【摘要】：由于环境因素、设计缺陷、人为因素等原因导致的大型结构损伤事故屡见不鲜,结构健康监测技术对保障大型结构的安全运行具有重要作用,已在桥梁、大坝、场馆等许多大型建筑上得以应用。极端海洋环境以及长期服役容易造成海洋平台损伤以及疲劳失效,针对海洋平台的监测研究也有很多,国外的监测技术已比较成熟,国内的相关设备与技术相对匮乏。不同类型海洋平台结构相差很大,具体监测实施也不尽相同。我国渤海与南海的多座FPSO海洋平台由于服役时间过长,面临故障威胁,相关监测技术急需发展,而传感器以及各种数据处理方法的快速发展,为海洋平台监测打下了坚实基础。本课题基于与中海油海洋石油总公司合作的海洋平台监测项目,对海洋平台监测内容、监测技术、数据分析技术等进行了研究,提出了整体监测与局部重点监测,多种传感联合监测以及数字监测配合视频图像监测的集成监测方案,开发出一套针对FPSO的集成监测系统,对渤海的三座FPSO的环境信息、结构响应信息进行了全面监测。利用多种数据分析方法对监测数据进行了分析,针对FPSO单点系泊系统的模态参数时变问题,提出一种时变结构模态参数识别方法,对单点系泊系统模态参数进行了分析,为系泊系统损伤诊断打下坚实基础。目前,针对渤海三座FPSO的全面监测还在持续,获得了大量珍贵的监测数据,对于了解海洋平台的工作环境与工作状态有很大帮助,针对监测数据的分析结果对于指导平台安全生产具有重要作用,为我国海洋平台监测研究提供了重要的参考资料。
[Abstract]:Because of large structural damage accident It is often seen. due to environmental factors, design defects, human factors, plays an important role in structural health monitoring technology to ensure the safe operation of large structures, has been applied in bridges, dams, and many other venues large buildings. Extreme marine environment and long-term service are likely to cause damage and fatigue failure of offshore platforms. There are many monitoring researches for offshore platforms. The monitoring technology abroad is relatively mature, and the related equipment and technology in China are relatively scarce. The structure of different types of offshore platforms is very different, and the implementation of specific monitoring is not the same. Many FPSO offshore platforms in Bohai and the South China Sea are facing the threat of failure due to the long service time. The relevant monitoring technologies need to be developed. The rapid development of sensors and various data processing methods has laid a solid foundation for offshore platform monitoring. The offshore platform monitoring project cooperation with CNOOC Offshore Oil Corporation Based on offshore platform monitoring content, monitoring technology, data analysis and so on, put forward the overall monitoring and focus on local monitoring, sensing and monitoring a variety of joint monitoring digital video image monitoring with integrated monitoring program, developed a set of FPSO integrated information monitoring system, carried out a comprehensive monitoring response to environmental information, the structure of Bohai's three seat FPSO. Analysis method of monitoring data were analyzed using a variety of data, variable modal parameters for FPSO single point mooring system, variable structure modal parameter identification method proposed, the single point mooring system modal parameters were analyzed for mooring system damage diagnosis and lay a solid foundation. At present, according to the comprehensive monitoring in Bohai three FPSO, get a lot of valuable data, very helpful for understanding the ocean platform working environment and working condition, according to the monitoring data analysis result plays an important role in guiding the production security platform, which provides an important reference for offshore platform monitoring research in china.
