Description

Floating structure {FLOATING STRUCTRUE}

The present invention relates to a floating structure with an eyepiece.

In recent years, the use of floating structures capable of performing drilling and other operations at sea has been greatly increased by installing drilling equipment and the like. Floating structures can be operated in the transit mode and the jackup mode depending on the operation characteristics. Specifically, the floating structure moves to the navigation mode to the position where the operation is desired. In sailing mode, the legs can be moved upward to reduce resistance by seawater. The floating structure is then switched to the jack-up mode, the legs are lowered into the sea bed, and then the body is lifted along the legs so that the body is spaced a certain distance from the sea level. When the main body reaches the predetermined position, the floating structure stops the movement of the main body and installs an offshore wind power generator. When the operation is completed, the main body moves in the reverse order to move to the next installation position .

Because these floating structures perform operations for a long time at sea, they are supported by food and equipment using supply vessels as needed. However, when the float-type structure is in the jack-up mode, since the body is floated from the sea level, the operation support line approaching the float-type structure is not suitable. As a result, it is very difficult to maintain the stability and position of the work support line during the work of transporting food and equipment from the work support line to the floating structure. There is also the risk of collapsing the floating structure if the work support line, etc., collide with the legs because they can not maintain their position.

[ For example, one end of the eyepiece platform 100 is hinge-coupled to the side of the main body 11 so that the eyepiece platform 100 can rotate in a direction parallel to the plane forming the side surface of the main body 11, .

In this embodiment, the docking platform 100 may be made of a structure having a predetermined length extending from one end hinged to the main body 11. For example, the docking platform 100 may be formed of various types of structures such as a cylinder, a square truss structure, and a triangular truss structure. In this embodiment, the docking platform 100 is formed as a rectangular truss structure, but the present invention is not limited thereto. Further, the docking platform 100 may be formed to have a rigidity enough to withstand a load applied when mooring support lines or the like are moored thereto, and when the docking platform 100 is lowered to the main body 11, And a structure having a predetermined length extending from one end of the hinge coupling 112 with the main body 11 so as to be positioned near the main body S of the main body 11. [

A hinge protrusion 110 may protrude from the one end of the eyepiece platform 100 and the hinge protrusion 110 may be rotatably inserted into a side surface of the main body 11 to form a hinge joint 112 . For example, the hinge protrusion 110 inserted into the main body 11 may be connected to a driving unit 300 that provides a driving force for rotating the docking platform 100, as described later. In this case, as the driving unit 300 rotates the hinge protrusion 110, the remaining structure of the docking platform 100 connected to the rotation protrusion can be rotated. Alternatively, the driving unit 300 may be installed outside the main body 11 and connected to other parts of the docking platform 100. In this case, the hinge protrusion 110 inserted into the main body 11 can act only as a rotating shaft have.

3, the eyepiece platform 100 is fixed and held in parallel with the main body 11 on the side surface of the main body 11, and is rotated in one direction, if necessary, Lt; / RTI > In this case, the docking platform 100 is formed to extend from the end coupled with the main body 11, and the docking platform may protrude to the lower portion of the main body 11 and extend to the sea level S , And its end may be located near the sea level (S). When the use is completed, the eyepiece platform 100 can be raised again in parallel with the main body 11 by further rotating in the one direction or rotating in the opposite direction.

When the docking platform 100 is lowered to the lower side of the main body 11, the docking platform 100 can act as a docking station for the operation support line 2 approaching the floating structure 1. The work support line 2 can be maintained in its restoring force and its position by mooring on the docking platform 100 by using the mooring line 21 after riding on the docking platform 100. [

According to one embodiment, the one end of the eyepiece platform 100 may further include a guide protrusion 120 protruding in the same direction as the hinge protrusion 110. At this time, the guide protrusion 120 may be formed at a position apart from the hinge protrusion 110, and the side of the main body 11 may be provided with a guide protrusion 120, A guide groove 1101 which can be guided can be formed. The eyepiece platform 100 may be installed in the main body 11 such that the guide protrusion 120 is inserted into the guide groove 1101. When the eyepiece platform 100 rotates, The movement of the guide protrusion 120 can be guided by moving along the guide groove 1101 while being inserted into the guide protrusion 1101.

As shown in FIGS. 3 and 4, the guide groove 1101 may be formed in the form of a slit extending in a long direction. Specifically, the guide groove 1101 may be formed around a point where the hinge protrusion 110 of the eyepiece platform 100 is inserted And may be in the form of a slit extending along one circle. The radius of the circle may be equal to the distance between the hinge protrusion 110 and the guide protrusion 120. Accordingly, when the eyepiece platform 100 rotates about the hinge protrusion 110, the guide protrusion 120 can be moved along the guide groove 1101 while being inserted into the guide groove 1101.

A roller ball 122 may be provided at the end of the guide protrusion 120 and the roller ball 122 may reduce the frictional force when the guide protrusion 120 moves in the guide groove 1101. [

The guide protrusion 120 is inserted into the guide groove 1101 so that the eyepiece platform 100 can be coupled to the main body 11 by the guide protrusion 120 as well as the hinge protrusion 110. [ As a result, the connection between the docking platform 100 and the main body 11 becomes more rigid, and the docking platform 100 can be supported more stably.

The cushioning member 200 may be provided at the other end of the docking platform 100 and may be made of a member capable of absorbing impact when the docking platform 100 hits the work support line 2, have. For example, the buffer member 200 may be a rubber tube filled with air. The cushioning member 200 may have a larger cross-section than the cross-section of the docking platform 100 so as to effectively absorb an impact upon collision of the work support line 2 and the like. That is, the buffer member 200 may be formed in a size and shape that protrudes further outward than the outer circumferential surface of the eyepiece platform 100.

The cushioning member 200 fixed to the other end of the docking platform 100 can be moved up and down with respect to the main body 11 by rotating the docking platform 100 around one end thereof. When the diving platform 100 is rotated and lowered to the lower side of the main body 11, the buffer member 200 can be in contact with the sea surface S. The cushioning member 200 may be spaced apart from the sea surface S by a predetermined distance in a state in which the diving platform 100 is raised in parallel with the main body 11. [

3, the cushioning member 200 may be provided with an impact sensor 400, and the cushioning member 200 may be configured such that when the impact sensor 400 senses an impact And may be configured to expand. Specifically, when the docking platform 100 is lowered to the lower side of the main body 11 and the buffering member 200 is in contact with the sea surface S, the impact detection sensor 400 detects the impact between the buffering member 200 and the sea surface S Can be detected. The buffer member 200 may be maintained in a contracted state at a predetermined distance from the sea surface S and may be configured to expand when the impact detection sensor 400 senses an impact.

Although not shown in the drawing, the floating structure 1 of the present embodiment includes an air injection unit such as a bomb, which is provided for injecting air into the buffer member 200, and an air injection unit for connecting the air injection unit and the buffer member 200 The air tube may be further included. The air injection unit may be controlled to discharge the compressed air to the air tube when the impact sensor 400 senses an impact. The discharged compressed air is transferred to the buffer member 200 through the air tube, and the buffer member 200 can be expanded. The air injection unit may be installed in the eyepiece platform 100 or the main body 11.

The driving unit 300 may be installed in the main body 11 to provide a driving force for rotating the docking platform 100. For example, as shown in FIG. 2, the driving unit 300 may be installed inside the main body 11 and may be connected to the hinge projections 110 of the eyepiece platform 100. In this case, the driving unit 300 may include a rotational power source and one or more gears mechanically connected to the rotational power source, and the hinge protrusion 110 may be rotated by being mechanically connected to the gear. As the hinge protrusion 110 is rotated, the truss structure integrally connected thereto can be rotated.

As another example, although not shown, the driving unit 300 may include a winch installed on the top or side of the main body 11, and a cable wound and unwound by the winch. In this case, the cable may be connected to the truss structure of the docking platform 100. And may be connected to the opposite end of the hinge protrusion 110 of the truss structure. As the winch rotates, the cable is wound and unrolled, so that the end of the truss structure can be raised or lowered. As a result, the truss structure can be rotated about the hinge protrusion 110. [

In the present embodiment, the floating structure 1 in the jack-up state can be operated in the standby mode and the eyepiece mode. The standby mode is a state in which the docking platform 100 is fixed such that the buffer member 200 is spaced a predetermined distance from the sea level S and the floating structure 1 It can be operated in standby mode. The riding mode is a state in which the docking platform 100 is held such that the damping member 200 is in contact with the sea surface S and the floating support structure 1 is in a state in which the operation support line 2 approaches and needs mooring It can be operated in the eyepiece mode.

Specifically, in the idle mode, the docking platform 100 can be fixed on the side of the main body 11 in a state that the docking platform 100 is parallel to the main body 11 by the driving unit 300, The buffer member 200 provided at the end may be maintained at a predetermined height from the sea surface S. The diving platform 100 is not limited to being held parallel to the main body 11 and the diving platform 100 and the main body 11 ) Is not limited. The driving unit 300 can block the rotation of the docking platform 100 and fix the docking platform 100 in a raised state.

When the work support line (2) approaches, the floating structure (1) can switch to the riding mode and lower the riding platform (100) to the lower side of the main body (11). Switching to the eyepiece mode may be accomplished by rotating the eyepiece platform 100 by the driver 300.

In the docking mode, the docking platform 100 can be held downwardly of the main body 11. At this time, the docking platform 100 may be substantially perpendicular to the main body 11 and protrude to the lower portion of the main body 11 to extend to the sea level S. However, the docking platform 100 may have an angle The present invention is not limited thereto. As the docking platform 100 is lowered, the buffer member 200 provided at the end of the docking platform 100 can come into contact with the sea surface S.

When the floating structure 1 is operated in the docking mode, the docking platform 100 can connect the main body 11 and the sea surface S as described above. That is, the docking platform 100 may be provided as a structure substantially perpendicular to the sea level S outside the side surface of the main body 11, and the docking platform 100 may be provided as a structure approaching the floating structure 1 The work support line 2 can be a supporting stand capable of mooring.

Accordingly, the work support line can be stably moored to the floating structure 1, and the restoring force and the position thereof can be effectively maintained when the food and equipment are transported to the floating structure 1. At this time, the cushioning member 200 provided at the end of the docking platform 100 can prevent the work support line 2 from colliding with the docking platform 100 and being damaged. Since the docking platform 100 is positioned between the work support line 2 and the leg 12 of the floating structure 1 so that the work support line 2 collides with the leg 12, It is possible to prevent the stability of the cooling structure 1 from being threatened.

When the transportation of food and equipment is completed and the work support line (2) leaves, the floating structure (1) can be switched to the standby mode again. To this end, the driving unit 300 may rotate the docking platform 100 until it is parallel to the main body 11. Then, the driving unit 300 may block the rotation of the docking platform 100 to fix the buffer member 200 in a state of being spaced apart from the sea surface S by a predetermined height.

According to one embodiment, the cushioning member 200 is configured to float on the water, and the driving unit 300 may allow rotation of the docking platform 100 in the dock mode. For example, unlike in the idle mode, the driver 300 may be allowed to rotate freely without blocking rotation of the docking platform 100 in the docking mode.

The cushioning platform 200 provided at the other end of the dipping platform 100 can be held on the sea level surface S ). ≪ / RTI > The height of the other end of the docking platform 100 is changed by the cushioning member 200 and the height of the other end of the docking platform 100 is changed by the height of the sea level S, Can be rotated. That is, in this embodiment, when the height of the sea level S of the portion where the docking platform 100 is lowered changes, the docking platform 100 having a flexible supporting structure whose angle changes according to the change Can be provided.

The docking platform 100 having such a flexible supporting structure can efficiently absorb the movement of the sea level S which changes due to waves or the like. For example, if the height of the sea level surface S changes due to the waves hitting, the docking platform 100 is also rotated together with the docking platform 100 so that damage to the docking platform 100 due to the kinetic energy of waves can be prevented . Further, when the height of the sea level S changes, the work support line 2 or the like supporting the mooring platform 100 moves up and down. However, since the mooring platform 100 also rotates and moves up and down, Kinetic energy due to the motion of the support line 2 can also be effectively absorbed.

2 and 4, the floating structure 1 is protruded obliquely from the lower surface of the main body 11, and in the riding mode, the main body 11 of the docking platform 100, And a supporting member 500 for supporting the side surface. The upper end of the support member 500 may be fixed to the body 11 and the support member 500 may extend outwardly of the floating structure 1 so that the lower end can support the side of the docking platform 100 . The lower end of the support member 500 can be in contact with the side surface of the eyepiece platform 100. Alternatively, the lower end of the support member 500 may be spaced a predetermined distance from the docking platform 100. In this case, when the docking platform 100 is pushed to the inside of the floating structure 1 by an external impact or the like, the lower end of the supporting member 500 can come into contact with the side surface of the docking platform 100.

The support member 500 supports the side surface of the docking platform 100 to enhance the stability of the docking platform 100 in the docking mode. Particularly, when the work support line 2 collides with the docking platform 100 or the damping member 200, the docking platform 100 is subjected to the force of being pushed inward of the floating structure 1. In the eyepiece mode, since the eyepiece platform 100 is coupled to the main body 11 only at the upper end thereof, the joining portion can be made vulnerable to the pushing force as described above. In addition, if the docking platform 100 is pushed inward by the pushing force, the stability of the work support line 2 moored on the docking platform 100 may be affected. In this embodiment, since the support member 500 supports the docking platform 100 from the inside, stability can be maintained even when the docking platform 100 is subjected to a force to be pushed as described above.

Hereinafter, a floating structure 1a according to another embodiment of the present invention will be described with reference to FIG. However, since the present embodiment differs from the above-described embodiments in that the support groove 130 is formed in the docking platform 100, differences will be mainly described, and the same portions will be described with reference to FIGS. The description and the reference numerals are used.

5 is a side view showing a floating structure 1a according to another embodiment of the present invention.

5, in a floating structure 1 a according to another embodiment of the present invention, a supporting member 500a, to which an end of the supporting member 500a can be inserted, (130) may be formed. The support groove 130 may be formed at a position corresponding to the end of the support member 500a. For example, the support groove 130 may be formed at a position where the end portion of the support member 500a is inserted into the floating platform 100 when the platform 100 is pushed inward by a predetermined distance by an external impact or the like . In this case, when the eyepiece platform 100 is not pushed, the support member 500a may not be inserted into the support groove 130.

In this embodiment, a roller ball 510 may be provided at the end of the support member 500a. The roller ball 510 is supported by the support members 500a and 500b when the end of the support member 500a is inserted into the support groove 130 or when the end of the support member 500a is inserted into the support groove 130 The frictional force between the docking platforms 100 can be reduced.

When the supporting platform 130 is formed on the docking platform 100 as described above, when the docking platform 100 is pushed, the supporting member 500a is inserted into the supporting groove 130, Can be effectively supported. When the support member 500a is inserted into the support groove 130, the support member 500a can effectively fix the position of the ridge platform 100, and thus the ridge platform 100 is pushed in the direction Is limited. Therefore, when an external impact or the like occurs in the docking platform 100, the docking platform 100 can be more stably supported.

While the present invention has been described with respect to specific embodiments of the floating structure according to the embodiments of the present invention, it should be understood that the present invention is not limited thereto, and should be construed as having the widest range according to the basic idea disclosed in this specification do. Skilled artisans may implement a pattern of features that are not described in a combinatorial and / or permutational manner with the disclosed embodiments, but this is not to depart from the scope of the present invention. It will be apparent to those skilled in the art that various changes and modifications may be readily made without departing from the spirit and scope of the invention as defined by the appended claims.
