The Vectron2 Project: Turbulence Measurements for the In-stream Tidal Energy Industry
March 2019 – November 2021
The Vectron is a new sensor used for measuring turbulence velocity within a tidal turbine’s swept area. The Vectron has been successfully prototyped, where next steps are to take the technology to the ‘industry-ready’ stage of development and the focus of this project.
The Pathway Program: Validating reliable environmental monitoring for ocean energy projects
April 2019 – October 2021
OERA created The Pathway Program to solve a critical problem impeding the in-stream tidal energy industry: a lack of reliable and validated technologies and methods to monitor and report fish-turbine interactions in high-flow, highly turbulent environments, leading to regulatory uncertainty and i

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’.
Nova Scotia Small Tidal Test Centre: Gap Analysis and Business Case
November 2017 – March 2018
As the tidal energy industry develops, there is increasing interest in the prospects for small-scale tidal energy development. Building small-scale tidal energy installations has promise given the number of locations where they can be used.
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.
