>> Technology base for condition management Figure 3. Plant- and corporate-level technologies need to come together effectively. the largest portion of the gains come from properly managing the “operate and maintain” stages of the lifecycle. It’s precisely at thoses stages where condition management is an essential enabler of improvements. The ARC lifecycle model, (Figure 2) illustrates the proper relationship between plant asset man- SERFILCO® SERFILCO® SERFILCO ® Centrifugal ‘3x2’ Pumps agement (PAM) and an asset lifecycle management scheme. Corporate knowledge. Does the company have a knowledge management process or tools? What’s the current state of the work force? Is a retirement bubble coming up that necessitates immediate action? Does the company really know where the necessary knowledge resides? Skill base. Does the rm have the essential expertise in areas such as reliability-centered or condition-based maintenance, optimization, advanced process control (APC), and condition monitoring and analysis? Technology base. To fully achieve the promise of condition management, a wide range of technologies both in the plant and at the corporate level need to come together (Figure 2). So, engineers, planners and managers need to work together and ask themselves a series of technology questions that focus on ve key areas. 1. The state of the core automation systems. Is the distributed control system current? Is the plant using a digital eldbus with intelligent devices, traditional 4–20-mA analog or both? This will impact what data are available and how to access them. It’s important to understand that the plant doesn’t need to be “state of the art.” Many new analytic tools can infer conditions from the simple data points that are being collected as part of the control strategy. It’s also crucial not to confuse alarm management with condition management. Alarm management plays a critical role in dealing with the huge number of discrete input/output points that are part of the control strategy, working in real time at a discrete level. Condition management complements alarm management by performing the advanced analytics that warn of a developing issue long before it becomes a process or system alarm or alarm storm. 2.
