Predictive ETA Software for Ocean Freight

Stop Planning Around Carrier ETAs That Change the Day Before Arrival

Portcast's predictive ETA software forecasts when your containers will actually arrive, typically 15% better than carrier-reported times and 2 to 4 weeks ahead, and tells you where the delay hits and why. Built on data verified against live vessel tracking, it predicts at the milestone level, not just a single arrival date, giving your team ocean freight visibility they can plan around.

Carrier ETAs Are Wrong More Often Than You Think, and They Don't Tell You Why

Carrier-reported arrival times change late, often in the final days before arrival, and rarely come with a reason. Planning your downstream operations around a number that shifts without warning means constant firefighting, missed pickups, and last-minute costs. To plan with confidence, you need an arrival time you can trust days and weeks out.

Late Changes

Carrier ETAs often shift in the 24 to 72 hours before arrival, too late to replan around.

No Explanation

When an arrival time moves, carriers rarely tell you why, so your team is left guessing.

Disruption Blindspots

Carrier ETAs show where a shipment is today, not how congestion, weather, or strikes could change its arrival next.

What Is Predictive ETA Software?

Predictive ETA software uses machine learning to forecast when a container will actually arrive, rather than repeating what the carrier last reported. Carrier tracking portals reflect a single data source, updated at the carrier's discretion. Predictive ETA tools instead weigh many independent signals to model the real arrival time: live vessel position, carrier schedule changes, port congestion, historical lane performance, and market insights such as geopolitical events, port closures, and weather incidents.

Portcast's predictive ETA software is built specifically for ocean freight. Its domain-specific machine learning models draw on more than 70 data sources, with journey data continuously validated against live vessel AIS, carrier, and terminal data, making its predictions more reliable.

Portcast predicts at the milestone level, forecasting vessel berthing, container discharge, customs clearance, and gate-out availability, not just a single arrival date. But predicting when a shipment will arrive is only part of the value. Portcast also shows where the delay is likely to hit and why. Whether the issue is vessel congestion, port delays, discharge, customs, or another disruption, Portcast explains what is driving the ETA change, giving teams the context they need to plan ahead and take action.

Key Features of Portcast's Predictive ETA Software

AI-Predicted ETAs Built for Ocean Freight

Portcast's predicted ETAs and ETDs are typically 15% more accurate than carrier-provided times, even 2-4 weeks before arrival. Powered by domain-specific ML and continuously recalculated as conditions change, predictions stay stable throughout the voyage instead of shifting at the last minute. With milestone-level predictions, Portcast shows exactly where a delay is occurring and why, not just the revised arrival date.

Predicted ETAs typically 15% better than carrier ETAs, up to 2 to 4 weeks ahead

Forecasts at milestone level: berthing, discharge, customs clearance, and gate-out availability

Recalculated continuously as vessel position, congestion, and schedules change

Original and latest carrier ETAs retained alongside the prediction, to benchmark carrier performance

Every ETA change comes with the milestone it hits and the reason behind it, from port congestion to customs to weather disruptions

Built on Data Verified Against Live Vessel Tracking

A prediction is only as good as the data beneath it. Portcast combines carrier milestones with live vessel AIS tracking, geofenced port data, and terminal events, and where sources disagree, it surfaces the difference. That verified foundation is what makes the predicted ETA on top of it trustworthy.

Carrier milestones cross-checked against live AIS vessel data for accuracy and lower latency

Multiple independent sources combined for a broader, more complete view of the journey

AIS-observed departure and arrival times surfaced where they differ from carrier reporting

Every data point automatically validated before it reaches your prediction

Built on Data Verified Against Live Vessel Tracking

Delay Reasons and Root Cause, Explained

When a predicted arrival shifts, Portcast tells you where the delay hits and why. Because it predicts at the milestone level, it can point to the exact stage that is slipping, whether it is vessel congestion, a port delay, discharge, customs, or another disruption, and surface the cause behind it. That turns a change in ETA into context your team can act on and communicate, rather than a silent new date.

Pinpoints which milestone is driving the delay: berthing, discharge, customs, or gate-out

Identifies the cause: adverse weather, port congestion, a non-optimal vessel route, or disruption

Flags every container affected by a given disruption, so you can act across your book at once

Turns a shifting ETA into a proactive customer update instead of a reactive scramble

Delay Reasons and Root Cause, Explained

Visibility That Holds Even When Carrier Data Stops

Carrier data goes quiet more often than teams expect. Portcast reduces the latency of milestone updates and maintains visibility even when a carrier stops providing data, by drawing on multiple independent sources for a fuller picture of where your container actually is.

Multiple data sources give more than one perspective on container movement

Visibility maintained through gaps when carrier feeds go silent

Lower-latency milestone updates than carrier reporting alone

Congestion factored directly into predictions, combining port updates and geolocation data

Getting started

How Portcast's Predictive ETA Works

Three steps from search to plan, with congestion data included at each stage.

Add Your Shipments
Bring shipments in by container, booking, or bill of lading number, through the platform or the API. Portcast begins tracking and predicting automatically, with no per-carrier setup.
Model the Real Arrival Time
Portcast verifies carrier milestones against live vessel AIS data, then weighs vessel position, schedule changes, port congestion, dwell time, and historical lane performance across 70+ data sources to forecast arrival at milestone level, recalculating as conditions change.
Plan and Communicate Ahead
Your team sees an arrival time it can trust, with the reason behind any change. Act on delays early, update customers proactively, and push predictions into your own systems by API.

Predictive ETA Software: Frequently Asked Questions

Any other question that isn’t mentioned? Don't hesitate to get in touch.

How accurate are Portcast's predictive ETAs?

Portcast's predicted ETAs are typically 15% better than carrier-reported times, even 2 to 4 weeks ahead of arrival. Accuracy improves as the container gets closer to port, and for some customers reaches into the mid-90s percent a week out, though this varies by lane and carrier. Predictions are produced by domain-specific machine learning drawing on more than 70 data sources.

How is predictive ETA different from carrier tracking?

Carrier tracking shows the last event the carrier reported. Predictive ETA software models what will happen next, using multiple data sources and machine learning trained on historical lane performance, so your team can plan ahead rather than react. Portcast also explains why a predicted arrival has changed, which carrier tracking does not.

Can container tracking software predict port congestion?

Portcast factors real-time port congestion directly into its arrival predictions, combining port updates and geolocation data so your ETA reflects actual port conditions. When congestion is the reason an arrival shifts, Portcast surfaces it as the delay cause, and port congestion is also available as a standalone dataset for trade-route planning.

What data sources power Portcast's ETA predictions?

Portcast's predictions draw on more than 70 data sources, including live AIS vessel position, carrier schedule changes, real-time port congestion, dwell time, weather, and historical transit performance. Combining many independent signals, verified against live vessel tracking, is what keeps the prediction stable as conditions change.

What happens when a carrier doesn't update its data?

Portcast’s multi-source approach maintains visibility even when carriers go silent. By drawing on independent signals like AIS and port data, it reduces the latency of milestone updates and removes the “dark days” that appear when you rely on a single carrier feed.

How far in advance can Portcast predict container arrival?

Typically 2 to 4 weeks ahead of arrival, well before carrier-reported times tend to firm up, which often only happens in the final 24 to 72 hours. This lead time is what lets teams plan downstream operations rather than react to last-minute changes. This container ETA prediction is generated at milestone level, not just as a single date.

How does Portcast explain why an ETA changed?

When a predicted ETA is revised, Portcast shows both where the delay hits and why. Because it predicts at the milestone level, it can point to the exact stage that is slipping: berthing, discharge, customs, or gate-out, and name the cause behind it, such as adverse weather, port congestion, or a non-optimal vessel route. It also flags every container affected by that disruption, so you can act across your shipments at once rather than investigating one by one.

Is there an API for predictive ETA data?

Yes. You can pull live predicted ETAs, delay reasons, and risk data directly into your TMS, ERP, or customer portal. As a shipment ETA prediction software built to embed, it lets you deliver predictive visibility inside your own product. Documentation is available at portcast.stoplight.io.

What is ocean freight visibility?

Ocean freight visibility is the ability to see where your sea shipments are and when they will arrive, across carriers and the full container journey. Portcast provides predictive ocean freight visibility that goes beyond carrier updates, verifying movement against live vessel data and forecasting arrival with machine learning.
