neqsim-subsea-and-wells SKILL.md skillA
neqsim-subsea-and-wells 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-subsea-and-wells@git:20261023.92beb0dPins git:20261023.92beb0d in mdr.lock. Pin the fingerprint instead.

Subsea systems, DNV-RP-F109 on-bottom stability, DNV-RP-F105 free span, DNV-RP-F101 corroded pipe, well design, SURF cost and tieback analysis with NeqSim. USE WHEN: designing subsea fields, screening pipeline/cable/umbilical stability or metal loss, sizing flowlines and umbilicals, estimating well cost, casing design, comparing tiebacks, or configuring trees, manifolds, boosters and risers.
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 Subsea & Wells Skill Reference for subsea production system design, well mechanical design, SURF cost estimation, and tieback analysis using NeqSim. For platform-drilled extended-reach wells (reach, torque and drag, slot and riser census) see the community skill `neqsim-erd-reach-screening`; NeqSim has no torque-and-drag class yet (NIP-1). For 3D well paths, position uncertainty and ISCWSA separation-factor anti-collision against offset wells (slot occupancy, sidetrack parent exit, target pull-back) see the community skill `neqsim-well-trajectory-anticollision`; NeqSim has no wellbore-positioning class. --- ## General well/SURF network integration Load `neqsim-pipeline-and-terminal-networks` for arbitrary gathering/injection pressure-flow topology and mixed pipe fidelity. See `docs/fielddevelopment/SURF_NETWORK_INTEGRATION.md` for the current source audit. Keep mechanical/design equipment as geometry and cost owners; use the existing LoopedPipeNetwork for detailed steady hydraulics and TwoFluidPipeNetwork for its bounded storage-node transient scope. Architecture builders and PLEM/template labels alone do not establish pressure-flow or conservation qualification. …

How to install
mdr add equinor/neqsim/neqsim-subsea-and-wells@sha256:d39d690f231c9e18The line at the top of this page pins the label git:20261023.92beb0d, 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.
