ACO Marine to supply wastewater treatment to Royal Canadian Navy ship

GERMAN manufacturer ACO Marine is to supply a complete wastewater management package for the converted 23,800 dwt, 1,702-TEU Asterix deployed under the Royal Canadian Navy's (RCN) 'Project Resolve" for humanitarian assistance and disaster relief (HADR) operations, with a crew of up to 150 and extra emergency accommodation capacity for 350. 

The retrofit is intended to bring Resolve's current sewage treatment facilities up-to-date, in order to comply with the latest IMO regulation, MEPC 227(64).



"Quite a challenge," said managing director Mark Beavis, "to fit an advanced black and grey water treatment system capable of meeting an increased loading requirements for a total crew and hospital staff of up to 450 persons on what was once a containership made for a challenging retrofit solution."



Under the terms of the agreement, ACO Marine will supply, install and commission two MEPC 227(64)-compliant Maripur NF-150 advanced membrane bioreactor wastewater treatment plants with integrated black water vacuum collection systems. 



Lipator NS7 advanced grease separators for the pre-treatment of galley water and grey water transfer and aeration systems for the AOR's collecting tanks also form part of the package. Operation and maintenance training will also be provided.



"The Maripur NF-150s are future-proofed for compliance with MARPOL regulations and provide improved operational flexibility, reduced in-service operating costs and negate the risk of environmental fines for pollution discharge in sensitive marine environments," said Mr Beavis.



The retrofit is to be carried out at the Chantier Davie Canada shipyard in Levis, Quebec, this October, with the converted vessel due to enter service the following summer. 



The LR-classed vessel will serve the RCN until two newbuild Queenstown-class auxiliary ships, HMCS Queenstown and HMCS Chateauguay, enter service in 2021.
