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’.

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.

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.

Turbulence and Bottom Stress in Minas Passage and Grand Passage

September 2011 – February 2015

This project aimed to investigate turbulence and bottom stress at two sites being targeted for in-stream tidal power development in Nova Scotia: Minas Passage in the Upper Bay of Fundy and Grand Passage, located between Brier and Long Island in the 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.
