LensaSim Plant
Learn process control by running a plant.
A 3D training plant for process and automation engineers. Tune loops, ride out upsets, find the failing instrument and restart after a shutdown — and be scored on what the plant actually did.
By custom quote, for organizations and the people they train or assess. No installs; it runs in your browser.
Take over a shift
Each mission is a situation an engineer inherits: a loop left in manual, a slugging riser, a transmitter that has started to lie, a compressor about to trip.
Do the engineering
Work the plant as you would at a console: faceplates, setpoints and tuning, trends, alarms and the cause & effect of the safety system. Every action has consequences.
Learn from the debrief
Your attempt is replayed on our server and scored on the plant's performance. Then: what the engineers who wrote the procedure knew, and why it matters.
Plants in every process industry
Each sector brings its own plant set-ups, control strategies and failure modes. Three are live; more are on the way.
Oil & gas production
LiveWells, FPSOs, production platforms and storage: separation, compression, export and produced water.
- Wells and chokes
- Three-phase separation
- Gas compression and flare
- Crude export and storage
- Produced water
Refining & petrochemicals
LiveFired heaters, fractionation and conversion units: temperature, combustion and throughput.
- Fired heaters and combustion
- Cascade temperature control
- Pass balancing
- Burner management
Gas processing & LNG
LiveCompression, anti-surge, glycol dehydration and dew-point control — with amine treating, NGL recovery and liquefaction to come.
- Compressor anti-surge
- Speed and suction control
- Glycol dehydration
- Amine treating
- Turbo-expander plants
Chemical manufacturing
ComingReactors, distillation and utilities: exotherms, interlocks and batch sequences.
- Exothermic reactor control
- Distillation control
- Batch sequencing
- Utilities
Pharmaceuticals
ComingBatch and continuous manufacturing under GMP: bioreactors, crystallisation, clean utilities.
- Bioreactor control
- Crystallisation
- CIP/SIP sequences
- Data integrity
Six training tracks
Missions build competence in the areas plant engineers are judged on. Your record shows where you stand in each.
Control loop fundamentals
Measurement, setpoint and output; manual, auto and cascade; handing a loop over without a bump.
Controller tuning
What gain, integral and derivative do — and how to tell a loop is tuned too hard or too soft.
Abnormal situations
Upsets and machine trips: hold the plant inside its limits while the cause is dealt with.
Instruments & valves
Sticking valves, drifting transmitters: reading the trends to find what is really wrong.
Safety systems
Shutdowns, first-out, resets and safe restarts; burner management.
Operations & optimisation
More product, less energy, fewer emissions — within every limit the plant has.
For operating companies
Prepare new hires before they reach site, and let practising engineers keep and show their competence on the job. Every attempt is verified and kept on a competence record a supervisor can read: what was done, how the plant responded, and the score it earned.

- The safety layer as it is: independent SIS transmitters, latched trips, first-out, reset rules.
- Deterministic: every attempt is replayed and scored by our server, not by the browser.
- XP, ranks, badges and leaderboards — earned only by doing the engineering well.
