Hi
Just might have been the 42000 Grt CAPE TEXEL which is red and has UPT on the side in white letters... arrived Ro'dam 8th, so could have been at anchor between the time you saw her and berthing. Not quite very large but a good size one.
Not many tanker companies have three letters on the side of orange/red hulls... this one actually has quite an orangy red hue...there are pics of her on Shipspotting.
Any ideas on colour of funnel and superstructure or how many cranes she had amidships? Also, was she bigger than the Urals Princess or similar/smaller? Per ShipAIS history there seems to have been a line of largish tankers going up with the Front VLCC , Petrozavodsk , Iasonas, and the LPG Captain John NP all ahead of this one.
Cheers, Ron
