Weilbach Optimizer, powered by Optimum Voyage

We are very happy to have partnered with Weilbach, and to see Optimum Voyage’s voyage optimization technology now available directly within the Weilbach platform as Weilbach Optimizer.

There is something quite special about bringing new voyage optimization technology into a company with a history going all the way back to 1755. More than 270 years of maritime experience combined with modern voyage optimization: a pretty good combination, if you ask us.

What Weilbach Optimizer does

Weilbach Optimizer works seamlessly with routes created in Weilbach Viewer. It analyzes vessel-specific performance together with high-resolution weather forecasts, currents and other data to evaluate millions of possible route variations for each optimization, while respecting the navigability and constraints of the original bridge-planned route.

The outcome is practical route options that help reduce fuel consumption, minimize heavy-weather exposure and improve ETA reliability, while always leaving the final decision where it belongs: with the crew.

It is a strong combination of Weilbach’s navigation solutions and our optimization technology, making advanced weather routing and voyage optimization available directly to users onboard. Optimum Voyage is the optimization engine behind Weilbach Optimizer, delivered through the same technology as our API service.

"With Weilbach Optimizer, crews get practical, navigable route options built on the same engine that optimizes more than 700 vessels every day, and the final decision always remains on the bridge," says Martin Hjorth Simonsen, CEO of Optimum Voyage.

"We wanted to bring an advanced optimization technology with proven track record into our offering to our customers and distribution partners. With more than 50+ shipowners already using the technology with great success worldwide we are very excited to bring Weilbach Optimizer to market," says Daniel Friis, CCO, Weilbach A/S.

See it at SMM Hamburg 2026

Weilbach Optimizer is showcased at SMM Hamburg, 1 to 4 September, at the Weilbach stand: Hall B1 ground floor, Stand 301. There is a fair chance you will find a couple of familiar faces from Optimum Voyage around the stand as well; Martin and Thor are at SMM on Tuesday and Wednesday.

We are proud to be working together with another Danish maritime technology company, and very much looking forward to what comes next.
