How Does Sound Travel in High Energy Environments? Effectiveness of Acoustic Monitoring Systems and Turbine Audibility Assessment
April 2017 – December 2020
The researchers are designing and implementing a long-term acoustic monitoring program to support tidal energy development in the Bay of Fundy. Specialized acoustic instrumentation was deployed for a two-month period in Grand Passage to advance understanding how turbulence affects the ability to
Advancements in technologies and techniques for tidal energy development
April 2017 – March 2020
This project was funded under the Natural Resources Canada Energy Innovation Program and supported research into innovative technologies and techniques to advance the tidal energy sector. The research was comprised of five unique research initiatives with focus areas in environmental mo
Reducing Costs of Tidal Energy through a Comprehensive Characterization of Turbulence in Minas Passage
October 2017 – March 2020
Turbulence is a significant issue at every site being considered for in-stream tidal energy development.
Performance validation of a remotely operated vehicle (ROV) in a controlled environment
June 2018 – October 2019
In the past few years, the Nova Scotia tidal community has augmented its marine operational capacity, but some unknowns and risks still exist and the cost associated with such operations are high.
Developing Enhanced Marine Operations (DEMO) in High Flow Tidal Environments
October 2017 – October 2019
Conventional subsea remotely operated vehicles (ROVs) perform poorly in currents exceeding 1.5 m/s. This is a key operating limitation in the success and cost of marine operations in the Bay of Fundy, where current speeds reach 5 m/s.
Multi-Scale Turbulence Measurement in the Aquatron Laboratory
July 2018 – July 2019
This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.
Testing of a New Turbine Blade Design and Blade Materials
July 2018 – May 2019
There’s not yet a standardized, optimal way of extracting power from tidal currents. That’s why many tidal industry technologies are currently being tested around the world.
Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions
April 2018 – April 2019
Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).
Turbine Wake Characterization
November 2017 – March 2019
Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays. In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings. It is thus desired to not just delineate wake
Acceleration/Particle Velocity (PA/PV) Measurement System Evaluation in a Tidal Environment
February 2017 – December 2018
The objective of this project was designing and running a field experiment to test the performance of the Particle Acceleration/Particle Velocity (PA/PV) vector sensor.
