I have been working for some time to offer this online course for Noria and faced challenges that I would explain in this article. https://turbineoilreliability.com/2026/05/13/%f0%9f%9a%80-machinery-lubrication-level-i-online-training-course/ Why Noria Lubrication Training Delivered by Khash Is Different from Typical ICML Exam Preparation In the lubrication training market, many providers now offer ICML exam preparation. Some are priced attractively,Continue reading "Why Noria Lubrication Training Delivered by Khash Is Different from Typical ICML Exam Preparation"

Lubrication-Related Inspections in Turbomachinery 1. Introduction Lubrication is one of the most critical support systems in turbomachinery. In turbines, compressors, expanders, pumps, gearboxes, and high-speed auxiliary drives, the lubricant is not only reducing friction. It is also removing heat, carrying away wear debris, protecting surfaces from corrosion, supporting hydrodynamic oil films, supplying control-oil circuits, and,Continue reading "Lubrication-Related Inspections in Turbomachinery"

Khash TNA (Training Need Analysis) How strong is your team’s lubrication knowledge? I am inviting maintenance, reliability, lubrication, and condition monitoring teams to participate in the Khash TNA – Training Need Analysis, a structured knowledge assessment designed around lubrication fundamentals and MLA-level competency areas. The assessment includes 100 multiple-choice questions covering lubrication knowledge across: MLA I • MLAContinue reading "Khash TNA (Training Need Analysis)"

100 Questions to Ask: How Khash Understands Whether a Lubrication Specialist Has Practical Experience A lubrication specialist can sound very knowledgeable in an interview. Many candidates can define viscosity, additives, ISO cleanliness, grease consistency, or oil analysis. The real challenge is different: has the person actually worked with machines, lubricants, samples, contamination, grease guns, failed bearings,Continue reading "100 Questions to Ask: How Khash Understands Whether a Lubrication Specialist Has Practical Experience"

Why Add OMX When You Are Already MLE, CLS, MLA III, MLT II, VIM, and VPR Certified? Because Oil Analysis Without Expert Interpretation Is Just Expensive Color Printing A friend recently looked at Khashayar Hajiahmad’s certification list and asked a very reasonable question: “Khash, why are you trying to add OMX to your certifications? YouContinue reading "Why Add OMX When You Are Already MLE, CLS, MLA III, MLT II, VIM, and VPR Certified?"

LNG Plant Turbomachinery: Turbine Oil in Refrigeration Compressor Trains Highly technical reliability article for LNG liquefaction, refrigeration compressors, turbine drivers, oil analysis, filtration, and varnish control LNG plants are among the most demanding turbomachinery environments in the oil and gas industry. The liquefaction section depends on very large refrigeration compressor trains, high-power turbine or motorContinue reading "LNG Plant Turbomachinery: Turbine Oil in Refrigeration Compressor Trains"

Turbine Oil Challenges in Offshore Platforms and FPSOs A technical reliability article for oil & gas turbomachinery, power generation, and utility systems Offshore platforms and FPSOs operate in one of the most severe environments for turbine oil systems. A turbine oil that performs well in a clean, land-based refinery may face a completely different dutyContinue reading "Turbine Oil Challenges in Offshore Platforms and FPSOs"

Khash Field Experience in Ammonia, Urea, Utility, and Power-Generation Turbomachinery How oil analysis, filtration, dehydration, and varnish control protect critical rotating assets in Middle East process plants Across Middle East ammonia, urea, petrochemical, oil and gas, and power-generation facilities, Khash’s field experience has been centered on one highly practical reliability principle: critical turbomachinery is only asContinue reading "Khash Field Experience in Ammonia, Urea, Utility, and Power-Generation Turbomachinery"

Dissolved Metals vs Solid Particles in Oil Analysis When an oil report shows metals by elemental analysis and also shows a particle count, it is easy to think both tests are measuring the same thing. They are not. They overlap only partly. The simplest clarification is this: Elemental analysis answers: “Which chemical elements are present in the oil sample,Continue reading "Dissolved Metals vs Solid Particles in Oil Analysis"

Turboexpanders and Oil Varnishing: Why a Small Bearing Can Decide the Reliability of a Petrochemical Plant The bearing shown in your photo appears to be a small turboexpander bearing pad or shoe. The dark brown-to-black deposit on the working surface is consistent with severe oil-derived deposit formation: varnish, lacquer, thermal coking, or a combination ofContinue reading "Turboexpanders and Oil Varnishing: Why a Small Bearing Can Decide the Reliability of a Petrochemical Plant"
