Rapid Maintenance Response: When Plants Can’t Wait

By Adam Crosswell, Sulzer Chemtech |

Even with advanced predictive technologies, unplanned equipment failures can still occur. In these instances, as shown in this boiler example, rapid maintenance action is crucial to minimize downtime Maintenance activities generally fall into two categories — reactive and preventative. The first focuses on repairing an asset once a failure occurs, while the second aims to avoid asset failure and repairs by preventing issues before they happen. Such preventive measures are achieved by using predictive methods that leverage theoretical rate of failure and actual equipment performance. In an ideal world, rather than relying on reactive maintenance, a chemical processing plant will employ planned preventative activities to minimize downtime. However, in practice, unexpected equipment failures do happen, resulting in unplanned shutdowns and turnarounds. Businesses can still make the most of the circumstances by promptly adjusting their maintenance schedules to bring forward equipment-optimization projects. To succeed in this strategy, comprehensive, responsive maintenance practices are needed to support businesses. High-quality predictive maintenance models enable businesses to plan suitable maintenance schedules that maximize equipment…
