This project will engage with Mavi Innovations, a marine renewable energy (MRE) resource assessment and technology company, in order to develop an economical, submerged water flow measurement device for use in MRE resource assessments. MRE includes tidal and river in-stream (no use of dams or barrages to impound water) floating or submerged turbines which harness the energy of the water and convert it to electricity. Water flow measurement is used for the purposes of conducting a resource assessment, which is a critical initial stage of any MRE project as it provides the up-front analysis of energy availability within the water. A proper resource assessment will help provide information for conducting a financial analysis of whether a MRE site will be feasible for development or not. The specific problem Mavi faces is the high cost of up-front resource assessments, particularly in off-grid and remote areas. The incumbent technology used to measure currents, acoustic doppler current profilers (ADCPs), which are essentially underwater sonars, are complex and expensive, costing upwards of $50,000 to fully deploy and retrieve only one device. This project will aim to construct an anchored buoy system for Mavi which will hold several current measurement instruments and record velocities over prolonged periods, all for roughly one-tenth the cost of an ADCP. The project will begin with building and trialing the buoy technology in a lake environment or flume tank at UBC, followed by river testing at the Canadian Hydrokinetic Turbine Test Facility (CHHTC) in Manitoba or in rivers in BC depending on logistical considerations. Finally, the technology will be deployed in an ocean tidal environment at several sites of interest which have been identified near Campbell River, BC. Mavi Innovations specializes in MRE resource assessment and is involved in various projects directly related to it, including work on two sites here in BC. Mavi has also constructed a prototype 22 KW turbine designed for surfaced and submerged deployments in both river and tidal channels and holds several tidal site permits for possible development.

该项目将与海洋可再生能源（MRE）资源评估机构Mavi Innovations合作， 技术公司，以开发一种经济，淹没水流量测量装置，用于 地雷风险教育资源评估。MRE包括潮汐和河流内（不使用水坝或拦河坝来蓄水 水）浮动或淹没涡轮机，利用水的能量并将其转化为电力。水 流量测量用于进行资源评估，这是一个关键的初始阶段 这是任何地雷风险教育项目的一个重要组成部分，因为它提供了对水中能源可用性的预先分析。适当的 资源评估将有助于提供信息，以便对地雷危险教育场址是否 发展是否可行。Mavi面临的具体问题是前期资源成本高 评估，特别是在离网和偏远地区。用于测量电流的现有技术， 声学多普勒海流剖面仪（ADCP）基本上是水下声纳，结构复杂， 昂贵，仅完全部署和检索一个设备就要花费50，000美元以上。本项目旨在 为Mavi建造一个锚定浮标系统，该系统将容纳几个海流测量仪器， 记录长时间的速度，所有费用大约是ADCP的十分之一。项目将开始 在UBC的湖泊环境或水槽中建造和试验浮标技术， 在马尼托巴的加拿大流体动力涡轮机试验设施（CHHTC）或BC的河流中进行试验， 出于后勤考虑。最后，该技术将部署在海洋潮汐环境中， 在不列颠哥伦比亚省坎贝尔河附近发现的感兴趣的地点。Mavi Innovations专注于MRE 资源评估，并参与了各种直接相关的项目，包括在两个网站上的工作在这里 在BC。Mavi还建造了一个原型22千瓦涡轮机设计的水面和水下 在河流和潮汐通道的部署，并持有几个潮汐网站许可证的可能发展。
