Use of high resolution sonar for near-turbine fish observations (DIDSON) - We@Sea 2007-002 [PDF]

open access: yes, 2010
In this study we investigate small scale distribution of pelagic fish within a windfarm by means of a high resolution sonar (DIDSON, Dual frequency IDentification SONar; Soundmetrics).

Investigating Tidal Stream Turbine Array Performance Considering Effects of Number of Turbines, Array Layouts, and Yaw Angles

open access: yesJournal of Marine Science and Engineering
The performance of a tidal stream turbine array can be affected by numerous factors. Investigating the connection between array power production and these factors will be helpful in improving the development of tidal stream energy.

Unsteady hydrodynamics of full-scale tidal turbines [PDF]

open access: yes, 2018
Due to the lack of full-scale measurements of the flow around tidal turbine blades, it is not clear if unsteadiness in the background flow can induce dynamic stall and the significance of this on the rotor’s performance. To investigate, we develop a model that couples dynamic stall, rotational augmentation and blade element momentum theory with real ...

Development of a contra-rotating tidal current turbine and analysis of performance [PDF]

open access: yes, 2007
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Misplaced fears? What the evidence reveals of the ecological effects of tidal power generation

open access: yesEcological Solutions and Evidence
Tidal energy is a dependable and clean power source that stands as a compelling alternative to fossil fuels. Despite this promise, tidal energy projects face barriers to practical implementation, and objections to proposed schemes often stem from ...

Reliability prediction for tidal turbines

open access: yes, 2021
Marine renewable energy has the potential to form a key part of the renewable electricity generation arsenal that is required for society to prevent catastrophic global warming. Device reliability is one of the great engineering hurdles facing the sector; operating cost effectively in the harsh open ocean is very challenging.
