The platform

The published calculators reference digitalmodel — an open-source library of engineering analysis and calculation workflows. Library-first, importable, deterministic.

What it computes

Structural & Fatigue

  • S-N fatigue (DNV-RP-C203 calculator classes)
  • Spectral fatigue (Dirlik, Wirsching-Light)
  • Rainflow counting, SCF

Asset Integrity / FFS

  • API 579 Level 1/2 (GML, LML)
  • B31G remaining strength
  • Cathodic protection (DNV-RP-B401)

Subsea Pipeline

  • On-bottom stability (DNV-RP-F109)
  • Wall thickness (DNV-ST-F101)
  • Burst, collapse, combined loading

Hydrodynamics

  • Wave spectra (JONSWAP, Bretschneider…)
  • RAO processing, seakeeping
  • OrcaWave / AQWA bridges

Mooring, Riser & OrcaFlex

  • Catenary & lazy-wave risers
  • VIV and free-span screening
  • OrcaFlex model generation from YAML

Energy Data & Economics

  • BSEE production data & reporting
  • Arps decline curves, EUR
  • NPV / MIRR / IRR field economics

Where it is — and where it's going

We're specific about what's production-ready today versus on the roadmap.

Today

Engineering engine

Typed functions with worked examples and tests from real standard clauses. Same inputs, same outputs.

Next

Assessment scope

Project inputs, governing methods and limitations require engineering review.

Later

Design iteration

Brief → calculation package → checks → refinement. On the roadmap, not claimed as shipped.

Library-first, not locked in a UI

The calculations are functions, not a SaaS login. The library can be imported directly; project use requires qualified inputs and review of the applicable method.
