diving bell accident

[bat7j]

Why is the voice on the radio sounding like a cartoon character?

[anikidwolfy]

@bat7j helium is used in the gas mix to purge out nitrogen in their blood - nitrogen is what causes the bends as it makes small bubbles in the blood stream wich kills you.

[pureintellectual]

god i was fucking scared! i heard about what happened and i thought this was a video of it

[trebeansear]

I like the way the diver had to be told to close the valves but when he started looking he was lost .....BELL CHECKS AWESOME !!! ............

[catsareweapons]

Is there any actual footage of the Byford Dolphin disaster?

[geobenne]

Hey, It's Alvin and the chipmunks at 1:41

[LTDANMAN44]

what does blow yourselves down mean?

[graceman25]

Had a sale on 1/4 handles did they?

Don't cheap on mens lives.

[harrismagnum04]

yes its the gas mix, google it for expanation. one of the things I find amussing is that one of the only things you can make out that the diver says is "oh for fuck sake"

they are lucky guys thats for sure

[demonstrius3]

Just wondering, was the reason why they were talking all high pitched was because of the helium in their gas mixtures ?? :)

[Ironandtheshizzelz]

Even if i read the description of this vid, i still don't get it. What is happening? what would have happen if 40 seconds passed, would they explode?

[harrismagnum04]

basically yes after passing out and death

[masume21]

@Ironandtheshizzelz No, they would not explode, you'd have to have somthing like the byford dolphin incident for that to happen. They would have air bubbles form in their veins and they would die, but they would not explode.

[lawstsoul]

Glad they made it. These systems are so comples that you don't often know there's a problem until something goes wrong...usually with fatal results. Personally I'd want to throttle the engineer.

[bksharma1000]

ya this is sometimes happens in bell diving,it is not funny it is really scary when u r in the bell or on the penal for supervisors

[NAUIdragster001]

My theory is that the rapid decompresion foreced there testicles inward until they blew and turned the divers into donald duck and alvin

[rokkenroll]

Holy shit that was close, would not be nice to have another byford dolphin incident.

[SeadogDriftwood]

Thanks goodness everything was sorted out! One ":Byford Dolphin" incident is enough!

[YTviewer118]

Was alvin the chipmunk with you from 1:18-1:43, I seem to recall hearing him say "oh for fuck sake" haha

[navyryan103]

ood shit, i love it!!!

[mitchamus]

Is that someone on nitrox talking funny?

[leroymoorejr]

@mitchamus

Helium And Oxygen

[harrismagnum04]

they where on the surface not a "minor glitch"

[billythekidworks]

rapid decompression. Just as long as they were able to get back down to depth/pressure within that 4-5 minute period, that whole situation is just a miner glitch.

[PX213]

Dead man's handle has to be on the bilge drain line. That's normally the only thing venting to outside the bell that doesn't go back up to dive control to be able to be controlled by topside as well as in the bell.

[shoifo]

The valve was closed externally on the bell, not by the the divers in the bell. It had been there for 2 weeks, they fukced up and panicked.

[Janth]

talk about being under pressure.

[greatsinailove]

Anyone seen this clip, man get stinged by Box Jelly:

watch?v=rQWO8o4kGhQ&feature=re­lated

[ghujkk]

H O L Y F U C K! Diver's worst nightmare in a nutshell. Good guys though keeping their cool and saving themselves... otherwise the LSTs could have had a big ass strawberry jam situation to clean up.

[Professerfuckknows]

The supervisor really helped in that situation, obviously keeping cool,calm and collected. I wonder if the lads at the sharp end shut his mouth valve down when the door seal broke at the end of that Sat? Was there a requirement to decompress immediately after the 4 bar loss of pressure? HSE involved?

[bigbullbronco]

my theory is that he got sooo pised that the hit there nuts sooo hard or he is working with alvin and the chipmunks and gophers or the sea farted HARD

[shotfirer1972]

know what heliox is?

[LEOFALASCO]

been there....any leak i alway put on hat first (onbroad supply) we use to carry hp o2

[murkydiver]

nothing like getting bent in a bell!! Thank God the Bell tender was thinking. WHAT THE FU@# was the engineer thinking!!! SCARY STUFF!!

[thatguyfromengland]

Fillosofert, the high pitched voice is usually closed by having Helium mixed in to the breathing gas

[glhman222]

this

[fillosofert]

My theory is that the high pitch voices comes the fact that the air pressure pushes the testicles inwards. This leads to less production of testosteron. Its like a form of castration.

[bigbullbronco]

holy shit my stomach is on fire i am laufing sooo hard dude that is CLASSICCCC ive benn laughing for like  minutes OMG

[fillosofert]

They speak like donald duck.

[lilmissdiverchick]

well said ysh16

[TriumVirateABAP]

By the time you are preped and working teh North Sea, and the Gulf conditions most of the men have learned of every possibility of hazzards that could happen; specially with those with medical diving tech background. Expect the worst and be prepared for anything, and don't push your tables. The port stories. . .we've heard them all, it might seem exciting but hey, these are actual lives of men and women out there.

[vital2mi]

Good work...you did everything correctly.

Thanks~

[00MORDRED]

exploded to death?...that just sounds retarded.

:o)

[MagePoO]

It's true if it happens to be an explosive decompression. One of the 5 persons who died in the "Byford Dolphin diving bell accident" had all his internal organs ejected after an explosive decompression.

Source from wiki. Find out more about it -.-

[aussiediver2]

hope that guy got fired who ever fucked that up

[kaneetacourt]

He was killed by the diving bell...

[kaneetacourt]

The dudes in the byford dolphin =O

[Assassinjoe01]

Holy shit man...

[jdiver7]

holy fuck

[CarsonStryker]

its true. search byford dolphin on wikipedia.

[RolodexEnigma]

I looked that up. That sounds like a terrible way to die.

[assbutter]

its not the mix of inert gas, its the ata that causes the high pitch voice. try to wistle pass 20 feet.

[ElizabethAGreene]

This is incorrect. The distortion comes from helium in the breathing mix, which is less dense than air. All else being equal, increasing pressure (depth) increases density, lowering pitch, but that effect is trivial compared to the effects of helium.

[sniffle44]

Nope, take a pressure chamber ride with compressed air... below a pressure of 20 meters or so, your voice becomes distorted.

[ysh16]

i have been in enough hyperbaric chambers to tell u the high pitch voice comes from the increases in pressure, the mix has nothign to do with it, u can breath a regular air mixture to 100ft in the chamber and have the high rabbit voices

[gavkm27]

It's a combination of both,are you trying to say it has nothing to do with helium???

[stardustcreature]

Why does the guy in the bell sound like Donald Duck? ;p

[YaDad23]

lol

[Vinitachi]

It is when the pressure in a place (ie a plane or something) Goes up or down very fast (I think)

[videosfromhell]

wow at 00:10 they had major ass problems on their hands

[SH1FT1]

What does he mean by Blowdown?

[doctorspankluv]

Funny helium shit talkers ther. That was dun inna closet.

[SaleN22]

Fuckin creepy, that's why people stop diving and

go in the ROV industry!!!

[Stantzs]

Yeah, you invest in a good one and it will be with you till the day you die, but thats only on account of them all being death traps.

[jehjehjajamm]

It's not because of the gas mixture, allthough many people think so. The squeeky voice is actually from the effect the pressure has on the vocal cords/folds. Of course, if you use a gas mixture the effect will be enhanced sligthly. If you decend down to, say 50m, you will notice that you voice becomes more squeeky from 30 and down, even though you're breathing 21/79 oxygen/nitrogen.

[jehjehjajamm]

Sorry "of course, if you use a gas mixture with *helium* "

Doing a check list each day in a tight-as-h*ll bell can be a crappy task, but they had room and picked the wrong day to skip some of the points ;-)

[dieselscience]

To an extent BUT if you can breath 21/79 deeper than 100m I will come to see you get your Nobel Prize. Bells are for FAR more than just 50m.

[divecontrol007]

it is the gas mixture you muppet, air up to 50 meteres sounds virtually identical to surface. Helium, on the surface will make you squeaky... its the density of the gas that affects your vocal chords. Helium is far less dense than nitrogenl

[jehjehjajamm]

Sorry, misred one of the previous post(Nitrox - nitrogen). I have never dived myself with nitrox. If there is helium in the gas mixture that will ofcourse make their voices squeaky. But saying that air on 50m sounds vitrually identical to surface, thats not quite right. If you have done any chamberdives to 50m or deeper on air you would notice. Maybe not to the degree of those in the clip, but still.

[subsea777]

It's you thats the Muppet, air does affect your vocal cords under pressure if you have done a chamber on air you would know this, Yes helium also affects your vocal cords as well. (posted by a current saturation diver)

[divecontrol007]

yes funny man, done plenty of chamber runs, 60meters the deepest (on air), and there is no way you can confuse compressed air in a chamber with a helium mix.

and i also got a sat ticket...

[subsea777]

You said "air up to 50 meteres sounds virtually identical to surface" If you stand by this claim you are indeed a Muppet! sat diver! I think "your sat diving" takes place in your head.What vessel are you working on? and the correct term for the "mix" is oxyhelium"

[christianloader]

calm down you little kids, play nice.

[r0ck3tsm0k3]

I can tell you that air at 300 meters sounds like pixies and little glass bells! :)

What is the standard procedure after this kind of accident?

[frostedbuts]

@r0ck3tsm0k3

Air at 300 metres? Air at 300 metres is lethal. The partial pressure of the oxygen in air is considered toxic at roughly 70 metres from memory.

[graceman25]

@subsea777 Oxyhelium would be a type of strange cutting gas.

Heliox is a helium oxygen mixture. Helium is said 1st because it is the majority of the gas. its usually an 80- 10 ratio or maybe 86- 12, somewhere around there. It depends on the depth.

Its the same with Nitrox. Nitrogen is the dominant gas so we say the nitro part 1st.

Oxy-gen, heh, is what we call 51% oxygen and higher in an oxy nitrogen mixture. But thats confusing so we call it all Nitrox.

[ganzoontube]

I have never use a bell for diving, but this is a diver nightmares

[ranyjan]

they sound soo squeky

[harrismagnum04]

No idea what line was venting

[deepworker79]

I'm pretty sure you can hear the bellman say it was the flood up valve. There are only 1 or 2 you can open from the inside to depressurize the bell.

[expatinbrazil]

sorry mate, explain what valves the diver can decompress the bell again?

[deepworker79]

Well the Bell flood is the main one, it will have 2 valves in line and allow the trunking to fill with water when the bottom door is open, it will also let you reduce the pressure once on bottom to allow you to open the bottom door. When it is opened when the bell is sealed it will allow gas to escape wich is what i believe happened in this video.

[ourboyjack]

Flood up valve, the bell was modified and bell internal check list was not changed. The flood up now has two v.v's, one hull valve and another easier to reach one down the line. This was the one that was knocked as the hull valve was left open.... Sill stuff really.

This was posted on IMCA saftey notices about a yr ago..

[Berkcam]

I'm offshore at present and for some reason not getting audio on this, but it looks like the bilge-drain valve was kicked and as harrismagnum pointed out if some nutter took out the 'deadmans' handle valve they should be reemed with a hedge-hog, or worse! I'm glad they sorted it - switched-on guys eh?

[Speargrass]

A quarter turn instead of a dead man? okaaay... the lads opened a valve; shit happens. With three divers in the bell internal valve bell checks had to be completed and the bell run under way. How come the supervisor was unable to make up gas into the bell.

Just a question I am curious as well

[Speargrass]

Quarter turn valve? instead of deadmans valve okaaay....

Still doesn't explain how the supervisor was not able to get gas into the bell from sat control. With three divers in the bell that means the bell internal checks are completed and the bell run under way. The lads have knocked a valve, shit happens, wheres the topside backup gas? why is valve control with the bell and not topside?

Cheers Speargrass AKA Deepsea

[subsea777]

The only time the topside might have control of the blow down gas is when it is Left open when locked on the system, otherwise the divers control Blowdown and emergency gas. + only the bilge drain has spring loaded valve.

[Speargrass]

Doesn't happen when I run things. I am a saturation supervisor, the reason they lost 40 metres expalins why topside must have control of bell blowdown and exhaust.

[subsea777]

You must be on the only Sat system in the world where the supervisor has control of the blowdown/vent!!! The divers are the one's with control. The only reason the bellman could not blowdown was he had closed the hull valve in his haste to stop the gas loss.

The only supervising you do is in your BATH!

[Speargrass]

My handle is Deepsea at Longstreath dot com

Check my profile. I and a lot of other very experienced sat supervisors routinely take control of blowdown exhaust till the bottom door is open.

The fact that things got so screwed up and the supervisor was powerless to correct the situation just reinforces my veiw of this. I would venture I have a hell of a lot more experience than you ... bath ... thats funny ...

[Speargrass]

Just checked your profile Subsea777 you have a video "Nice Day for burning"  features Travis G and Dave P made by a mate of mine.

Diving is a smal world why don't you start a threrad in Longstreath and see what answers you get

[funkyalfonso]

Subsea777, That's what I was thinking. My last bell dive was in the 1980's but the blow-down valve was controlled by the diver. I do think the supervisor should have talked it through more to the diver as this situation can stop one's brain from proper action. The diver sorted it out but it could have gone wrong.

[Chuckjagermeister]

Ouch. I was ready for some foamy horror. Sheesh. Glad they got it when they did.

[HorrorShow86]

the squeeky voices make it less scary.

[paddytoscio]

What went wrong? Why didn't they shut down earlier themselves? 40 secs to realize you're losing gas is a long time.

[harrismagnum04]

Read the text it explains

They didnt know what happened cause if the correct valve was fitted this cannot happen.

[paddytoscio]

From what I remember, (and it has been a while now) every valve on the outside can be isolated from the inside?

Gotta agree with bfhsatrat here changing a valve on the outside would not affect their ability to shut down on the inside. With soops realising he cant blow them down it indicates its a prob with the main blowdown. What line was the valve on?

[harrismagnum04]

The valve was in the bell at foot level.

My point is the problem was caused by the incorrect valve handle more than the poor diver that knocked it open. If they died I'd be pointing fingers at the guy who swapped out the valve rather than the poor dead diver who knocked it open. If the correct "dead mans" handle was fitted the problem whould have never happend. Just dont like people jumping to conclusions and calling people "tossers" when they dont know the whole story.

[subsea777]

Wrong! The valve was behind one of the divers bailout bottles, Newly fitted the divers did'nt know about it.(not on bell Checks)And Only the Bidge Drain has a spring loaded valve fitted P.S they lost 40M.
