I remember seeing her leaving Rotterdam a few days later.

Thanks a lot, shipspottr. I believe she was #58 of 64 bulkers of the "Sovetskiy Kudozhnik" type and subtypes (projects 584, 584/E and 584/1?). Grounded off Morro Castle, Puerto Rico, in 1999.
Only two of 64 vessels appear to be still in service, namely #61 Viktor Kingissepp (as Dong Feng, 8521000) and #64 Skulptor Matveev (as Xuazxou, 8610227).

Wow, what a rare sight, and a first here on shipspotting - congrats!
