Tie-ins into the existing Ras Tanura network are the textbook arc blow scenario: the line in the ground has been under cathodic protection for years and carries a residual field that deflects the arc. If welders are struggling at the tie-in and not on the new pipe, the pipe is magnetised — and that is a ten-minute fix, not a welder problem.
Pipeline work in Ras Tanura
The refinery and the Juaymah export terminal sit on a dense gas and crude transmission network. Replacement and refurbishment of existing transmission lines is ongoing work rather than an occasional project.
Transmission line replacement and refurbishment on the gas and crude network feeding the refinery and the Juaymah export terminal, plus scraper trap and valve station work.
A mix of planned replacement programmes and unplanned integrity work. Both are permit-controlled and both move faster than a general construction site.

Why internal beats external on large diameter
An external clamp pulls the pipe ends together from the outside, which corrects ovality only where the clamp shoes sit and leaves the root free to drift between them. On large-diameter thin-wall pipe that drift becomes hi-lo, and hi-lo becomes a repair. An internal clamp expands from inside against the full circumference, so it rounds the pipe and holds the root gap uniformly all the way round, and the welder can complete the full root without stopping to reposition. On a mainline spread that is the difference between a weld rate you planned for and one you did not.
