基于西门子3项控制技术的海洋钻机控制系统

概述了HZ19—2/3海洋钻机模块的结构及其与陆地ZJ70D系列钻机的区别。介绍了西门子(SIEMENS)人机界面(HMI)、可编程序控制器(PLC)、PROFIBUS-DP现场总线技术在海洋7000m直流电驱动钻机控制系统中的应用;电控系统的设计特点及网络控制系统软件、硬件的构成;监控系统的功能,控制系统的优点。HZ19—2/3海洋钻机通过了美国船级社的认证,2套钻机控制系统运行半年多来,性能优良,易于操作,对确保海洋钻井平台钻井安全、经济地运行起到了良好作用,标志着国产海洋钻机技术水平和开发能力有了新的提高。

Control system for offshore rigs based on Siemens technique

The modular structure of HZ 19-2/2 offshore rig and the difference between it with ZJ70D series drill rigs are described, the application of Siemens man-machine interface (MMI), programmable logic controller (PLC) and PROFIBUS-DP field bus-bar in 7 000 m DC driven rig control system is introduced, and the characteristics of the design of electric control system and the compositions of the softwares and hardwares in the network control system and function of the monitoring system and advantages of the control system are also introduced. HZ19-2/3 offshore rig iscertificated by American Bureau of Shipping (ABS), 2 sets of rig control systems have operated for more than 6 months with good performance and easy operation, by which safety drilling and economic operation of offshore drilling platform are guaranteed. It is indicated that the level of China's offshore drill rig technology and its development capacity are newly improved.
