随着我国海洋石油事业的发展，水下生产系统的使用范围越来越广泛。由于远离下游支持设施且受水深限制，需要通过远程控制实现水下生产系统生产，完成与平台控制系统的通信，因而控制系统的可靠性对水下生产系统的平稳运行起着十分重要的作用，在设备出厂、运输、安装、预调试等各个环节通过相应的测试确保控制系统的可靠性满足要求。以南海某项目为例,概述主要水下生产设施(采油气树和水下管汇)单体测试、出厂测试、界面测试、整体测试及预调试投产等相关内容，可为后续类似项目开发提供借鉴。

With the development of deepwater oil and gas fields, subsea production system is playing a more and more important role. With the limit of water depth and transport distance, subsea production system is operated by automatic control system with umbilical. Various tests are needed during manufacturing, transportation, installation and pre-commissioning in order to keep the reliability of control system. Based on some subsea production projects in the South China Sea, brief introduction is given for the unit test, factory acceptance test (FAT), interface test, integration test and pre-commissioning of the subsea equipment including Christmas tree and subsea manifold. This research could offer reference for other similar projects.
