. Video of the tugs pushing the ship to ground it in this article (Tower Dog can translate):
Translation of the latest Newspaper blurb:
The 2 ships were in VHF contact with each other, the tanker told the Navy ship to turn to avoid collision.
The Marine ship traffic controller was also on the VHF, at first he did not know which ship just popped up on the radar, they
never checked in.
The Navy ship did navigation training on the bridge before and during the collision.
(The above is no official version of any investigation, just random info leaked to a newspaper)
