Design and Stability Study of 1000t Offshore Wind TurbineInstallation Platform

The offshore wind power generation has become a hot topics in the development of new energy sources. In order to meet the needs of the domestic and foreign market for offshore wind turbine installation device, TZ has designed the TZ40m-1000t offshore wind turbine installation unit which will be used for large power turbine installation. In this paper, the main design features of the unit from the aspects of general arrangement, critical parameters and main performance are described firstly, and then the stability performance of the unit is studied. The results show that the unit has excellent stability performance, especially for damage stability with greater safety margin. Based on the studies, following recommendations on the unit design are proposed from the aspect of stability. 1) To reduce the longitudinal arrangement of the key components exposure to wind; 2) The adverse effects caused by freeboard decreasing are more prominent when the center of gravity is lowered through the ballast. 3) Flooding angle increasing can greatly improve the intact stability of unit; 4) Side tanks play a decisive role in damage stability, and watertight integrity of intermediate tanks can be properly relaxed. The results and conclusions from this paper offer guidelines for future offshore wind turbine installation platform design and optimization.
