Applying Ram Analysis To Support Maintenance Excellence Practices Aimed At Optimizing Turnaround Scope

by Regan Pooran, Phoenix Engineered Solutions Inc.

Application of Reliability Availability Maintainability (RAM) analysis to support elimination of unjustified turnaround scope (by 15-30%), the mitigation of unacceptable business and HSE risks, and the understanding of the diminishing return of risk reduction to enable informed decisions.

Learning takeaways:

1. How an equipment production and cost criticality list (produced from the RAM model) can be utilized to identify turnaround scope reduction opportunities.
2. How to assess scope reduction opportunities in a simulation environment (first and foremost), prior to directly risking implementing them in the plant, significantly minimizes the downside risk of implementing opportunities that produce diminishing or negative returns.
3. How the RAM modeling in sync with lifecycle cost analysis can be used to assess the cost-benefit of deleting the maintenance work during turnarounds, executing the mitigation strategies, moving the maintenance work to post or pre-turnaround, and reducing the scope of work.
