Dirk, because there is no IMO number, which drives the search functions on this site and creates an indentity. A name and an MMSI number is just not enough. There are no tonnage data, just crude data on dimensions.

Why was Photo Category changed to "Unidentified Far Eastern Shipping (Admin use only)" from Tanker category, which it obviously is?

Dirk, I added the numbers to the two other shots of the same ship. There is no unfortunately search function on the site based the MMSI number, but for completeness I have added it.

Thanks pieter; see my photograph:

smaller Chinese vessels over 100 gt. don't seem to have IMO numbers.

MMSI:412039080, dimensions 65x10 meters, no IMO number.
