EMEC redeploys tidal kit

Upgraded turbulence monitoring pod installed off Orkney

Orkney’s European Marine Energy Centre (EMEC) has redeployed its bespoke integrated monitoring pod for measuring the impact of turbulence on tidal energy devices.

The upgraded kit is fitted with an innovative system to enable tidal developers to optimise device design so that technologies can withstand the effects of strong tides and currents.

The sensor system combines standard flow measurement technology (acoustic and electro-magnetic) with novel non-acoustic measurement technology (shear probes).

The pod also features Valeport current sensors installed alongside a recovery system developed by local marine contractor, Leask Marine, which negates the need for divers operating in a tidal situation.

EMEC engineering technician Donald Sinclair said: “The pod was successfully deployed during a recent period of neap tides in a short weather window and is now feeding live data back to our data control centres in Stromness and Eday via a subsea cable.”

Integration of the new instruments on the pod has been made possible thanks to the InSTREAM (In Situ Turbulence Replication Evaluation And Measurement) project led by Canada’s Rockland Scientific.

The project was funded through a transatlantic partnership between Nova Scotia’s Offshore Energy Research Association and Innovate UK.

Prior to deployment, the pod was fitted with a MicroRider turbulence system designed by Rockland Scientific.

UK-based FloWave TT, Ocean Array System and Canadian companies Dalhousie University and Black Rock Tidal Power are also involved in the InSTREAM project.
