The largest fully-slewing semi-submersible crane vessel “Siang Hang Yong Sheng” of our country was delivered in Jiangmen City, Guangdong Province. This is another “marine engineering equipment” added to the construction of a maritime power.
The “Sihang Yongsheng” crane vessel was constructed by Jiangmen Hangtong Shipbuilding Co., Ltd. of China Communications Construction Fourth Engineering Bureau. The deputy general manager of the company, Li Haifeng, introduced that the ship is 110 meters in length, 43.8 meters in width, and 8 meters in depth. It has a continuous flat deck of 4,800 square meters and is classified by the Chinese Classification Society. The “Sihang Yongsheng” integrates multiple functions such as semi-submersible transportation and full-rotation lifting. At the stern, it is equipped with a full-rotation crane with a maximum lifting capacity of 2,200 tons, which can not only perform lifting operations but also transport super-large and super-heavy offshore components weighing up to 20,000 tons. It is a “powerful tool” for port water engineering and offshore construction.
This vessel integrates multiple functions and can achieve “installation by hoisting + semi-submerged lifting + maritime transportation” in a single operation. It can efficiently complete the hoisting tasks of large-scale steel structures, wind turbine pipe racks, and heavy sections of bridges, etc., in the maritime environment. It is suitable for various complex marine engineering construction scenarios and effectively addresses the industry pain points such as the high difficulty of large-scale maritime component construction, low hoisting efficiency, and numerous operational restrictions. It provides equipment support for major projects such as cross-sea passages, port upgrades, offshore wind power, and marine engineering.
This ship is equipped with an automatic intelligent load adjustment system. Based on real-time sea conditions, ship body posture, lifting loads and other multi-dimensional data, it can calculate the optimal load adjustment plan, precisely adjust the water depth and inclination angle of each area of the ship, achieve autonomous balance regulation without human intervention, significantly enhance the safety, stability and accuracy of offshore lifting and loading operations, and improve the safety of offshore operations.
