CSSC Chengxi delivers the first domestic 5 MW offshore wind tower

Recently, CSSC Chengxi Ship Repair Co., Ltd. successfully delivered the first 5 MW offshore wind tower in China. This is the company's initiative to adjust the product structure, optimize resource allocation, adhere to the connotation development, and use existing shipbuilding resources to expand non-ship business. A breakthrough in innovation.

Actively adjust shipbuilding capabilities and expand non-ship operations. At present, the ship market continues to be turbulent in the trough, shipbuilding orders are drastically reduced, shipbuilding profits will be very difficult, and production resources are highly likely to be short-lived. In the face of severe market conditions, the company actively optimizes resource allocation and actively adjusts shipbuilding capabilities. It aims to maintain a certain shipbuilding scale and quickly convert some shipbuilding resources to non-ship production by improving shipbuilding management level and production efficiency. Maintain the stability of the economic aggregate in the market against the trend. A few years ago, the company determined its goal of entering the offshore wind tower market. In March 2010, it obtained the steel structure welding quality certification issued by the German SLV, and obtained the tickets directly into the international market, especially in the European market. In 2011, through the application to establish a special project for offshore wind towers, the company obtained national R&D funds, which laid a solid foundation for the company to enter the offshore wind power tower market.

It is reported that the 5 MW offshore wind tower of Chongqing Haizhuang Wind Power Equipment Co., Ltd. delivered by this time consists of three parts, of which 6 steel pipe piles weigh about 325 tons; the six pile jacket base weighs about 500 tons; About 350 tons, the total weight of the whole set of equipment is about 1200 tons.

Adhere to the development of connotation and strive to seize market opportunities. The construction of an offshore wind tower requires a complete production line and large lifting equipment, and the construction of such a production line requires less than one year. It takes time and does not require a considerable investment. The company adheres to the connotation development, and puts the production of the offshore wind tower on the ring-shaped assembly site of the shipbuilding line 4, so that the site can not only complete the new ship manufacturing, but also form the offshore wind tower manufacturing line. On this production line, 7 sets of offshore wind towers can be started at the same time. The company has formed the capacity to build more than 50 sets of offshore wind towers without investment, creating conditions for large-scale undertaking and manufacturing of offshore wind towers. It is of great significance for the company to seize the opportunity of the offshore wind tower market, to make the sea wind tower market and achieve sustainable development.

Use shipbuilding technology to help non-ship development. The company has successfully built four 35,500-ton self-unloading vessels, two 35,000-ton bulk carriers and five 30,000-ton bulk carriers in the country's first flat-bottom shipbuilding and floating docking technology . This time, the company has combined the mature flat shipbuilding technology with the offshore wind tower manufacturing to achieve a major breakthrough in the manufacture of offshore wind towers. It took only two months to complete the construction of the entire offshore wind tower, which took 45 days. The final assembly task was completed in less than a month, and the construction quality and construction speed were the highest in China. The company's high efficiency and high quality have made the on-site supervisors express their heartfelt feelings: I am working in Chengchuan Chengxi rather than working as a vacation.

At present, the offshore wind tower has been shipped to the Rudong area of ​​Jiangsu Province. A tall and straight wind tower will soon stand in the largest offshore wind farm in Asia, contributing to the local economic construction.
