The invention relates to a ring beam lifting system for an offshore platform, in particular to a ring beam continuous hydraulic cylinder lifting system for the offshore platform. The ring beam continuous hydraulic cylinder lifting system for the offshore platform comprises a ring beam assembly and a hydraulic assembly. The ring beam assembly is provided with an upper ring beam. Upper plug pins are arranged on the inner surface of the upper ring beam and connected with upper plug pin oil cylinders. Lifting oil cylinders are arranged on the bottom surface of the upper ring beam. A lower ring beam is connected to the bottoms of the lifting oil cylinders. Lower plug pins which stretch and retract relative to pin holes in pile legs are further formed in the inner side of the lower ring beam. Lower plug pin oil cylinders are arranged in the lower plug pins. The hydraulic assembly comprises a hydraulic source, lifting oil cylinder hydraulic circuits and plug pin control circuits, wherein the lifting oil cylinder hydraulic circuits are connected with the lifting oil cylinders respectively, and the plug pin control circuits are connected with the upper plug pin oil cylinders and the lower plug pin oil cylinders. According to the ring beam continuous hydraulic cylinder lifting system for the offshore platform, the lifting and locking way of the ring beam lifting system is changed, the problem of poor using stability caused by an original lifting and locking way is solved, and thus a beam replacement system can bear a larger load and can work more stably and reliably.
