labour time book for refinery turn around maintenance

Turn arounds are generally pretty time constrained as an operation or many may be shut seriously impacting the revenues. Therefore the time things take have to be well thought out and planned accordingly as the plant with have to adjust inflows and outflow supply chains etc. leading up to and after the shut down. Will a company keep a log of past shut downs, maybe. But turn arounds are dependant on the plant and the area of a plant that is being shut down, therefore finding a book for specific activities probably will not exist. But there are plenty of rules-of-thumb which might be pretty close to the mark.
