Walt Boyes, Editor in ChiefIF YOU'RE one of the thousands of process automation professionals around the world burdened with an older, maybe even antiquated plantâlisten up. Weâre not just talking to you if you live in the U.S., the rest of North America, or Europe, either. There are older, out of date plants everywhere. They exist in Japan, India, and China, too. So in this article, we are talking to YOU!
Whatâs Asset Management?
You may be confused when people use the term, âasset management.â It isnât an accident. Itâs a buzzword like âsynergyâ or âintegrated.â Some vendors use it to mean an operations and maintenance function, like predictive maintenance. Others use it to mean process optimization, using a plantâs control system and field devices. The term is in serious danger of becoming whatever the vendor wants it to mean, when heâs explaining to you why you can no longer get along without it. However, both asset management and asset optimization can make you a lot of money, if you play your cards right. In the next few pages, weâll show you how to draw a full house with asset management.
The simplest way to look at this is as a series of steps to improving your plantâs availability (what we used to call âuptimeâ). Even though itâs clear that itâs a very costly practice, many plants still operate on reactive maintenanceâwhen itâs broken, then they fix it. The reason this is so costly is clear from the âafter incident reportsâ weâve all seen. The failure of a $3,000 level sensor shuts down an entire batch reactor train, costing the company $50,000 per hour in lost production, for days, while the device is repaired or a new one is procured.
This has led companies to try predicting where problems will occur, based on history, and allows failure-prone devices (valve, motor, sensor, controller, etc.) to be replaced during scheduled maintenance shutdowns so they donât die during a production run.
