Status of Integrated Turnaround Maintenance

Turnaround Maintenance (TAM) in process industries is a very important event that requires a great deal of activities carried out within schedule, budget and quality. Furthermore, plants undergoing TAM are part of a supply chain partners that will be affected in one way or another by the TAM event. These partners include: upstream plants providing raw materials; downstream plants receiving plant products as raw material; and consumers of the final products. This global view of supply chain is rarely considered in TAM planning. The literature review indicated that the process industry does an excellent job with the internal (within the plant) planning and execution of TAM. However, it is not clear whether TAM is viewed in the wider supply chain context. Elements of supply chain includes: effective coordination, sharing experiences and learning from previous events. To assess the degree at which these elements are taken into consideration in TAM planning, the authors conducted a survey for industry worldwide to identify the status of shutdown/turnaround maintenance planning. The results of the survey indicated that there is a clear need to enhance the process of sharing best practices; learning from past events and developing key performance indicators that assess the impact of turnaround maintenance on plant performance. Such measures include impact of TAM on plant reliability, quality rates and productivity.
