Replacing more than 30 end-of-life analyzers through tender, factory testing, installation and handover.
Explore →Interactive lab · Alarm management / OperationsAlarm Flood
Play the operator through an alarm flood, then see how priorities, delays and suppression change the same upset.
Explore →Engineering note · Capacity / Thermal systemsCapacity margin determines what happens after restoration.
Shortening a restart cannot remove a steady cooling deficit. Compare restored capacity, requested load and the heat left to remove.
Explore →Engineering note · Change / MaintenanceChanging a system that cannot stop.
Planned work removes redundancy before anything fails. Decide the stop points, the recoverable state and the evidence before the window opens.
Explore →Engineering essay · Virtualization / RecoveryConsolidate the hardware. Plan the recovery.
Moving control applications onto shared servers saves hardware and concentrates risk. The recovery has to be planned with it.
Explore →Interactive lab · Feedback / IdentificationControl Room
Tune a PID controller, compare responses and test uncertainty with reproducible studies.
Explore →Interactive lab · Capacity / Thermal systemsCooling Lab
Change heat load and cooling capacity, then inspect the thermal response and its limits.
Explore →Engineering note · Redundancy / MaintainabilityCount redundancy by what it survives.
N+1 and 2N describe how much equipment is installed. The useful question is which events the arrangement can absorb, including the ones that arrive together.
Explore →Engineering note · Dependencies / ReliabilityDependencies are part of the design.
Two supply paths can share one cooling dependency. Trace the relationships before counting the equipment.
Explore →Profile · Principles / Reliability / Recovery / ChangeEngineering principles
The principle behind each case study and note, linked to the work it comes from.
Explore →Engineering note · Alarm management / OperationsEvery alarm should ask for an action.
An alarm flood buries the cause of an upset. Priorities, delays and suppression each fix a different part of the problem, and none changes the process.
