the "Sensation" was temporarily detained by the USCG due to alleged fire-safety deficiencies. Apparently some changes to the ship's fire-safety systems were made during the just completed dry-docking. And while, according to Carnival, these were certified by both the USCG and Lloyd's Register (the ship's classification society), the USCG inspectors who checked the ship yesterday did not accept these changes and counted them as violations, resulting in a temporary detention of the ship.
The ship sailed at approx. 11 pm last night.
