脐带缆是水下生产系统内上部控制系统与水下生产设施的重要连接纽带。本文系统性概述了常规脐带缆预调试技术及关键测试设备仪器，有助于推动国内相关配套设备的研发，提升国内深水预调试技术服务能力。基于南海某气田工程实践，提出一套简约集成灵活的脐带缆测试流程，为后续深水脐带缆预调试实践提供技术支持。对比分析了两种不同类型的深水脐带缆水下预调试装备：以干预、修井&控制系统为代表的甲板测试装备与以水下增压模块为代表的水下测试装备。分析基于水下增压模块测试系统的深水脐带缆预调试技术局限性，并提出未来技术研发方向，最后指出其广阔的应用前景。

Umbilical is an important link between the upper control system and the subsea production facility. This paper systematically summarizes the conventional pre-commissioning technology of umbilical and key testing equipment & instruments, which is helpful to promote the research & development of relevant supporting equipment and improve the domestic technical service capacity of deepwater umbilical pre-commissioning. Based on the practice of a gas field in the South China Sea, a simple, integrated and flexible umbilical testing process is proposed, which provides technical support for the subsequent deepwater umbilical pre-commissioning. Two different types of subsea precommissioning equipment for deepwater umbilical are compared and analyzed: the deck testing equipment represented by intervention, workover and control system and the subsea testing equipment represented by the subsea booster module. The limitation of the deepwater umbilical pre-commissioning technology based on the test system of subsea booster module is analyzed, and the future development direction of its is proposed. Finally, its broad application prospect is pointed out.
