This vessel is the first CAT-SWATH dual-mode wind power operation and maintenance vessel in China. Besides the advantages of the small waterline area catamaran hull and the application scenarios of dual-mode operating conditions transition, this vessel uses a jet pump as the main propulsion system, coupled with a single-handle vector control system, as well as a bow thrust and a convex point docking design at the bow. These features effectively improve the success rate of docking operations at wind turbines and the efficiency of operation and maintenance, greatly expanding the operation window period.
