The present invention discloses an offshore platform to achieve the best match for energy control systems of many offshore oil platforms and consumption of electric energy supply within the same area. Comprising a station level, a spacer layer and a network layer, station level features ensure that the entire offshore platform power supply, the power consumption reaches equilibrium with the monitoring system, equipped with spacer means for detecting the amount of electric energy supply and monitor, The network layer includes a network switch equipped with optical fiber communications and other communications and transmission means. The present invention is acquired on the platform energy supply and consumption data via the monitoring, communication, and feedback means summary provided three levels, to provide management systems to improve efficiency of management and production platform. The invention not only provides all the energy data query system, but also on energy consumption and production data, comprehensive analysis report query by curve analysis; and through the related management software, enabling managers to make the appropriate control measures and analysis more quickly.
