本技术报告为多相海底生产集输系统和注气系统泄漏检测的设计、操作、维护和培训提供了考虑因素和建议。范围仅限于使用内部过程传感器检测可从过程数据中识别的泄漏的方法。本报告不包括脐带系统、海底采油树（海底节流阀上游）、井下油管、注水系统和出口管道的泄漏检测。

This technical report provides considerations and recommendations for design, operation, maintenance, and training related to leak detection on multiphase subsea production gathering systems and gas injection systems. The scope is limited to methods using internal process sensors to detect leaks that are identifiable from process data. This report does not cover leak detection for umbilical systems, subsea trees (upstream of subsea choke), well downhole tubing, water injection systems, and export pipelines.
