Equinor launched a video of the hook-up and commissioning operations on its Mariner platform in the UK North Sea. 800 people are working offshore on the huge hook-up operation to prepare the platform for production.
Mariner is the largest field development on the UK continental shelf in recent years. The time needed to connect everything on a platform is called a hook-up, and takes several months, and Mariner A is now in the middle of its hook-up phase.

In North Sea, Mariner A is rising more than 250 meters from the seabed and weighing nearly 40,000 tonnes. Eight large modules have been assembled and what it remains is the technical job . The large modules must be connected down to detail so that everything is linked.
Since Mariner A doesn’t have room to accommodate so many people, there is a floating hotel, a flotel, positioned alongside. The flotel Safe Boreas is connected to Mariner A by a gangway.
