中文摘要:
      张力腿作为张力腿平台(tension leg platform,简称TLP)的重要组成部分,服役水深大,动力学行为复杂多样。为了保障张力腿的结构安全,开展张力腿的水下全方位监测十分必要。文中以某TLP为依托,构建一套能耗最优的张力腿监测系统。首先,利用附加质量法对张力腿进行湿模态分析,结合有效独立法与模态置信度准则确定张力腿监测节点的具体布设方案;其次,以能耗最低为优化目标,基于遗传算法建立了水下无线组网监测方案,同时讨论了监测节点存在失效时监测数据传输路径改变方案;最终,得到一套能耗最优的TLP张力腿水下无线组网监测方法,以降低水下监测系统维护成本。
英文摘要:
      As the major component of TLP (tension leg platform), tension leg is long term in-service in the deep water and exhibits a complex mechanic behavior. In order to ensure the structural safety of the tension leg, it is necessary to carry out prototype underwater monitoring. Taking a certain TLP platform as an example, we established a wireless networking prototype monitoring system based on energy consumption optimal criterion. At first, a detailed layout scheme is presented for tension leg monitoring based on the efficient individual method and model assurance criteria together with the wet modal analysis considering the structural additional mass. Then, focusing on energy consumption optimization, an underwater wireless networking method is given based on genetic algorithm. The monitoring data transmission plan is studied when there is node failure during in the monitoring process. The data transmission path changing scheme is discussed with the monitoring node failing behavior. Finally, a set of TLP tension leg underwater wireless networking method with optimal energy consumption is obtained to reduce the maintenance cost of underwater monitoring system.
