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.
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.
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.
Assessing Corrosion, Wear, Fatigue and VIV on Moorings and Cabling to Reduce Risk in Marine Operations
October 2017 – August 2018
The cost of cabling and moorings over the entire life of a tidal energy project is a significant proportion of total project expenditures and the potential failure of these components remains a major risk for the emerging tidal energy sector.
Going with the Flow II: Using Drifters to Address Uncertainties in the Spatial Variation of Tidal Flows
October 2017 – June 2018
Drifters are one of the oldest, simplest and most reliable methods for measuring ocean currents. Drifters also provide a simple, low risk platform from which to gather acoustic information along flow streamlines or ‘drift tracks’.
In Situ Turbulence Replication and Measurement (InSTREAM)
October 2015 – January 2018
The In Situ Turbulence Replication and Measurement (InSTREAM) project was conceived to address some fundamental questions about the turbulence physics in tidal energy sites and laboratory tanks used to simulate these sites.
Turbulence Dissipation Rates from Horizontal Velocity Profiles at Mid-Depth in Fast Tidal Flows
December 2017
This study characterizes the turbulence in a tidal channel in the Bay of Fundy that has been identified for development as a tidal power resource.
