Development & Design of Large-tonnage and Great-height Hydraulic Continuous and synchronous Jack-up System
At present, as the increasing of ultra-large structures, the contradiction that domestic lifting equipments can not meet the requirement of ultralarge structures lifting has become increasingly prominent. Based on the need of ultra-large steel structures (offshore oil platforms) jack-up, using strength theory and finite element analysis, a hydraulic continuous jack-up system for ultra-large structures jack-up was studied in this article. A new control system, which combines mechanics, hydraulics and electrics, was presented. More particularly, the modules of speed control and multicylinder synchronous control for the ultra-large structures lifting was designed. In the WINCC environment, a human-computer interface (control software) was developed by VB to achieve the systems real time monitoring and synchronization control. All movements of the jack-up system could be controlled through the software. To conclude, the jack-up system consists of two parts: the mechanical support structures and the control system. The former can assure great height (10m or more) jack-up, and the later can accomplish multi-point (more than 4 points) synchronous jack-up.
