Design & Research of a Continuous Jack-up System for Large Structure Object

Nowadays, in order to do research on the petroleum in blue water, the demand of jack-up system for large structure object is higher and higher, but the jack-up system in our country is hard to meet this demand. The system mentioned in this paper can make great contributions to jacking large structure object up. In this paper the lifting theory of jack-up system is introduced in detail. The design and research of the continuous jack-up system is also mentioned in this paper. Moreover, finite element analysis is the core of this paper. The finite element analysis of jack-up system in each working condition confirms that the continuous jack-up system is doable. The continuous jack-up system for large structure object is of great significance in blue water petroleum industry.
