to "maintain" a pipeline, you have to shut it down, and replace segments that are damaged. That means you have to undo welds that have been in place for years, and redo them with welds that may or may not be structurally sound immediately. All of the work of shutting down, and starting up again takes time, that is best spent sparingly, by stretching out the amount of time between shutdowns.

The New Orleans levee situation is completely different, in that case, you do work on the infrastructure while it is least needed to do its job, the dry season.
