Cargo vessel types

What the filter represents

Vessel type is a field received in each movement. The application normalizes and translates some names to make searching easier, but it does not invent a category for rows without a type.

This is an operational list: it shows categories the domain can recognize in current data, not a complete taxonomy of every vessel.

• Filter movements by type
• Read the main movement guide

How to read the results

Use the category together with island, port, and date range. A type alone does not confirm the cargo, operation, or status of a movement.

When a row needs checking, compare its published fields with the official source.

Types you may see

Container ship and containerized cargo labels refer to movements associated with containers. General cargo and cargo vessel are broader categories used by the source for cargo ships.

Ro-Ro identifies vessels designed for roll-on and roll-off cargo. Tanker and bulk carrier describe other cargo categories. Dredger, tug, and research vessel appear when those types are recognized in the data.

Categories can vary with the text received from the source. The application translates and groups some names for search, but it does not classify a row that has no recognized type.

• Understand the other fields
• Search by vessel type

What the type does not prove

A vessel type alone does not prove the actual cargo, contract, company, capacity, or operation. It is a reading label for the published movement.

For an operational conclusion, compare the complete row, time, port, and official source. Report an inconsistent classification with the page context.

How to combine the filter

Start with Cargo and service when you want to narrow the view to recognized operational types. Then combine vessel type with island, port, or date range.

If the list becomes empty, remove one filter at a time. A category may have no rows for a port or period, and a source pause can also leave results temporarily unchanged.

Read the type together with the time and movement status. A category helps find relevant rows, but it does not turn a forecast into a confirmation.

Why categories can change

Names arrive from the official source and can have spelling variants. The application recognizes related forms to make searching more consistent, but future categories may not receive an immediate translation or grouping.

A new category should be read as received information, not as a promise about the cargo. If the source changes its fields, the published list can change after a validated update.

Use the correction form to report an unexpected label. Include the displayed type, port, and date so the record can be compared with the source.
