The highest point of the impeller of "Mingyang Tiancheng" is 219 meters, and the maximum width in the air is about 369 meters, which also broke the record of the height and width of the towed object in the domestic towing field.

The total installed capacity of "Mingyang Tiancheng" is 16.6 MW, consisting of two sets of 8.3 MW wind turbines arranged in a "V" shape. After the platform is put into use, it can be used in a wide range of sea areas around the world with a water depth of more than 35 meters. It can generate an average of about 54 million kWh of electricity per year, which can meet the daily electricity needs of 30,000 families of three for one year.

Towing is the operation of using tugboats to tow various non-self-propelled mobile drilling platforms, offshore wind power equipment and exploration equipment on the sea. The total distance of this towing operation is 191 nautical miles, and the towing time is about 72 hours. It is understood that in order to successfully complete this towing mission, Zhengli Offshore Engineering has dispatched a large main tugboat (Zhengli 18000) and 10 tugboats as well as emergency engineering ships and emergency diving teams, which are expected to arrive at the destination on the 14th.

"This towing project involves complex waterways and has extremely high requirements for professional skills and operating weather conditions. There is no experience from similar projects to draw on, and the overall operation is extremely difficult," said Gao Ling, vice president of Zhengli Offshore Engineering.

The company also took the initiative to communicate and coordinate with 23 relevant units and departments, and organized authoritative expert groups to discuss various implementation links of the project operation plan on many occasions, and invited experts from universities to prepare a feasibility study report on towing simulation, striving to achieve "zero accidents, zero injuries, and zero losses" in the towing project.

Zhengli Offshore Engineering is mainly engaged in marine engineering construction. It has participated in and successfully completed a number of national key projects, such as the Dolphin Tower of the Hong Kong-Zhuhai-Macao Bridge and the hoisting project of the Pingtan Strait Highway-Rail Bridge. It has also undertaken the construction of large-scale offshore new energy wind farms for a number of central enterprises and state-owned enterprises such as China Energy Construction. So far, the company has undertaken more than 25 domestic wind farm construction projects.

The launch of this towing mission not only marks a milestone in the field of offshore towing engineering for Zhengli Offshore Engineering, but also sets an example for the "three supers" (super-large, super-high, super-wide) towing operations in the construction of domestic wind power platforms, and provides valuable practical cases and experience.
