Abstract: With the development of offshore oil field, the cost of production and operation is increasing rapidly.Unmanned platform technology has been widely concerned in recent years because of its simple structure, less equipment and low production and operation cost. However, the unmanned platform mode also exposes the problems of high cost of workover operation, difficulty of boarding the platform and difficulty of equipment monitoring in the process of production and operation. The author systematically summarizes the experience of unmanned platform development by investigating the advanced technologies and excellent practices in the current unmanned platform development process, which aims to provide a reference for the further promotion and application of unmanned platform technology.
