P.I. Frye（WHOI）提案编号：0337893合作机构：Chaffey（MBARI）提案编号：0337888提案标题：合作研究：设计，建模，系泊浮标观测站的电光机械（EOM）系泊电缆的开发和测试项目摘要本提案旨在开发和测试电光机械（EOM）系泊电缆。全球系泊浮标观测站网络使用的系泊系统。这种EOM系泊缆及其相关的机械和光电部件是系泊浮标观测站的关键技术要素，目前尚未明确定义，也无法从商业制造商处获得。拟议工作的目标是为该关键系泊部件和相关终端及连接硬件开发可靠且具有成本效益的设计。它将适用于大多数全球网络站点，在更换或修理之前，可靠期为三至五年。现有的EOM系泊/缆绳设计昂贵、不可靠，并且不是针对全范围的环境条件而设计的。此外，没有可靠和经过测试的方法来终止电缆，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综合系泊系统，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进行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建模，2）开发可靠地预测现场电缆和终端性能的实验室测试程序，3）设计EOM电缆、终端和应变消除连接装置，4）对电缆样本进行实验室强度、弯曲和疲劳测试，5）开发用于预测合成EOM缆线中的疲劳失效的技术，6）制造并现场测试原型EOM缆线和系泊系统，7）用仪器测量系泊以收集关于缆线应变和弯曲的工程数据，从而评估系泊和缆线性能，以及8）执行系泊部件的部署后测试，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.
