Optimize every
voyage.
The right data for the right decision in your voyage planning: recommended routes built on the ocean currents that are really there.
Real output · Sabine Pass → Port Everglades on live forecast currents. Blue: recommended · Red: same-ETA eco · Dashed: rhumb line
93 real voyages. Velum was faster on 85.
We took 18 months of one tanker's noon reports and ECDIS log and had Velum plan every voyage using only the forecast published before the ship sailed.
About 2.6 t of marine diesel per voyage: 155 t of diesel and 495 t of CO₂ a year. Diesel at ~$1,400/t (Gulf Coast, October 2026). The $75,000/day charter rate is an example; saved time pays when the ship's next fixture can use it. Vessel and operator not named.
A passage plan, not a straight line.
You get a chart and a waypoint table you can work from: course, distance, speed through the water and speed made good on every leg.
Live currents
Several leading ocean-current forecasts blended into one field, so a voyage crosses from one to the next without a seam.
Recommended routes
A recommendation, not an order. Velum plans around charted safety fairways, traffic separation schemes, the Florida Keys PSSA and a five-mile offshore standoff, and gives your officers the data to make the call.
ETA, fuel and CII
Give a speed and get an ETA, or a required arrival and get the speed. Fuel, CO₂ and an IMO CII rating on every route.
The gain depends on the water.
Single voyages planned on live forecast data: recommended route against the direct route, under the same currents. Short coastal legs gain little; long crossings gain the most.
| Voyage | Distance | Time & fuel saved | Same-ETA eco |
|---|---|---|---|
| Miami → Norfolk | 733 nm | 3.8% | 8.3% |
| Sabine Pass → Port Everglades | 892 nm | 3.5% | 9.6% |
| Savannah → Sabine Pass | 1,258 nm | 3.3% | 7.4% |
| Galveston/Houston → Boston | 2,070 nm | 4.4% | 13.2% |
| Corpus Christi → Boston | 2,172 nm | 6.2% | 14.1% |
Same-ETA eco is the fuel saved by riding the current and easing the engine to arrive at the same hour. Fuel here uses a generic performance curve; we calibrate to your noon reports before quoting yours.

We re-run your last 12 months of voyages on the currents that were really there and send back the hours, fuel and CII band you could have had. No integration, no install.

"Most routing software treats a voyage like an abstract shortest-path problem."
Velum Tech was founded by a licensed deck officer who sailed oil tankers and kept meeting tools that ignored both the ocean and the rulebook. Every routing decision traces back to something a mate has to answer for on watch.
We use AI to move faster on research and verification, not to decide where your ship goes. That decision stays with you; Velum gives you the right data to make it.
