Improved Efficiency of Maintaining Facility Systems Serving the World’s Most Powerful Laser

Improved Efficiency of Maintaining Facility Systems Serving the World’s Most Powerful Laser

IMC-2016 Focused Forum - 32:41 
by David Hippie and Igor Maslennikov, Lawrence Livermore National Laboratory

The National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory (LLNL) is the world's most powerful laser and it is used for experiments at extreme pressures, temperature, and densities. This laser has 192 laser beams delivering 1.8 megajoules (500 terawatts) of energy onto targets for inertial confinement fusion research which supports national security, frontier science, and sustainable energy missions. Due to the highly stringent physics and operational requirements of the NIF, the supporting facility systems must be maintained and operated in a highly reliable manner. The NIF Facilities and Infrastructure Systems group is using various Uptime Elements™ to reduce unplanned repairs and improve the efficiency of maintenance activities. This presentation will provide specific examples of how we are using those Uptime Elements™.

Data Driven Reliability Strategies

IMC-2016 Reliability Engineering for Maintenance Learning Session - 45:33
by Alejandro Erives, 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 efficiency.

Maintenance & Reliability professionals have a wide array of tools at our disposal. From machinery required for maintenance to technology used for predictive maintenance the list is nearly endless. However, one often overlooked tool type is that of data analysis. Some of the tools available to a Maintenance & Reliability Engineer include Pareto analysis, life-data analysis (Weibull), failure trend analysis (Crow-AMSAA), and process data analysis (Process-Weibull).

Much as a good reliability program will use the right physical tools as part of a cohesive program, the data analysis tools can also be leveraged in a cohesive fashion to arrive at ever increasing reliability. This presentation describes one approach to utilize both production data and CMMS/Maintenance data to drive decisions related to reliability strategy development.

Analyzing Repairable System Failures Data

Analyzing Repairable System Failures Data

Many reliability engineers throughout history have had concerns with the reliability of the repairable system. Several researchers have presented a few calculation or estimation techniques to achieve repairable system reliability. This article explains the mean cumulative function (MCF) as a powerful and easy technique to estimate and monitor repairable system reliability.

Designing for Reliability

Designing for Reliability

IMC-2016 RAP Talk - 17:57
by Ramesh Gulati, Jacobs

According to Ramesh Gulati, designing for reliability (DfR) is the right approach to build reliability in assets. Not sure what DfR is? In this RAP Talk from IMC-2016, Gulati presents a comprehensive overview on the topic and how it will reduce operations & maintenance costs by a lot. Throughout the presentation, he stresses that this is a journey and requires a different kind of culture.

Why Organizations Leave Money on the Table

Why are organizations leaving money on the table by not investigating failures that cost them money? One would venture to say that all manufacturing companies have failures each year that cut into their profit. The prevailing question is: What do you do when that failure occurs? Do you simply fix the equipment, get back up and running, and return to whatever you were working on at the time? Or, do you stop what you are doing and diligently try to understand why the failure occurred and put measures in place to prevent recurrence? Is the culture at your facility one that seeks to understand why something failed or is it in a mode where you need to get back up and running as fast as possible? How about your commercial team and management external to your facility? Is there perceived pressure and a lack of understanding that have driven your organization to a place where failures are not fully understood?
