-
Engineering-Constrained Bidirectional LSTM for Structural Integrity Prediction and Optimization of Offshore Jumpers
The BiLSTM surrogate behind the strength tool, and the constraint-filtered configuration search behind the design tool. Trained on about 150,000 finite-element models; validation RMSE about 0.07 unity.
-
Transformer-Based Surrogate for Operational Fatigue Assessment of Subsea Jumpers
A sectional-force transformer with DNV-RP-C203 post-processing, validated on a 1,000-run paired operating-state campaign.
Articles
What drives jumper unity values?
A feature-importance and ablation study of the BiLSTM: end expansion and pipe section dominate, geometry follows, and position matters modestly.
Why an inverse-surrogate model failed in practical jumper design
Differentiable inverse design looks elegant; with manufacturing limits and hard constraints it becomes brittle. Why a forward-only, constraint-filtering workflow wins here.
