Unusual vessel hammers piles at 120 m depth
The project of the vessel, named Yihan Jin Zhuang, was developed by specialists of the Chinese company Harbor Engineering in close cooperation with China Communications Construction Corporation. The designers emphasize that the construction used parts, components and equipment mainly of domestic production.
According to Zhenhua Heavy Industries (ZHI), in addition to its record-breaking own dimensions (the length of the hull is 140 meters), the new vessel has the largest in the world, a 142-meter koprom, which is capable of driving piles at depths of more than 118 meters and is able to lift cargo up to 700 tons.
The giant piling vessel is designed for the installation of pile fields in ports and in the water area adjacent to them, the installation of stationary wind farms in the coastal zone and the construction of bridges, as well as other infrastructure facilities in the sea straits.
In addition to engines powered by traditional diesel fuel, Yihan Jin Zhuang is also equipped with electric motors that ensure its maneuvering directly in the work area, as well as a dynamic positioning system. The developers claim that the vessel is able to successfully perform its specialized tasks, including in open sea conditions, with significant wind strength and excitement.
