That is not an uncommon way to build big ships
In another Lurssen yard nearby they should be able to lift her if necessary to stick the bow on.
The power package on this is something untried by this yard before, I am of the understanding that all that part if the project was sourced out of house from another builder who had done a lot of R & D on it and the project never went ahead.
It was briefly shown on YF
A few years ago if anyone wants to try and work out what it was.
