Wind farm installation vessel at work

Another Wind farm installation vessel at work FYE:

All I see is electrons playing. Does this vessel actually exist?

Shows up OK here.(??)
Another source:

What I mean is that the clip is all special effects, no actual vessel involved.

Yes she exists and the video is of the real vessel in a real operation:

Here is one of her afloat projects, using DP in place of jacking up on a soft bottom location:

Correction; The first video is an animation.

Now that one is real. The other is to me obviously not. Just for a start, the rigging between the crane hook and the loads magically fades into existence as you watch. None of the loads have the slightest sway. No splashing as things enter and leave the water. Bow wave closeup is obvious fake. Etc etc.
