Pipe lay (etc) anchor barges do this today.
There are usually six to 8 anchor winches on the vessel. A tug comes to the barge, picks up the anchor and moves it out to some point while the winch unreels. Repeat for other anchors. Winch in to move the vessel.
This is used for precision movement/placement of the barge.
Many vessels use azipods and Dynamic Positioning System (DPS) these days.
But before DPS much of offshore infrastructure was placed by anchor barges.
