Problems solved by technology

[0002] With the development of offshore wind power, the water depth of wind farms is gradually deepening. When the water depth reaches 40 meters or even deeper, the cost of traditional fixed foundations is relatively high, and in deep sea areas, there are fewer ships available, and the requirements for construction equipment are higher. , the construction cost is high, and the floating foundation has obvious advantages. Therefore, reducing the offshore operation process and reducing the project cost are the subjects that need to be studied and solved urgently for the foundation of deep sea floating wind turbines.

Embodiment Construction

[0019] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with the embodiments and accompanying drawings. The embodiments are only used to explain the present invention, and do not constitute a limitation to the protection scope of the present invention.

[0020] An offshore wind turbine Spar-type floating foundation barge transportation assistance process, the Spar-type floating foundation is installed on a special barge, and the special barge is provided with a forepeak tank 6, a ballast tank 5 and a ship engine room in sequence from the bow to the stern 7. A windlass 8 is installed above the fore peak 6, and a steering gear 9 is installed behind the ship’s engine room 7. The special barge 1 equipped with the Spar-type floating foundation is towed by a consignment ship to the wind turbine stand, and then passed to Filling water in the special barge 1 makes one end of the barge 1 sink to realize t...

Abstract

The invention discloses a process for assisting the transportation and installation of a Spar-type floating foundation barge for an offshore fan. The Spar-type floating foundation is installed on a special barge, towed to the position of the fan, and then one end of the barge is sunk by filling water into the barge. Realize the erection and installation of Spar type floating foundation. The advantages of the present invention are: the production of the Spar-type floating foundation and the installation of wind turbines are completed on land, and there are few offshore processes, and no large-scale lifting device is required, and the influence of the weather is small; the project cost is low, and it is a deep-sea floating It provides guidance for the construction of the foundation of the wind turbine and the large-scale construction of the installation of the wind turbine, which has a strong promotion value.

Description

technical field [0001] The invention relates to the field of wind power equipment, in particular to an offshore wind turbine Spar-type floating foundation barge assisting and assembling process. Background technique [0002] With the development of offshore wind power, the water depth of wind farms is gradually deepening. When the water depth reaches 40 meters or even deeper, the cost of traditional fixed foundations is relatively high, and in deep sea areas, there are fewer ships available, and the requirements for construction equipment are higher. , The construction cost is high, and the floating foundation has obvious advantages. Therefore, reducing the offshore operation process and reducing the project cost are the subjects that need to be studied and solved urgently for the deep sea floating wind turbine foundation. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides an offshore wind turbine Spa...
