AIDAluna left the Blohm + Voss shipyard in Hamburg yesterday after extensive maintenance work was carried out from April 26 to May 5, 2014. Work on the cruise ship included among others the installation of the first elements of a comprehensive filter system with which AIDA Cruises is gradually fitting out its fleet. The system for the treatment of exhaust gas emissions, which was developed within the Carnival Group, uses a new technology built in a compact form making it possible to technically integrate all of the main cleaning stages for the first time.
