OVERALL HORIZONTAL PRELOADING-BOARDING SYSTEM FOR OFFSHORE WIND TURBINE AND PRELOADING-BOARDING METHOD

摘要

The invention relates to an integrated horizontal preassembling and loading-out system and method for offshore wind turbines. The system comprises: self-propelled modular transporters disposed at a dock, a wind turbine installation vessel and lifting devices, wherein the transporters comprise tower transporters and a nacelle transporter; the tower transporters comprise lower tower transporters, a middle tower transporter and an upper tower transporter; a lower tower, a middle tower, an upper tower and a nacelle of a wind turbine are correspondingly mounted on the three types of transporters; the lower tower transporters, the middle tower transporter, the upper tower transporter and the nacelle transporter move along the same axis to implement butting between sections of the wind turbine; the lifting devices comprise supporting legs vertically mounted on the deck, the supporting legs are axially provided with first rails, the first rails are provided with sliding wind turbine lifters, and the wind turbine lifters are provided with fixing clamps. The system uses the self-propelled modular transporters at the dock to implement butting of sections of a wind turbine and integrated preassembling and loading-out, so that the difficulty and risk associated with the preassembling and loading-out of wind turbines are reduced, the efficiency of preassembling and loading-out can be improved, and the energy consumption can be lowered.
