Entering the Diving Bell
A technical diver enters the diving bell from the diving system he lives during the hyperbaric tie-in work for Nord Stream. Three divers will be lowered to the seafloor in this bell, where they work an 8-hour shift. The underwater welding work they perform is highly specialized, and there are about 30 divers worldwide trained to carry out this work. The welding work for the Nord Stream Pipelines was carried out in two sections at depths of 80 and 110 metres.
