Cruise lines embrace IMO MEPC.227(64) 4.2 standard


According to a CLIA (Cruise Lines International Association) survey, 83% of all CLIA member newbuilds will be fitted with sewage treatment systems meeting the highest standards under MEPC.227 (64) Section 4.2 for operation in MARPOL Annex IV Special Areas. At the present time, only the Baltic Sea is a special area according to MARPOL Annex IV. The fact that the vast majority of newbuilds are equipped with sewage treatment systems of this category shows the growing efforts of the cruise industry to reduce their negative impact on the environment.

HAMANN AG offers solutions for cruise ships of all sizes, from the stand-alone retrofit plant to complete sewage systems. All systems are based on our HL-CONT Plus OceanCruise sewage treatment plants certified to IMO MEPC.227.(64) Section 4.2. for all areas of operation including the Baltic Sea and Alaska. These systems combine HAMANN’s proven Dissolved Air Flotation technology (DAF) with Moving Bed Bioreactors (MBBR).
