At 3:01 p.m. on March 18, in the sea area of Hangzhou Bay, about 21 kilometers away from Dushan Port, Pinghu City, Jiaxing City, Zhejiang Province, with the final "rumbling" sound coming from the hydraulic hammer of the "Sanhang pile No. 18" pile driving boat, a 101 meter long steel sea superiority machine bearing platform and bottom pile is like a "sea god needle", which is driven into the sea bottom 70 meters away from the sea level after thousands of hammers.
Like a raging fire in the novel coronavirus pneumonia power station, Jiaxing 1, Zhejiang Province, the construction workers are trying to recover the delay of the new crown pneumonia epidemic. By the end of next year, 75 wind turbines of up to 100 meters will be set up in this sea area, delivering 740 million kilowatt hours of clean electric energy for the whole province every year.
At the offshore construction site, Shi Xiaohua, general manager of Zhejiang energy Jiaxing haiyouli power generation company, told reporters that our wind farm covers a total sea area of about 48 square kilometers, with a planned installed capacity of 300 megawatts. It is planned to install 75 sets of 4-megawatt marine advantageous motor units, with a total dynamic investment of about 5.5 billion yuan.
"It is much more difficult to build sea power than to build on land. According to the geological conditions of different stands, there are two types of fan base: high pile cap and single pile base. For the foundation type of high pile and high bearing platform, 8 steel pipe piles are required for each machine position, each of which has a weight of 100 tons, while the steel pipe pile of single pile foundation type has a weight of 850 tons. There are 333 such "seakeeping needles" in the whole wind farm, which can enter the next process of wind turbine installation only after each of them is completed. " Ge Xiaochun, director of the company's engineering department, said that offshore piling is as important as building foundation. Whether the wind turbine can stand the test at any time at sea depends on the stability of the foundation.
Fight the epidemic, get back to work and make progress. On February 19, Zhejiang energy Jiaxing No.1 maritime power project was resumed safely, which is one of the earliest projects of 9 key projects under construction in Zhejiang energy group. The project is a serious clean power project promoted by the provincial "13th five year plan" and one of the largest marine power projects under construction in the province.
"In order to get back to work as soon as possible, we will actively communicate and coordinate with the local government after the epidemic is relatively stable, and we will successfully get the reply to get back to work, and point-to-point chartered cars will be used to pick up the reworking personnel from other places." The person in charge of Zhejiang energy Jiaxing Haiyuan Power Co., Ltd. said, "on the premise of focusing on epidemic prevention and maintenance, we work together with all participating units to resolutely" grab "back the time and" burn "the enthusiasm for work!"! The goal of completing the first batch of units and putting them into operation in the year remains unchanged. ".
It is reported that in order to quickly finish the resumption of production, Zhejiang energy Jiaxing Hai advantage power Co., Ltd. has made precise strategies, rallied all efforts, and made a "combined fist" to strictly prevent and control the epidemic situation and promote the resumption of production. In response to the difficulties of tight project schedule and large work volume under the epidemic situation, the company made full use of the relatively independent characteristics of offshore construction, carried out the offshore construction and isolation investigation together, effectively advanced the time for resumption of work, and minimized the impact of the epidemic on the construction period. In the process of project resumption, the company received full support from the provincial development and Reform Commission and the local government. Ningbo Maritime Bureau and Jiaxing Maritime Bureau specially sent sea patrol boats to escort the safety construction of offshore projects.
Up to now, the jacket of the offshore booster station, a "giant" with a sea dominant power capacity of 900 tons, has been successfully hoisted, 8 offshore pile caps have been completed and pile driving has been completed, buildings such as the onshore metering station and the auxiliary production building have been completed, some equipment has been in place, and the project has been carried out orderly according to the specified objectives.
The novel coronavirus pneumonia party is being examined and directed by Tong Yahui, the party secretary and chairman of the Zhejiang Neng group, who told the scene inspection and guidance. He told reporters that in the critical moment of fighting against the new crown pneumonia epidemic situation, Zhejiang Neng group resolutely implemented the directive spirit of the Party Central Committee and the provincial Party committee and the provincial government, and strengthened the state owned enterprises' role in the battle of "two hands and both hands must win", and steadily promoted 9 key projects in the construction of the province. The novel coronavirus pneumonia prevention and control work and the resumption of work resumed operations will be promoted in the first half of the year, and we will firmly fight the overall prevention and control of the epidemic prevention and control, so as to provide the power guarantee for the end of the whole province's economic and social development goals.
As of March 15, all the serious projects under construction (including 9 provincial key construction projects) in the province of Zhejiang energy group have been fully resumed, with the intensity of resumption exceeding 100%. In 2020, Zhejiang energy group has a heavy infrastructure task, with the largest number of large-scale infrastructure projects and investment scale in the past years. In this year, Zhejiang energy group has 31 serious construction projects, with a total investment of 36.5 billion yuan, including 7 power projects (installed capacity of 1962000 kW) which have been completed and put into operation, and 3 natural gas pipelines (222 km in total) which are the final three-year action plan of "county to County (natural gas)".
