How long is it going to take to repair this?
Nobody knows for sure yet. Channel 2 ran some numberrs tonight
They are looking at initially 16 miles of pipe that will need to be replaced. I don't know exactly what the diameter is, but most of that stuff they use is arctic grade steel and that is a specialty item, like avgas. So any they can't find "off the shelf" will have to be made, and I can tell you that lead times from mills for metal products of any type have been getting much longer over the past two years.
Then you have to weld the joints together, they estimated it would take two guys half a day to complete a weld (I think that is a hint on the pipe diameter). There would need to be a weld every 40 or 80 feet. You do the math on 16 miles.
There isn't much choice about replace vs. patching. They found 16 "annomlies" in that pipe and according to the news when the story first broke there where some places where 70% of the original pipe thickness is gone. Again those numbers are the ones I remember on the nightly news the day the story broke.
Edit: Forgot the 1000 odd guys they are going to have to hire, train, feed,house, and the equipment to move up there. Most of the speciality gear and tradesmen are in the gulf right now making money repairing Katrina damage.
