Built by a 10+ year gas plant operator. Professional DCS-style reference for the Stabilizer, the board every operator masters first.
Track revenue, penalties, and net profit hour by hour. Hit your shift targets the way you would in the field.
Respond to upsets, weather changes, pig arrivals, and equipment failures the way they happen on shift.
Full process flow diagrams with working valves, controllers, and instrumentation. ISA-101 color discipline throughout.
Step-by-step procedure notes and P&ID study with overlays. No failure state. Use it like a living operator handbook before you sit at the real board.
Full shift simulation with Plant Rounds (your personal baselines), pop-out trends, realistic pig surges and equipment faults. Reference tool + zero-risk AOC rehearsal.
The essential first board every operator masters. Use the P&ID, faceplates, trends, and Plant Rounds as reference during real shifts. Rehearse pig arrivals and faults with zero risk.
Real operations reference. Pig receiver, inlet sep, hot oil, reboiler, tower, compression, tanks, RVP, truck loading.
Ops reference tool. Use the P&ID and faceplates on shift. Rehearse events here first.
Not a game. A high-fidelity reference and practice system that rolls AOC rehearsal, on-shift reference, and audit-ready records into one place, at a fraction of what a traditional OTS stack costs.
New operators build real pattern recognition on the exact board they will run before they touch a live DCS. Rehearse pig surges, hot-oil cascades, compressor trips, and off-spec excursions with zero risk to production or safety. Experienced operators get refreshers on rare high-consequence events without waiting for them to happen on shift.
Traditional OJT is slow, inconsistent, and the mistakes are expensive. Textbooks teach theory only.
Every scenario practices real Abnormal Operating Conditions. Actions are logged. Plant Rounds create personal performance baselines. One-click Reference Logs become timestamped artifacts for shift handover, incident investigation, or training records. The B2B tier adds formal OQ record export and evaluator sign-off (ASME B31Q / 49 CFR aligned).
Today you buy OQ tracking, separate simulators, SOP tools, and audit prep from 5 to 7 vendors. This replaces most of that.
Plant Rounds pull your own baseline values into the trends. Pop-out trends support second-monitor use exactly like real DCS consoles. Accurate P&ID, faceplates, and capture/export become living reference during actual operations. Operators will actually pull this up on shift, not just during annual training.
Browser-based PWA. No $700k+ hardware sim. No dongles. No heavy IT deployment. Free for individuals and power engineering students. Team licensing and custom facility models (your P&IDs, setpoints, procedures) are available for companies that want standardized, defensible training across sites or for small operators who cannot afford traditional solutions.
Built by a 10+ year operator who trained and signed off real board operators. Senior people respect it instead of dismissing it.
The free Stabilizer is how you evaluate the quality before any conversation happens. B2B builds go further: your exact plant, your P&IDs, your setpoints, your upsets, your SOPs, modeled on the same engine. Cryo, amine, NGL, pigs, refrigeration, TEG, full Stabilizer. When you sign off on the build spec, that is what ships.

I spent over 10 years as a senior operator running real gas plants (Stabilizer and Cryo). I personally trained and signed off operators before they ran a board. The Stabilizer is the essential first board every operator masters: pig management, reboiler control, RVP, cascade, upset recovery. This is built as a high-fidelity reference tool operators can actually use on shift or in training, with zero risk to the live plant. The free Stabilizer experience is the public credibility window. B2B custom builds deliver complete plants (your P&IDs, procedures, upsets) using the same engine.

Built for the 99% of operators who will never sit in front of a $700,000 hardware-locked simulator. Browser-based. No license dongles. No IT deployment.
Real PI control loops with bumpless transfer. Real ISA-101 alarm discipline. Real cascade physics. The same plant a 10-year cryo operator runs at work, designed from scratch and rebuilt for the browser. Not a replacement for time on location. A bridge, so a new hire can build real pattern recognition before sitting at a live board.
We build complete custom simulations for real midstream gas plants: full Condensate Stabilizer operations (pigging and inlet, heat exchange, tower level/reboiler, compressor, RVP management, product handling), Cryogenic plants (mol sieve, turboexpander/expander, cold box, demethanizer, residue), Refrigeration/TEG dehy systems, Amine treating, NGL pumps and fractionation, and every supporting system and procedure. Same engine. Same decision-making focus. Your exact P&IDs, setpoints, upsets, and SOPs, modeled exactly as your plant runs them.
Most custom builds are scoped and delivered in 60 to 90 days.
