Description
Technical Field
The invention relates to the field of design and transportation of multifunctional offshore operation ships, in particular to an offshore wind turbine integral transportation and installation ship and an offshore wind turbine integral transportation and installation method.
Background
At present, the offshore wind power technology is gradually improved, the development cost of an offshore wind field is gradually reduced, and the offshore wind power development becomes one of the main forms of the development and utilization of the current new energy technology. The development of offshore wind power technology is developing towards large-scale, high power and deep open sea. By 2019, single-seat offshore wind turbine power has evolved from 3 megawatts at 2010 to 12 megawatts. As the fan power increases, the size of the fan blades, the height of the tower and the weight of the wind turbine also increase. The highest point of the blade of the 3-megawatt fan is about 120 meters above the sea level, and the height of the highest point of the blade of the 12-megawatt fan from the sea level can exceed 200 meters. A larger-size 13-15 megawatt fan is expected to be put into commercial use in the middle 2020 s.
Offshore wind turbine structures generally include blades, nacelles, towers, and infrastructure. With the development of large-scale fans, the weight of blades, a machine room and a tower which need to be considered in integral transportation and installation is up to more than 2000 tons.
At present, the installation of an offshore wind turbine set adopts two forms, one is sectional installation, and the other is integral installation. The sectional type installation sequentially assembles the tower, the engine room and the blades on a pre-installed wind power base, and then carries out offshore debugging on the wind turbine generator. In the integral installation, the fan blade, the engine room and the tower frame are assembled and debugged on the shore base, and then are integrally transported to the wind farm sea area for installation.
In the currently completed cases, sectional installation is adopted more often. The sectional type installation is completed by adopting the self-elevating installation ship with the function of the crane, the self-elevating installation ship is limited by the self-elevating installation ship, the crane is designed in the past, the hoisting weight is small, the hoisting height is low, the navigational speed is low, the complex pile inserting and pulling operation is required to be completed before and after the hoisting operation, and the requirement on the operation sea condition is high. Therefore, the sectional type installation offshore operation time is longer, the requirement on an offshore operation window is higher, and the requirements on the seabed soil quality of the operation sea area are also met. Due to the limitation of the length of the pile leg of the self-elevating installation ship and the insufficient hoisting height, the self-elevating installation ship is no longer suitable for the development of deep sea wind power. In the case of integral installation, the installation is mostly completed by using a relatively expensive heavy lift vessel. The heavy lift vessel has poor motion in sea waves, the operation sea condition of the heavy lift vessel is higher than that of a self-elevating installation vessel, and the situation that the waiting period of an offshore operation window is long can occur.
In summary, the existing offshore wind turbine installation operation ship has the obvious defects of insufficient hoisting height, complex and difficult offshore operation, higher requirement on sea conditions and longer offshore operation time, and the development cost of offshore wind power plants can be increased.
