P.I. Frye （WHOI）提案#:0337893合作研究所：Chaffey （MBARI）提案#:0337888提案标题：合作研究：用于系泊浮标观测站的光电机械（EOM）系泊电缆的设计、建模和测试项目摘要：该提案用于开发和测试用于系泊浮标观测站全球网络的光电机械（EOM）系泊系统。这种EOM系泊电缆及其相关的机械和光电组件是系泊浮标观测站的关键技术要素，目前没有很好的定义，也没有商业制造商提供。这项工作的目标是为这个关键的系泊部件和相关的终端和连接硬件开发一种可靠且经济有效的设计。它将适用于全球大多数网络站点，在更换或维修之前的三到五年都是可靠的。现有的EOM系泊/电缆设计昂贵、不可靠，并且不能适应各种环境条件。此外，还没有可靠的测试方法来终止电缆，将其连接到浮标和锚，并调整其浮力以满足系泊配置要求。pi建议开发和测试一个完整的、集成的系泊系统，用于长期观测应用，该系统将提供在水面浮标和水下仪器阵列之间实时数据和电力传输的能力。技术工作将包括以下任务：1)为系泊浮标观测站设计和执行候选系泊配置的数值模拟，2)开发实验室测试程序，可靠地预测现场电缆和终端性能，3)设计EOM电缆，终端和应变缓解连接装置，4)对电缆样品进行实验室强度，弯曲和疲劳测试，5)开发预测合成EOM电缆疲劳失效的技术。6)制造和现场测试EOM电缆和系泊系统的原型；7)对系泊进行测量，收集电缆应变和弯曲的工程数据，以评估系泊和电缆的性能；8)对系泊部件进行部署后测试，以确定剩余强度，并将这些结果与疲劳模型的预测结果进行比较。

P.I. Frye (WHOI) Proposal #: 0337893Collaborating Inst: Chaffey (MBARI) Proposal #: 0337888Proposal Title: Collaborative Research: Design, Modeling, and Testing of Electro-Optic Mechanical (EOM) Mooring Cables for Moored-Buoy ObservatoriesProject Summary This proposal is for the development and testing of an electro-optical-mechanical (EOM) mooring system for use with the global network of moored buoy observatories. This EOM mooring cable and its related mechanical and electro-optical components is a crucial technological element of moored buoy observatories that at present is not well defined and is not available from commercial manufacturers. The goal of the proposed work is to develop a reliable and cost effective design for this key mooring component and the related termination and connection hardware. It will be applicable to most of the global network sites and reliable for periods of three to five years before replacement or repair. Existing EOM mooring/cable designs are expensive, unreliable and not designed for the full range of environmental conditions. In addition, reliable and tested methods for terminating the cables, connecting them to buoys and anchors and adjusting their buoyancy to meet the mooring configuration requirements are not available. The PIs propose to develop and test a complete and integrated mooring system for long term observatory applications that will provide the capability for real-time data and power transfer between surface buoys and submerged instruments arrays. The technical effort will include tasks to: 1) design and perform numerical modeling of candidate mooring configurations for moored buoy observatories, 2) develop laboratory test procedures that reliably predict cable and termination performance in the field, 3) design EOM cables, terminations, and strain- relief connection devices, 4) conduct laboratory strength, bending and fatigue testing of cable specimens, 5) develop techniques for predicting fatigue failure in synthetic EOM cables, 6) fabricate and field test a prototype EOM cable and mooring system, 7) instrument the mooring to collect engineering data on cable strain and bending to assess mooring and cable performance, and 8) perform post-deployment testing of mooring components to determine residual strength and compare these results to predictions of the fatigue models.
