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.
Tidal Energy: Strategic Environmental Assessment – Bay of Fundy (Phase I)
April 2018
This Strategic Environmental Assessment (SEA) provides advice on whether, when and under what conditions tidal energy demonstration and commercial projects should be allowed in the Bay of Fundy.
Drones and Drifters – The Great Pumpkin Race
October 2016 – July 2017
This project tested and developed a new low-cost approach to collecting oceanographic measurements for use in tidal initial site assessments. The plan combines one of the oldest tools in oceanography, the drifter, with one of the newest, the drone.
Advancing Tidal Energy Turbine Operations through High Fidelity Tug Propulsion and Control Simulation Software
November 2016 – March 2017
The project objective was to develop a numerical model of a tug boat and its propulsion system to accurately predict its dynamic behaviour in turbulent tidal flows.
Turbulence in Grand Passage Nova Scotia: Measures of Intermittency
April – December 2016
Turbulence research is very important to advancing the in-stream tidal energy sector, however turbulence in general is not well understood. Measurement at prospective turbine locations is essential prior to development, given the high degree of spatial variability between sites.
Spectral and Structure Function Estimates of Turbulence Dissipation Rates in a High Flow Tidal Channel Using Broadband ADCPs
January 2016
Spectral and structure function methods are implemented to compute the dissipation rate, ε, from broadband, diverging-beam, acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal channel.
Marine Renewable Energy: Background Report To Support a Strategic Environmental Assessment (SEA) for the Cape Breton Coastal Region, inclusive of the Bras D’Or Lakes
June – December 2012
In 2011 following a competitive request for proposal process, OERA commissioned AECOM’s Halifax office to undertake a Strategic Environmental Assessment (SEA) for marine renewable energy in Cape Breton.
Tidal Energy Resource Assessment Map for Nova Scotia
March – October 2012
This project used numerical simulations and theoretical calculations to predict not only the power that can be extracted from the flow through a passage but also the reduction in flow through the passage.
Mi’kmaq Ecological Knowledge Study (Phase 2)
May 2012
A second Mi’kmaq Ecological Knowledge Study was carried out prior to potential marine renewable energy development in the Brier and Long islands area of the Bay of Fundy, including Grand Passage and Petite Passage.
Assessing the Far Field Effects of Tidal Power Extraction on the Bay of Fundy, Gulf of Maine and Scotian Shelf
January 2010 – April 2012
The Bay of Fundy and Gulf of Maine system has a natural resonant period very close to the main semi-diurnal lunar tide. This results in the world’s highest tides and strong tidal currents in the Bay of Fundy, particularly in the Minas Channel and Minas Basin.
