Looking for Portcast for Offshore Vessels? Here's Why You Won't Find It
Portcast has built a strong predictive-ETA platform for ocean container and air freight — tracking over 5 million data points a day across 370+ carriers to tell supply chain teams when a shipment will actually arrive. It's a genuinely useful tool for what it does. But it has nothing to do with offshore vessel chartering. If you're an offshore charterer and Portcast's name came up, here's the honest picture.

Why you won't find offshore chartering support at Portcast
If you're an offshore charterer looking at Portcast, a few things are worth knowing before signing up.
Predicting arrival, not chartering a vessel. Portcast forecasts when a container will arrive — it doesn't help you find, compare, or contact an available offshore support vessel.
Container and air freight only. Portcast's entire data model is built around scheduled container and air freight lanes; there's no offshore dimension in its coverage.
Different unit, different user. Portcast tracks containers for supply chain managers. Seavium sources whole vessels for offshore chartering desks — a different product entirely.
What Seavium does — built for a different job entirely
Vessel sourcing, not shipment prediction. Seavium is built for finding and comparing available offshore vessels, not predicting container arrival times.
Offshore-native criteria. DP class, POB, deck area, and draft are core to Seavium's data model.
Whole vessels, not container units. Seavium's entire dataset is scoped to offshore support vessel types.
Predictable subscription pricing built for offshore chartering teams, not container volume tiers.
Portcast pricing breakdown
Portcast does not publish list pricing. Its subscription is typically priced by container volume tier and is arranged directly with shippers, forwarders, and logistics technology companies.
FAQ
Does Portcast handle offshore vessel chartering?
No. Portcast is a predictive visibility platform for container and air freight — tracking shipments and forecasting arrival times, not sourcing or chartering offshore support vessels.
What does Portcast's ETA prediction cover?
Portcast predicts container arrival and departure times across ocean and air trade lanes, using machine learning on AIS, carrier, and port data — entirely within the container and air freight segment.
Is Seavium a competitor to Portcast?
No meaningful overlap. Portcast predicts container arrival times for supply chain teams; Seavium sources and compares available offshore vessels for chartering. Different products, different users.
Where should offshore charterers look instead of Portcast?
An offshore-specific chartering platform like Seavium, built around offshore vessel types and criteria, is the right fit — not a container ETA prediction tool.
