webfact Posted July 1, 2018 Share Posted July 1, 2018 Biggest international rescue operation ever assembled in Thailand By Thai PBS The ongoing rescue operation at Tham Luang cave has become the biggest rescue operation of its kind ever launched in Thailand with the participation of divers and other rescuers from several countries. And the challenges facing them are a tough nut to crack as they have to race against time with the fate of the 13 boys and their coach hanging in the balance. Two Australian divers said they spent three hours to get to Chamber 2 and had to get out because they needed new oxygen cylinders. Two Japanese irrigation experts sent by Jica who have surveyed water draining operation have recommended the use of water jet to drain out the mud first which, they said, will help speed up the draining of water out of the cave.

I wonder how much pressure you would need to move the water, or rather assist in the drainage? And is the cave system sealed enough to attain that pressure? And more to the point, what effect in the raising of the pressure would have for people trapped in those spaces. Certainly not argumentative comments, just curious.

The report was that he wanted to see the permits for any drones being used in the rescue and that if they were used without the proper permits the owners could find themselves in trouble.

I'm really proud to see how much the Thai people have put into this. They really take care of their own when push comes to shove. Very proud to call myself a Thai citizen. 1 1 2 1 Link to comment Share on other sites More sharing options...
webfact Posted July 2, 2018 Author Share Posted July 2, 2018 Officials refilling 415 oxygen tanks for rescue divers By The Nation Officials have been refilling 415 oxygen tanks since late Sunday night to move them into Chamber 3 of the Tham Luang cave for Navy SEAL divers to use. The Thai Navy SEAL Facebook page reported that officials started refilling the supplement tanks that have been sent there with help from the public. Together with the current tanks, the officials will refill 415 tanks and the process would take 12 hours. The refilled tanks will be moved to Chamber 3 for the divers to use in their attempt to reach the T-junction and the so-called Pattaya Beach where the 12 young footballers and their assistant coach are believed to be stranded.

Popular Post lanista Posted July 2, 2018 Popular Post Share Posted July 2, 2018 (edited) The whole thing is out of control. There are thousands of army,police ,rescue workers dressed in a huge array of coloured outfits ,media and food vendors with carts attached to motor bikes. Rescue workers doing evacuation drills. Helicopters everywhere. The only thing i havent seen yet are hookers. Give it time , if theyre not there already. If these 12 kids had been killed in pick up truck accident on the way to the caves the tragedy would barely rate a mention in the press. This cave thing has taken on a life of its own. I was here when the Tsunami hit in '04, and yes, there were problems with farang rescue workers being questioned over visa issues and overstays.Most of that recovery work was paid by farangs, Australia even supplied the refrigeration units for all the corpses. I will assume all the farang teams at the cave fiasco will be paying their own way ; and don't overstay! Dont forget Thailand is run by the military. There is no real government anymore.Farangs are nothing here. Edited July 2, 2018 by lanista 7 2 1 Link to comment Share on other sites More sharing options...

Though a common technique used to de-water flooded ships during salvage operations, it requires the flooded compartment to be air-tight, as the air must reach a slightly higher pressure than the water to displace the water. In a cave system like the Chiang Rai cave, any overhead vents open to the outside and the massive volume of air required to displace the water would make this technique impractical. Hopefully, the pumping operations will continue to improve the conditions and the weather remains favorable... 3 3 Link to comment Share on other sites More sharing options...
Parsve Posted July 2, 2018 Share Posted July 2, 2018 "can anyone with applicable expertise weigh in on the idea of pumping air into the cave water as a way of displacing it"? One kind of an answer. There is an, among divers well-known technique, where you use a tube and blow low compressed air at the end of it. Both water and mud (and air) will go into the tube. To you who, about the picture of diving tanks and related text, suggest that it should be air, not oxygen, you are probably right, but it would not be wrong to use oxygen in this case as it is safe to use down to a deep of 10 meters and it will make the tank to be able to use 5 times longer before it is emptied. 1 1 Link to comment Share on other sites More sharing options...

Yes the police chief is being slammed by everyone in Thailand, even talk show hosts. On facebook page, there are countless posts about the police chief and memes made up bashing him. This guy can't be serious in wanting to rescue the kids. Edited July 2, 2018 by mike324 2 2 Link to comment Share on other sites More sharing options...
seajae Posted July 2, 2018 Share Posted July 2, 2018 (edited) scuba tanks are filled with air never oxygen, my worry would be that the air they are pumping into them could be contaminated with all the exhaust fumes and those smoking around the area. The compressor usually draws the air from an area where there is no chance of contaminants, many years ago at Mt Gambier a shop that filled scuba tanks for the freshwater caves(200') in the area was sued after a group of divers (with wealthy parents) got the narcs while diving, many argued it was caused by the lack of experience of the divers and the dive master as they went off the main shot line then panicked especially as many of us had been using the shops air refills for a few years. Seeing all the traffic around where these tanks are being filled doesnt really fill me with confidence the air being taken is would be all that clean.

Parsve Posted July 2, 2018 Share Posted July 2, 2018 Every marine in the word have closed oxygen diving equipment and usual diving tanks that are filled with nitrogen, for instance, 60/40 are in common use among sport divers as well. 1 Link to comment Share on other sites More sharing options...
Eric Loh Posted July 2, 2018 Share Posted July 2, 2018 With so many disasters happening in Thailand, a trained, fully equipped and dedicated disaster force should be formed like the Disaster Relief Agency Civil Force in Japan or the SCDF civil force in Singapore. Hope the next elected government consider this. 1 Link to comment Share on other sites More sharing options...
africasiaeuro Posted July 2, 2018 Share Posted July 2, 2018 I wonder if there was a need for my comments. I decided to post anyway. Upon seeing the huge logistics required, alone to fill 415 tanks of oxygen, I ask myself the question: How the heck did the group enter into a cave of this deep. They didn't have 415 tanks, but they went in with what? With nothing? Then the next question: By whom were they led? Some freaking unqualified jacka..s? The whole system ist so loopholed, I repeat my earlier fears. There isn't a person with competency. I see a disaster unfolding. Reminds me of a project I did in Ayudhya area, where second hand trasnport damaged machinery ( again the fault of incompetent people ) was imported at a 10 times inflated price, financed by a loan. Nobody was competent, the project Director was the lover of the owner, he had no skills but his butt. The subcontractors they chose inflated the price the usual 10 x, when I brought in a knowledgable Thai who offered the same work for 10 percent of their submitted price, he was silenced. The last straw was when the owner ordered a 500 KV transformer to be installed right in the middle of the factory. Chaos everywhere, this was the conditions to work with. There is no relevance between the two cases. Somehow, with smiles, they achieve their targets. The Billions enter the country in form of Tourists rip offs who are magnetized by fake smiles. I just pray the lost guys can be found soon, since all the Navy Seals and foreign personel is on the scene - the only chance to get them out. 2 Link to comment Share on other sites More sharing options...

Instead of making a wild guess/assumptions(google search) you should really ask someone that knows, oxygen is toxic at one atmoshere, gas combinations are used for deep diving only and is not common. Again we see someone that knows bugger all about it trying to sound like they do 4 1 Link to comment Share on other sites More sharing options...

Little benefit in using a 60/40 mix for such shallow diving as necessary in this cave system (60/40 mixes are used to shorten decompression times after long/deep dives). I agree closed circuit O2 rebreathers would give the divers at least 3-4 times as long underwater, but they're often more difficult to use in tight squeezes than regular air tanks. 2 Link to comment Share on other sites More sharing options...
