On October 28, the 5,500-ton double arm variable amplitude crane vessel “Erhang Zhuoyue”, designed and built by Shanghai Zhenhua Port Machinery (ZPMC) for CCCC Second Harbor Engineering, successfully completed its first mission on the sea level of Hangzhou Bay, one of the three largest tidal bays in the world.
This operation successfully deposited the steel hoisting box of the main pier No. 160 of the Hangzhou Bay Cross-sea Railway Bridge, which weighs 2,500 tons, is 25.1 meters high, 55.7 meters long and 40.2 meters wide, precisely to the predetermined position.
“Erhang Zhuoyue” is the most technologically advanced double arm variable amplitude crane vessel with the largest lifting capacity in China. The vessel has an overall length of 165 meters, a beam of 52 meters and a design draft of 6.5 meters.
Equipped with 3 sets of 3,350 kW main generator sets, 2 sets of 2,000 kW main thrusters, and 8-point mooring and positioning system, “Erhang Zhuoyue” has a lifting capacity of 5,500 tons, and is capable of navigating at a height of 47 meters.
The crane vessel introduces a green and energy-saving ship-wide grid management system on the engineering operation vessel for the first time. Meanwhile, it also adopts green energy-saving technologies such as photovoltaic energy storage, high-efficiency permanent magnet motors, operational auxiliary decision-making system and operational environment sensing system.
In addition, the vessel is characterized by strong operational adaptability which can serve bridge engineering, hydraulic engineering, as well as offshore wind power.
The successful completion of this “debut” once again highlights the strong strength and high level of ZPMC manufacturing.
