See drone footage of the now decommissioned Strangford Lough tidal turbine which sits in Portaferry, Northern Ireland.
The turbine, owned by Atlantis Resources, was first lowered into place in 2008.
It was reported that it would be removed at the end of 2016, but is still in place today.
The turbine’s two horizontal axis turbines are anchored to the seabed and are driven by the powerful currents resulting from the tide moving in and out.
