“…While this numerical model has been shown to significantly under predict the average KEF in several areas [2], it highlight the primary region where this resource is located. The possibility of harnessing this resource using Ocean Current Turbines (OCT)s has been a topic of multiple studies over the past several decades [3,4,5,6,7]. Several organizations have been developing devices to create electricity from this resource [8], with recent testing of experimental system conducted in both a tow tank [9] and offshore [10,11].…”

This paper investigates the possibility of using active individual blade pitch control for positioning moored ocean current turbines within an array. Using a numerical simulation of a representative ocean current turbine it is shown that harmonic blade oscillations with amplitudes of 1.5° can be used to displace an ocean current turbine laterally by a distance equal to one rotor diameter, when the mooring cable length is approximately 30 times the diameter of the rotor blade. For current flow directions that would result in a downstream turbine operating in the wake of an upstream system at a distance of 10 diameters, this technique could be used to reduce the power loss of the downstream system from about 50% (caused by the reduced flow speed available in the turbine wake) to the 1.2% power loss associated with the suggested control approach.
