Two basic types of open-ocean platforms have been identified for use in the Global component of the ORION Program - the discus and spar buoys. The designs of candidate discus buoys have advanced to the point of deployment of prototypes off the Pacific Northwest and Monterey Bay whereas the spar design has not progressed beyond the 6- year old DEOS. The PIs request funding to provide an updated design and cost study of the spar buoy. The proposed study will be based on 1) specific spar locations established through the NSF's Request For Assistance (RFA) process and subsequent public scientific forum 2) recent experience with the installation of several spars with polyester moorings; 3) new fabrication methods for spars, especially the cell spar; 4) experience with float-over decks on spars; 5) the huge increase in costs for anchor handling tugs and platform supply vessels in the past year; and 6) meteorological and wave data (hindcast) for the three sites identified as prime candidates for spar deployments. They will develop design concepts for a high latitude spar - a particular challenge in such a harsh environment, but a high priority site for Ocean science. The proposed design update will also focus on methods for installation and servicing of the buoys. In particular, we will examine the tradeoffs between wet-towing and dry-transporting the spar to its deployments site. Broader ImpactsThe results of this proposal will be an extremely valuable resource and reference on the state-of-the-art of spar buoy designs for the ORION Program and rest of the ocean community. With the increased interest in ocean observing systems for not only research but for operational applications, an evaluation of the ability of the spar buoy design to meet power, structural, deployment, mooring and servicing requirements in remote and/or harsh environments will be of very great value to the ocean community world-wide. The proposed activity will advance the objectives of ORION which is expected to significantly promote teaching, training and learning as related to ocean observations, data and a greater understanding of the ocean and its socio-economic applications in general.

已确定两种基本类型的公海平台可用于ORION方案的全球部分-铁饼形浮标和圆柱形浮标。候选铁饼浮标的设计已经发展到在太平洋西北部和蒙特雷湾外部署原型的程度，而浮筒设计尚未超过6年的DEOS。PI要求提供资金，以提供柱形浮标的最新设计和成本研究。建议的研究将基于：1）通过NSF的援助请求（RFA）过程和随后的公共科学论坛确定的特定Spar位置; 2）最近安装几个带有聚酯系泊的Spar的经验; 3）Spar的新制造方法，特别是单元Spar; 4）Spar上浮托甲板的经验; 5）去年锚处理拖船和平台供应船的成本大幅增加;以及6）被确定为Spar部署的主要候选地点的三个地点的气象和波浪数据（后报）。他们将开发高纬度Spar的设计概念-在如此恶劣的环境中是一个特殊的挑战，但对于海洋科学来说是一个高度优先的地点。拟议的设计更新还将侧重于浮标的安装和维修方法。特别是，我们将检查湿拖和干运输筒状平台到其部署地点之间的权衡。更广泛的影响本提案的结果将是一个非常宝贵的资源和参考国家的最先进的浮标设计的猎户座计划和其他海洋社区。随着人们对海洋观测系统的兴趣日益增加，不仅用于研究，而且用于业务应用，对柱形浮标设计在偏远和/或恶劣环境中满足动力、结构、部署、系泊和服务要求的能力进行评估，对世界各地的海洋社区具有非常大的价值。拟议的活动将推进ORION的目标，预计将显着促进与海洋观测、数据相关的教学、培训和学习，以及对海洋及其总体社会经济应用的更好了解。
