To achieve this goal, there is a strong drive to use renewable energy to improve the carbon dioxide emissions into the atmosphere from the burning of fossil fuels. Onshore and offshore wind power emits on average 11g/kWh carbon dioxide over the full life cycle and is expected to fall further into the range of 6-7g/kWh, in contrast to 27g/kWh for photothermal, 44g/kWh for photovoltaic, 450g/kWh for natural gas, 1000g/kWh for coal, and only 9g/kWh for nuclear power roughly comparable to wind power. For upgrading of energy structures, wind power is a necessary way for China to go. Offshore wind power has the following advantages over onshore wind power: the influence on the climate is small; the offshore wind resources are superior; saving land, etc.
Common foundations for offshore wind power are as follows: gravity type foundation, single pile foundation, suction type foundation, composite type foundation and the like. The suction type foundation has the advantages of being simple to manufacture, convenient to install, short in construction period and the like, and has a good application prospect. The suction anchor is mainly used for anchoring offshore wind power or an ocean platform in a deep water area, negative pressure can be generated through suction, and the suction anchor sinks into the sea bottom under the action of the negative pressure and self weight. The uplift bearing capacity of the traditional suction anchor mainly depends on the friction force between the cylinder wall and ocean soil, the sinking penetration mainly depends on the action of negative pressure and dead weight, but the sinking penetration effect is poor, the uplift capacity is also poor, and therefore a technical scheme capable of solving the problem is urgently needed.
