2015年04月06日 16:47  点击:[]

Prediction technique for hydrodynamic performance and movement performance of the platform: Analysis of hydrodynamic performance of the objective platform will be completed; An integrated software system for analysis and optimization of collective performance of a semi-submersible drilling platform will be developed; The time domain nonlinear coupling analysis technique and the analysis software for hydrodynamic performance and movement performance of the semi-submersible drilling platform, the riser system as well as the mooring system will be developed.
Analysis technique for structural strength and fatigue life of the platform: On the basis of the structural strength checking and fatigue life analysis according to the criterion by certain code, analysis of impact for some important structures such as platform column and brace, etc. under deepwater condition will be carried out, analysis of fatigue life of some pivotal local structures in the objective platform will be carried out, analysis of structural redundancy of the objective platform will be carried out, and finally a ��Dummy load conditions-structural response databases�� software will be developed.
Full life long term effective anticorrosion technique: A full life long term anticorrosion technique based on combinative utilization of coatings protection, sacrificial anode cathodic protection and impressed current cathodic protection will be studyed rely on the objective platform; The full life long term anticorrosion technique and a scheme of the corrosion protection system for objective platform will be established.
