Abstract: The present disclosure provides an annular anchor installing instrument and an annular anchor installing method, relating to the technical field of ocean engineering. The annular anchor installing instrument includes an installation tube, a pump body assembly, a lifting portion and an installation portion. One end of the installation tube is provided with a cover body, and the other end of the installation tube is configured to be an open end for cooperating with the top of the annular anchor. The pump body assembly is arranged on the cover body, and used to vacuum the interior of the installation tube. The lifting portion is arranged on the cover body, and used to connect with a hoist. The installation portions are removably arranged on the cover body, and used to connect with the hoist and the anchor chain of the annular anchor, respectively.

Abstract: The present invention discloses a large-scale model testing system of a floating offshore wind power generation device, and a method for manufacturing the large-scale model testing system. The large-scale model testing system comprises a floating wind power generation device model, model response measurement systems and environmental parameter measurement systems. The floating wind power generation device model comprises a floating foundation and a tower, wherein a wind turbine is connected to the top of the tower. A plurality of anchoring devices is connected to the side surface of the floating foundation. Each model response measurement system comprises an IMU unit, a wind turbine monitoring unit and an anchoring tension measurement unit. Each environmental parameter measurement system comprises a buoy-type wave height meter, a wind speed and direction meter and a flow velocity and direction meter.
