China Electric Power News: Touching Electric Power—Dance with Wind

Touching words: they, overcome the mental loneliness during those years of drifting life on the sea produces, the bio-clock disorder due to working with tide causes, and the difficulties and hardships that working in winter water brings to their bodies; they, only by two years, master the core technology of intertidal wind power construction—single pile base driving technology, which breaks the saying that offshore wind power is called as “noble project” and realizes offshore new energy with high building speed and low cost.
The two figures of “100 million” and “10 million” are extremely meaningful to each Chinese people. By the end of October, the total installed capacity of China Guodian Corporation surpassed 100 million kilowatts, among which wind power 10 million kilowatts, the symbolic WTG is located at Jiangsu Rudong Offshore (Intertidal) 150,000 kilowatts Large-Scale Demonstration Wind Farm.
To build offshore (intertidal) wind farm, most people have never heard about it, not to mention to see it. However, when rows of WTGs are seen in Rudong Huangang bund, with huge fans rotating and singing happily, the grand situation is amazing, and it’s really a miracle!
By its strength in wind power development field, Guodian Longyuan Jiangsu Offshore Wind Power Co., Ltd. becomes the pioneer of China offshore wind power industry. As the company’s main force—engineering construction department writes one miracle and another with its difficulty-tackling, keenly innovation and efficient team spirit.
In this September, CCTV’s program of “Go Grass-Roots” made Guodian Longyuan offshore (intertidal) 150,000killowatts large-scale demonstration project as report object of “12th Five-Year Plan” key project, and focused on the engineering construction team of Guodian Longyuan Jiangsu Offshore Wind Power Co., Ltd.
Brave enough to be the first man to “eat the crab” and make new breakthroughs
Located at intertidal zone 3-8 kilometers away from Jiangsu Rudong County Huangang bund, and with planed total installed capacity of 150,000 kilowatts, Jiangsu Rudong Offshore Wind Farm is the first national offshore (intertidal) demonstration wind power project. Compared with onshore wind power, offshore wind power is still in exploration stage. As an innovative project R&D team, engineering construction department of Guodian Longyuan Jiangsu Offshore Wind Power Co., Ltd. has no any successful experience to learn in various links from design, construction to equipment and so on, therefore the team faces one difficulty and another from staffing to technology.
In more than 10 personnel of the engineering construction department, only three to four of them are experienced in thermal power work but without experience in offshore wind power work, and the others are newly-graduates from university. Confronting with the tremendous difficulty of nearly zero starting point, the whole team just went forward bravely, they plied between intertidal zone day by day to study while exploring and practicing, investigated the actual situation of the beach, and gradually knew the hydrological conditions and law of Rudong intertidal zone very well, which laid a solid foundation for future offshore construction of the project.
Previously beach wind power in the world had always been in the stage of theoretical study, and never entered into actual operation stage. The engineering construction department visited many R&D units and design institutes, and referred to lots of data, and then proposed three kinds of intertidal wind farm plans: onshore construction, offshore construction, and both onshore and offshore construction, and the final construction plan was decided through repeated discussions and studies. By more than two years of prophase preparations such as investigations, consultations, beach experiments, computer simulation experiments and plan selection, etc., the shallow-drift aground flat-bottomed barge specific for intertidal wind power construction was developed, and the working idea of “transportation equipment by boat and moving site by construction boat when tide rises, and construction aground when tide falls” was decided, and then the offshore wind power building road in line with our national situation, hydrological, geological and costal conditions along the sea was formed.
