thanks. So the surveys due this August will likely be carried out "in water" as the classification societies say (i.e. during regular port calls). By February 14th, 2008 the ship's Azipods will have to be surveyed. I guess that the only way to do that is in drydock so the date you mentioned makes sense in that respect.
As for "Carnival Liberty", she must undergo a "Bottom - Dry Condition" survey between January and July, 2008.
