摘　　要：水下生产系统结构空间跨度较大,不同组件运行环境存在很大差异,多个组件采取相同维修策略会影响维修方案制定的准确性,容易导致过维修或欠维修的问题。另外,组件之间存在相关性,某组件的故障可能导致相关组件的加速退化。针对上述问题,开展主控站、液压动力单元、水下采油树等水下生产系统关键装备的视情维修方法研究,考虑经济依赖性、环境依赖性等组件关系。将系统分成多个子系统,针对不同复杂程度的系统提出不同维修策略,建立考虑连续退化和随机冲击作用的组件失效模型,提出不同复杂程度维修策略的选择流程。结果表明,组件间的复杂关系极大影响了维修策略的选择,更准确的维修策略可降低系统维修费用,提高系统可靠性。Due to the large spatial span of the subsea production system structure and significant differences in operating environments among different components,adopting the same maintenance strategy for multiple components can affect the accuracy of maintenance plan formulation,potentially leading to over-maintenance or inadequate maintenance issues.Additionally,there are interdependencies among the components,where a failure in one component can accelerate the degradation of the associated components.In response to the aforementioned issues,research is conducted on condition-based maintenance methods for the key equipment in subsea production systems,such as the master control station,hydraulic power unit,subsea Christmas tree,etc.The component relationships such as economic dependencies and environmental dependencies are considered.The system is divided into multiple subsystems,and different maintenance strategies are proposed for systems with varying levels of complexity.The component failure models that consider continuous degradation and random shocks are established,and a selection process for maintenance strategies of different complexity levels is proposed.The results indicate that the complex relationships among components greatly influence the selection of condition-based maintenance strategies,and more accurate maintenance strategies can reduce system maintenance costs and improve system reliability.
