On June 26, Shanghai Zhenhua Port Machinery (ZPMC) kicked off construction of the world’s longest spud legs, which will be installed on the 1,600-ton deepwater crane vessel project it undertakes for Guangzhou Salvage Bureau.
The Guangzhou Salvage Bureau’s 1,600-metric-ton deep-water crane vessel is a multi-purpose vessel capable of emergency response and salvage, wind turbine installation, and platform maintenance. It has a total length of 138 meters, a beam of 55 meters, a depth of 10 meters, a designed draft of 6.5 meters, and a crew capacity of 150 people. It is certified for navigation in all waters.
The vessel is equipped with four jack-up legs, each measuring 142 meters in length and weighing approximately 1,300 tons. The main structure of the legs utilizes high-strength EH690 steel, requiring extremely rigorous standards for welding precision and dimensional tolerances. Supported by these legs, the vessel is capable of jacking up in water depths of 90 meters and performing lifting operations at heights of up to 210 meters above the deck, significantly expanding the operational scope for deep-sea emergency salvage and offshore engineering projects in China.
As one of the core components of the Guangzhou Salvage Bureau’s 1,600-ton deep-water crane vessel, the successful commencement of the spud leg project lays a solid foundation for the subsequent assembly of the entire vessel and its sea trials.
