A giant wind turbine at Hunterston in Ayrshire is to be blown up in a controlled explosion.
The 177m-high (580ft) turbine had been used a test site for offshore wind farms such as the massive Beatrice field in the Outer Moray Firth.
The other turbine on the Hunterston site was dismantled by a crane last year.
But operators SSE Renewables said no safe method of dismantling was possible in this case.
It intends to carried out a controlled felling on 19 September, weather permitting.
The National Offshore Wind Turbine Test facility at Hunterston was established in 2012.
The 193.5m-high Mitsubishi 7MW Sea Angel turbine was decommissioned last year.
The 6MW Siemens offshore wind turbine will now also be demolished.
SSE said the test site had been instrumental in securing Scotland’s place as an international leader in offshore wind energy research and development.
Once the site is cleared it will be handed back to landowner Peel Ports.
