neqsim-process-safety SKILL.md skillA
neqsim-process-safety from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-process-safety@v1.5.0Pins v1.5.0 in mdr.lock. Pin the fingerprint instead.

Process safety methodology - barriers, PSFs/SCEs, HAZOP, LOPA, SIL per IEC 61511, integrated safety response, change revalidation, bow-tie, risk matrix, TR3001 overpressure studies, trapped-liquid rupture. USE WHEN: a task needs barrier registers, hazard identification, LOPA, SIF SIL assignment, ESD/blowdown/relief/flare evidence, safety revalidation, overpressure governing cases, PFP demand or risk evaluation. Anchors on neqsim.process.safety.barrier, .risk, .overpressure, .rupture.
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 Process Safety Skill Systematic hazard identification, layer-of-protection analysis (LOPA), and safety-integrity-level (SIL) determination — the quantitative half of process safety that complements depressurization (`neqsim-dynamic-simulation`) and relief sizing (`neqsim-relief-flare-network`). ## When to Use - HAZOP / HAZID node walkdown with deviation guidewords - Barrier management for PSFs/SCEs with document evidence and performance standards - LOPA for a specific scenario — calculate residual frequency and required RRF - SIL determination for an SIF — IEC 61508 / IEC 61511 verification - Closed-loop SIF execution from live process signal through MooN voting and final element - Bow-tie analysis (top event with threats + barriers + consequences) - ALARP / risk-matrix scoring (5×5) - Trapped-liquid fire rupture screening for blocked-in liquid-filled segments, including PFP demand and source-term handoff - Overpressure-protection study for a protected item — enumerate credible relief contingencies, select the governing case, size the PSV, and check TR3001 / API 521 compliance …

How to install
mdr add equinor/neqsim/neqsim-process-safety@sha256:7c561a01618bba8bThe line at the top of this page pins the label v1.5.0, 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.
