equinor/neqsim

Agent Claude Code

Performs root cause analysis on process equipment using NeqSim's diagnostics framework — integrates multi-source reliability data (IOGP/SINTEF, CCPS, IEEE 493, Lees, OREDA), plant historian time-series, STID design conditions, and process simulation to produce ranked failure hypotheses with Bayesian confidence scoring.

neqsim help

26

equinor/neqsim

Agent Claude Code

Routes engineering requests to the most appropriate NeqSim specialist agent. Analyzes the user's question, classifies it by domain, and delegates to the right agent — or composes multi-agent pipelines for complex cross-discipline tasks. Use this when you're unsure which agent to pick.

equinor/neqsim

Agent Claude Code

Takes a process simulation task description and delivers a complete, tested Jupyter notebook. Uses neqsimdevsetup for local development and produces Colab-compatible output. This is the fast path for getting working process simulation notebooks.

equinor/neqsim

Agent Claude Code

Solves process-engineering problems using the NeqSim Java API with proportional depth: quick answer-first calculations, notebook-backed studies, or full reports. Delivers auditable task folders with validation evidence, runner-executed notebooks/scripts, and reports when needed. When NeqSim lacks a needed capability…

equinor/neqsim

Agent Claude Code

Reads Honeywell UniSim Design / Aspen HYSYS .usc files via COM automation and converts them to running NeqSim ProcessSystem / ProcessModule models. Extracts fluid packages, components, operations (45+ typed operation handlers including reactors, columns, controllers, adapters), streams, sub-flowsheets, and topology.…

equinor/neqsim

Agent Claude Code

Coordinates screening-level utility-system DESIGN with NeqSim — sizes fired steam boilers, deaerators, vapour-compression refrigeration, on-site nitrogen generation, and multi-pressure steam networks, aggregates plant utility demands from a run flowsheet, and runs the agentic closed loop that optimizes a two-stage…

equinor/neqsim

Agent Claude Code

Acts as a hostile peer reviewer for a draft paper BEFORE submission. Reads paper.md + results.json + approvedclaims.json and returns a structured critique covering novelty, evidence, statistics, replication, framing, figures, and discussion depth. Produces a list of required fixes that scientific-writer must address…

algorithm-engineer

36

equinor/neqsim

Agent Claude Code

Inspects NeqSim's current flash algorithm implementation, identifies improvement opportunities, proposes code-level changes with pseudocode, and creates implementation tickets. Does NOT merge code — all changes go through validation.
