Hot work on a live leaking gas pipeline in high pressure air deep under the sea. I do not think that I have ever written a more dangerous sentence in my life.
We used to have conversations with our technicians that sounded like that, and usually ended with "but at least it's not radioactive" or something similar, and they would come back with "Oh yeah, good point" (ie the job *could* be worse)
Love the weld test footage! There is very little of that level of high end weldor qualification testing shown on the internet. Those weldors are the best of the best (and likely paid accordingly).
@@properaussie331 do some research on aquiring AND keeping a 3.9 ticket. Look into how many 3.9's worldwide. You'll find your answer there as to how much they should be paid. BTW... im an ex Hyperbaric welder so owe no allegiances to 3.9's. But the fact they get weld bonuses used to grip me sometimes. But hey... good luck if you can swing it. We used to screw as much as poss out of bosses... esp after codings passed! 🤭
Most that commented badly on testing don't know or understand why they where testing ,they a lot more to it than just sticking two pieces of metal together ,tenacity, elasticity and so on filleting can have no fault all the way through ,all relevant testing done the right way and precise to make sure ,thorough job boys
Sincerely fascinating. Especially interesting was the welding and testing procedures. It would be interesting to see that in depth. 10 out of 10. Would watch again!
Taylor Diving & Salvage was one of the pioneers of this kind of work in the North Sea back in the mid 1970's. The oil companies had to prove that they could repair a pipeline at 1000 feet (300 meters) before the Norwegian government would allow a pipeline to be laid from the offshore oil rigs and across the Norwegian trench and on to land in Norway. This work shown here uses much more modern equipment but the same basic techniques and methods. This looks like much more shallow water.
Awesome Job, extensive testing and certification of welders.. fabrication of the sleeve and temporary fit up before sending to site of leak.. cool job. Huge repair bill I bet..
Highest bull is probably from the fucking idiots weld testing. Clowns can’t weld so they dedicate their life to purposely finding something to stop a welder from progressing in life
Saturation diving is no joke. The cartilage in their joints compress when they’re under pressure, so more non-on-bone contact. They live in habitat, under pressure, approximately 30-days at a time. These boys do a most necessary job, they get paid very well for it, but their career under pressure has a shelf life. If you meet a commercial diver at a bar, buy him a drink...he’s earned it. At the very least, you are guaranteed a good sea story.
As Jakarta people we never knew if those underwater pipeline who supply natural gas to Muara Tawar Powerplant and Industrial Area at Cikarang are leak a few years ago. Thanks for shared this video.
I've changed My mind. I want all the yellow painted safety orange, and all the orange painted safety yellow on the ship. Truly an interesting and informational video, wow. KUDOS crews.
I sit at home or go about my daily bits and for one minute I've never given much more than surroundings family friends etc, to think that this is going on as I moan as I'm 3rd in the queue, amazing.
I'm a Retired UA 342 Welder.....I NEVER took a Plate test to Weld on Pipe....Their Doing Bend tests and Die Check tests...We usually Did x-ray Tests...I Taped into live lines in the Refinerys quite a few times..We call them Hot Taps...In the Refinery the inspector comes up and U.T.s the live pipe they put a gel on the pipe the same as the use on Pregnant Woman and can tell how thick the live Pipe is...I usually asked the inspector to hang around while I First Light up on the pipe...It's alittle scary first lighting up on the live Pipe....If you Blow through your DEAD....As you can see I never Blew threw...
I was in the N. D. T. field for many years, and you're right, I don't know why they showed plate instead of pipe. Also showed magnetic particle and ultrasound test, as well as destructive, but no x-ray! I'm sure every pipeline weld you made was x-rayed right after completion. These industries and companies can't stand any down time, as I'm sure you know. Everyone waits for the 'accept', then jumps into high gear, right?
@@carlsaganlives5112 Its not just the welders that were being "tested". First off you have to qualify the process, fitment and weld procedures. A lot of the footage is related to that. Also much of the welding on the actual repair was the clam shell sections which would have been welded horizontally at the 3-9 positions. So those welder test plates shown would be applicable to that part. X-Ray would not have been viable on most of the welding. You have a pipeline, with a big sealing clamp on it, then a clam shell cover being welded over all that. No way you can X-ray through all those layers and achieve the sensitivity required. The Circumferential welds to the main line yes, but that's it. Modern UT phased array systems are now being accepted in place of RT in many cases/applications today. I was a Sat diver in the North Sea (2W Taylor/Comex/Rockwater) for 15 years. I was CSWIP/ PCN 3.9 UT qualified and an ASNT III in all the NDT disciplines and AWS senior certified welding inspector. I worked on many hyperbaric welding jobs and performed all the NDT and welding inspections.
It was remarkable..they make a room without water..like working on a field..and not even a leakage in the room..I wondered how do they sealed it properly..
Outstanding surface and subsea work. Excellent video, too - well produced and generally very clear about how the process came together. Question: was that a "weld off" toward the beginning on sample pieces of metal to see which welders you were going to bring to the work site?
Yeah ...I think the time devoted to all that testing is sort of a subtle advertisement ..or perhaps not so subtle for the companys perfectionism. Thats OK ... somebody paid a professional editing and production outfit to put this video together.... making a point of their competance and extreme quality comitment is ok
Really impressive. That is some high risk work but I'm sure much time is spent on all the planning details. They are very brave men doing that welding on a leaky undersea gas pipeline...
Cool job.. well done pipe repair by clamp using hyperbaric welder diving. I think using welder diving is most fix result than robotic system in subsea pipe welding. But there must be plus minus when we use welder diving or robot in subsea pipe welding.
Freshwater exact depth correct. Salt (ocean) water less depth for 24.5 atm. Around 810 Feet equivalent to 24.5 Bar. That gauge was reading "MSW 24.2" Meters Sea Water ~ 80 Ft. Cool stuff!
@@phideauxiii And Lowell. That was the day MY music died. With every new release I'd say with excitement I can't wait to see what's next and what will be for years to come. And WFC... the best live rock and roll album ever to come down the pike. We'd put that on at a party and any girl who jumped to it was defnly a girl who liked to get down... _if_ you kno whut I mean
I'd like to know the value of the gas or whatever that moves through that pipe every hour or minute........and the pressure the line operates at. Its totally astounding the dollar value that is generated when there is a moving flow. Also here there might be environmental spill concerns, although this line seems to be gas only , not the liability of oil transport.
@@kim79710 In wet mag, the magnetic particles are suspended in a liquid, which allows them to move around under the influence of the magnetic field induced by the yoke. Note the short short short life of the liquid and how quickly it flashes off....this is the developer for liquid penetrant test, not wet mag.
@@rcwarship No..the white "paint" is a contrast application (not a penetrant developer) and the "Wet Mag" solution is iron particles dyed black and suspended in a clear carrier liquid packed into an aerosol in this case. Applied onto the white paint it gives decent contrast. It provides a "wet mag test" with no required black light. Not as sensitive as the full fluorescent wet mag test but better than a dry powder technique.
This is exactly why men are paid more and I don't give a damn what anybody says. There may have been some women on the support team but I guarantee they weren't in that diving bell. This takes total dedication discipline and most of all bravery. One burn through one mistake of any type and they're all dead kaboom!
A lotta things i couldnt understand....how did the environmental chamber that the welders worked in seal around the pipe......? If the pipeline is "live" what kept it from leaking into the work chamber while they welded ? Apperently the work chamber was open on the bottom they were standing on a grid, in a bubble of air? And did I miss it ..but I didnt see the working depth ..... Nice to see lincoln welders in the weld shop......Thanks for posting this fascinating and informational video....my hats off to everyone involved !
A gas containment clamp was installed over the PLIDCO clamp to prevent gas leaking into the chamber. In addition environmental conditions were monitored constantly.
That ship was in San Diego Harbor mid March 2019 and I was curious as to what it did. Extremely dangerous work. Can’t imagine the cost to make this repair.
I imagine it's well worth it! :) ... check the Natural Gas Bills for 29,000,000 people ... they probably sell $10 million dollars of gas EVERY day through that pipeline alone.
@@MikeBaxterABC Yeah Mike i think you are right. The actual absolute actual cost of this very technical repair seems like it would be big big dollars to us ...the little guys and it is a big dollar amount , but its cost RELATIVE to the actuality of the huge pipeline being disabled.... allows the money to be spent tp get top quality team and support ....to keep those big big big dollars flowing through the line. Keep those suit wearing mahogany lined office bean counters happy !
I’m a welder always fancied it but couldn’t stand 3/4 weeks in the chamber would go off me nut,been stuck indoors for 3 weeks on covid 19 lockdown going out of me head and I got a garden to sit in,,there’s welders then there’s welders good luck you boys worth every penny
its just a job, the bigger deal you make it, the harder it seems. you do what is required, that is all. oh and dont think about anything else, like what your family is doing, playing golf ect
Most of those dudes testing for the job could probably manage most top side shops and work sites. They've essentially gotta be able to make big dog calls while below surface. Can't ask El Jefe to check your work when he's a couple hundred meters up.
I wonder why the welding was not done in (TIG). It seems that it would have less of a failure rate and easier to control than stick. A lot less grinding and prep work. Just wondering.
