GenISys Bulkcarrier Design Dataset

Dataset on Hugging Face · Code on GitHub

217,999 random and repaired designs · 3,000 guided generations · 189 design parameters

GenISys supports research on the generation of integrated ship systems. Its synthetic bulkcarrier designs connect hull form, operation, compartment arrangement, and structure across 20 subsystems. A shared engineering pipeline evaluates 187 rule-based engineering constraints and five performance objectives: acquisition cost, annual cost, required freight rate (RFR), steel weight, and resistance.

Overview from the companion paper. The design representation contains 189 parameters, including 133 independent controls. The overview's population counts refer to the random/repaired dataset, before the additional generated samples.

From random designs to feasible systems

Coupled engineering requirements make fully feasible random designs rare: none of the 100,000 random designs satisfied every counted constraint. Equation-informed repair produced 117,999 additional proposals, including 16,247 fully feasible designs. The release retains successful, infeasible, and failed attempts, together with engineering responses, constraint labels, repair lineage, and frozen splits that keep related source-parent designs together.

Population	Records	Completed evaluations	Fully feasible
Random designs	100,000	81,675	0
Repaired designs	117,999	88,764	16,247
SCDDPM designs with RFR guidance	3,000	2,998	1,793
Total	220,999	173,437	18,040

The unified training table combines the 217,999 random and repaired designs. Generated samples form a separate evaluation population and are excluded from that table and its training/validation/test split.

Models and the companion paper

The dataset supports monolithic DDPM, hierarchical conditional DDPM (HCDDPM), and simultaneous conditional DDPM (SCDDPM). HCDDPM generates subsystems in sequence from completed predecessor context. SCDDPM updates subsystem-owned blocks from one shared noisy state, keeping coupled design decisions jointly revisable. Feasibility classifiers provide feasibility guidance, and an RFR regression model provides performance guidance toward lower cost per tonne transported.

The paper's architecture comparison. HCDDPM completes each block's reverse chain; SCDDPM assembles block proposals at every reverse step.

In the paper's cost reduction-guided sampling design study, designs were generated for a required voyage range of 5,000 nautical miles. Across five independent training runs per architecture, SCDDPM achieved 55.70% yield of fully feasible designs meeting a fixed low-RFR target, compared with 51.10% for DDPM and 47.54% for HCDDPM under separately selected guidance settings. This study evaluates qualifying yield across independently trained generators.

Included RFR-guided designs

This release also includes all 3,000 attempts from one saved SCDDPM fit, with 1,000 attempts at each voyage range. RFR is the modeled break-even freight charge per tonne transported, including annualized capital costs.

Voyage range	Attempts	Fully feasible	Mean feasible RFR (£/t)
1,000 nmi	1,000	612	8.16
5,000 nmi	1,000	593	18.81
8,000 nmi	1,000	588	27.28

Distributions include completed, fully feasible designs; feasibility annotations use all requested attempts. These saved-fit samples are a separate cohort from the paper's five-fit confirmation study. Different voyage lengths represent different missions.

Access and use

Choose the unified, random, repaired, split_assignments, or generated_scddpm_rfr subset. See the dataset guide for file schemas, loading examples, identifiers, split conventions, and source provenance. The companion GitHub repository provides model training and sampling, dataset construction, the ship evaluator, and CadQuery visualization.

The figure guide identifies all nine current manuscript figures. Packaging scripts can refresh those graphics independently of the released data; see the publication update. Current evaluation, table-generation, figure-generation, and arXiv build tools are maintained in the code repository's evaluation utilities.

Feasibility describes satisfaction of the formulated engineering constraints. Preserve recorded failures and label availability when training or comparing models.
