Real-world voyage outcomes and the technical foundations behind them.
North Sea crossing 100% inside the ECA. Optimised track reduced Sea State 4+ dwell time by 16.2 percentage points while delivering a 14.51% fuel reduction over a shorter great-circle track.
Brazilian departure to the Indian Ocean via a demanding sea-state corridor. Peak wave encounter 7.31 m south of Madagascar. Mean SOG 11.40 kn — 14.34% fuel reduction and 101 nm saved against the historical AIS replay.
Transatlantic voyage from Sikka (India) to Niterói (Brazil). Sea State 5+ waypoints reduced from 36.0% to 22.8%; Sea State 6+ halved from 6.4% to 3.4%. Full voyage on VLSFO with no ECA zones.
We present a neurosymbolic architecture for maritime route optimization that combines learned weather and ocean current forecasting with hard-coded physical and regulatory constraints — enabling transparent, auditable decisions that pure ML systems cannot provide.
A practical framework for fleet managers to continuously track and improve CII ratings using real-time route optimization data, with case studies across Supramax and Panamax fleets managing EU ETS exposure.
This paper describes how five specialized agents — route, fuel, emissions, safety, and trade — coordinate through structured communication protocols, and how game-theoretic optimization resolves conflicting objectives per voyage.
Time charterers pay for fuel but have historically lacked independent tools to verify voyage performance. This paper outlines a counterfactual analysis methodology for charter party disputes and off-hire determination.
