I’m not writing your certification/PHA, stamping your drawings, or performing your inspection. I’m solving your problems. The HOW is what I care about.
I don’t assume you have to disassemble the entire engine in order to fix an oil consumption problem. I find the root cause and work from there.
I don’t believe you can replace one pump in the system without affecting the rest of the hydraulic circuit. I reimagine the system with the new component.
What Derek works on
01
Rotating and reciprocating machinery — engines, pumps, compressors, blowers — from root cause to rebuild.
02
Power, controls, and instrumentation that keep machines protected and observable.
03
How the pieces interact — process, machine, controls, and the people running them.
04
Practical help turning existing PHA recommendations into equipment and maintenance work.
Selected work
01 · Completed system
02 · CAD & mechanical design
03 · Electrical / electronic systems
Problems I solve
01
Check the operating conditions, flow path, and measurements before deciding what needs replacing.
02
Look at the duty, cooling, lubrication, and gas conditions together — not just the temperature trip.
03
Use vibration and operating data to investigate the mechanism, then check the proposed correction.
04
Review combustion conditions and operating history. Document the findings and the reasoning behind any changes.
Who is behind the work
From manure weirs to reusable rocket engines, Derek has spent his time in the design, manufacturing, and operability of rotating equipment and fluid systems.
Have a machine or a PHA recommendation to discuss?
