Xeneta, trusted by the world's biggest buyers & sellers of containerized and air freight

‘Capacity’ reflects the supply side of ocean freight — how much space, measured in TEUs, carriers schedule on a route. When capacity tightens, rates increase.

Unlike others, Xeneta tracks the current offered and blanked TEU capacity across 160,000+ port pairs, updated daily and with historical data and a 3-month forward view — for each carrier alliance.

XENETA CAPACITY DATA

What's in the dataset

Carriers adjust their scheduled supply through blanked sailings and schedule updates. Offered capacity reflects the carrier committed capacity on each trade, calculated from their proforma schedules. Blanked sailings, the cancelled voyages, are the primary way carriers reduce supply on a lane.

Historical and current TEU space carriers have scheduled on a corridor or port pair, plus a 12-week forward view, and for each carrier alliance.

Historical and current TEU volume of blanked sailings on a port pair — how much scheduled capacity carriers have pulled — and for each carrier alliance.

Use Case Scenarios

When you'll use this data

Market monitoring & risk management

Track offered capacity and blanked sailings on your key corridors, or port pairs. Spot patterns early, flag the risk internally, and go into supplier conversations with data.

Spot buying / react to market shifts

Before making bookings, check offered capacity and blanked sailings on the lane.

Sourcing & tendering

Use the 3-month forward view to time your tender. If capacity is tightening into your contract window, move early. If supply looks loose, hold and let competitive pressure work in your favor.

Measure carrier & LSP performance

See which carriers and alliances are deploying capacity and which are pulling it on your lane. Use it to inform carrier selection and pressure-test how a carrier explains their pricing.

Sources & data processing

How the data is collected

Xeneta's offered and blanked capacity data is built on carrier proforma schedules — tracking which vessel is assigned to which sailing, on which route. Offered capacity in TEU is calculated from the registered specifications of each assigned vessel, standardised and cleaned across all carriers and services. When a sailing is blanked, that vessel's capacity is removed from the offered figure. The expansion of our data coverage is made possible by Xeneta's acquisition of eeSea in 2025.

Collect

Carrier Schedules + Vessel Registry Data

Carrier proforma schedules, vessel registry data, and port schedule feeds.

Cleanse

Error-checked

Schedule updates reconciled against the original plan, vessel assignments verified against IMO-registered specifications, blanked sailings flagged, and duplicates removed.

Normalize

Normalized

Map sailings to port pairs and trade lanes, translate vessel deployment into weekly TEU, and attribute capacity to carriers and alliances.

Validate

Quality gated

Cross-check against actual vessel movements from AIS, so the schedule-based capacity view stays honest when services run off-plan.

Process

Delivered how you need it

Offered capacity and blanked-sailing counts surface in the Xeneta platform, API, and reports.

Frequently asked questions

The most common questions we hear from procurement, supply chain, and freight forwarding teams evaluating Xeneta.

What counts as a blanked sailing?

A blanked sailing is an entirely cancelled voyage — the vessel does not run on that rotation. Blanked sailings remove offered capacity from the market on the week they were scheduled to operate.

How far ahead can I see offered and blanked capacity?

Up to 12 weeks forward, based on the carrier’s published schedule. As carriers publish updates, the forward view refreshes daily — so you can see new blanks appear before they hit the market.

Why track blank sailings if I just care about rates?

Capacity moves before rates do. Carriers adjust deployment first, and spot rates typically follow within a few weeks. Watching blank-sailing volume — especially on major corridors — gives supply chain and procurement teams a leading indicator, not a lagging one.

Where does the data come from?

Xeneta's offered and blanked capacity data is built on carrier proforma schedules — tracking which vessel is assigned to which sailing, on which route. Offered capacity in TEU is calculated from the IMO-registered specifications of each assigned vessel, standardized and cleaned across all carriers and services. When a sailing is blanked, that vessel's capacity is removed from the offered figure. Data is cross-checked against actual vessel movements from AIS to ensure the schedule-based view stays accurate when services run off-plan.

Can I compare capacity across carrier alliances?

Yes. Offered capacity and blanked sailings can be broken down by carrier alliance on the same port pair — so you can see which alliance is deploying the most space and which is pulling back.
