The Ocean Guardian left the Cromarty Firth in November
A drilling rig is expected to complete its journey from a firth in the Scottish Highlands to the Falkland Islands in the next few weeks.
The Ocean Guardian has been under tow by a tug since late November when it left Invergordon on the Cromarty Firth.
AGR Petroleum Services will use the rig during a £2m oil and gas exploration project in the North Falklands Basin.
The work has involved the largest consignment of gear to be shipped from Aberdeen to the region.
About 9,000 tonnes of equipment was loaded at Aberdeen harbour for shipment to the Falklands.
Desire Petroleum and Diamond Offshore Drilling are also involved in the project.
