In this case, there was $150 million in rework. To repaint this plant would take a significant amount of time because of the intricate structures, rigging, and containments as well as the labor, which is a big factor, and the time that it would take. Many long shut downs would result in the loss of revenues. (is plant generates a total of $1 million a day in revenues when it's fully operational.) In a failure analysis, nobody w ins in the end: T he ow ner of a facility gets stuck w ith a substandard plant where the structural integrity is compro- mised due to the lack of management and poor coatings application techniques, and the contractor loses a substantial amount of money from not follow ing the specifications or the manufacturer's recommendations. Mitigating these ty pes of issues from the get-go is a much better solution when possible. CP Louis Sharp is a senior consu ltant for Energ y Project Resources.
