Whats Weighing Down Your Pipeline Integrity Program?

So I’m sitting at my desk, trying to figure out how to make Excel do what I want it to, but all I am getting is “#VALUE!.” What does that even mean? Then my phone rings. The call is from our construction supervisor, who is overseeing the repair digs on a recently completed 200-mile coating survey on a buried pipeline. He asks, can our survey method identify anomalies under concrete coating or swamp weights?
