Op³ generates publication-quality figures across all three pipeline stages using opsvis (OpenSeesPy), PyVista (OptumGX), and matplotlib/welib (OpenFAST). All figures are reproducible:

Tier 1: Defense Slides 

VHM Failure Envelope with Scour Degradation

V-H failure envelope shrinking with scour depth

Three panels showing: (a) V-H interaction envelopes at 5 scour depths with design load marker, (b) vertical and horizontal capacity retention vs S/D, (c) radial factor of safety trajectory from 1.89 to 1.29.

Cross-Pipeline Composite (The Thesis in One Figure)

Three-panel composite: OptumGX springs, OpenSeesPy mode shape, OpenFAST time series

OptumGX-derived foundation spring profile with bucket sketch,
OpenSeesPy first mode shape at f₁ = 0.275 Hz (Mode B),
OpenFAST aeroelastic response (generator power + blade root moment).

Scour Progression Sweep

Four-panel mode shapes at increasing scour depths

Mode shape evolution at S/D = 0, 0.1, 0.3, 0.5. Frequency drops from 0.316 to 0.309 Hz (-2.1%). Factor of safety transitions from green (1.89) through orange to red (1.29).

Mode C vs Mode D Dissipation Comparison

Mode C elastic vs Mode D dissipation-weighted stiffness profiles

(a) Stiffness profile overlay with w(z) weighting function inset. Mode D reduces stiffness by up to 84% at the skirt tip where plastic dissipation concentrates. (b) Calibration curve: f₁ vs dissipation exponent alpha, with field-measured frequency (0.244 Hz) as the target.

Tier 2: Journal Paper Figures 

Geotechnical Foundation Profile

Four-panel foundation cross-section with depth profiles

Publication-standard geotechnical figure: (a) bucket cross-section with soil layer shading, (b) undrained shear strength s_u(z), (c) initial stiffness k(z) as smooth depth curve, (d) ultimate resistance p_ult(z).

Rainflow Fatigue Damage Matrix

(a) 2D heatmap of fatigue damage contribution (range vs mean) weighted by Miner’s rule (m = 4), (b) cycle range histogram with DEL markers at m = 3, 4, 10.

Campbell Diagram

Rotor harmonics (1P, 3P, 6P, 9P) vs tower mode frequencies. The 3P crossing at 5.5 rpm near the operational cut-in speed is highlighted. The SSI effect (blue band) shifts f₁ from 0.316 to 0.275 Hz.

Moment-Rotation Backbone with Published References

Moment-rotation curves with cross-validation overlay

Op³ Mode C moment-rotation from pushover analysis.

(b) Cross-validation: DJ Kim 2014 centrifuge (red), Houlsby 2005 field (green), Barari 2021 Plaxis 3D (blue dashed), Op³ analytical M_y = 92.4 MNm at 0.6 deg (black star).

Tier 3: Interactive Dashboard 

Interactive 3D Foundation Model

The interactive model is available as a standalone HTML file: tier3_interactive_3d.html. Rotate, zoom, and click any spring node to inspect k(z) and p_ult(z) values.

Bayesian Digital Twin: Sensor Overlay

Field monitoring frequency tracking with Bayesian posterior

(a) 32-month OMA frequency tracking: raw scatter (gray), filtered (blue, 70.1% scatter reduction), Op³ prediction band (red). (b) Bayesian posterior scour distribution with decision zones: CONTINUE MONITORING / INSPECT / REMEDIATE.
