Research On Key Drilling Equipment Monitoring System For Deepwater Drilling Platform

As the drilling depth and operating water depth of offshore drilling platforms continue to increase,the safety and reliability of drilling system are required to be higher.The key drilling equipment monitoring system of deepwater drilling platform ensures the normal operation of drilling equipment by monitoring the operation status of drilling equipment.It is of great significance to improve the safety and reliability of drilling system.Based on the high-tech ship research project of the Ministry of Industry and Information Technology,the key drilling monitoring system of the seventh generation ultra-deepwater drilling platform is studied.Firstly,taking the drilling equipment of the seventh generation semi-submersible drilling platform as the monitoring object,the hardware architecture of the system is completed by the research on the data transmission mode and the network structure.In order to improve the reliability of the monitoring system,the redundant structure is designed for the important parts of the system.Secondly,through ANSYS static analysis of dual derrick,the weak components of double derrick are determined,and the monitoring scheme of double derrick is completed.In order to find out the main failure sources of power equipment,qualitative and quantitative analysis of power equipment is carried out by using fault tree analysis method.Based on the analysis results,the monitoring scheme of power equipment is formulated.Then,the evaluation system of drilling equipment is established according to the monitoring scheme.Combined with analytic hierarchy process,a method is proposed for comprehensive evaluation of drilling equipment operation status based on the improved radar chart.In order to test the reliability of the method,the mud pump is taken as an example to evaluate the condition of drilling equipment.Finally,combined with the hardware architecture of the drilling monitoring system,the corresponding software architecture is proposed.Lab VIEW is used to develop and design the monitoring interface of the host computer to realize the functions of each module.
