Almost all scenes are inside a diving saturation system, covering all bell run on 26th September 2020, and few images in the water at 78msw, with poor visibility.
This video is to show quickly the routine of a dive team inside the chambers/bell but there are a lot of peaple working outside to keep everything functional and safe.
