Iran
Shipping Industry Overview
Each vessel’s current registered owner and manager (broken-up ships excluded), deduplicated by IMO before calculating vessel totals and DWT. Vessel types use the same categories as the orderbook. These records do not establish verified control or active service. Company country differs from vessel flag; vessels can appear in more than one country.
DWT coverage: 860 of 1056 vessels. Build-year coverage: 1048 of 1056. Classification recorded: 420 of 1056. Age uses calendar build year; missing, pre-1900 or future years are “Unknown”. Missing DWT is excluded, not treated as zero capacity.
The 18–21-year age group is an age indicator only. Actual survey due dates are not available here. Repair visits are historical records labelled “repair”, not proof of a commercial preference. Company and group fleet totals can overlap.
