Description
Technical Field
[0001] The present invention relates to the technical field of wind power platform towing, in particular to a method for monitoring and controlling the towing motion state of a semi-submersible wind power platform. Background Art
[0002] In recent years, my country's offshore wind power has developed rapidly, with offshore wind power installations gradually reaching saturation, and the offshore wind power industry gradually expanding into the deep sea. Semi-submersible wind turbine platforms, as a key structural form of deep-sea wind power, have enormous development potential. Offshore semi-submersible steel wind turbine platforms are generally manufactured and assembled in land-based shipyards or steel structure manufacturing plants. They are then transported to the target sea area for installation using dry or wet towing methods. The wind turbine platform construction plant is generally far from the installation site, necessitating the use of safe and economical transportation methods to ensure the safe transfer of the wind turbine platform. Semi-submersible wind turbine platforms are relatively large, making wet towing a more economical and reasonable method of transport.
[0003] The attitude of a semi-submersible wind turbine platform during towing is a significant factor affecting towing safety and flotation stability. The platform's motion during towing includes structural inclination and speed. Currently, the method for determining the platform's inclination during towing is generally to visually observe the draft markings at various locations on the platform structure to calculate the platform's inclination. The platform's operating speed is generally determined by the tugboat's speed as the towed object's speed. Visual readings are affected by the operator's skill level, and flexible cables are typically used between the tugboat and the wind turbine platform for towing. Therefore, visually observing the draft markings and judging the platform's motion based on the tugboat's speed are both inaccurate and inefficient. Furthermore, there are currently no effective measures for adjusting the flotation of a towed object during towing. Therefore, a new method for monitoring and controlling the wind turbine platform's motion during towing is needed to address these technical issues. Summary of the Invention

It should be noted that during the towing operation, the first tugboat 2 is responsible for towing the wind turbine platform forward, while the second tugboat 3 and the third tugboat 4 are responsible for adjusting the floating state of the wind turbine platform. It should be noted that before the towing operation of the semi-submersible wind turbine platform 1, three sets of towing motion state monitoring modules 8 are installed on the three column decks of the semi-submersible wind turbine platform 1 according to the detection module layout installation diagram, and the inclinometer, GPS positioner, and other equipment are calibrated. By comparing the three sets of monitoring data, the accuracy of the monitoring data can be further improved.

[0042] It should be noted that when the semi-submersible wind power platform 1 is towing, the anemometer 81, GPS locator 82, and inclinometer 83 transmit the wind speed, position, speed, tilt angle and other motion status information of the monitored semi-submersible wind power platform 1 to the information collector 86. The information collector 86 transmits the motion status information of the semi-submersible wind power platform 1 to the wireless information receiving, analyzing and processing terminal on the towing command ship 9 in real time through the wireless signal transmitter 84. The wireless information receiving, analyzing and processing terminal analyzes the data in a timely manner and responds to it.
[0043] Specifically, in this embodiment, exhaust fans 871 and ventilation holes 872 are provided on both side walls of the protective housing 87. It should be noted that the exhaust fans 871 and ventilation holes 872 are provided to dissipate heat, thereby ensuring that the temperature inside the protective housing 87 is maintained within a certain range, allowing the battery 85 and the information collector 86 to function normally.
