Valves, Pumps and Turbomachinery: Be cautious with systems that are not foolproof

Mishra, R., Indorama Eleme Petrochemicals and Fertilizers,

Mechanical systems, especially rotary equipment, are designed to support easy maintenance jobs with less complexity and low chances of incorrect installation.

Safety and environmental benefits of reliability engineering

Troyer, D., O'Malley, C., T. A. Cook

When you boil down the mission of reliability to its bare essence, the job is to deliver maximum operational availability for the least amount of money over the lifecycle of the asset.

Impact plant performance by improving the steam system

Walter, J. P., TLV Corp.

Petrochemical plants and refineries face production and profitability challenges on multiple fronts.

Reliability: Taking ownership of problems

Bloch, Heinz P., Hydrocarbon Processing Staff

Taking ownership of issues during a critical or troubling time is just as important as assuming responsibility during times of opportunity and benefit.

Reliability: Plan startups wisely and involve SMEs

Bloch, Heinz P., Hydrocarbon Processing Staff

DE, a retired former colleague of mine, recounted his experience as an expert witness for ABC in litigation against XYZ. (Note that I picked the letters A through M for the plaintiff’s side; N through Z are assigned to the defendants.)

Engineering Case Histories: Case 110: A checklist for vibration analysis

Sofronas, A., Consulting Engineer

Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.

Design of very-high-flow coefficient centrifugal compressor stages

Jariwala, V., Elliott Group

Centrifugal compressors are widely used in the oil and gas and petrochemical industries, with more than 15,000 operating in the U.S. alone.

Reveal the unmonitored risks in your rotating equipment: The effects of torsional vibration—Part 2

O’Connor, D., Gutierrez, J., Bently Nevada, a Baker Hughes Business

In recent case studies, unexpected and unmonitored torsional vibration resulted in sudden failures, costly downtime and potential safety hazards. Part 1 of this article, which appeared in the January issue of Hydrocarbon Processing, examined the origins of torsional vibration and case histories to drive an understanding of the unmonitored risk existing at many industrial sites.

Reveal the unmonitored risks in your rotating equipment—Part 1

O’Connor, D., Gutierrez, J., Bently Nevada, a Baker Hughes Business

On December 15, 2002, an anomalous event occurred in a steam turbine of Unit 2 at the South Texas Project Electric Generating Station, a pressurized water reactor (PWR) nuclear reactor near Bay City, Texas. The ensuing investigation concluded that a blade was ejected from a low-pressure stage, and detailed inspections revealed additional cracked blades in several stages.

Reliability: Things rarely heard at reliability conferences

Bloch, Heinz P., Hydrocarbon Processing Staff

We can only guess how many reliability conferences we have attended since accepting job offers in the refining or chemical processing industries. In my case, starting in 1965, it is somewhere between 60 and 80. If, in each of these conferences I listened to six presentations, the number of sessions attended is perhaps 400.
