Jacking Tower system, 2500 tonne capacity, China

In 2002 we were engaged to carry out the conceptual and detailed design of a new modular jacking tower system for the Chinese refinery construction market, to be owned and operated by No 4 Construction Company of Sinopec. The system uses strand jacks for vessel lifting and guying of the tower and was designed with many new features, including:

The new system carried out its first lift in early 2003. It was used to erect a 92m long, 763 tonne vessel in a chemical plant on the outskirts of Nanjing, China. (see below).
