DESMI Ocean Guard’s containerised BWTS solution successfully 
tested by A.P. Moller - Maersk.

The OxyClean system based on UV and ozone has come through testing in both fresh, brackish and salt water, and Maersk Line concluded it to be an attractive solution, in particular for container ship retrofits.

Per Hother Rasmussen from Maersk Maritime Technology explains: ”We have tested containerized ballast water treatment system plants on two different vessels and we find it a viable way of overcoming space problems in crowded engine rooms as well as it gives the advantage of easy and short installation time, even with the vessel in service. Starting in September 2011, we have tested the DESMI Ocean Guard containerized solution over 7 months on one of our vessels and found that it lived up to our needs and expectations. We are satisfied with the results.”

DESMI Ocean Guard offers the OxyCleanTM system to the market both as a component delivery, skid-mounted or installed in a container. The containerized solution can be delivered with flow rates up to 500 m3/h in a 20' container, and up to 3000 m3/h in a configuration with two 40' containers placed on top of each other. The reason for placing the containers on top of each other is to accommodate the required service height of the filter.

The DESMI Ocean Guard OxyCleanTM ballast water treatment system was type approved by Lloyd’s Register in November 2012. In January 2013 DNV concluded their Safety Assessment of the system and ABS issued a Design Assessment certificate. The OxyCleanTM system is based on mechanical filtration followed by disinfection with a combination of UV and ozone. The system is the first ballast water treatment system on the market that has done successful IMO testing in both fresh, brackish and salt water.
