Real engineering problems on each facility, easiest first. Passing one unlocks the next.
Oil & gas production
FPSO production train

Your first shift: hand a loop back to AUTO
The HP separator level was left in manual after maintenance and it is creeping up.

Level into flow: restore the cascade
FIC-100 is holding a fixed flow, so nothing is controlling the HP level — and the wells are about to change.

The slow swing: an over-integrated level loop
The HP level swings every few minutes, and the whole train downstream swings with it.

Riding out a slug
W-103's riser has started slugging, and the HP separator is running high.

The loop that wouldn't settle
The interface level has been cycling for days. Retuning hasn't helped. Find out why.

Trust, but verify: a drifting transmitter
LIC-100 is holding 50 % perfectly. The HP separator may not be at 50 %.

Compressor trip!
The gas compressor is about to trip. Keep the plant up and the flare small.
Advanced · Abnormal situations · 12:00 plant time · 150 XP
Locked - 8
Water breakthrough
Two wells are watering out. Keep the crude dry and the sea clean.
Advanced · Operations & optimisation · 20:00 plant time · 150 XP

Back from a shutdown
The plant tripped overnight. Find out why, and bring it back safely.

Push for production
The chokes are conservative. Produce as much oil as the plant will safely take.

Refining & petrochemicals
Crude charge heater
- 1
Bring the coil outlet to temperature
The heater is running cold on manual. Get the crude to 360 °C and hand it to the controller.

Fuel gas swings: close the cascade
The fuel gas header is swinging and the COT swings with it. The fix is already installed.
Practitioner · Controller tuning · 15:00 plant time · 100 XP

Hot tubes: balance the passes
One pass is running hot. Protect the tubes without losing throughput.
Advanced · Abnormal situations · 15:00 plant time · 150 XP

Burn less fuel: trim the excess air
The heater is running with far too much air. Save fuel — and stay safe when the afternoon heats up.
Advanced · Operations & optimisation · 20:00 plant time · 150 XP

Heater trip and relight
The heater is about to trip. Bring it back the way the burner management procedure says.

Gas processing & LNG
Gas compression & dehydration
- 1
Gas to flare: close the speed cascade
The compressor is running slow on manual and the plant is flaring gas it should be exporting.

Export shut-in: keep the compressor out of surge
The pipeline is about to shut in your export. The anti-surge controller is in manual.

A hot afternoon: keep the gas dry
The afternoon heat will push wet gas into the pipeline. Keep it on specification without cooking the glycol.

Contactor upset: find what is wrong
Water in the export gas is climbing and the contactor is losing glycol. Work out why, then fix it.

Compressor trip: restart on recycle
K-300 has tripped and the plant is flaring everything. Find why, and bring it back safely.
