Leveraging Parallel Work Identification Strategies to Achieve Rapid Results

Work Identification and Asset Reliability

Most maintenance professionals would agree that applying a structured work identification methodology (can be taxing on an organization’s resources in today’s business environment which begs the question - What else is available to rapidly develop or validate maintenance programs for my asset base without jeopardizing the safety, environment, quality and production integrity of my plant?

Leveraging PAS 55 Within National Grid

National Grid's journey with implementing PAS 55 Development of a cross business asset management initiative Using PAS 55 to develop a common language across different geographies and networks Using the platform created by PAS 55 to share business practices and develop common ways of working Sharing asset management practices with businesses outside National Grid using PAS 55.

Life Cycle Cost

Life cycle cost (LCC) are all costs associated with the acquisition and ownership of a system over its full life. The usual figure of merit is net present value (NPV). Projects are considered most favorable for large positive NPVs. However for many cost individual cases, decisions are made for the least negative NPVs. In all cases, the default position for accounting is to know the NPV for making no change and this is usually the last alternative for most people associated with change.

Life Units

A measure of use duration applicable to an item. For example, the life units may be starts-stops, run hours, hot-cold cycles, distances traveled, emergency starts or starts, shelf life, and other measurements which motivate failures.

Linking Lean Manufacturing and Reliability

by Andy Page, GPAllied

The concepts contained within Lean Manufacturing are not limited merely to production systems. These concepts translate directly into the world of maintenance and reliability.

 

Living Reliability: Principles and Learning

Abstract: The key to Reliability is more a mind-set than the hard technologies that exist on the market today. When we travel to conferences and shows for Reliability we are inundated with vendors that supply technologies to execute Reliability strategies. Such technologies are integral to the ultimate success of a Reliability endeavor. However, if the organization does not have the foresight and vision needed at the executive level to set the stage, then the principles of Reliability will likely not take hold enough to change the culture. Does your organization practice the principle of Reliability?

Load-Strength Interactions

For reliability successes, loads must always be less than strengths. When loads are greater than strengths, failures occur. The issue is determining the probability of load-strength interference which is a joint probability of when loads exceed strengths. The loads should include expected conditions plus the foolishness of people to violate rules and overload equipment, plus the vagaries of Mother Nature to impose unexpected static and dynamic loads from hurricanes, tornadoes, earth quakes, wild fires, and so forth.

Lognormal

Lognormal distributions are continuous life functions that have long tails to the right (display positive skewness) in time or usage. A lognormal distribution plotted on semi-log papers would appear as a normal curve.

Long Beach Transit Case Study

ABOUT LONG BEACH TRANSIT

Each year, more than 29 million people in southern California travel on buses operated by Long Beach Transit. The transit company provides fixed and flexible bus services in Long Beach, Lakewood and Signal Hill, as well as portions of Artesia, Bellflower, Carson, Cerritos, Compton, Hawaiian Gardens, Norwalk, Paramount and Seal Beach.

Looking Back to See the Future

I recall a pump failure that occurred in the early years of my career. I was part of the mechanical equipment group in a large refinery. We received a call telling us that the transfer pump next to one of the tanks in the tank farm was not working and they needed it fixed immediately. For some reason, a mechanical engineer was the first person sent out to determine what was wrong so I got to see things from a different perspective.

Lubrication Excellence at the San Onofre Nuclear Generating Station

At the San Onofre Nuclear Generating Station (SONGS), the oil sampling and analysis program has evolved since its inception during the plants start-up in the early 80's. The program has used on-going aggressive improvement plans and program audits, while implementing many of industry's best practices. As a result, progress reports show low equipment failures, increased awareness of Pro-active Maintenance initiatives, and station support from the craft level to executive level management.

Machine Train Alignment

by Damian Josefsberg

Machine train alignment doesn't have to be a complicated, mind boggling task. There is a basic step by step procedure to follow which will allow you to maximize all of the benefits of aligning a machine train. When you follow this procedure and adhere to its principles, you will find that machine train alignment can often be easier to accomplish than a one coupling "vanilla" alignment.

Maintainability

The measure of the ability of an item to be retained in or restored to specified condition when maintenance is performed by personnel having specified skill levels, using prescribed procedures and resources.

Maintaining The Long Term Reliability of Critical Power Systems in Water Processing Plants

By Reza Tajali
Schneider Electric

The critical applications in water and wastewater processing plants require uninterruptible power of a high quality. The most basic of these systems utilize automatic throw-over switches. The most advanced systems include UPS (Uninterruptible Power Supply) and generator equipment that maintain the continuity of power without one cycle of interruption.
