I don't read German, but I can find reports of the same SIZE chip getting stuck on the Elbe and requiring 12 tugs to free it. The ship was called the CSCL Indian Ocean.
>On February 3, 2016 CSCL Indian Ocean grounded in the River Elbe, while approaching Hamburg, Germany. Her rudder controls were reported to have malfunctioned. It took almost a week to free her from the sandbank, because she grounded at high-tide. Her fuel was unloaded, and she was finally freed, February 9, six days later, during the next spring tide. Twelve tugboats were required to assist in freeing her. Two dredgers had helped cut away at the sandbank, near the grounding.
Thats.. almost literally unbelievable. I almost want to suspect that that's a code name? For any sufficiently large ship that blocks a major waterway? Incredible.
There are limits to how big a ship can be and still transit a specific route, usually defined by the radius of curves in a canal or the length of a lock.
Furthermore, some of the world's main waterways such as the Suez Canal and Singapore Strait also restrict the maximum dimensions of a ship that can pass through them
the problem was the slow speed. i think even a small ship gets pushed by the wind at slow speeds. however a small ship can speed up faster, and it doesn't cause as much damage if it does crash into something.
that was the very same ship
EDIT: no, the incident needing 12 tugs was a different ship. see comment below.
