Study on the Representative of the Water Temperature Observed by Coastal Observing Stations of China;

According to the actual needs,we analyse overall requirements of the oceanic automatic observation system,select the sensors,make the design proposal to complete the whole structure of the system.

Through many engineering projects, this paper compared the differences of the high tide level between the designing of a-hundred-year return period and the surveying in the ocean station, the designing of a-hundred-year return period in the engineering point and the surveying in the reference station .

Detection of offshore platform structure crack based on frequency response function;

Dynamic reliability analysis of offshore platform considering fatigue failure;

Research on fuzzy logic control of structural vibration for offshore platforms based on random uncertainty factors;

State of the art of structural optimization for offshore platforms;

The paper discussed collectivity layout design of semi-submersible offshore platforms according to active-correlated graph method based on the human factors engineering and put forward a new design scheme according to principle of human-machine engineering.

An improved crack detection method using modal frequencies of jacket platforms;

An improved crack inspection method based on modal parameters was presented for identifying a crack in a jacket platform.

Crack detection procedures using different modal parameters are analyzed for identifying the crack location and magnitude in a jacket platform.
