This tanker has called at Rotterdam for the first time after having been employed in the Far East since she was newly built. On Aug. 29th she was outbound, and passing the New Waterway towards Hook of Holland. Please have a look at:

At first it seemed more a technical problem than a deliberate occurence. But since it stopped abruptly, it may have been a controlled emission.
It certainly did not look like an "ordinary sooting". No master would dare to do that voluntarily in the Rotterdam port area without risking a heavy fine ! FYI she did not lose speed. The signals did not indicate a pilot on board. Who can shed some light on this ?
