Independent, vendor-neutral reliability and maintenance support for plants running DCS, PLC, and SCADA, backed by more than 25 years across Honeywell, Rockwell, Yokogawa, and Emerson.
Ongoing obsolescence and reliability roadmaps, ISA-18.2 alarm management, OT cyber-resilience, and independent service-agreement oversight, delivered as clear, ready-to-execute reports your team can follow. Planning a migration? Get an independent read before you sign.
You don't need another vendor telling you to rip and replace. You need an honest plan that fits your process, budget, and timeline.
End-of-life controllers, dwindling spares, and rising downtime risk on 20+ year-old systems that still run your plant.
Operators drowning in nuisance alarms, masking the events that actually matter and eroding safe, confident response.
Experienced techs retiring with undocumented logic in their heads, and new hires who've never seen a TDC3000.
Your capital projects may run through an EPC, but the day-to-day reliability of your control systems does not. The retainer puts an independent, vendor-neutral controls engineer on call each month to keep obsolescence, alarms, OT cyber-resilience, and vendor service agreements under control, without adding headcount.
For more than 25 years I designed and sold DCS and PLC service agreements from the vendor side. Now I use that inside knowledge to help plants structure agreements that cost less, cover more, and give you real leverage with the big vendors.
