China commissioned its largest lifting-capacity fully revolving semi-submersible
crane vessel, Sihang Yongsheng, in Jiangmen, Guangdong on July 8. Operating in a
full-rotation mode that allows 360-degree crane work while anchored, the vessel
can lift ultra-large, overweight components including offshore wind jacket
foundations, large steel structures and heavy bridge segments. Built for complex
marine engineering, it is intended to address industry constraints such as
difficult installation, low lift efficiency and operational limitations.
