Maersk Maritime Technology’s Per Hother Rasmussen said: “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 seven 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’s OxyClean ballast water treatment system is based on mechanical filtration followed by disinfection with a combination of UV and ozone. The OxyClean system is offered 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 containers are placed on top of each other to accommodate the required service height of the filter.
The DESMI Ocean Guard OxyClean ballast water treatment system was type approved by Lloyd’s Register in November 2012. In January 2013 DNV concluded its Safety Assessment of the system and ABS issued a Design Assessment certificate.
