neqsim-subsea-layout-geometry

neqsim-subsea-layout-geometry is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 73 tokens per session (2,098 once invoked), scanned A, original, Apache-2.0.

A geometry calculator for a subsea field layout, using positions and water depths for wells, manifolds, templates, and a host facility. It calculates horizontal distances, three-dimensional tie-back lengths, and distances between layout points.

In plain words
What is it for?
Use it to estimate well-to-host step-outs, tie-back lengths, and a distance matrix for initial subsea layout planning.
Why use it?
It turns a map or coordinate list into consistent early routing measurements before detailed pipe routing and hydraulic work. The results are intended for screening rather than final design.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

neqsim-subsea-layout-geometry scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (examples/basic_subsea_layout_geometry.py, examples/subsea_field_layout_map.py, src/subsea_layout_geometry/__init__.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Subsea Layout Geometry

Use this skill for a quick, public geometry screening of a subsea field layout. Given the coordinates and water depths of wells, manifolds, and a host, it computes horizontal step-out distances, straight-line tie-back lengths (including water-depth difference), and a node-to-node distance matrix. It is intentionally simple and should guide users toward validated NeqSim routing and hydraulic workflows.

When to Use

  • When a user supplies a subsea map or layout (well, manifold, and host coordinates) and wants early tie-back distances.
  • When an engineer needs a node-to-node distance matrix for initial routing or step-out screening.
  • When an agent should explain that validated NeqSim hydraulic and routing methods are required for design-grade work.

Inputs

  • nodes: a list of layout nodes, each with name, x, y, optional water_depth_m, and optional kind (well, manifold, host, riser_base).
  • host_name: the node treated as the reference host for step-out distances.
  • coordinate_system: cartesian (x, y in metres) or geographic (x = longitude, y = latitude in degrees).
  • max_step_out_km: configurable public step-out guideline (constructor, default 50 km).

Outputs

  • step_out_km: horizontal distance from the host to each other node in km.
  • straight_line_km: straight-line distance from the host including the water-depth difference, in km.
  • pairwise_distances: node-to-node horizontal and straight-line distances and depth differences.
  • max_step_out_km: the largest host step-out distance.
  • step_out_warning: ok, watch, or high against the public guideline.
  • neqsim_available: whether the optional NeqSim package is importable.
  • assumptions: public assumptions and required follow-up.

Engineering Method

Horizontal distance between two nodes is the planar Euclidean distance for cartesian coordinates, or the great-circle (haversine) distance on a spherical Earth (radius 6 371 km) for geographic coordinates. The straight-line tie-back length is sqrt(horizontal^2 + depth_difference^2) using the water-depth difference between the two nodes.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
