Research On Integrated Monitoring System Of Offshore Drilling Platform

Utilization and exploitation of marine resources become the world focus. However, exploitation of oil and gas resources in China is still lagging behind. Today, ocean engineering has been included in 12th Five-year Plan. Striving to develop the marine equipments is becoming the inevitable way to promote the ocean engineering. Semi-submersible drilling platform is one of most advanced offshore platforms in the world. It is an important tool of deep-sea resources exploitation. Offshore drilling monitoring system ensures security and efficiency of maritime operations. Because of equipment or system communication problems, traditional monitoring systems are often too scattered and confined in a small system or equipment. With the development of technology and increased complexity of drilling, it urgently needs a wide range of information sharing to realize integrated monitoring system of drilling.OLE not only provides a method to combine objects in different applications and different operating system into a powerful new application but also makes a program use another program service correctly. OPC (OLE for Process Control) is an industry standard based on COM technology. It not only introduces the object linking and embedding technology, but also provides a uniform data access mechanism. Applications access the data source in a uniform way and have nothing to do with the existence forms. It achieves the information exchange between basic equipment and process managements. Furthermore, it also increases software transparency.Taking dynamic positioning of semi-submersible drilling platform as object, the paper presents that application of OPC technology realizes integrated monitoring system of dynamic positioning in semi-submersible offshore drilling platform. The major work completed as follows:(1)Analyze and study not only working mechanism of dynamic positioning system but also device parameters.(2)Research information systems integration of heterogeneous network.(3)Study application of OPC technology.(4)Design and implement monitoring software of dynamic positioning in semi-submersible drilling platform.(5)Test monitoring software function. The monitoring system of dynamic positioning based on OPC technology unifies data access interfaces. Then, original distributed equipments and systems are monitored and operated on a unified platform to achieve the integration and sharing of information. So the safety, reliability and maintainability of dynamic positioning system are ensured. The automacity and management level of the drilling platform are improved to some extent.
