Abstract

According to the construction device and the operation method for installing the fan component in the floating state on the offshore crane ship, a bottom-section tower drum of a fan is hoisted to a vertical transportation tool on a deck of a transport ship from a wharf, and a middle-lower-section tower drum and a middle-upper-section tower drum of the fan are assembled on the wharf and then hoisted to the vertical transportation tool on the deck of the transport ship. And the vertical transportation tool is used for assembling a top section tower drum, a cabin, a generator and a hub of the fan and hoisting the assembled top section tower drum, the cabin, the generator and the hub to a deck of a transportation ship. After the transport ship transports fan components to a construction site, the crane ship completes installation work of a fan bottom section tower drum, a middle lower section-middle upper section tower drum assembly and a top section tower drum-generator-cabin-hub assembly in sequence in a floating state. A fan cabin, a generator and a hub can be installed on the crane ship in a floating state, and the situation that resources of a fan installation platform ship are insufficient is relieved to a certain degree. Partial assembling work of the fan unit is completed at a wharf, the operation time of offshore fan installation can be shortened, and the use efficiency of a ship machine is improved.

Description

technical field [0001] The invention relates to the field of installation of offshore wind turbines, in particular to a construction device and an operation method for installing wind turbine components in a floating state on an offshore crane ship. Background technique [0002] In the rush to install wind power at sea, the resources of wind turbine installation platforms and ships are tight, and the floating installation of wind turbine towers, engine rooms, generators, and hubs by crane ships can effectively alleviate the shortage of wind turbine installation platform and ship resources, improve the efficiency of wind turbine installation, and speed up project construction schedule. When the crane ship is in a floating state, the hook head shakes to a certain extent due to the swell, and it is difficult to align the wind turbine generator, engine room, and hub bolts at high altitude, which is difficult to install and has high safety risks. Therefore, it is necessary to op...
