Umbilical severed at 80 meters in North Sea

Information is that he has recovered totally and is back at work see previous post.

This is also an interesting case that may shed some light on why he survived and the role keeping a clear head played in his survival.

Wow, that must one calm individual. 80m for 40 minutes on a single tank, how big was the tank, I cannot imagine it was huge. By staying calm and still, and somehow not shivering he kept his air consumption low while managing to stay consious just enough to hang on.
I have a lot of respect for professional divers.

A lot of people here were deeply concerned for days over the fate of someone we didn't know. It is somehow gratifying to learn that Chris Lemons is such an exceptional human being. Thanks for your post.

X 2 on that! We so seldom here "positive outcomes" and it is nice to know that this is one of them. Next time you run into Chris tell him he has a whole lot of supporters/fans on Scubaboard

Not knowing anything about this type of diving....how do they heat him after the rescue and he is not affected by the heat - causing nitrogen bubbles in his blood ? Forgive the ignorance.

Thank you . Now we also might get a slightly better idea...:cool2:

I know it is an old thread but here is a video of the rescue from the ROV camera.

@Akimbo you said something earlier in the thread about using 300bar tanks. Do they pump them to surface 300bar or 300bar over sat pressure? At those depth wouldn't the extra bump in the pressure have an exponential benefit to usable time? In the video the ROV got to the downed diver well before the recovery diver did would it be possible/feasible for the ROV to latch on to or grab hold of the downed diver and take him to the bell? Sorry for all the rediculus questions.

Do they pump them to surface 300bar or 300bar over sat pressure?

Most operators will fill over bottom pressure unless they are really shallow, like less than 100M/328'.

...In the video the ROV got to the downed diver well before the recovery diver did would it be possible/feasible for the ROV to latch on to or grab hold of the downed diver and take him to the bell?...

I don't know enough about the ROV on that boat to say... but the same though crossed my mind. I suspect that nobody expected a rescue at that point rather than a body recovery after all that time.
