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.

Advanced Analyses of the MIRROR-1 OBS Profile from Offshore Morocco
July 2017 – April 2019
This project completes an analysis of the OETR and OCTOPUS seismic lines collected from offshore Nova Scotia and integrates the MIRROR I refraction line from offshore Morocco to allow comparison of the conjugate margins using wide-angle refraction/reflection ocean bottom seismometer profiles.
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
Turbulent Scale and Wake Modeling on a Horizontal Axis Turbine
January – April 2015
This project aimed to accurately simulate turbulent flow over a scaled horizontal axis tidal turbine to resolve turbulence in the near and far field regions.

Establishment of Baseline Biological Data on Snow Crab (Chionoecetes opilio) Offshore Cape Breton for Future Assessment of Potential Impacts of Seismic Noise on Snow Crab
April 2012 – February 2015
The study investigates the impact of sound energy generated by acoustic/seismic arrays on snow crabs.
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.
