| 海底电缆的运行状况直接影响海洋工程的安全可靠运行,及时有效地掌握其健康状态具有重要意义。 海缆自身结构和
运行环境复杂,健康状态难以准确掌握。 为此,提出了一种融合在线监测数据的海底电缆综合健康状态评估方法。 首先,以电
缆状态评价技术导则为指导,融合海缆在线监测动态数据和巡检、试验等静态数据,构造适用于海缆综合健康状态评估的指标
体系。 其次,基于海缆在线监测状态量的特征,结合电缆导则评价标准,形成了一套合理、有据的评估准则。 然后,在上述基础
上建立多状态量融合的评估模型,分层对海缆部件和整体进行评估,得到海缆健康状态,并根据模糊理论量化状态,得到海缆综
合健康状态评估结果。 最后通过对某海上油气工程的海缆进行实例分析,验证了该方法的可行性和有效性。 |

| The operating status of submarine cables directly affects the safety and reliability of offshore engineering. It is of significance to
timely and effectively obtain the health status of submarine cables. Due to the complex structure and operating environment of submarine
cables, it is difficult to accurately obtain the health status of submarine cables. Therefore, a comprehensive health status assessment
method of submarine cables with online monitoring data is proposed. Firstly, following technical guidelines of cable status evaluation, an
index system suitable for submarine cable comprehensive health status evaluation is constructed by integrating static data, such as patrol
inspection and testing data and dynamic data from online monitoring. Secondly, a set of reasonable and evidence-based evaluation
criteria is formed based on the characteristics of online monitoring status of submarine cable and evaluation standards from cable
guidelines. Then, on the basis of the above, a multi-state fusion based status evaluation model is established, which can evaluate the
overall submarine cable as well as its components hierarchically to obtain its health status. Further leveraging fuzzy theory, a
comprehensive health status of the submarine cable can be obtained. Finally, the feasibility and effectiveness of the proposed method is
verified by applying on submarine cables in a practical offshore oil and gas project. |
