A turnaround is a scheduled event wherein an entire process unit in a refinery or manufacturing site is taken offline for an extended period of time to perform maintenance, modifications, inspections, catalyst regeneration or changeouts, as well as any related projects (Figure 1). Turnarounds provide an important window of opportunity for essential maintenance tasks and allow for safe and efficient servicing or replacement of process equipment. If done correctly, turnarounds can potentially lead to huge gains in the facility’s productivity and output. However, turnarounds are also extremely costly events in terms of direct costs for labor, tools, heavy equipment and materials used to execute these projects. If the budget balloons or the timeline unexpectedly expands, it can have disastrous effects on a company’s bottom line. FIGURE 1. Turnarounds are a challenging —…
