Based on the reports above, speed at sea is not an issue. If there is an azipod issue it seems to be related to slow speed maneuvering (control and turning of the azipods) as when docking.
Now if someone onboard could observe entrance to Barcelona tomorrow and report back, we should know if there is an issue. If tug(s) are required...there is a problem. If the ship can be swung around on its own using the azipods, it would seem the problem has been resolved.
