该项目将与海洋可再生能源(MRE)资源评估和海洋可再生能源(MRE)资源评估机构Mavi Innovation合作 为了开发一种经济的潜水流量测量装置，用于 MRE资源评估。包括潮汐和河流入流(不使用堤坝或拦河坝进行蓄水 水)漂浮或淹没的涡轮机，它利用水的能量并将其转化为电能。水 流量测量用于进行资源评估，这是一个关键的初始阶段 任何MRE项目都是如此，因为它提供了对水中能源可用性的预先分析。一个合适的人 资源评估将有助于提供信息，以便对MRE站点是否进行财务分析 是不是发展的可行性。Mavi面临的具体问题是前期资源的高昂成本 评估，特别是在离网和偏远地区。现有的技术用来测量电流， 声学多普勒海流剖面仪(ADCP)，本质上是水下声纳，是复杂的和 价格昂贵，完全部署和回收仅一台设备的成本高达50,000美元。该项目将致力于 为MAVI建造一个锚定浮标系统，该系统将容纳几个当前的测量仪器和 较长时间内的创纪录速度，所有这些成本都大约是ADCP的十分之一。该项目将开始 在不列颠哥伦比亚省的湖泊环境或水槽中建造和试验浮标技术，然后是河流 在马尼托巴省的加拿大水力涡轮试验设施(CHHTC)或不列颠哥伦比亚省的河流中进行测试，具体取决于 出于后勤方面的考虑。最后，这项技术将在海洋潮汐环境中部署在几个 已确定的位于公元前坎贝尔河附近的名胜古迹。Mavi Innovation专门从事MRE 资源评估，并参与各种与资源评估直接相关的项目，包括在这里的两个地点的工作 在公元前。MAVI还建造了一台22千瓦的原型涡轮机，设计用于水面和水下 在河流和潮汐水道中部署，并持有几个潮汐场地许可证，以供可能的开发。

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.
