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.

Advanced Analyses of the MIRROR-1 OBS Profile from Offshore Morocco
July 2017 – April 2019
This project completes an analysis of the OETR and OCTOPUS seismic lines collected from offshore Nova Scotia and integrates the MIRROR I refraction line from offshore Morocco to allow comparison of the conjugate margins using wide-angle refraction/reflection ocean bottom seismometer profiles.
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.

Advanced Coastal Mapping to Support Hydrodynamic Modelling
April 2016 – June 2018
Nova Scotia’s Atlantic coast exhibits a variety of shorelines that may be vulnerable to contamination in the event of an offshore oil spill. In turn, variable currents, changing water levels, shoals, and exposed seaside conditions make effective spill response difficult for tidal inlets.
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’.
