Cross-reference IMO numbers with deadweight tonnage (DWT), the vessel name and the check-digit validation. In batch or one at a time.
Upload a spreadsheet of IMO numbers and get the DWT, vessel name, size class and validation.
Enter an IMO number to see the DWT without uploading a spreadsheet. Vessels covered by the EU MRV scheme also show ship type, flag, efficiency and CO₂ emissions.
