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.
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.
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.
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.
Analysis of Tidal Turbine Mooring Systems in Turbulent Flows Applying the (Wind Industry) FAST Simulation Tool and DSA ProteusDS Software
March – September 2018
For floating tidal turbine platforms, the turbine forces and resulting platform motions have a direct impact on the lifetime of its moorings and cables. This means the tidal sector must predict accurate tidal turbine loading on floating platforms to determine mooring life and cable longevity.
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.
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.
On-line Interactive GIS Map Platform: An Enabling Initiative for the Emerging Tidal Energy Industry
April 2015 – April 2016
A proof-of-concept Geographic Information System (GIS) platform was developed aiming at building a decision-making tool that integrates complex spatial information of importance to the tidal energy industry while also being scalable, flexible and accessible. The platform was built on open source

Physics of the Interaction between a Crab and a Seismic Test Pulse – Development of a Mathematical Model and Testing of Model via Simulation
June 2009 – September 2011
Experimental attempts to establish whether seismic testing has any impact on crabs and the crab fishery have been hampered by a lack of theoretical work on the subject.

Feasibility of a Marine Vibroseis System to Minimize Potential Impacts of Seismic Surveying on Commercial Marine Invertebrates
May 2010 – May 2011
Marine vibroseis (a sound generating system that uses a large oscillating mass to emit a range of frequencies) offers an alternative to air-gun seismic sources and may have fewer environmental effects on marine biota.
