Physics-informed performance intelligence

Know more. Burn less. Perform better.

Your ships already send the numbers every day. NavalBrain reads them, applies marine engineering and physics, and speaks your language: the dollar, per vessel, per day. You no longer have to question why each ton of fuel was burned, how much of it the hull is costing you, which retrofits actually pay back, and what to instruct the master mid-voyage.

The problem

You burn fuel every day. You see why twice a year, if at all.

Every ton of bunker leaves the tank for a physical reason — engine load, auxiliaries, weather, draft, trim, a fouled hull, a worn propeller. Today those reasons live inside the noon report as a single aggregate number, and the answers arrive at drydock, months late.

NavalBrain turns the daily noon report into four answers, every day: where the fuel is going, what the hull is costing you, which retrofits actually pay back, and what to instruct the master mid-voyage. Each answer denominated in dollars, grounded in physics, traceable to a standard.

Diagnose

First, see why every ton of fuel was burned.

Burning Intelligence.

Analyzes fuel consumption.

Physics-informed models that track daily fuel oil consumption and attribute every ton of consumed fuel to its physical cause (ME load, auxiliaries, weather, draft, trim, hull degradation, propeller residual, etc.), comparing reported consumption against a theoretical baseline.

Burning Intelligence fuel attribution: 45.5 tons of daily FOC decomposed into seven physical causes — ME load 21.5 t, auxiliaries 4.7 t, weather 7.0 t, draft 3.6 t, trim 1.8 t, hull fouling 5.8 t, propeller residual 1.1 t.

Each band is a physical cause derived from the noon report, vessel particulars, weather, and the theoretical baseline. The hull is a pie chart shaped like the ship: every ton, with its name on it.

Hull Intelligence.

Computes and forecasts hull efficiency.

Hull fouling index, historical analysis of hull degradation and severity updated daily, anchored to ISO 19030 and ITTC kS roughness scale, with drydock-aware trajectory modeling and forecast of the fuel cost attributable to the hull.

Hull Intelligence card. Live hull degradation trajectory aligned to ISO 19030. nb_drift today: 5.08 percent, 95 percent confidence interval 4.77 to 5.41. Forecast next 90 days: plus 1.4 percent drift. Fuel penalty today: $1,428 per day on 52.4 tons per day reported FOC. Data quality 4 of 5, provenance traced.

Every noon report, a new point on the curve.

Each noon report becomes a new point on the curve. The trajectory is anchored to the vessel’s sea-trial baseline, cleaned through a Kalman filter, and corrected against ISO 19030; the band shows the 95% confidence interval.

Then, decide and act with the dollar attached.

Retrofit & Finance.

Models retrofit ROI.

Resistance and economic models that test operational effectiveness and ROI for hull, propeller, and energy-saving-device retrofits, with regulatory impact analysis (CII, EEXI, FuelEU Maritime) per retrofit proposed.

Retrofit & Finance pipeline: four candidates — Pre-swirl duct, Mewis duct, Rudder bulb, Scrubber — evaluated through Design, Physics, Capital, and Regulatory stages. Pre-swirl duct is the winning recommendation; a 12-page NavalBrain report is produced as the deliverable.

Retrofit & finance
From engineering to capital.

Every candidate runs the same pipeline. The winner is the one that holds up across all four.

Retrofit and Finance decision pipeline Four retrofit candidates feed a horizontal evaluation channel. As a travelling light passes the four stage boxes (Design, Physics, Capital, Regulatory), each lights up. After the sweep, three candidates are muted and the winner emerges into the recommendation node, which is connected by a dashed tether to a generated NavalBrain report.

Decision Support.

Recommends decisions and live standing orders.

Operational recommendations and standing orders derived from the above three, each explainable along three axes: money (€/day), engineering (physics rationale), and law (regulatory and compliance). Contains LLM infrastructure scoped to each client’s fleet history.

Standing order recommendation: Stern-up trim +0.08 m, 91 percent confidence, expected voyage saving of $11,247. The card explains itself across money, engineering, and law.

Standing order card — Stern-up trim +0.08 m A document-style recommendation card with header stamp, action prose and expected saving, then sections for money line items, engineering rationale with a typeset delta R subscript T term and an inline trim diagram, and law with eight context/result boxes.

Deployment

Global coverage, per-vessel precision.

Every vessel streams AIS continuously, cross-referenced against its noon reports, route weather, and the sea-trial baseline. The platform works the same way whether you monitor three ships or three hundred.

Onboarding is a data feed, not a deployment. No hardware. No onboard software. No retrofit project on the superintendent’s desk.

How it’s built

No hand-waving. Every decision is defensible.

01
Physics foundation

ISO 15016 (speed-power trials) and ISO 19030 (hull and propeller performance) form the backbone. Baseline resistance from Holtrop & Mennen. Degradation priors from Townsin (1981, 2003). Every claim has a paper or a standard behind it.

Resistance models in Retrofit & Finance are likewise grounded in Holtrop & Mennen, with literature correction factors layered on top: Townsin for roughness, Schultz (2007) for biofilm.

02
Data architecture

Full audit trail from raw noon row to final drift value. Every derived variable carries a confidence score and provenance chain.

03
Honest trade-offs

Phase one captures combined hull and propeller degradation. Phase two separates the two signals. We disclose limitations openly in every pilot conversation.

04
Roadmap

Trim and stability intelligence. Age and coating-aware thresholds. Cross-fleet learning.

Regulatory frameworks

Aligned to the regulations your charterers and class society read first.

Methodology standards above describe how we model the physics. The regulations below describe the rules every output is checked against — from daily attribution through retrofit ROI to standing orders.

Aligned with CII EEXI FuelEU Maritime
Why it compounds

More accurate with every vessel. Every voyage.

Naval Brain gets sharper the longer it runs. The more of your fleet it sees, the better it knows your fleet.
