深水脐带缆作为连接海上平台与水下生产系统的关键基础设施，承担着电力传输、信号控制、化学药剂注入及液压动力供应等功能，其结构完整性对深水油气田开发安全具有重要影响。针对传统甲板测试装备存在的设备体积庞大、动复员周期长、租赁成本高昂等问题，本文基于功能集成化设计理念，提出一种水下液压测试监控模块的技术方案。通过建立多目标优化设计准则，采用模块化立架结构、三路独立压力测试监控系统及高精度数字记录仪表，实现了与深水脐带缆水下终端（UTH）的快速连接与在位实时监测。模块采用遥控潜水器（ROV）可操作接口设计，配备Hot Stab快速连接系统，支持多通路同步测试与数据记录。2021年在南海某水深700 m气田的工程应用表明，该模块海上测试周期可缩短至 1天，测试结果满足 ISO 13628-5：2009标准要求。本研究方案为深水脐带缆预调试提供了一种经济高效的技术方案，对深水油气田开发装备技术发展具有参考价值。

As the critical infrastructure connecting offshore platforms with subsea production systems， deepwater umbilicals serve functions including power transmission， signal control， chemical injection， and hydraulic power supply. Their structural integrity significantly impacts the safety of deepwater oil and gas field development. To address issues such as large equipment size， long mobilization cycles， and high rental costs associated with traditional deck-based testing equipment， this paper proposes a technical solution for an integrated subsea hydraulic testing and monitoring module based on functional integration design principles. By establishing multi-objective optimization design criteria， the solution employs a modular stand structure， a three-channel independent pressure testing and monitoring system， and high-precision digital recording instruments to achieve rapid connection with umbilical termination head （UTH） and real-time in-situ monitoring. The module features remote-operated vehicle（ROV） operable interfaces and Hot Stab quick-connection systems， supporting multi-channel synchronous testing and data recording. Engineering application in a deepwater gas field in the South China Sea （water depth 700 m） in 2021 demonstrated that the module can shorten offshore testing periods to one day， with test results meeting ISO 13628-5：2009 standard requirements. This study provides a cost-effective technical solution for pre-commissioning of deepwater umbilicals and offers reference value for the development of deepwater oil and gas field equipment technology.
