Equipment and process CAPEX estimation - Turton/Peters/Seider correlations, CEPCI escalation, material/pressure factors, bare-module to grass-roots, AACE class 1-5, location and currency factors, mechanical-design-driven topsides/SURF/well rollups. USE WHEN: a task needs a Class 3/4 estimate for equipment, a flowsheet, topsides, SURF, wells or reservoir-to-market CAPEX. Anchors on CostEstimationCalculator and ProcessCostEstimate.
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 Equipment Cost Estimation Skill Class-3/4 (AACE 18R-97) order-of-magnitude to study estimates for individual process equipment and early process/facility CAPEX rollups - the bridge between sized equipment and a project economics model. Wraps Turton (5e), Peters–Timmerhaus, Ulrich, and Seider correlations with CEPCI escalation, material factors, pressure factors, and Lang/Hand factors. The preferred NeqSim path is mechanical-design driven: call each unit's `initMechanicalDesign()`, `calcDesign()`, then `getMechanicalDesign().getCostEstimate().calculateCostEstimate()` or let `ProcessCostEstimate.calculateAllCosts()` do that rollup for a full flowsheet. ## When to Use - Quickly cost a sized vessel, column, HX, pump, compressor, filter, reactor, mixer, splitter, or manifold - Build a **bare-module** → **total-module** → **grass-roots** stackup - Apply CEPCI to escalate published correlations to current year - Compare alternatives (e.g. centrifugal vs reciprocating compressor) - Produce a scope-safe `CostEstimateResult` for equipment, process, topsides, SURF, subsea, well, or field-development estimates …

How to install
mdr add equinor/neqsim/neqsim-equipment-cost-estimation@sha256:67204a754d41d9afThe 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.
