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.
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’.
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.
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.
Going with the Flow: Advancement of Drifting Platforms for use in Tidal Energy Site Assessment & Environmental Monitoring
April 2015 – August 2017
This research project aimed to apply a simple and low cost philosophy to ocean observation by developing an inexpensive low-profile surface drifter for use in initial assessment of potential tidal energy development opportunities. The project addressed limitations in the existing drifter design
FORCE Data Management System/User Interface
April – June 2017
This project defined a Data Management System (DMS) and user interface solution for use by FORCE.
Impact of Channel Blockage on the Performance of Axial and Cross-Flow Hydrokinetic Turbines
April 2017
This work investigates the effect of channel blockage on how axial and cross-flow turbines perform. The objective is to fill a gap in the literature on suitable blockage corrections for cross-flow turbines.
High-Resolution Numerical Model Resource Assessment of Minas Passage, Bay of Fundy
January 2017
Two numerical models developed by the Acadia Tidal Energy Institute are described. The models simulate the tidal flow in the Bay of Fundy, and in particular the Minas Passage. The models have different grid resolution, one suitable for site assessment and one suitable for resource assessment.
Numerical Modeling of Tidal Turbine Behaviour under Real Turbulent Tidal Flow Conditions
December 2015 – December 2016
Researchers investigated and numerically quantified the behaviour of a tidal turbine under turbulent unsteady tidal flow, using flow data collected in the lower Bay of Fundy (Digby area).
