Not entirely sure of the origin of this NOORDKAAP.
I think that she is probably the former tankbarge SHELL 61, built 1948 at Vlaardingen (ENI 02307151)
The dimensions seem about right (described now as 22m), and she has a similar raised bow-plating, and the same "kink" in her bulwarks amidships as in the only photo that I've found:

Also, out of sight in my photo, she has traces of a welded name on the starboard bow, just the letters "Sh", though not in capitals as in the binnenvaart photo, but like this: https://www.debinnenvaart.nl/images/boats/Shell%20%20%201%202312339.jpg
