An AI Weather Router Gets a Class Approval. Read What It Covers.

Weather routing is one of the oldest jobs where computers help ships. Now the software is starting to use AI agents, and the first approvals are arriving.

The approval. VesselFront, a software company in Piraeus, says its VesselFront.AI system has received Type Approval from Bureau Veritas. The approval covers three things: how it calculates fuel consumption, how it forecasts emissions, and how it supports weather routing decisions. Bureau Veritas also certified the company's quality system in Piraeus.

How it works. Several small AI agents each watch one thing: the weather, fuel use, environmental rules, and how exposed the ship is to bad seas. Every route must stay inside hard safety limits that the AI cannot break: a maximum wave height along the route, northern and southern limits, and no-go areas. The company has applied for a US patent.

What the approval does not cover. It checks how the software calculates. It does not prove how much fuel it saves on real ships. No customers, no fleet size and no savings are published. As with almost every type approval, the company asked for the review and paid for it.

The same idea in leisure sailing. Two weeks ago PredictWind, used by more than a million sailors, added an AI that does not make its own forecast. It reads the routes from eight weather models and explains them in plain words, including where the forecasts disagree. That last part is useful for any ship: an honest router should tell you when it is not sure.

Why the hard limits matter. The most important part of this story is not the AI. It is the rule that the AI must stay inside limits a person sets. That is how AI should work on any bridge.

What to ask your routing supplier. Which limits can the master set, and can the system ever cross them? Does it show how sure it is about each route? And can you show results on ships like ours, measured by someone other than you? [Cyprus Shipping News · Marine Business News]
