Norwegian energy giant Statoil has released a video highlighting the huge hook-up operation for the Mariner field.
Operator Equinor has 800 people working offshore to install the huge field around 95miles east of Shetland.
The £4.5billion project is expected to deliver 250million barrels of oil over a 30-year period.
Equinor has released a video outlining the scale of the hook-up phase, which is expected to take 2million working hours.
Production from the field is expected to begin later this year, with plateau production of 55,000 barrels of oil per day.
