The bilge intake seawater ballast system mainly comprises a subsea valve box, a ballast water pump, valves, ballast water pipelines, air pipelines, ballast water tanks and the like, wherein the subsea valve box of the system is arranged at the bottom of a floating foundation, and the ballast water pump takes water from the subsea valve box and conveys the water to each ballast water tank to load a floating platform. And the seawater in the ballast water tank is discharged through a tank bottom water outlet by utilizing a ballast water pump in cooperation with the opening and closing of the pipeline and the valve, so that the load discharge of the floating platform is realized. The main disadvantages of this system include: (1) the subsea valve box and the drain port have problems with plugging by marine organisms. Although the floating type wind power equipment is designed to adopt a permanent ballast system, after the equipment is installed in place and ballasted, the floating type offshore wind power equipment does not carry out loading and discharging work during operation, according to the standard requirement, the ballast water tank needs to be overhauled every 5 years, so that the discharging and loading work is required. (2) The water inlet valve is damaged and difficult to maintain. The water inlet valve connected with the seabed valve box has the risks of corrosion damage, seal ring aging and the like in the 25-year life cycle of the floating wind power equipment, once the water inlet valve is damaged, bilge water enters, the work of on-site maintenance and valve replacement is difficult, if the floating wind power equipment cannot be maintained on site, the floating wind power equipment can only be maintained in a dock, and the maintenance cost is high.
Outboard intake seawater ballast system. The outboard water intake and discharge ballast system respectively adopts two sets of independent systems, the loading system comprises a submersible pump, a ballast water pipeline, an air pipeline, a valve, a ballast water tank and the like, and when the floating type wind power equipment carries out seawater loading, water is taken from the outboard through the submersible pump and goes over the floating type foundation deck to carry out seawater loading to the ballast water tank in the floating type foundation. The ballast discharging system also comprises a submersible pump, a ballast water pipeline, a valve and the like, wherein the submersible pump is arranged in the ballast water tank at the lowest part of the floating foundation. The main disadvantages of this system include: (1) because two sets of seawater loading and discharging systems are adopted, the pipeline system is complex, and therefore the design and manufacturing cost of the system is relatively high. (2) And the submersible pump in the ballast tank is difficult to maintain.
Therefore, a floating type seawater ballast system for wind power equipment is needed, which can meet the requirements of seawater loading and discharging, avoid the difficulties of maintenance and operation, and reduce the design and manufacturing cost.
