I don't think people realize how hard it will be to repair the Nordstream pipeline

Here is a video of what it took to construct a natural gas pipeline from Norway to Great Britain. Watch this and realize how fuked repairing the Nordstream pipeline will be.

I know a few other brahs in here who work in O&G and likely have an idea what would be involved, I've personally been on several projects doing crazy chit with spools as large as 48" and was working on Keystone XL on the Canadian side before the project was axed

The question is why it would be repaired

I worked at Nordstrom for a couple years way back when, it was easier being a stocker than on the floor with sales. But still it wasn't that difficult OP, you must be dumb

I do wonder if it even can be repaired.

If you watch the video in OP, constructing the pipeline was just barely possible when they were doing everything above water and then slowly laying the pipes in a controlled manner down to the sea bottom. Going down and trying to repair sections is a whole different ball game.

It's pretty simple really. Just drain the ocean around it, repair it, profit?

It's definitely possible to repair, although Katya brought up some comments in another thread about seawater infiltration compromising the integrity of the pipe wall if left exposed for too long and that's likely very valid


I've been on projects where we even cut into pressurized lines for repairs in operating plants, although it was above ground. We used liquid nitrogen to freeze the contents on both ends of the section to be repaired before cutting in and installing the new chunk.


There are companies who specialize in doing such repairs

All that saltwater intrusion and subsequent corrosion would make it nearly impossible to repair. But I'm not a materials engineer so who knows...

Think it might last longer than you would think as the steel is treated. Someone correct me if I am wrong. Wouldn't surprise me if it can go a few months with relatively no issues.

However, the winter season is coming which means bad weather, which makes repairs more difficult.

I'm a natural gas pipeline welder. Problems I see, getting the water out of the line. Are we talking yards or miles of pipeline that is full ? If they can keep a positive pressue in the line to prevent water from getting in and clamp the leak they well be ahead of the game. If the line goes to zero pressure and fills up, big trouble

Doesn't the pressure only come from one direction? Considering explosives were likely used and probably destroyed at least 5-25 meters of pipeline I would guess the side that is cut off from the Nat Gas source would essentially all be full of water. So miles.

From what I have read, it may not be repairable if salt water has been inside the pipe long enough to start corrosion.

The pressue is continuous from one side. If it's a full opening break then one side will have pressue till they shut it down. If it's a hole in the pipe then pressue from one end or both ends doesn't really matter. Now that I think about it, it's probably a full opening on both ends. It's a bad situation. One side will go dead once the pressure bleeds out then fill with water. It's called " pipeline liquids " in the industry. Incredibly hard to get out. Look up " smart pigs " . It's how they will push the water out. They will have internal corrosion issues in the future. If it's hundreds of miles of straight pipe with no one way check valves to prevent this very issue, there is big problems. Also I know there is underwater welding , but that's more structural. You want to weld a joint on a vessel carring 3000 psi ? That's a little different then welding a beam to a beam on a oil rig. The pipe is over 1 inc thick

Do you know how long sections can go without repair before the seawater corrosion completely destroys the pipe? I've heard the steel was treated (not sure if just outside or inside as well) so there might be some time before it becomes unsalvageable.

That pipeline was designed to last probably 100 years. No corrosion it essentially last forever. Now with sea water in it which contains oxygen now you have rust. No oxygen no rust. Now that oxidation has set it in, can they get every drop of water out ? Will they line it with a coating? For a brand new pipeline its major setback. Also if you get a slug of water to go down stream and get in equipment designed to handle a compressible gas and not a non compressible liquid, stuff breaks. Sea water is highly corrosive. Time wise it's not so much that the pipe is bad in a month, it's more the pipe is bad in 20 years when we needed it to go 100 years to be profitable

Natural gas pipelijes don't like shut off valves. Gas air mixture is dangerous. They want to keep the pipeline full of gas.

4 to 14 percent gas to air mixture is when ignition happens. If you fill a room with 100 percent gas and light a match it won't go boom . You need oxygen.

I'd be very surprised if there was no shut off valves on the line.

L450 pipe will withstand the salt water for a little while before corrosion is the main concern.
