Submerged Floating Tunnel is a large-scale cross-sea traffic structure with good application prospects, mainly composed of tunnel pipe body and buoys. The buoys of the floating tunnel are usually connected to the pipe body through mooring ropes or truss structures to provide buoyancy for the pipe body, so that the tunnel pipe body is suspended in the water. Compared with traditional cross-sea traffic building forms, floating tunnels have significant advantages: (1) The construction of each component can be prefabricated, and the construction site has little impact on the environment and less pollution; (2) It is less affected by harsh natural environments such as dense fog and storms; (3) The impact on the passage of ships on the sea is small; (4) The construction cost does not increase significantly with the increase of the length.

As a supplement to marine fishing, mariculture has developed rapidly in recent years. Marine aquaculture relies on aquaculture boats or large-scale floating aquaculture platforms, supporting cage facilities, industrialized green aquaculture, and a comprehensive fishery production system that integrates digital management. It is a new model of fishery production. Mariculture requires a certain amount of coastal and nearshore space. However, as my country enters a period of large-scale development and utilization of the ocean, the intensity of coastal development has increased, the demand for sea use has continued to increase, and the problem of sea congestion has gradually emerged. Therefore, in the construction of marine structures and the development of marine resources in the future, we should pay attention to integrated development and maximize the benefits of sea area resources.
