Nord Stream Hyperbaric Tie-ins
HTML-код
- Опубликовано: 13 сен 2024
- The Nord Stream Project is installing two 48" gas export pipelines from Vyborg in Russia to Greifswald in Germany, through the Gulf of Finland and the Baltic Sea. The two pipelines run in parallel and each have a total length of approximately 1220 km. The total transport capacity of the lines is 55 billion m3 per year.
The first of the two lines was completed with two hyperbaric welded tie-ins performed by Technip in Norway and Technip's divers in 2011. One tie-in in Finnish waters, one in Swedish waters. A parallel pipeline has been laid and the hyperbaric tie-ins will be performed during the spring/summer of 2012. First gas was delivered in September 2011.
This type of work is mindblowing. I didn't realize until today that actually sink & de-water a dry habitat/environment that welders work inside to do parts of the job.
how about the part inside pipe?
Really nice video, impressive! Maybe I missed it - but what happens to the plugs? Are they removed through the pipeline itself afterwards? Thanks & cheers
Perhaps they didn't think about it. Haha, that's the real reason, we are freezing in Germany.
The plugs are called pigs. they can be remotely controlled to loosen their grip, then they are pumped along the pipe to a pig catcher, where they can be removed. Look at pigging videos - flexible pigs are amazing.
This is perfect engineering work
We take for granted the amazing things that humans do to maintain our way of life. The processes that go into designing, manufacturing, and building our infrastructure are impressive.
Check the dates in your write up, see your last sentence. Great construction job.Congratulations from Canada.
Why not just lift both pipe ends with deck davits on the side of the barge, remove pig receivers, measure and cut pipe ends and bevel, weld, NDT, corrosion coat without expensive and time consuming underwater operations.
When its very deep water and very large swells.
The pipe would buckle, twist and maybe break because the pipe would be to long when it is lowered back down on the subsea ocean floor.
It could be done like that but not exactly that way
They shoul use a lot of balloons to lift the pipe for kilometers at each end in order to reduce the inclination angle and avoid damaging it. But i believe for the repairs to happen the eu should join russia in a common effort which is something the US wouldn't want
The angle up to the barges would make the pipe to long when submerged again. Also you have to use air lift bags on huuge sections of pipe, would require many ships and barges and way to many rov/divers. Probably cheaper to use only one system in very confined area instead of making it into a huge lifting operation aswell (not the cheapest pipe your lifting either lol)
excellent,fabulous engineering....
When they beveled the upstream side, did that pipe have a 6" wall?
You got some fixing to do
Techno française les premières connexions de ce type en soudure hyperbare furent faites par Comex en mer du Nord dans les années 70 sur le pipe (32¨de mémoire ) d'évacuation vers l'Ecosse du gaz du champs norvégien de Frigg ..
Conclusion contrairement aux sottises déballées à longueur de journée par les médias :
les deux North Stream sont parfaitement réparables à condition de le vouloir ..
Someone is stealing material from someone to make videos like this one.
I sow the same video in other channel
what are those plr parts for?? in 1:18
Welding video of the pipe , look like a robot spool welder .
So, how long would say....3 sections, about 50' take to replace?
Repairs would take about 6 - 12 months.
The video was obviously knitted with a hot needle.
Good job!!
They never show that they actually bury all those pipelines. Jetting pipe .
really worth of watching, I really enjoyed. I call it FAST & FURIOUS IN SUBSEA.

Amazing
ป่าดงดิบ
Eqipment.
Now that the suisse co. has had to leave the job and cause a stoppage waiting for the russian boat that can do the job but is too far away (two months navigation) why doesn't Russia by the bloody boats from the suisse company ?
I want this job
show de bola!!!!!!!!!!!!
interesting
Look at what we humans can do.... I sure hope its safe.
it is okt first days of 2022
pipe damaged a few days ago
watching what advanced techology for handling this pipeline
it should be saved
sweden already sent submarine to observe the damage and gather possible evidence
its up germany and russia if they want to fix it
politicians should keep one thing is in sight, the interest of the population
ป้ัมน้ำ
Too easy...
It tuck decades to develop this .
Wenn nur diese schoißliche Hintergund"musik" nicht wäre!
USA la Russie reste une grande puissance mondiale
Amazing
