Description

Technical Field

[0001] This application relates to the technical fields of offshore wind power and ocean engineering, and particularly to a temporary mooring system for installing a floating wind turbine onto a floating platform. Background Art

[0002] Currently, offshore wind power mainly relies on fixed wind turbine platforms (or called wind turbine foundations). However, the sea areas suitable for fixed wind turbine platforms are limited. The construction of far - sea wind power will transition from the shallow - water range with a water depth of 30m to 50m to the far - sea waters with a water depth of more than 50m. The increase in water depth will make fixed foundations uneconomical, and floating platforms that are insensitive or even more adaptable to the increased water depth will become a foundation form with important prospects.

[0003] Currently, various floating wind turbine platforms built in the world are moored at the dockside for the installation operation of floating wind turbines. The primary problem faced by mooring a floating wind turbine platform at the dockside for installation is that suitable docks for installing large - scale floating wind turbines are becoming increasingly scarce. Docks suitable for installing large - scale floating wind turbines need to meet the following conditions: 1) A large crawler crane or ring - rail crane needs to be positioned at the dockside to form a fixed hoisting foundation, and the dock front must be a dock foundation with high bearing capacity; 2) The floating wind turbine platform needs to berth at the dock, and the water depth at the dock front should meet the design requirements of the wind turbine platform, generally exceeding 10m; 3) The dock should not be too far from the installation site of the offshore floating wind turbine to avoid long - distance integrated towing operations of the platform and the wind turbine; 4) When installing a floating wind turbine, the motion requirements for the foundation platform are extremely high, and there needs to be a long - term installation window without surges at the dockside. Docks meeting the above conditions are not only extremely expensive to build, but also suitable docks for lease are becoming increasingly scarce.

[0004] In the field of floating wind turbine installation, another problem currently faced is how to prevent typhoons or other adverse weather during the wind turbine installation stage. This problem is not very serious for one or a small number of prototype projects, as the wind turbine installation can be carried out during the typhoon - free season. However, for an entire wind farm (where multiple wind turbines need to be installed), due to the long installation period, it is difficult to avoid the entire typhoon season or all adverse weather. Summary of the Invention

[0005] Based on this, it is necessary to provide a temporary mooring system for installing a floating wind turbine onto a floating platform, aiming to solve the problems in the prior art of relying on docks and lacking typhoon resistance.

[0006] The present application provides a temporary mooring system for installing a floating wind turbine on a floating platform, which includes a floating platform, a pile-leaning assembly, a mooring post assembly, and an anchor assembly. The floating platform includes first, second, and third side columns arranged at intervals, wherein the first side column and the second side column are distributed along a first direction, and the side surface between the first side column and the second side column is a leaning surface, and the third side column is arranged along a second direction perpendicular to the leaning surface; the pile-leaning assembly includes a berthing pile fixed to the bottom of the water. The berthing pile is located between the first side column and the second side column in the first direction and on the side of the leaning surface away from the third side column. The berthing pile is detachably connected to the first side column or the second side column through a cable; the mooring post assembly includes a mooring post fixed to the bottom of the water. The mooring post is located outside the first side column and the second side column in the first direction and on the side of the leaning surface away from the third side column. The mooring post is detachably connected to the first side column or the second side column or the third side column through a cable; the anchor assembly includes an anchor that can be fixed to the bottom of the water. The anchor is located on the side of the third side column away from the leaning surface, and the anchor is detachably connected to the third side column through a cable.

[0007] In the above solution, by arranging a pile-leaning assembly, a mooring post assembly, and an anchor assembly on the outer periphery of the floating platform, the position limitation of the floating platform from the dock is eliminated, the applicable range of the floating platform is increased, and the floating platform can be made applicable to installing a wind turbine and can also resist typhoons by switching the connection states of the floating platform with the pile-leaning assembly, the mooring post assembly, and the anchor assembly, thus avoiding the high time cost caused by having to avoid the typhoon season when installing the wind turbine.

[0008] In one embodiment, the number of berthing piles is two. The two berthing piles are spaced apart along the first direction and symmetrically arranged relative to the third side column. The berthing pile closer to the first side column is connected to the second side column, and the berthing pile closer to the second side column is connected to the first side column.

[0009] In one embodiment, the number of mooring posts is two. The two mooring posts are spaced apart along the first direction and symmetrically arranged relative to the third side column. The mooring post closer to the first side column is connected to the first side column or the third side column, and the mooring post closer to the second side column is connected to the second side column or the third side column.

[0010] In one embodiment, a mooring pad is provided on the outer periphery of the mooring pile, the mooring pile is located at the connection between the leaning surface and the first side column, the mooring pad is arranged toward the leaning surface and the first side column, and / or the mooring pile is located at the connection between the leaning surface and the second side column, the mooring pad is arranged toward the leaning surface and the second side column.

[0011] In one of the embodiments, the temporary mooring system for installing the floating wind turbine on the floating platform further comprises a mooring mechanism, wherein the mooring mechanism is detachably connected to the third side column, and the mooring mechanism is used to adjust the length of the cable.

[0012] In one embodiment, the number of the anchors is at least two, and the at least two anchors are spaced apart along the first direction and symmetrically arranged relative to the third side column.

[0013] In one embodiment, the second direction is consistent with the direction of water waves, and the waves move in a direction from the leaning surface to the third side column.

[0014] In one of the embodiments, when the temporary mooring system for installing a floating wind turbine on a floating platform is in a wind turbine installation mooring mode, the third side column is connected to the mooring pile assembly, the first side column and the second side column are both connected to the pile support assembly, and the leaning surface abuts against the mooring pile.

[0015] In one embodiment, the temporary mooring system for installing a floating wind turbine on a floating platform further includes an installation vessel, which is located on a side of the mooring pile away from the leaning surface, and is used to install the wind turbine to the first side column and / or the second side column.

[0016] In one of the embodiments, when the temporary mooring system for installing a floating wind turbine on a floating platform is in a typhoon-resistant mooring mode, the third side column is connected to the anchor assembly, the first side column and the second side column are both connected to the mooring pile assembly and the mooring pile assembly, and there is a gap between the leaning surface and the mooring pile.

Then, the first side column 111 is connected to the mooring cable pile 131 and the berthing pile 121, and the second side column 112 is connected to the mooring cable pile 131 and the berthing pile 121.

[0059] When the temporary mooring system 100 for installing a floating wind turbine on a floating platform switches from the wind turbine installation mooring mode to the anti-typhoon mooring mode, it is necessary to disassemble the wind turbine 170 and the like already installed on the floating platform 110, move them to the installation ship 160, and go to a safe haven or the anchor 141 area with the installation ship 160 for typhoon avoidance.

[0060] In the above solution, by providing the berthing pile assembly 120, the cable pile assembly 130 and the anchor assembly 140 on the outer periphery of the floating platform 110, when the temporary mooring system 100 for installing a floating wind turbine on a floating platform is in the wind turbine installation mooring mode, the first side column 111 and the second side column 112 are connected to the berthing pile assembly 120, and the third side column 113 is connected to the cable pile assembly 130, so as to limit the floating platform 110 by the fixed berthing pile 121 and the mooring cable pile. When the temporary mooring system 100 for installing a floating wind turbine on a floating platform is in the anti-typhoon mooring mode, the third side column 113 is connected to the anchor assembly 140, and the first side column 111 and the second side column 112 are both connected to the berthing pile 121 and the mooring cable pile at the same time, thereby improving the limiting strength of the floating platform 110 in the anti-typhoon mooring mode and enabling the floating platform 110 to withstand greater wind forces.

[0061] In the above solution, by arranging the pile-leaning assembly 120, the bollard assembly 130 and the anchor assembly 140 on the outer periphery of the floating platform 110, the position limitation of the floating platform 110 from the dock is removed, the application range of the floating platform 110 is increased, and the floating platform 110 can be made applicable to the installation of the fan 170 and can also resist typhoons by switching the connection states of the floating platform 110 with the pile-leaning assembly 120, the bollard assembly 130 and the anchor assembly 140, thereby avoiding the high time cost caused by the need to avoid the typhoon season when installing the fan 170.
