The industry has gone to a "data based" turn-around work scope.It’s more likely a consequence of decades of running California’s refineries at over a hundred percent capacity. That was accomplished by cutting maintenance intervals.
The problem is that an exchanger might be clean (as per the overall performance) at the end of a turnaround. But fouling is not linear and it may take only a year to hit the steep part of the hocky stick curve.
The industry is finding out that all the "savings" from this process is being eaten up by intermittent unscheduled shutdowns.
