Broco Cutting In Sheet Pile

- During the construction of the new tunnel in Gothenburg, Sweden, one of our jobs is to open up the dock wall where the tunnel segments will connect to land.
Here you can see me cut a hole in one of the sheet piles on 3 meters water depth (9 feet). This was done to fill up the pile with water. The actual cut of the piles is done at 15 meters (45 feet) but the suction from the Delta P made it almost impossible and dangerous to cut. The suction made it very hard to cut since the water flow cooled down the metal. I needed to keep the rod close to the work piece at all time.
Fast forward to the end to see the actual hole and the suction from the Delta P.
This was done using Broco® Underwater Cutting System. The diving was performed in an AH5 free flow helmet in mid water.
Delta P is the reason I won’t get into underwater welding. Holy shit that’s terrifying
Sounds like a long fart. I think I laughed for the entire video. Thanks!
You ruined this video 😂😂😂😂
Lol
I want to insult your looks, intelligence or maybe your choice of life-partner... but I can't as you're right!
It's a real rasper like when you sat on the plywood chairs in high-school! ;-)
@@TeddyBear-ii4yc HAHAHA Thanks for the laugh as I needed one today!

Bud, when you feel down: 02:19 to 02:29
:-)
Wait, is that fire underwater?
P.S. did you lose the rod at 4:40?
Hello Tomek!
I guess you could call it a fire. It is a rod with an alloy of some metals connected to a welding machine and pure oxygen. The welding machine sets it on fire and the oxygen helps it to burn at around 5.500°C/10.000°F. Which is enough to melt the almost anything!
No, I did not lose the rod. I dropped it to show you the suction from the pressure differential :P
Thanks for asking!
@@MatsBengtsson
Wow, check out the differential in the suction pressure! ;-)
Only kidding Bud. :-) You can see the water rushing thru that hole! Is it rushing in to a tank on the ship?
What measures did you take to ensure you didn’t get killed by the delta p?
Hello DRCA!
This was one of the measures. We cut out a small hole higher up, just a couple of meters below surface. Which I'm doing in the video here. Then, we waited for the pipe to fill up before we made the final cut at 18 meters (59 feet) depth.
When in doubt stack it out
damn what did you cut through the gates of hell?,,,say is this a hollow tube with continuous power while making the work or does it have rods packed in it and you only use the power to light it ?
this is what 100k a year looks like
Is it a type of welding rod used for cutting at high temperature? Any accidents happen with pressure? Or ever had to make the deeper cut after someone else cut first hole... and then second guess yourself or colleague while making the second deeper cut?
Damn what did you it for dinner?
Hej,
Vad gör du för att förhindra dig själv från att sugas in och proppa hålet?
My screen has a permanent mark in now lol im serious aswell
My son liked this..lol
You seem to use an aquadyne helmet. What was the depth?

You should eat less beans.
