Description

Technical Field

[0001] This invention relates to a method for installing wind turbine jacket blades in a single row, belonging to the technical field of offshore wind turbine blade installation. Background Technology

[0002] With the continuous development of offshore wind power, the efficiency of offshore wind power construction sometimes determines the construction cost. Construction costs sometimes lie in the transportation of wind turbine components, such as turbine blades, which need to be transported by ship to the wind turbine installation area (see Chinese Patent Publication No. CN117846884A). When the sea winds and waves in the offshore construction environment increase, the ships transporting the blades need to return to port to avoid damage to the turbine blades.

[0003] At wind turbine installation sites far from the coast, ships often have to return to transport the blades, which reduces the efficiency of wind turbine installation and increases the cost of round-trip shipping. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a method for installing wind turbine jacket blades in a single row.

[0005] The present invention is achieved through the following technical solutions.

[0006] The present invention provides a method for installing wind turbine blades on a single-row duct frame, comprising: transporting wind turbine blades to the vicinity of the wind turbine duct frame and placing them independently on the wind turbine duct frame in a single row at intervals, and then hoisting and transferring them to the nearest hub for splicing during the installation process.

[0007] The installation process includes the following steps: tooling interfaces are fixedly installed on the pre-reserved wind turbine tower flange interface on the wind turbine jacket, and tooling interfaces are also fixedly installed on the wind turbine jacket platform. There are six tooling interfaces on both the blade transport vessel and the wind turbine jacket, arranged in pairs.

[0008] The blade transport vessel uses blade support fixtures to stably support the wind turbine blades and transport them to the sea area where the wind turbine is installed.

[0009] The installation process also includes the following steps: when it is anticipated that there will be strong winds and waves, the wind turbine blades will not be detached from the blade support fixtures. The wind turbine blades will be transferred to the adjacent wind turbine jacket frame by a crane on the blade transport vessel. The blade support fixtures and the fixtures interface will be fixed by connecting and fixing through flanges, so that the three wind turbine blades are in a single row on the wind turbine jacket frame. The blade transport vessel will then move away from the wind turbine jacket frame and moor in the nearby sea area.

[0010] The installation process also includes the following steps: when the sea surface meets the construction conditions, the lifting deck platform is located near the wind turbine jacket to be constructed. The wind turbine hub is installed on the lifting deck platform. After the wind turbine hub is installed, the blade transport vessel moored in the nearby sea area transfers the wind turbine blades from the wind turbine jacket to the vicinity of the lifting deck platform. The blade transport vessel also has tooling interfaces. At this time, the blade support tooling and the tooling interface are fixed by connecting and fixing through flanges.

[0011] The installation process also includes the following steps: the wind turbine blades are detached from the blade support fixtures on the blade transport vessel, and the wind turbine blades are connected and installed to the wind turbine hub by a crane on the lifting deck platform. The wind turbine hub with three wind turbine blades is then hoisted to the top of the wind turbine tower for connection and installation.

[0012] The beneficial effects of this invention are as follows: the three wind turbine blades can be placed in a single row on the wind turbine jacket, and the wind turbine jacket provides stable placement for the wind turbine blades in the environment of ocean wind and waves, avoiding the need for the blade transport ship to return to port with the wind turbine blades when encountering ocean wind and waves, ensuring that the components arrive on time during wind turbine construction, improving wind turbine installation efficiency, and reducing the cost of ship round trips.

[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0019] like Figures 1 to 4 As shown.

[0020] The present application discloses a method for installing wind turbine jacket blades in a single row, comprising the following steps.

[0021] The blade transport vessel 1 uses blade support fixture 11 to stably support and transport the wind turbine blade 2 to the wind turbine installation area. The wind turbine jacket 3 has a pre-installed wind turbine tower flange interface 4 with a fixture interface 41. The wind turbine jacket 3 platform also has a fixture interface 41 fixedly installed. There are six fixture interfaces 41 on both the blade transport vessel 1 and the wind turbine jacket 3, arranged in pairs.

[0022] When strong winds and waves are anticipated, the wind turbine blades 2 will not detach from the blade support fixture 11. The wind turbine blades 2 will be transferred to the adjacent wind turbine jacket 3 by the crane on the blade transport vessel 1. The blade support fixture 11 and the fixture interface 41 will be fixed by flange connection, so that the three wind turbine blades 2 are in a single row on the wind turbine jacket 3. The blade transport vessel 1 will then move the wind turbine jacket 3 to a nearby sea area for mooring.

[0023] When the sea surface meets the construction conditions, the lifting deck platform 5 is located near the wind turbine jacket 3 to be constructed. The wind turbine hub 6 is installed on the lifting deck platform 5. After the wind turbine hub 6 is installed, the blade transport vessel 1, which is moored in the nearby sea area, transfers the wind turbine blades 2 from the wind turbine jacket 3 to the vicinity of the lifting deck platform 5. The blade transport vessel 1 also has a tooling interface 41. At this time, the blade support tooling 11 is fixed to the tooling interface 41 by connecting and fixing through the flange.

[0024] Then, the wind turbine blades 2 are detached from the blade support fixtures 11 on the blade transport vessel 1. The wind turbine blades 2 are then connected to the wind turbine hub 6 by the crane on the lifting deck platform 5. The wind turbine hub 6, which has three wind turbine blades 2 installed, is then hoisted to the top of the wind turbine tower 7 for connection and installation.

[0025] The three wind turbine blades 2 can be placed in a single row on the wind turbine jacket 3. The wind turbine jacket 3 provides stable placement for the wind turbine blades 2 in the environment of high wind and waves, avoiding the need for the blade transport vessel 1 to return to port with the wind turbine blades 2 when encountering high wind and waves. This ensures that the components arrive on time during wind turbine construction, improves wind turbine installation efficiency, and reduces the cost of round-trip shipping.

[0026] This application enables the wind turbine blades 2 to be transported to the wind turbine jacket 3 and then hoisted and transferred to be spliced ​​with the nearest hub 7.
