Hard to watch someone lying there dieing. Fortunately...

"he lived thanks to the efforts of his dive team and the high Partial Pressure of Oxygen in his bailout cylinders combined with the cold water which most likely caused his body to shut down to conserve heat and consequently the production of CO2.

He recovered fully."

Not sure he was lying there dieing, seemed to me to be lying there having an ox-tox, which continued till he blacked out from the cold. At least he couldnt spit his reg out.

Is that the plan in these situations? Infuse their system with high pp02 and then wait till they can be recovered and kick started?

When you originally read about diving accidents there is aways the persuasion call not to discuss it until some report or other comes out.
Speculation is the rally call tweet.

This is a follow up post to the one we discussed originally at the other place four years ago.
Now time we can finish it off with the official published report and the released video.

The Final Bibby incident summary is enclosed below

you should know that an 'official published report' produced by the company involved isn't worth the paper it's written on as nobody wants to admit their mistakes and want to be remembered as heroes and history is what gets 'officially' recorded.

I never saw it as the heroic rescue it was portrayed, more as a sequence of events where suddenly the holes in the cheese lined up leaving one poor bugger potentially paying the price for other people's mistakes.

MikeF, it's a shame you couldn't wade through all the documents and understand what went on that night. Bibby are almost unique in publishing the full facts from this incident, something they certainly didn't have to do- remember, within a month of this incident, one of the largest Diving companies in the world had 2 separate DP issues on two of their vessels which resulted in both colliding with platforms, one of which running into live risers. Another company in the North Sea had a total, unexplained blackout on their vessel when the bell was on the bottom, dragging it over all kinds of stuff, and had a fatality overseas a couple of years ago..try finding a report about any of those anywhere..

This incident was almost unique in that there was no 'finger trouble' or brain farts....the DP system basically shut down under an almost unique set of conditions, and the bridge crew did an incredible job bringing the vessel back to position to allow the rescue to begin. And if you don't recognise Diver 1's rescue as 'heroic' then you have never tried to climb an umbilical in heavy seas with a dead weight slung below you...

TDF isn't the place to discuss but I assure you I've waded through more than those documents.
