The final jacket structure has been installed for the Beatrice Offshore Wind Farm.
Each of the 70 metre jackets weigh nearly 1,000tonnes.
A picture has been posted online by the Beatrice Offshore wind farm (BOWL) company, describing it as a milestone for the 84 turbine development.
The project in the Moray Firth is due to be fully operational next year.
In May, Scottish energy minister Paul Wheelhouse announced a Moray Firth wind development contract between Beatrice Offshore Wind Farm and Scottish firm Windhoist Group at All-Energy conference in Glasgow.
The deal, confirmed to be over £2million, will see Windhoist provide turbine pre-assembly to the SSE Beatrice Offshore wind project.
Contracted by Siemens Gamesa Renewable Energy, the deal will see over 40 local jobs sustained for the 10 month period of the project.
Mr Wheelhouse praised the completion of the jacket installation.
He said in a statement of social media: “Congratulations to the whole BOWL team for this – I am excited to see the project move forward to completion now that all jackets are in place and we can really see the project take shape.
“Best of luck for the remainder of the installation!”
