CBO Supporter left Aberdeen on 9th January and arrived Rio 10th Feb 2021 at 21.16 UTC

But I couldn't find that any sisters are operated by CBO, which is the beginning of the almost-readable name on the stern - and clearly seen on the bridge logo. And CBO SUPPORTER is operating Rio area (perhaps someone has AIS backtrack).

David, CBO Supporter originates from the STX Braila and Brevik yards, who produced many ships of that design. (UT776)

CBO SUPPORTER (IMO 9448528), I don't think that she has any sisters.
But where has the previous answer gone - was it different?

Helllo Juergen,

Very difficult !!

I was 10 miles from the ship !!
