China News Network Jiangyin, March 25 (Reporter Sun Quan) The reporter learned from the Jiangyin Municipal Government on the 25th that the first 1200-ton jack-up wind power installation platform "Zhenjiang" completed the handsome "first show" in Rudong, Nantong on March 24. : Hoisting a wind turbine with a total weight of 790 tons on the sea.

"Zhenjiang" started construction in March 2018, with a cruising range of 3,000 nautical miles, a capacity of 100 people, a platform with a maximum operating water depth of 50 meters, a deck operating area of ​​about 2,500 square meters, and can accommodate 3 sets of 6MW or 2 sets of 8MW fans , And can independently complete the installation of 6MW, 8MW-class wind turbines and other water engineering construction lifting, piling, lifting and transportation operations.

Compared with the traditional platform, "Zhenjiang" has three major advantages of efficient operation, complete functions, and flexible transitions. It is at the leading domestic level in scheme design, ship type, and crane technology, and has self-propelled functions, which can meet unlimited navigation. District operations.

At the same time, "Zhenjiang" also self-supported a 4500-ton continuous hydraulic lifting system, a 1200-ton pile-pile slewing crane, a 30-ton ship deck crane, a full-slewing rudder propeller device, a four-point anchor system, a hose winch seawater lifting device, Key equipment such as hoisting towers can show their skills in a special and harsh installation environment.

The "Zhenjiang" offshore first project is the Shengdong Rudong 400MW Offshore Wind Power Project (Bid Section II), which is contracted by CCCC Third Navigation Engineering Bureau. The project has an offshore distance of about 40km. Frequent typhoons, raging waves in winter, and few construction windows.

Facing such complicated sea conditions, the "Zhenjiang" showed its strength: using the lifting system to stabilize the huge hull, and then began anchoring and positioning, measured the point, and then lifted from the water surface to the predetermined air gap position, and raised the arm The rack began to be hoisted. The single blade of the hoisting fan is 78 meters long, 167 meters in diameter and 81 meters in height.

It is reported that "Zhenjiang" was built by Jiangsu Zhenjiang New Energy, a key industrial cluster enterprise in Jiangyin Lingang Development Zone. On December 13, last year, "Zhenjiang" was successfully delivered at Wuhan Ship Machinery Haixi Heavy Machinery Co., Ltd. located in Qingdao West Coast New District. (Finish)
