The invention provides a mooring hydraulic bearing rotating ring. The mooring hydraulic bearing rotating ring is characterized in that the mooring hydraulic bearing rotating ring comprises a lower ring hole end cover, a cylinder body, a sliding bearing, a thrust bearing and an upper ring eye end cover; a long rotating shaft is arranged on the lower ring eye end cover; the cylinder body, the sliding bearing and the thrust bearing are sequentially arranged on the long rotating shaft; the shaft end is pressed through a pressing piece; the lower ring hole end cover and the cylinder body can rotate relatively; the cylinder body is fixedly connected with the upper ring hole end cover. The mooring hydraulic bearing rotating ring has the advantages that ring holes in the upper ring eye end cover and the lower ring hole end cover are connected with two segments of mooring structural pieces respectively; when the upper mooring structural piece and the lower mooring structural piece bear torsional load, the upper ring hole end cover and the lower ring hole end cover can relatively rotate, and the torsional load is unloaded; the cylinder body is filled with oil, and sealing is conducted through oil seal, a cylinder body sealing ring and an oil injection hole sealing ring; no oil is leaked outside, and no water is leaked inside; it is guaranteed that the bearing is fully lubricated, the difference of the inner pressure and the outer pressure is nearly zero when the mooring hydraulic bearing rotating ring is used underwater, and outer pressure deformation is avoided.
