What are the risks and challenges during the installation process of wind turbines?

The risks and challenges faced during the installation process of wind turbines mainly include the following aspects:

1、 Security risks

1. Lifting risk: The components of wind turbines are bulky and heavy, with engine compartments weighing over 200 tons and blade lengths exceeding 70 meters. During the lifting process, there may be safety risks such as breakage of lifting straps or steel ropes, damage to lifting ears or tools, and even injury from falling objects from high altitude.

2. Collision risk: Due to the size and weight of wind turbine components, there may be a risk of collision causing damage to wind turbine components during installation.

3. High work risk: Especially during blade installation, it is necessary to work at a higher position, which poses a safety risk for working at heights.

2、 Quality risk

1. Installation accuracy risk: The installation of wind turbines requires high accuracy. If there are problems such as tower bolt torque tightening not meeting standard requirements during the installation process, it will affect the installation quality of the entire wind turbine, and in severe cases, it may lead to wind turbine collapse and tilting accidents.

2. Corrosion prevention risk: Offshore wind turbines face environments with strong salt spray and rapid corrosion. If bolt corrosion prevention is not done properly, there will be significant quality risks.

3、 Progress risk

1. Weather factors: Force majeure such as typhoons and thunderstorms may restrict the installation progress of wind turbines and prolong the overall installation period of the project.

2. Transportation and delivery risks: There may be a risk of delayed arrival of components during the separate transportation of wind turbines, and the failure to effectively connect the processes may also lead to an extension of the installation period.

4、 Technical challenges

1. Geological conditions: The geological conditions of wind farms are diverse, including weak foundations, complex strata, etc., which pose challenges to foundation construction.

2. Modular design and rapid assembly technology: Due to the size and weight of wind turbine components, modular design and rapid assembly technology are required to reduce the difficulty of transportation and installation.

5、 Environmental and safety management challenges

1. Environmental protection requirements: The construction of wind farms needs to take into account environmental protection requirements and adopt appropriate environmental protection measures to reduce the impact of construction on the surrounding environment.

2. Safety management: Strengthen safety education and training at construction sites, widely apply safety monitoring and warning technologies, and ensure the personal safety of workers.

To overcome these risks and challenges, a series of measures need to be taken, such as strengthening safety management, improving installation accuracy, adopting advanced foundation treatment technology and modular design, and planning construction processes and human resources reasonably. At the same time, strengthening cooperation within and across industries, sharing experiences and resources, promoting technological innovation and cooperation are also important means to address challenges.
