Six classes of maritime evidence problem

These pages map questions, possible data, methods, and evaluation targets. They do not claim that every capability is implemented or validated in the public demonstrator.

01

Maritime Domain Evidence

What can open sources establish beyond cooperative vessel reporting?

For

Researchers, public institutions, analysts, and maritime operators

Potentially relevant data

AIS samplesSentinel-1 SARSentinel-2 optical imageryPublic registries

The problem

Public AIS is partial and cooperative. Satellite imagery, registries, weather, and reporting can add context, but they have different coverage, timing, licensing, and error modes. A responsible method must show which source supports each conclusion.

Methods to test

  • Compare cooperative AIS observations with bounded SAR and optical samples
  • Record detection, association, coverage, timing, and uncertainty separately
  • Preserve gaps, disagreement, and alternative explanations
  • Require human review and cited evidence before escalating a lead

Evaluation targets

  • Measured detection and association performance on a defined sample
  • Visible source coverage, freshness, and missing-data states
  • A reproducible evidence record for each conclusion

02

Identity & Sanctions Evidence

Which vessel-risk indicators remain defensible when identities and behaviour change?

For

Compliance researchers, insurers, public institutions, and maritime analysts

Potentially relevant data

Official sanctions listsAIS samplesPublic registriesBounded imagery

The problem

A list match is only one form of evidence. AIS gaps, identity changes, ownership records, transfers, and imagery can be relevant, but none proves misconduct by itself. The question is how to combine them without turning indicators into unsupported allegations.

Methods to test

  • Resolve IMO, MMSI, flag, name, owner, and registry records with dates
  • Separate official designations from behavioural indicators and model inference
  • Corroborate material claims across independent source types where possible
  • Record false-positive risk, missing evidence, and the point at which the method abstains

Evaluation targets

  • Traceable identity and source history
  • Calibrated indicator performance on labelled cases
  • Clear boundaries between designation, concern, and insufficient evidence

03

Emissions & Regulatory Evidence

How should activity estimates, reported emissions, and policy rules be reconciled?

For

Researchers, ship operators, policy teams, and sustainability analysts

Potentially relevant data

EU MRV / THETIS-MRVAIS samplesPublic vessel particularsOpen metocean data

The problem

AIS-derived emissions are estimates, verified reporting has its own scope, and regulatory regimes use different boundaries and definitions. Combining them without a source and calculation record can create false precision.

Methods to test

  • State the applicable rule, geography, period, vessel scope, and reporting boundary
  • Estimate activity with documented vessel and fuel assumptions
  • Compare estimates with available verified or reported observations
  • Publish uncertainty ranges, exclusions, and sensitivity to key assumptions

Evaluation targets

  • Reproducible calculations for a bounded vessel or voyage sample
  • A visible reconciliation between estimated and reported values
  • Sensitivity ranges that show which assumptions drive the conclusion

04

Trade-Flow Inference

Which conclusions survive gaps, latency, cargo uncertainty, and aggregation?

For

Economic researchers, policy analysts, and maritime market observers

Potentially relevant data

AIS samplesUN ComtradePublic port statisticsVessel particulars

The problem

Port calls and vessel movement can illuminate trade, but cargo, utilisation, destination, ownership, and timing are not always observed. A useful flow estimate must distinguish direct observation from classification and inference.

Methods to test

  • Define the unit of analysis, time window, geographic boundary, and observation coverage
  • Keep vessel movement, cargo classification, utilisation estimate, and economic interpretation separate
  • Test sensitivity to missing observations, delayed feeds, and alternative classifications
  • Compare aggregate results with dated trade and port statistics

Evaluation targets

  • A reproducible flow estimate with an explicit coverage denominator
  • Error bounds for latency, classification, and missing observations
  • A statement of which economic conclusions the sample cannot support
Discuss a bounded trade-flow inference research question
05

Voyage & Port Modelling

When can open observations improve an arrival estimate?

For

Researchers, ports, terminals, carriers, and cargo owners

Potentially relevant data

AIS voyage samplesOpen metocean dataPublic bathymetryPort-call labels

The problem

An ETA model can look accurate on an easy sample and fail under congestion, weather, route change, anchorage, or incomplete history. The relevant question is performance against a defined baseline across conditions.

Methods to test

  • Define arrival, port-call, anchorage, and prediction-horizon labels
  • Compare simple baselines with vessel-history and metocean features
  • Evaluate by route, vessel class, horizon, and disruption condition
  • Report calibration, error distribution, exclusions, and failure cases

Evaluation targets

  • Performance against a named baseline on a bounded dataset
  • Error distributions rather than one headline accuracy measure
  • Documented conditions in which the model should not be used

06

Maritime AI Claims

How should a maritime-AI capability claim be tested?

For

Researchers, boards, investors, public institutions, and technical reviewers

Potentially relevant data

Technical documentationEvaluation datasetsProvider termsDated public sources

The problem

A polished maritime-AI demonstration can hide purchased data, narrow test conditions, leakage, weak ground truth, or dependence on one provider. Technical and strategic review should reconstruct the claim and identify what evidence would confirm or disconfirm it.

Methods to test

  • State the claimed prediction, decision use, baseline, and acceptable error
  • Trace data rights, coverage, labelling, transformations, model evaluation, and provider dependencies
  • Test performance across time, geography, vessel class, and difficult cases
  • Separate technical performance from market, regulatory, operational, and investment conclusions

Evaluation targets

  • A claim-and-evidence register
  • A reproducible evaluation design and dependency map
  • Clear disconfirming tests and questions that remain unanswered
