In order to study the interaction effect between three buoys of wave power platform of "Haiyuan 1", we’ve made a research to that wave power platform in real sea conditions. We tested respectively the motion curve of different buoys, calculated the average delivered power, and analyze the interaction effect of buoys. We hope that the experimental result can provide technical support for the arrangement of wave power platform buoy.

The paper introduces the hydraulic jack-up system design about the first domestic self-installing product platform. According to the production platform features, the jack-up system chooses the mode of hydraulic cylinder driving. So the jack-up system is both economy and safe reliability. The jack-up system is equipped with proportional valve and the PLC programmable controller which has a touch panel to show the inclination of the platform, the synchronism of hydraulic cylinders in the four legs of the platform, the state of the piston pin and the alarm indication of the hydraulic power station etc.
