How many meters a minute?

Feeling along and laying guidelines behind you, maybe five or ten.

According to expert cavers familiar with this cave and local experts the cave maintains a steady 25C temperature. The water is cold but the cave, not at all.
 
 

I live in the real world, experts have said it's not cold! in that case the lads will be found alive and well!

all i wanted to do was post a photo i thought was interesting and showed the effort of the operation. can we please stop with all the posts about what is in the tank please! as I already said i copied and pasted the text from a translation. please give it a rest.

In Thai an oxygen tank would be Tang- Lom, the direct translation would be air  tank, so he translated it right ,as he said lets give it a rest, please  .

Smaller divers join rescue mission to navigate narrow passageway

Scuba divers relatively small in stature joined Navy SEAL divers on Monday in the push to reach so-called “Pattaya Beach” zone of the Tham Luang Cave where the 12 young footballers and their assistant coach are believed to be awaiting rescue.

 

Their smaller size would be useful in getting through the narrow underwater passage to Pattaya Beach, a rescue team source said.

 

Hope swelled among the crowd waiting outside the Chiang Rai cave, now cleared of unauthorised vehicles, that the 13 missing people would be found sometime Monday or early Tuesday.

 

Plans have been finalised for the quick delivery of medical aid to the group when they emerge from the cave.

 

The front of the cave now has a checkpoint where officials strictly limit attendance to authorised personnel only.

 

Several unauthorised people – including a woman claiming to be a spirit medium – have been shooed away to keep the area clear for the ongoing operation.

It just goes to show the exponential nature of the exercise, tanks for the trip in, tanks for the trip back, spare tanks for the next part of the journey, then tanks for the return to that point etc. 10 tanks to go one kilometre, then 20 tanks to go 2 kilometres etc, and all the tanks then need to be brought back out and replenished. The divers replenishing the tanks need tanks to make the round trip etc etc.

It doesn't take much imagination to realise that 100s and 100s of tanks are required.

Have you swam 500m in cold dark tunnels using scuba gear and hauling ropes to guide yourself out and spare air and lights?

The SEALs are amazing at their jobs but don’t make it sound easy.

Nothing is easy but it is down to the last 500 meter push and that alone would give the Seals a heart and soul willpower push. I am a very active and fit person and push my self to the limits all the time, not a geriatric wheel chair jockey calling shots from remembering child hood memories of PE. They will hopefully cover that distance within the last part of our day and I hope we, especially their moms and dads can cry in happiness and relief for once. 

Finding the kids is one thing.  The real challenge will be on how the hell do they get them out? More than likely, most of these boys don't really know how to swim, and would freak out trying to use SCUBA gear. So that would present a whole new set of problems.

I imagine if they get through with food, air, medical etc it would probably be a matter of just waiting it out for the water to recede.

This is what I am thinking. Why risk the kids in scuba gear for a journey that has been perilous for experienced divers.

I think concerns have already been raised about this issue and that the plan would not be for immediate evacuation but to stabilize and nourish the survivors first. Once they reach the kids I would imagine that drilling operations would be intensified as a possible better extraction method, foregoing the stress of having to use breathing apperatus.

That could be one very long wait.  The rainy season will official hit within a week, which will raise water levels inside the cave, despite their best efforts to pump it out.

& adding to that they also mentioned they may wait until they are in better shape after getting supplies to them

As far as the water receding they will need all the pumps they can get, especially if rain is forcasted 

& not forgetting they will be going with the current, not against which is part of the reason progress was slow

I tend to agree with chrisinth.  First, stabilize the kids, then proceed with a new drilling operation into the cave, where the kids could be hoisted out individually.

Wish they would get it right... "Compressed air"

Compressed Air Tanks... 

Quote

Air and Oxygen are the same thing. Facts: Air and oxygen are two separate things. ... Air is a colorless, odorless, tasteless, gaseous mixture, mainly nitrogen (approximately 78 percent) and oxygen (approximately 21 percent) with lesser amounts of argon, carbon dioxide, hydrogen, neon, helium, and other gases.

http://lgraba.tripod.com/id12.html

 

100% oxygen is likely to be fatal at a diving depth grater than 5 meters 

 

And I do not see any tanks even marked up enriched air/Nitrox (air that is enriched with oxygen).

 

Talk of 25 Degrees - I’m sure this is Celcius, not Fahrenheit. If it’s the latter we would not be finding these kids alive. I don’t think hypothermia is the issue as 25DegC will support life, it’s air and clean water. I also worry about their mental state after all this. Let’s just hope they have managed to stay alive then give them all the help they can get. Fingers crossed. It should not be long now.

As I understand it looking at the detailed cave survey maps, apart from the entrance series, the water flows from north to south (or from the T-junction towards Pattaya beach)... but it's not totally clear.

Depending on how tight the flooded passages are it may be possible to stretcher the kids out immobilized but wearing full-face BA sets.  Certainly less risky than being trapped if it rains again - but also depending on how much progress is being made in making access from above.

Of course its Celsius, that is the temperature scale the whole world uses, except for one country.

Navy Seals reach fork in cave that leads to Pattaya Beach

 

 

CHIANG RAI, 2nd July 2018 (NNT) - Navy Seals have reached the three-way fork that leads to Pattaya Beach where the 12 footballers and their coach are possibly located. 

Chiang Rai Governor Narongsak Osotthanakorn today delivered a progress report on the rescue operation, saying that the team will be able to make progress provided that no additional rainfall occurs. He revealed that the navy Seals had set up a base in the third chamber of the cave, bringing with them communications systems along with oxygen tanks. 

The Seals have since reached the three-way fork past the third chamber and will make their way towards Pattaya Beach where its hoped the 12 footballers and their coach are located. The mission now needs to expand a narrow passage that is situated before Pattaya Beach so that the team can set up another base. 

Meanwhile, officials on the surface continue to survey fissures that may provide more ways into the cave complex while engineers have pumped out large amounts of water. Due to the associated risks, controllers of the operation have decided not to drill for groundwater within the cave.

Gen Prawit believes SEAL teams will reach “Pattaya Beach” today

By Thai PBS

 

 

Deputy Prime Minister Gen Prawit Wongsuwon said this morning he believes members of the navy SEAL rescue unit will today reach the area in Tham Luang cave known as Pattaya Beach where the 12 missing young footballers and their coach are believed to be taking refuge. 

 

Gen Prawit also expressed hopes that the boys and their coach are still sheltering at the spot.

 

The 13 have been trapped in Tham Luang cave in the Tham Luang Khun Nam Nang Non National Park in Chiang Rai’s Mae Sai district since June 23. The search and rescue operation involving navy Seal teams and many other units as well as foreign rescue teams enters its ninth day today.

The passage leading to Pattaya Beach is on the left of the fork but the governor said with enough personnel, the SEAL teams will also attempt to advance toward the right passage.

 

One hopes that they already have started this mission. Don't put all your eggs in one basket.

And of course the good 'General' in charge of watch collections is a man with specialist knowledge of such rescue operations, when in truth he has just watched the news on TV the same as the rest of us !

It disappoints me that this is the first time (correct me if needed) that he has made any comment during this whole unfortunate and sad event.

 

Further, and disappointing and derelict, the national police chief has yet to make any comment or visit the area. Disgraceful. 

 

 

Lets hope they continue the pursuit for access/egress points, drilling, digging... finding fissures.  Stopping plan b,c,d,e is not an option, just because they are close to the "presumed" location of the kids.   

So I hope they find them safe. But all aside when they do, I sincerely hope Prayuth and Prawit don't say: We did it!

I personally don't need ANY comment from him anymore because everything he says I rate as lied.

Unless my kids were trapped in a cave, you couldn’t pay me enough to go cave diving. That is absolutely terrifying.  Scuba and free diving can be scary enough. 

500 hundred meters .

Hopes will be trashed. 

Or hopes will be fulfilled. 

Almost makes me scared to open the door.

Unless they are wet they should be fine, no wind down there and heat from the earth..

They are in a cave full of water!!! What are the chances they are dry?
