On the 26th, the reporter learned from the acceptance and acceptance of the major project "Research and Application of Active Winding Compensation and Sea Winch for Electric Drive" organized by Hunan Science and Technology Department. China has independently developed the first electric driven active heave compensation marine winch with a capacity of 4000 meters. The overall technical level of the international advanced level. Is expected to break the monopoly of foreign countries to promote national marine scientific research and resource development.
In 2014, Hunan set up a major project to take Hunan University of Science and Technology, with its high-end marine equipment research and development technology as its lead unit, aiming at the gaps in domestic high-end marine winch products and to develop and develop an electric-driven deep-sea marine winch with active heave compensation. At present, The project has broken through the two key technologies of the complex design of the marine electro-hydraulic winch complex electro-hydraulic system and the active heave compensation control of the marine winch.The new type of marine winch developed by AC frequency conversion electric drive with active heave compensation and automatic cable laying functions, winch Capacity rope 4500 meters, the maximum speed of 100 m / min, the initiative heave compensation capacity of 0-2.5 m, applicable to the working sea level below 4. Up to now, has won five national invention patents.
'Electric drive active heave compensation offshore winch, has a broad market space and development prospects.If the project results are to promote, is expected to promote the domestic marine winch product structure adjustment and enhance the core competitiveness of China's offshore equipment business.' Hunan Science and Technology University party secretary, project chief expert Liu Deshun said.
