Various types of offshore aquaculture platforms have been developed in the market. In the prior art, for example, patent CN217850849U discloses an offshore aquaculture cage platform that can be easily displaced, including a device body, one end of the device body is connected to a column, the bottom end of the column is bolted to a catamaran buoy, a protective net is fixedly sleeved on the surface of the catamaran buoy, and a rubber membrane is provided on the surface of the protective net. The surface of the catamaran buoy is protected by the protective net and the rubber membrane, and the catamaran buoy is effectively prevented from being severely worn when being dragged and moved on the ground.
