There was no failure at all!That video has been around for years. I believe it was either a steering failure or a gear failure that triggered the whole event.
After the ship plowed through the boats at the marina, they headed out to sea, without as much as a VHF call.
Norwegian coast guard boarded the vessel an hour later, and held the captain for questioning.
A dreadfull act of the captain with no thoughts for the boats.
I could link to articles to about the incident, but they are all in danish or norwegian.
