This is a mixed gas dive breathing helix, collecting debris from the seabed that had to be removed.
This is the most simple and easiest dive we did on the entire job, I basically just tender the umbilical from the bell, and diver 1 picks up some scrap steel pipes from the floor and puts it in a basket for the crane to lift back to surface... So no fancy clamp installations, or repair work and inspection on this dive. Hopefully it's still relatively interesting to see how the mixed gas works..
