The south China sea has abundant wind power resources, but the sea condition is complex, and the integrated installation of the fan and the floating foundation is generally finished on the shore and then the wind power generator is towed to a set site for power generation. In order to ensure the towing safety, a certain towing draft is generally ensured by solid ballast, and then the towing draft is carried out after the towing draft is towed to a platform site for water injection and loading, so that the draft meeting the operation requirement is achieved.
As an unattended platform, the ballast tank is generally designed according to a permanent ballast tank, namely after one-time ballasting is finished, subsequent load regulation is not needed. In addition, by reasonably designing an overhaul channel in a high stress area and considering reasonable ballast tank anticorrosion measures, the ballast tank can be drained for special inspection and exemption; only under special operating conditions, such as cabin breaking and towing and docking, drainage is needed, so that the times of pressure drainage adjustment in the whole life cycle are few. The existing pressure and exhaust system of the mobile platform or the floating production device comprises a liquid level remote measurement system, a hydraulic submerged pump and a valve remote control system, and has the disadvantages of complex configuration, high cost and high later maintenance cost, so the pressure and exhaust system of the conventional floating platform cannot be suitable for the requirement of a wind power platform.
