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

Observations of Marine Mammals in Petit Passage and Grand Passage, Nova Scotia and Adjacent Waters in the Eastern Bay of Fundy to Assess Species Composition, Distribution, Number and Seasonality.

June – December 2014

This research project implemented a common mobile tool, database, and alert system for recording and acting on marine life sightings, while engaging coastal communities in protection of the marine environment and using crowd-sourcing to collect data for scientific research.

Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power

August 2013

Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy.

Passive Acoustic Monitoring of Cetacean Activity Patterns and Movements Pre- and Post-deployment of TISEC devices in Minas Passage

June 2011 – July 2013

This project aimed to conduct pre- and post- in-stream tidal energy device deployment assessments of marine mammal activity and to assess the potential risk for interaction with turbine infrastructure.

Cross Coupling between Device Level CFD and Oceanographic Models Applied to Multiple TISECs in Minas Passage

October 2011 – January 2013

This project aimed to develop a link between oceanographic computer models and Computational Fluid Dynamics (CFD) models in order to improve state-of-the-art modelling techniques used for resource assessments and tidal turbine siting for both single and multiple in-stream tidal energy devices.
