Description

Temporary mooring system for floating type fan mounted on floating platform

Technical Field

The application relates to the technical field of offshore wind power and ocean engineering, in particular to a temporary mooring system for a floating type fan mounted on a floating platform.

Background

At present, offshore wind power generation is mainly based on a fixed wind turbine platform (or called a wind turbine foundation), but the sea area suitable for the fixed wind turbine platform is limited. The open sea wind power construction is transferred from a shallow water range with the water depth of 30m to 50m to an open sea water area with the water depth of more than 50m, the fixed foundation becomes uneconomical due to the increase of the water depth, and a floating platform which is insensitive to the increased water depth and even more adaptive becomes a foundation form with important prospect.

At present, various floating fan platforms built in the world are moored beside a dock to carry out installation operation of floating fans. The floating fan platform moors to the wharf side to install the floating fan, and the first problem is that the wharf suitable for installing the large floating fan is more and more scarce. The wharf suitable for installing the large floating fan needs to have the following conditions: 1) The large crawler crane or the circular track crane needs to be positioned beside a wharf to form a fixed hoisting foundation, and the front edge of the wharf is a wharf foundation with high bearing capacity; 2) The floating type fan platform needs to be berthed at a wharf, and the water depth at the front edge of the wharf meets the design requirement of the fan platform and generally needs to exceed 10m; 3) The wharf can not be too far away from the offshore floating type fan mounting machine, so that the long-distance integrated towing operation of the platform and the fan is avoided; 4) When the floating type fan is installed, the requirement on the movement of a basic platform is extremely high, and a long-time surge-free installation window is needed beside a wharf. Wharves having the above conditions are not only extremely expensive to build, but also have become more scarce for hire.

In the field of floating fan installation, one problem that is faced at present is how to prevent typhoons or other severe weather at the fan installation stage. The problem is not serious for one or a small number of prototype projects, the fan installation can be avoided in typhoon seasons, but for the whole wind field (a plurality of fans need to be installed), the whole typhoon season or all bad weather is difficult to avoid due to the long installation period.

When the temporary mooring system 100 for the floating fan installation on the floating platform is switched from the fan installation mooring mode to the anti-typhoon mooring mode, it is necessary to detach the fan 170 or the like already installed on the floating platform 110, move it to the installation vessel 160, and perform platform avoidance with the installation vessel 160 to the wind sheltering port or anchor 141.

In the above solution, by providing the pile assembly 120, the bollard assembly 130 and the anchor assembly 140 at the periphery of the floating platform 110, when the temporary mooring system 100 for installing the floating wind turbine on the floating platform is in the wind turbine installation mooring mode, the first side upright 111 and the second side upright 112 are connected to the pile assembly 120, and the third side upright 113 is connected to the bollard assembly 130, so as to limit the floating platform 110 by the fixedly provided berthing pile 121 and the mooring pile, and when the temporary mooring system 100 for installing the floating wind turbine on the floating platform is in the anti-typhoon mooring mode, the third side upright 113 is connected to the anchor assembly 140, and both the first side upright 111 and the second side upright 112 are connected to the berthing pile 121 and the mooring pile at the same time, so that the limiting strength to the floating platform 110 in the anti-typhoon mooring mode is improved, and the floating platform 110 can bear higher wind force.

In the above solution, the pile leaning assembly 120, the cable pile assembly 130, and the anchor assembly 140 are disposed on the periphery of the floating platform 110, so that the position of the floating platform 110 departing from the dock is limited, the application range of the floating platform 110 is increased, and the floating platform 110 can be adapted to the installation of the fan 170 and can resist typhoon by switching the connection state of the floating platform 110 with the pile leaning assembly 120, the cable pile assembly 130, and the anchor assembly 140, thereby avoiding high time cost caused by avoiding typhoon seasons when the fan 170 is installed.
