Technical Field

Background
Offshore wind energy plays an important role in reducing greenhouse gas emissions and meeting growing energy demands, and is therefore widely accepted. By the end of 2020, the global offshore wind power accumulated installed capacity is 32.5GW, and the global commissioned offshore wind farms are 162 in total. At present, most offshore wind turbines in the world are of a bottom fixed structure. With the continuous saturation of wind power development in shallow sea areas, the offshore wind power industry begins to develop to the deep open sea in recent years. However, as water depth increases, the difficulty and cost of constructing a fixed-foundation offshore wind turbine increases rapidly. For economic reasons, floating wind turbine generators are becoming the focus of research as the water depth increases. At present, the floating offshore wind turbine foundation mainly comprises a spar type foundation, a semi-submersible type foundation, a tension leg type foundation, a barge type foundation and the like, wherein the barge type foundation can be designed into a square or annular floating platform, and a water pool called a moon pool is arranged in the center of the barge type foundation, so that wave load is absorbed, and the motion of a floating body is reduced. The barge type foundation has the advantages of simple structure, low manufacturing cost, long service life, large waterline area, relatively poor hydrodynamic performance, poor wave resistance and large motion response of the platform under the action of waves.
However, the early investment of wind power generation is higher, and the annual income of only one item of power generation is still far lower than the total investment of an offshore wind farm. However, for fish farming, the profit is much higher than that of offshore power generation, and thus wind power generation and offshore farming systems are combined in order to reduce investment pressure. At present, mariculture is mainly focused on offshore, but the offshore culture space is limited, and deep sea cage culture industry for vigorously developing high-economic-value fishes becomes a main development direction of the future of mariculture. However, the deep sea cage culture area has the problems of long offshore distance, severe marine environmental conditions, difficult power supply, high anchoring cost and the like.
