Tension leg floating wind turbines, with their superior mobility, stability, and minimal environmental impact, offer advantages for deep-sea wind power development. However, traditional installation methods for tension leg oil and gas platforms are challenging. These methods involve expensive ribs and connectors, reliance on crane vessels for rib installation, and the need for temporary pontoons. Furthermore, they carry significant installation risks, are highly dependent on vessel and marine environmental conditions, require high precision, and are extremely costly. This makes them unsuitable for large-scale installation of tension leg floating wind turbines, hindering their widespread adoption and application. Utility Model Content

[0026] The suction anchor is installed on the seabed. The installation of the suction anchor is set according to the installation point of the tension leg floating blower b. The fixed end of the suction anchor chain is connected to the suction anchor. The bottom of the tension leg floating blower b is equipped with a float a, which has 3 buoyancy arms.

[0027] There are six temporary locking devices 5. Each temporary locking device 5 is connected in pairs to one of the three buoyancy arms, with the two temporary locking devices 5 belonging to the same pair located on either side of the top of the free end of the buoyancy arm. Each temporary locking device 5 includes a sleeve 501 and a first hydraulic mechanism 502. The sleeve 501 is installed on the top of the free end of the buoyancy arm, and its top end is flared outwards to facilitate the insertion of the truss 1. The first hydraulic mechanism 502 is located on opposite sides of the sleeve 501. The first hydraulic mechanism 502 includes a first hydraulic source and a first hydraulic cylinder connected to the first hydraulic source. The first hydraulic cylinder extends into the sleeve 501, driven by the first hydraulic source, to limit the movement of the truss 1.

[0028] Truss 1 includes column trusses 101, upper chord trusses 102, and lower chord trusses 103. There are 6 column trusses 101. The bottom end of each column truss 101 passes through a sleeve 501 and is detachably connected to the sleeve 501 by first hydraulic cylinders on both sides of the sleeve 501. The upper chord trusses 102 and lower chord trusses 103 are installed in parallel between two column trusses 101 belonging to the same group. There are 3 installation positions between two column trusses 101 not belonging to the same group. The upper chord trusses 102 and lower chord trusses 103 are installed in parallel in 2 of the installation positions, and the remaining installation position is used as a passage for installation work.

[0029] The buoyancy aid 2 is installed between the upper chord truss 102 and the lower chord truss 103.

[0030] There are 6 anchor winches 3, which are installed at the top of each column truss 101. The anchor winches 3 are connected to the fixed end of the anchor chain 4, and the free end of the anchor chain 4 can be connected to the free end of the suction anchor chain through the anchor chain main locking device 6.

[0031] There are six anchor chain main locking devices 6, located below each column truss 101 and fixed to the outer side of the buoyancy arm. The anchor chain main locking device 6 includes a U-shaped fastener 601, a flat fastener 602, a second hydraulic mechanism 603, and a fixing pin 604. The closed end of the U-shaped fastener 601 is fixed to the outer side of the buoyancy arm.

A through hole 605 is provided in the middle of the basic fastener for the anchor chain 4 and the suction anchor chain to pass through. The second hydraulic mechanism 603 is installed on the top of the U-shaped fastener 601. The second hydraulic mechanism 603 includes a second hydraulic source and a second hydraulic cylinder connected to the second hydraulic source. The fixing pin 604 is vertically connected to the second hydraulic cylinder.

The first hydraulic mechanism 502 of the temporary locking device 5 is driven to fix the truss 1 to float a. Alternatively, after the tension leg floating wind turbine b is towed to the installation site, the corresponding truss 1, buoyancy aid 2, anchor winch 3, anchor chain 4, temporary locking device 5, and anchor chain main locking device 6 can be installed using a floating crane.

[0033] 2) After the tension leg floating wind turbine b reaches the installation point, the free end of the anchor chain 4 is connected to the free end of the suction anchor chain at the seabed, and the float a is filled with ballast water. If necessary, the buoyancy aid device 2 is used to assist in injecting ballast water so that the float a sinks to the design draft depth, which is >25m.

[0034] 3) Start the anchor winch 3 to make the anchor chain 4 and the suction anchor chain vertical but not tensioned. Then the float a and the buoyancy aid 2 discharge ballast water, making the anchor chain 4 and the suction anchor chain tensioned. The anchor chain main locking device 6 fixed on the tension leg floating blower b is activated. With the help of the second hydraulic cylinder, the fixing pin is inserted and locked to the anchor chain 4 and the suction anchor chain.

[0035] 4) Remove the anchor chain 4 from the anchor chain main locking device 6 on the side closest to the water surface, so that the first hydraulic mechanism 502 of the temporary locking device 5 can be released, and the truss 1, buoyancy aid 2, anchor winch 3 and anchor chain 4 can be separated from the float a.

[0036] 5) Using the buoyancy aid 2, tow the truss 1, buoyancy aid 2, anchor winch 3 and anchor chain 4 to the dock and install them on the next floating wind turbine. Repeat step 1) to start the installation of the next tension leg floating wind turbine b.
