This is the MRV fleet, which is not the same thing as a fleet list. The grouping is the company that held the Document of Compliance when the filing was made, exactly as EMSA publishes it. A ship that changed manager during the year can appear under two companies, and a vessel that never traded to Europe does not appear at all.
