The tower of an offshore wind turbine is usually about four sections, each section has a length of about 20 meters, a diameter of about 7 meters, and a weight of about 100 tons. The marine transportation of a wind turbine tower is limited by the driving sight distance requirement of a transport ship and the size limitation of a ship, the wind turbine tower is transported in a horizontal lying state in most of the existing transportation modes, and a special saddle needs to be configured on the tower, so that the bearing and binding functions of the tower are realized. After the tower barrel horizontally lies and arrives at a wind field, the tower barrel needs to be turned over through a crane and a special rigging, and when the tower barrel is turned over to be in a vertical state, the tower barrel is hoisted and butted.

The existing horizontal transportation mode of the tower barrel occupies a large area of a deck, and the transportation capacity of a transport ship cannot be fully exerted. After the tower drum is transported to a wind field in a lying state, the tower drum needs to be additionally turned over, so that the operation procedures and the operation time are increased. Based on the reasons, the inventor designs a vertical transportation universal tray, and changes the lying state of the fan tower drum into the standing state for transportation.
