The second of two giant experimental offshore wind turbines has been floated out into the Moray Firth.
The second turbine at Nigg on the Cromarty Firth
The first tower and its components were taken by barge from the former oil fabrication yard at Nigg on the Cromarty Firth last August.
However, the second was delayed by poor weather and a heavy barge needed to carry out the task was also diverted to another job.
The turbines are part of a renewable energy trial in Beatrice oil field.
The turbines weigh about 1,000 tonnes and - when one of their three 63 metre (206ft) long blades is pointing straight up - they tower 170 metres (557ft) above sea level.
A Scottish-based consortium led by oil firm Talisman and Scottish and Southern Energy (SSE) is behind the deepwater turbines in a £35m pilot.
