ACO MARINE Grease Separation Systems for AIDA Cruise Liners
22 November 2007
ACO Marine, part of the ACO Group of companies, received enquiries for galley water systems from the shipyard Jos L Meyer GmbH in Pappenburg for their new AIDA cruise liner (3,100 people on board, 250 m3/day of galley water).
To meet the customer requirement ACO Marine offered their automated grease separator, the LIPATOMAT NS15. The shipyard recognised the LIPATOMAT's unique features and in particular that, unlike most other separators, the LIPATOMAT range does not need to be fully discharged at regular intervals. Grease and/or sediments are separated within the process and then disposed of separately without interrupting the operation of the unit. This allows separate handling of grease and sediments on board and greatly reduces the overall space requirement. Grease on cruise liners is usually burned in an incinerator with the sediments being stored separately prior to discharge ashore.
The LIPATOMAT system usually discharges grease, sediments and treated water on a gravity flow-through principle but for AIDA it was necessary to pump these waste streams to independent tanks against a 3-5m discharge head. To meet this requirement ACO Marine developed a bespoke solution comprising the automated LIPATOMAT 15 grease separator, a pumping station for treated galley water connected to an outlet from the grease separator and two progressive cavity pumps directly connected to the grease and sediment outlets. All components were mounted on a common frame, piped and wired complete with integrated system control panel.
This compact modular solution greatly simplified the shipyard's installation of the grease separation system on board the vessel. ACO Marine have been working closely with the shipyard for a number of years and received orders from Jos L Meyer GmbH for this grease separation solution on board the three AIDA class of vessels with the last shipset being delivered in October 2007. ACO Marine is concluding discussions with the shipyard for further vessels in the class after the yard received new orders.
