Thailand
Shipping Industry Overview
Recorded shipowner/shipmanager links, deduplicated by IMO before calculating vessel totals and DWT. These links do not establish current control or active service. Company country differs from vessel flag; vessels can appear in more than one country.
DWT coverage: 1300 of 1483 vessels. Build-year coverage: 1474 of 1483. Classification recorded: 505 of 1483. 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.
