Industries
If you run to these standards, we cover you.
FoxIQ works across the whole control system: the alarms operators see, the logic behind them, the safety systems that trip the plant, and the documents that are supposed to describe all of it. Our work is built on the standards themselves, so it applies to every industry that operates by them.
Refining and petrochemical
Decades of modifications, alarms added and never removed, and logic that no longer matches its documents.
Alarm management
PSM-grade KPI audit, flood cascade maps and suppression rules ready for MOC, with SIS trips correlated to their precursor alarms.
Control and safety logic
Interlocks verified against the cause-and-effect matrix, and the configured controller compared with the narratives it is supposed to follow.
Field and documentation
Narratives rebuilt from the running code, loop folders generated from the tag register, and turnaround commissioning support.
Offshore production
Small crews, slugging and flow instability, and safety systems that must work first time with no one on hand to diagnose.
Alarm management
Oscillating tags identified as one phenomenon with one cause, frozen and failed instruments surfaced. Proven on real offshore well data.
Control and safety logic
Well and topsides shutdown logic checked against the cause-and-effect matrix, including voting and bypass behaviour.
Field and documentation
Engineers who work offshore commissioning rotations, and documentation built to hand over to the platform crew.
LNG and gas processing
Short time to consequence, tightly coupled trains, and startup behaviour nothing like steady state.
Alarm management
Flood analysis under short response windows, with KPIs split by startup, steady state and shutdown.
Control and safety logic
Trip sequences verified scan by scan, so rung order cannot defeat the shutdown design.
Field and documentation
Commissioning support through startup, when alarm and trip behaviour is least understood.
Pipeline SCADA
Controllers watching long lines across many stations, under federal control-room management rules.
Alarm management
API RP 1167 KPIs per controller and console workload modelling, documented for control-room management review.
Control and safety logic
Station PLC logic reviewed for permissives and shutdowns that do not match the documented design.
Field and documentation
Station documentation brought back in line with what is actually installed.
Power generation
Unit trips and start-up sequences flood operators at exactly the wrong moment.
Alarm management
Trip and start-up alarm sequence audits, with precursor alarms ranked by how reliably they come before a trip.
Control and safety logic
Balance-of-plant PLC logic reviewed and standardized, with interlocks verified against the design.
Field and documentation
Control narratives and loop documentation rebuilt for outages and upgrades.
Pharmaceutical and biotech
Batch phases change alarm behaviour, and every analysis has to survive a data-integrity audit.
Alarm management
Phase-aware batch KPIs with a hashed analysis audit trail.
Control and safety logic
Configured-versus-documented comparison, so validated documents match the code that actually runs.
Field and documentation
Documentation packages structured for validation review.
Datacenters and critical facilities
Building and electrical systems that alarm on everything, with critical events buried among informational ones.
Alarm management
BMS and EPMS rationalization and cascade analysis of electrical and cooling events.
Control and safety logic
Transfer, load-shed and cooling control logic reviewed against the sequence of operations.
Field and documentation
Sequence-of-operations documents rebuilt from the code, and commissioning support.

One team across the whole control system
Most firms cover one layer and hand you to someone else for the next. We cover all five, and we check each one against the others.
Alarm management

- Floods traced to their first alarm
- Suppression rules in your DCS’s import format
- PID retuning for chattering loops
- Improvement verified after implementation
Control logic
- Line-by-line code review
- Configured versus documented
- Standardization onto documented libraries
- Logic minimized and proven equivalent
Cause and effect
- Interlocks checked against the matrix
- Masked causes and redundant cells
- Trips that a start command can override
- Scan-by-scan correctness
Safety instrumented systems
- SIS logic checked against the C&E and safety requirements
- Voting architectures reviewed for common-cause failure

Engineering you can hold to account
What you get when the people doing the analysis have also stood in front of the panel.
We commission what we review
Our engineers commission instrumentation, control and safety systems, offshore and onshore. The review is written by people who know how the plant behaves when it starts up.
Verified, not sampled
Interlocks and logic are checked mathematically against the design, not spot-checked on a few rungs.
Clause by clause
Every finding cites the standard it answers to, so your reviewers can check the reasoning themselves.
Analysis to the loop check
When a fix needs hands on hardware, Red Fox Automation, our field services arm, carries it through. No handoff to a stranger.
Same-day answers
Based in Houston. An engineer replies the same day, seven days a week, on your time zone.
Your data stays controlled
We work from exports through our client files area, never connected to your systems, with retention you set.
