Comparative analysis on forecasting procedures of deepwater semi-submersible platform motion-response

Through designing the DP thruster system for a specific deepwater semi-submersible platform (Semi), this thesis searches for a reasonable way of DP thruster system design.

The motion performance and mooring system of deepwater semi-submersible drilling unit

Research on Structure Response of a Deep-water Semi-submersible Platform;

Constrain conditions of variables were defined according to the attainable information of semisubmersibles and design criterion,and a mathematic model of semisubmersible for ultra-deepwater was proposed and optimized by minimizing its heave response in head sea condition on the basis of combinatorial optimization.

This paper studies the damaged stability for upgrade of Nanhai-Ⅱ semisubmersible,obtaining the critical axis.

In this paper,four models are built based on a six generation semisubmersible,and study on hydrodynamic ability,stability,towing resistance and hull steel weight is carried out,which provides a reference for the design.

The paper puts forward six proposals for design of semisubmersible platform of deep water in our country upon the above concept.
