Abstract: Crude oil export pump is the key equipment of offshore oil production platform. The stable operation of export pump plays an important role in the stable production of oil field. During daily startup and use,it is more and more inconvenient to grasp the degree of startup and monitoring during use because the field and central control cannot view theelectrical parameters of the export pump. From the deep level,the central control of the platform cannot effectively and timely monitor the parameter changes of key and important equipment. There are also hidden dangers in equipment operationand the failure rate of equipment increases. The multi-function meter was selected to transform the medium pressure plate equipment,and the remote transmission and central control display of the electrical parameters of the crude oil export pump was realized, and the problem that the central control cannot view the electrical parameters of the export pump was solved.
