I have driven along alot of the pipeline from Center to Valdez...It is an amazing feat of Human accomplishment and I doubt we could ever do it again...
It has outlived what “they” thought as well.
Oh and Alaskans hate to admit it but Texans built it. They just didn’t have the manpower back then.
My Sister has pictures of the pipe yard in Fairbanks it was HUGE.
Nor today for all the work needed just to maintain and do little projects. I am back to doing engineering for Alaskan North Slope work but I do it from Houston, Texas with a small team.
