NeqSim rotating-equipment studies. USE WHEN: dry gas seal or seal gas conditioning troubleshooting, regulator JT condensation, primary vent leakage, buffer/separation gas, API 692/ISO 6368 scope, startup and standby margins, compressor vendor maps/trains, turboexpanders, pump NPSH/API 610 or mechanical screening. APIs: DryGasSealAnalyzer, SealGasSupplyConditioning, DryGasSealMonitor, LabyrinthSealFlowCalculator, CompressorThermalModel.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Rotating Equipment Design ## When to use this Use this skill when an agent needs to create, correct, apply or interpret compressor, turboexpander or pump performance maps, operating envelopes, operating profiles, or first-pass mechanical checks. Load `neqsim-compressor-antisurge-recycle` for recycle-control topology and anti-surge dynamics. This skill covers machine performance/design API and data validity, not a vendor-certified selection. ## Class map | Class | Package | What it does | Verified API | |---|---|---|---| | `CompressorChart`, `CompressorChartInterface` | `neqsim.process.equipment.compressor` | Stores speed curves and retrieves head/efficiency at flow and speed | `addCurve(double,double[],double[],double[])`, `getPolytropicHead(double,double)`, `getPolytropicEfficiency(double,double)` | | `CompressorChartReader`, `CompressorChartJsonReader` | `neqsim.process.equipment.compressor` | Loads curve data and attaches chart curves to a compressor | `setCurvesToCompressor(Compressor)` | …

How to install
mdr add equinor/neqsim/neqsim-rotating-equipment-design@sha256:7de68431918c7450The line at the top of this page pins the label git:20261107.183f9c9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
