be wound into the ship (1) or unwound by the sea bed to moor the ship (1) as required.

The chain (11) is provided on one side or the multiple side of the ship (1) to improve the mooring performance of the ship (1).

The support wheel 12 is rotatably provided so as to stably support the chain 11 when the chain 11 is wound or unwound. The support wheel 12 supports the chain 11 so as to be spaced apart from the ship 1 so as to prevent friction and damage with the ship 1 when the chain 11 moves, It is possible to prevent frictional contact with other structures to prevent damage to the chain 11 as well as improve mobility.

The support portion (14) rotatably supports the support wheel (12). One end of the support portion 14 supports the center of both sides of the support wheel 12. [ At this time, the support pin 14a can hinge the one end of the support portion 14 and the support wheel 12. But may be provided with various bearings other than the support pins 14a.

The other end of the support portion 14 is rotatably fixed to one side portion of the fixing portion 13. At this time, one side of the fixing portion 13a and the supporting portion 14 of the fixing pin 13a are hingedly fixed by the fixing pin 13a. The supporting part 14 is provided on the fixing part 13 so as to be vertically rotatable so that it is possible to improve the moving performance of the chain 11 when the chain 11 moves and the vessel 1 or the chain 11 The strength of the pressing force exerted by the chain 11 on the structure can be reduced even if there is a vertical movement. Further, since the support portion 14 is provided on the fixing portion 13 so as to be vertically rotatable, the structural stability of the ship 1 and the mooring device 10 can be secured.

The fixing portion 13 has a supporting portion 14 fixed to one side portion and a hinge portion 13b provided on the other side portion so as to be rotatably hinged about a rotation axis of the hinge portion 13b.

The fixing portion 13 is provided with the hinge portion 13b and is rotatable in the right and left direction so that even when the ship 1 or the chain 11 is moved by the tide, And damages due to the pressurization of the chain 11 whose end is fixed to the seabed can be prevented. That is, structural stability of the ship 1 and the mooring apparatus 10 can be ensured also by the pressure of the chain 11.

In addition, the rotation axis of the hinge portion 13b is provided on the same axis as the caisson 20, and the concrete structure of the caisson 20 in this regard will be described later.

The bracket 15 fixes both ends of the hinge portion 13b to one side of the ship 1. A plurality of brackets 15 may be provided and the hinge portions 13b may be fixed to the ship 1 by various methods such as welding or bolting.

The caisson 20 is provided so as to extend from the ship 1 to the seabed to take seawater. The caisson 20 is provided with a piping extending in the longitudinal direction and formed with a high-quality portion. The caisson 20 can receive seawater through the hollow portion 21 or discharge the generated water from the ship 1.

The caisson 20 according to the embodiment of the present invention is provided with the caisson 20 having the single hollow portion 21 and the single pipe 20 but only the hollow portion 21 is provided in the hollow portion 21, So that a double piping can be provided. Accordingly, the outer passage may discharge the generated substance from the ship 1, and the inner passage may receive the seawater.

The caisson 20 is provided on the same axis as the rotation axis of the hinge portion 13b, as mentioned above. That is, it can be seen that the rotation center axis of the hinge portion 13b extends through the caisson 20 and extends. In other words, it can be explained that the hinge portion 13b is provided on the outer surface of the caisson 20 by surrounding the caisson 20. The caisson 20 is provided on the outer surface of the caisson 20 with the fixing portion 13, (10) is installed.

The bracket 15 for fixing the hinge portion 13b to one side of the ship 1 can simultaneously perform the function of fixing the caisson 20 to the ship 1 as well as the hinge portion 13b.

A pump (not shown) may be provided inside the caisson 20 or at one side of the caisson 20 as means for taking in seawater, i.e., for raising seawater. The seawater drawn by the pump can be moved through the hollow portion 21 and stored in the vessel 1.

As described above, since the caisson 20 is provided coaxially with the rotation axis of the hinge shaft of the mooring device 10, the space occupied by the mooring device 10 and the caisson 20 in the ship 1 can be reduced. Thus, a space for securing other facility structures can be secured by securing a space in the vessel 1, or a work space for performing necessary work in the vessel 1 can be secured.

In addition, by providing the mooring apparatus 10 and the caisson 20 at the same position, it is possible to reduce the material and manufacturing cost by using less reinforcing structure for fixing to the ship 1.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
