Flow assurance patterns for NeqSim. USE WHEN: predicting hydrate, wax, asphaltene, CO2/H2S corrosion (NORSOK M-506), mineral scale and brine mixing, valve scale drift and remediation, sulfur S8 deposition, metal-loss screening, pipeline hydraulics, DNV-RP-F109/F105/F104/F110/F114 screening, water hammer, slug flow, thermal analysis or inhibitor dosing. Code patterns plus the governing standards for every threat.

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

# Flow Assurance Analysis with NeqSim

Consolidated guide for all flow assurance threats — hydrate, wax, asphaltene, corrosion,
hydraulics, water/liquid hammer screening, slugging, and thermal management — with
NeqSim code patterns.

> A complete study report with pipeline drawings (route, profiles, hydrate margin, threat matrix,
> validation) is produced by `neqsim flow-assurance-report` — see the
> `neqsim-flow-assurance-study-report` skill. This skill stays the calculation reference.
> A whole subsea SURF network (templates, injection, risers, umbilical, concept comparison) is
> generated, solved and documented by `neqsim surf-study` — see the `neqsim-surf-design-study` skill.
## When to Use This Skill

- Hydrate formation temperature/pressure prediction
- Hydrate inhibitor dosing (MEG, methanol, ethanol)
- Wax appearance temperature (WAT) and wax deposition risk
- Asphaltene stability screening (de Boer, CII)
- CO2 and H2S corrosion rate estimation
- Elemental sulfur (S8) deposition risk at pressure/temperature letdown (compressor inlets, control/letdown valves, dry-gas seals, filters)
- Pipeline pressure drop and temperature profile

How to install

The exact contents, by fingerprint
mdr add equinor/neqsim/neqsim-flow-assurance@sha256:378ef657740bfb78

The line at the top of this page pins the label git:20261104.a55262f, 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.
