A transport and installation ship, and a method for transporting and installing a wind turbine by a ship

Abstract

The invention relates to a transporting and installing vessel and a method for transporting and installing a wind turbine generator set using the transporting and installing vessel. The transporting and installing vessel comprises: a vessel body, a tower support, a guide rail, a movable beam, a balance beam, an upper hanging bracket and hoisting equipment, wherein the vessel body is provided with a lengthways axle wire and a U-shaped opening; the bottom of the tower support is fixed at two sides of the lengthways axle wire on the vessel body, and is in parallel with the lengthways axle wire; the movable beam is arranged above the U-shaped opening, can move along with a guide rail fixed on the tower support, and is respectively connected with the hoisting equipment and the upper hanging bracket; the balance beam is arranged at the upper surface of the movable beam, and is used for locking a tower cylinder of the wind turbine generator set and the wind turbine generator set together; the upper hanging bracket is connected with the bottom of the wind turbine generator set to support the wind turbine generator set; and two sides of the hoisting equipment are respectively fixed on the tower support, and are used for driving the movable beam to move up and down along with the guide rail. According to the technical scheme of the invention, the marine installation efficiency of the wind turbine generator set can be improved, and the vessel is less influenced by sea state.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a transport and installation ship and a method for transporting and installing wind turbines by ship. Background technique [0002] With the rapid development of the wind power industry, the development of onshore wind farms is becoming increasingly saturated. Offshore wind farms, with their advantages of high wind speed, low turbulence, and small wind shear, have become a field of wind power that urgently needs to be developed. In addition, as the single-unit capacity of wind turbines gradually increases, the volume and weight of each component of the unit also increases. For example, the mass of a wind turbine is about 800 tons. Installation to offshore foundations is very difficult. [0003] The existing technology for transporting wind turbines at sea is to use a transport ship to transport the components of the wind turbine, such as the tower, engine room, blades, etc.,...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that using the existing technology to transport wind turbines at sea, since each component is transported separately to the vicinity of the offshore foundation, it is necessary to install the wind turbine in the harsh and changeable offshore environment. The static test and grid-connected commissioning of the whole machine must be carried out in the offshore environment, and because the existing technology requires the close cooperation between the transport ship and another ship equipped with a hanger, or with the offshore floating crane near the offshore foundation, it can be finally completed The installation of wind turbines, therefore, the existing technology results in low efficiency of installing wind turbines at sea, and is seriously affected by sea conditions. When sea conditions permit, it takes about 2-3 days to complete the installation of a wind turbine. Test and debugging takes longer
