Offshore wind power rush to install! Sany "Red Wind Power Group" is the busiest!

Under the long-term plan of "carbon neutrality", the future direction of energy development is bound to make green and low-carbon as the primary goal. Compared with onshore wind power, because of its proximity to the load center, it is convenient for on-site consumption, and the resource reserves are sufficient, and offshore wind power may become the main force of wind power growth. "

At 23:30 on December 4, with the last impeller firmly located on the 100-meter-high tower, Longyuan Jiangsu Dafeng H4 offshore wind power project was successfully concluded. Forty-seven 6.45MW offshore wind turbines are about to feed a steady stream of clean electricity into the grid. Trinity SCC19000TM trackscraneAs an important hoisting equipment, it undertook the installation task of 6 wind turbines.

At the same time, not far from the SCC19000TM, Sany SCC12000TM and SCC4000A are working for the Longyuan Jiangsu Dafeng H6 offshore wind power project, and a huge "big windmill" has been erected along the coast, forming a unique landscape.

Offshore wind power hoisting is a complex system project, and it must be stable in the face of disturbance factors such as wind speed and surges. In order to have a suitable window period, all personnel are always ready for war, and it is common to wait for ten days and half a month. At the same time, they have to watch all the time, because once the window is reached, they have to race against the clock.

The installation process of the 6.45MW wind turbine is complex, and it is easy to shake with the tower in the case of swells. Therefore, the construction equipment must be safe, stable and fast, and grasp the best hoisting time. In addition, it is currently the last month of offshore wind power hoisting and installation, and various owners are accelerating construction, and the operation efficiency of hoisting equipment is more important.

Zhang Zhifang, the technical director of the project of China Energy Construction Jiangsu Electric Power Construction Co., Ltd., introduced: "The rear counterweight suspension technology of Sany crawler crane is very suitable for construction operations in the narrow space of the semi-submersible platform. The equipment does not need to be repeatedly disassembled in the process of rotation and walking, and in the case of a short construction window, it is of great help to improve the efficiency of hoisting construction。 ”
