I'm a power systems engineer in Pittsburgh working on substation upgrades. We piloted a quadruped robot with thermal and acoustic sensors for yard inspections. It did fine finding hot spots and noisy bushings, but the real win was catching a slow SF6 loss on a 115 kV breaker that was not wired into SCADA. The early read let us plan a service window instead of a forced outage. Lesson one: make robots look at what SCADA cannot see.Two surprises. First, connectivity. Yard WiFi was useless once...

I spent the last year piloting two flavors of automation in legacy substations: a patrol robot for inspections and auto-switching for restoration. Both reduced truck rolls, but the edge cases are where the real work is.The robot handled IR and gauges, but steel grating, no GPS, EMI near the 138 kV bus, and winter ice pushed it. Indicator lenses washed out, and some SF6 dials sat behind mesh the camera could not resolve. Cyber rules kept video off the control LAN, so we built a one-way drop for d...

At our Louisville plant we drum flammable solvent-borne adhesives and coatings. Last year we retrofitted two lines to closed-loop filling: bottom-entry lance, dry-break couplers, vapor return to a carbon bed, Coriolis mass flow, grounding interlocks, and LEL monitoring.Wins: odor complaints vanished, VOCs dropped, and we gained 8-10% throughput by cutting foam and false trips. The surprises were bottlenecks: pressure drop across the carbon bed crept up on long ketone runs, starving vapor return...

In our lab, a minor firmware update on a liquid handler and a new pipette tip lot looked harmless. Together they shifted dispense behavior just enough to skew bead cleanup efficiency on one assay. The fix was simple. Unwinding the downstream effects took two weeks of re-validations, retraining, and rescheduling. It reminded me that automation debt is as real as technical debt.What helps us: version-controlled methods and deck maps as code, a frozen set of validated consumables per workflow, and...

In our adhesives plant, most risk and rework still show up at the end of the line. Moving hydrocarbons from blend tanks into drums and totes used to be open and inconsistent. We switched to closed-loop bottom fill with Coriolis metering, a light nitrogen sweep, and an activated carbon vent. We also enforce bonding and verify continuity before every fill.Results were clear: tighter fill weights, fewer exposures, and lower VOCs. The new pinch point was what leaves with the truck. Bung torque scatt...

Spent my morning digging through HMI fault logs again. Another pump seal roasted because the unit started with the discharge closed and the seal flush blocked in. Well, there’s your problem. I keep hearing that we’ll train the operators and update the SOP. My answer is the same as always: just interlock it.We added simple permissives: no start unless discharge valve proof open, seal flush pressure proven, suction strainer DP below limit, and the VFD will not ramp if NPSHa proxy is low. Trips lat...

Lunch in the HMI fault log, nights with prep guides. Exams love perfect systems; plants give sticky valves, wet instrument air, and deadtime. The real answer starts with "well, there's your problem" and ends with whether the interlock actually catches it.Biggest ROI here: Vibration Cat I, proper LOTO refresh, and ISA 18.2 alarm rationalization. That cut nuisance alarms more than any feature. API 570 helped with corrosion and intervals. P.Eng ethics mattered, but not for taming a c...

Spent a chunk of last week chasing “mystery” underfills on our 1 - 5 L weight-fill line. Operators were bumping targets a few grams at a time, checkweigher rejects spiked, and we burned hours on rework. Turned out the product temp had slid 6 - 8°C overnight. Colder, thicker product changed the valve close behavior and scale filter response, so our warm-weather tuning was cutting off late and the dribble step wasn’t cleaning it up.Two simple changes helped more than any amount of knob‑twisting: w...

I spent an afternoon shadowing a bridge deck rehab crew along the Mississippi last week. As a manufacturing engineer, I was struck by how familiar the flow problems felt: material hunts, waiting on the crane, and long pauses around inspection hold points that ripple through the day.In our plant, we lean on kitting, color-coded consumables, and point-of-use standard work to reduce those hunts. I saw some of that on site, but binders stayed in the trailer and crews relied on memory and radio calls...

An alarm is not a control. If a piece of equipment can eat itself in under a minute, no operator is going to save it with an acknowledge button. We designed it that way, then we blame ops for “not reacting.” That’s on us.Example: a transfer pump kept losing bearings every few weeks. Suction strainer blinded, HMI threw low suction and high vibration. Night shift throttled a valve and hoped. Pump still cavitated to death. Well, there’s your problem. We added a DP across the strainer, blocked start...
