Thanks Ian ,that answers my question, the IMO number used for several shots is indeed incorrect. The ship apparently has no IMO number at all. And yes I should have written POnta Negra, not PUnta Negra.

The correct name of this Bunkering Tanker is LN PONTA NEGRA as davidships comments 10 years ago:

But is the IMO correct? I can not find any trace that the cargo ship Punta Negra (5281910) built by CCN Lahmeyer in 1963 was converted to a tanker. She was reported damaged in July 1976, and subsequently broken up in Brazil in 1978. These pictures all date from 20 years later.

The correct name is PONTA NEGRA
