However, China\'s current research for mobile drilling platform design and construction technology is still in its initial stage, and the low efficiency of two-dimensional design method makes it difficult to meet the current design requirements.

As a mobile ocean platform,and owing to its high positioning capacity and good operation stability,the self-elevation drilling platform takes a leading role in continetial shelf exploration.

As the maritime moving platform, the self-elevation drilling platform is the main force in the exploration of the continental shelf as the result of good fixing and reliable working.

The historic development of jack-up drilling platforms is briefly presented,then the major models of deep water jack-ups are listed,and finally the innovations in deep water jack-ups are summarized.

This paper reviews the downturn and booming history of the offshore industry and the building of jack-ups,then surveys the current design and construction status of deep-water jack-ups,and also highlights the latest technological development in the new-generation jack-ups,finally provides the outlook of market demand and summarizes the progress of jack-up industry in China.
