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.

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’.

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.
