Completing the Curve

Completing the Curve

Back in the June/July 2006 issue of Uptime, I authored an article entitled Expanding the Curve detailing why the traditional P-F curve was incomplete. While it was expected that the article might elicit both positive and negative comments, it came as a surprise how strong some of those opinions were.

From a Different Angle: A Perspective - Defects, P-F and the Rest of the Story

From a Different Angle: A Perspective - Defects, P-F and the Rest of the Story

Think about all the initiator causes of failure that are not really related to maintenance. Initiator causes are those events, possibly microscopic, that initiate decay shown by the P-F curve. Examples of initiator causes might include heat, dirt, or overloading.

Strengthening the Fundamentals: CNS Y-12’s Journey to Asset Reliability Excellence

Strengthening the Fundamentals: CNS Y-12’s Journey to Asset Reliability Excellence

IMC-2017 Learning Session - 32:02
by Paul Durko, Consolidated Nuclear Security (CNS) Y-12, & Jason Ballentine, ARMS Reliability

Many organizations are faced with trying to develop, document, and execute optimized maintenance strategies for their assets with limited resources. But imagine if this challenge was compounded by constant turnover of leadership, aged assets, and one other small thing – the maintenance budget had to be signed off by the President of the United States.

CNS Y-12, a government entity that maintains the U.S. nuclear stockpile, has certainly had its challenges breaking free from reactive maintenance mode. When it came time to commence a maintenance strategy optimization project it was important for them to do it as effectively and efficiently as possible.

This presentation covers the approach that CNS Y-12 chose to follow to review their strategy, identify gaps, and develop optimized maintenance strategies that can be immediately implemented and easily deployed to their CMMS for execution.

CNS Y-12 is now shifting from a reactive, as-needed maintenance plan to a proactive plan with strategies that will be applicable to all existing and future managed facilities. They can now meet their goal of controlling their assets verses the assets controlling their behavior. Other results include increased safety, decrease risk of unplanned events, efficiency gains, and an improvement in KPIs around maintenance and reliability metrics. CNS Y-12 will also be able to create a maintenance budget that is justified with a sound reliability foundation to present to the United States Government and show the risk/benefit of any additional funding.

Seeking the P-F Interval

Seeking the P-F Interval

IMC-2017 Learning Session - 40:25
by Alejandro Erives & Jason Zielinski, Stepan Company

Stepan is a chemical company producing specialty and intermediate chemicals such as surfactants, polymers, and other specialty products. A broad description of our goals include improving asset utilization, reducing cost, and improving efficiencies.

The P-F Interval is a widely known term / concept in maintenance and reliability circles. The time it takes for a defect to grow from a detectable size to a functional failure (i.e. “the P-F Interval”) is critical in determining condition based monitoring frequencies. Additionally, an understanding of the P-F interval is helpful in determining maintenance planning / scheduling priorities for corrective actions, once a defect is discovered.

Except for special studies or applications, the P-F interval is widely seen as highly subjective. However, through careful analysis of several years of condition monitoring data we have been able to quantify this time interval in our facility. We will show that being armed with a better understanding of the P-F interval at our facility can improve maintenance and planning efficiencies, especially as they relate to work generated from our predictive maintenance (PdM) programs.

Maintenance as a Profit Center

Maintenance as a Profit Center

Times and thinking in the Industrial World have changed dramatically in the past three decades. Traditions that have literally been sacred cows in those post WWII years have been forgotten; witness that the “Greatest Generation” is almost a “Vanished Generation”. Technically speaking, some of this has been good and necessary – some maybe not.

Some Plain Talk About Nuts and Bolts: Part 1 of 2

When you look over the list of projects you’ve worked on in the last 20 or so years, it’s amazing how many involve fastener problems. Some are relatively easy to solve, especially where careless practices have resulted in fatigue failures. Other problems are much more sophisticated, such as aluminum rivets clamping aluminum sheet metal that failed from galvanic corrosion! In Part 1 of this series, a Q&A addresses some of the important points connected with common bolting practices.

A Strategic Approach to Optimizing Proactive Maintenance Using Classical RCM

A Strategic Approach to Optimizing Proactive Maintenance Using Classical RCM

The RELIABILITY Conference Learning Session 37:29
by Neil Meyer and Clint Shima, Central Contra Costa Sanitary District

This session relates a SUCCESS story at the Central Contra Costa Sanitary District (Central San) on the use of Classical RCM to optimize our Treatment Plant Proactive Maintenance. This plant, originally created in 1946, today services 500,000 customers and treats 55 million gallons of wastewater daily with a 24/7 operation. Our mission to protect public health and promote environmental stewardship is supported by efforts to continuously improve overall maintenance effectiveness and asset reliability over the life cycle of the asset. The Classical RCM process is a natural path to pursue in this regard because it initially uses the 80/20 rule to identify the "bad actor" critical systems. It then systematically defines their system functions and the specific equipment failure modes that require proactive PM tasks to avoid high consequence safety, environmental and outage functional failure issues. The project discussed herein is part of an asset management program at Central San that focuses on establishing a framework for Central San to improve maintenance efficiency and functional reliability of assets that is a repeatable program with documented processes and procedures. How this is achieved is described in detail.

Cost Reductions Without Losses to Equipment Effectiveness and Asset Integrity

Cost Reductions Without Losses to Equipment Effectiveness and Asset Integrity

Maintenance and reliability teams, programs and practices seem to be a constant target for cost reductions, but this brings up an important question: How can it be accomplished without losses to equipment effectiveness and asset integrity?

When companies implement overarching programs to reduce equipment failure, it isn’t always apparent where the problems and root causes exist because the programs often attempt to address everything at once. Some immediate returns and benefits are realized, however, these programs often do much more than is actually required. An example includes following the original equipment manufacturer’s guidelines without taking into account or adjusting for site specifications and equipment layouts.

Reliability Centered Maintenance (RCM)-Driven Asset Management for Major Capital Projects

Reliability Centered Maintenance (RCM)-Driven Asset Management for Major Capital Projects

The RELIABILITY Conference Case Study - 43:16 
by Walter Sanford, PinnacleART

You spent 10 billion USD conceiving, designing, constructing, and commissioning a major capital project for an offshore production asset. Now, how are you going to manage it? A comprehensive, proactive, risk-based maintenance plan is an integral part of your asset management program. Another essential component is a risk-based operational spare parts strategy – identification of the parts needed to complete proactive and corrective maintenance tasks for operating equipment, and how these parts will be made available when needed. This case study reviews the methodology used and the results achieved for using RCM to drive the comprehensive Risk Management strategy for a major capital project. Development included critical Asset Management elements, such as the Asset Hierarchy, Risk Based Maintenance program, Operator Driven Reliability, Risk Based Spare Parts Strategy, and all associated procedures and plans, fully populated in the CMMS and other management systems. The results demonstrated significant benefits over traditional approaches. For example, performing the detailed spare parts analysis and making risk-based decisions for stocking quantities resulted in a cost savings of over 10 million USD in reduced part stocking requirements, compared to following the vendor recommendations.
