Screening-level utility-system design with NeqSim and the MCP designUtilities tool - fired Boiler, Deaerator, RefrigerationCycle, NitrogenSystem, multi-pressure SteamNetwork and the UtilitySystemDesigner that harvests demands from a run flowsheet. USE WHEN: sizing a utility duty/flow/power, estimating utility CO2 and cost, building a steam header balance, or exposing utility sizing through MCP. Levels: neqsim-utilities-specification; duties: neqsim-heat-integration.
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
# NeqSim Utility Design Skill Size and cost the core plant utilities with deterministic NeqSim models in `neqsim.process.util.utilitydesign`. This skill covers the **calculation** side (duties → flows → power → CO₂ → cost); use [`neqsim-utilities-specification`](../neqsim-utilities-specification/SKILL.md) to decide *which* utility levels to provide and [`neqsim-heat-integration`](../neqsim-heat-integration/SKILL.md) to derive the duties. ## When to Use - Sizing a fired steam boiler, deaerator, refrigeration package, or N₂ generator - Building a multi-pressure steam header balance (HP→MP→LP letdown cascade) - Aggregating heating/cooling/shaft-power/instrument-air demands from a flowsheet - Estimating utility CO₂ emissions and annual operating cost for ESG/screening - Exposing utility sizing through the MCP `designUtilities` tool These are **screening-level** models for early design, not detailed mechanical design. ## Classes All classes live in `neqsim.process.util.utilitydesign`, expose `public static final String SCHEMA_VERSION = "1.0"`, and provide `calculate()`, `toResultsMap()`, and `toJson()`. Each has a no-arg and a `String name` constructor. …

How to install
mdr add equinor/neqsim/neqsim-utility-design@sha256:cf1d1fa010a0760dThe line at the top of this page pins the label v1.0.0, 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.
