Recently, Wuhan Marine Machinery Co., Ltd. developed the core equipment for the 300-foot self-elevating offshore drilling platform. China’s first set of electric rack and pinion lifting system and locking device with independent intellectual property rights passed the acceptance of the Ministry of Science and Technology, marking the Wuhan ship. The company's research and development capabilities in the field of offshore platform lifting systems have reached a new level.
The electric rack and pinion lifting system developed by the company is driven by a variable frequency motor, and the locking device adopts a hydraulic drive locking method to complete the transmission of force between the platform and the legs. The topic comes from the National High-Tech Research and Development Program ( 863 Program). Since the establishment of the project, the company has attached great importance to it, gradually overcome various technical difficulties, formed an intelligent motion control strategy, completed the development of the joint test bed, and owned A set of design schemes and joint test verification methods for electric rack and pinion lifting systems and locking devices with independent intellectual property rights.
Since the domestic jack-up drilling platform lifting system and locking device are basically dependent on imports, the project has been successfully developed, breaking through the technical blockade of the product abroad, breaking the long-term monopoly of foreign suppliers in this field and improving the ocean. The independent supporting ability of engineering equipment design.
