May well be the wire is run off the drumm to clear any bad overriding turns on the drum,
which jam when the tow is being taken up by the ship.

As the tugs shown are "twins" or sister-tugs, maybe it's a case of verifying that the power of each is equal, after, say, a mechanical problem in one of them. They would not have to go to full power (which would be extremely dangerous in case of the line breaking) just a set rpm &/or pitch setting to see if one was under-performing......
Just a thought......
(I rather doubt it is a case of Big Boys With Their Toys as some seem to be suggesting!)

ONE OTHER THOUGHT ON THIS ONE

it is may be not a spooling off but a spooling on.
That more tight the lower layer on the drum is, that harder it is for the upper layers to squeeze in and hinder the wire when spooling out is quickly needed. That would make sense.
that is otherwise only possible to let it run around a bollard on deck, not likely with a new tow wire rope

[Oldkayaker]

OK, good point, a bollard test, to be accurate, would need to have one end attached to a permanent, stationary point.

Must be a line stretching operation as I originally guessed.

We often to this if we manage to bury the rope into the layers and can't get it out on board ourselves (limited space and crap placement of bitts mean its sometimes difficult to do it onboard).
So we hook up to another tug, and let her pull it out.

Also, as mentioned before, to get a tight stow on a line the other tug is used to keep tension on it.

Thank You Ancient Mariner,
That makes sense to me......Space: The Final Frontier.
