China Communications Group successfully developed the first drilling VFD control system in China

Recently, CCCC successfully developed the first drilling VFD control system in China and passed the communication test and software test. At present, the system has been successfully installed in "Zhenhai No. 2", which marks that China Communications Group successfully broke the monopoly of foreign technology and became the first domestic and the world's fourth manufacturing enterprise to fully master the drilling VFD control system technology.

Drilling VFD control system and drilling control system are two important control systems of drilling system. Among them, the drilling VFD control system is the “emergency system” for the operation of the drilling system. When the drilling control system fails and is not controlled, the drilling VFD control system can provide emergency measures to avoid major downholes. Accidents increase the safety and stability of offshore drilling operations. At present, the technology is monopolized by three drilling suppliers around the world, and the construction of domestic drilling platforms is passive in the price and commissioning cycle. Compared with similar foreign products, the VFD control system independently developed by China Communications Group has a simpler interface and more complete functions.

The successful development of the system not only provides a strong technical guarantee for the construction of domestic drilling platforms, but also enables pre-commissioning of major drilling equipment such as winches, top drives and mud pumps, and effectively reduces the construction cost of domestic drilling platforms.
