It was the technical refinement that finally convinced French shipowner Compagnie Maritime Nantaise (CMN) to choose CleanBallast®.
At the end of April, Bremen-based marine water treatment expert RWO GmbH, a subsidiary of VeoliaWater Solutions & Technologies, signed the contract for CleanBallast® systems with Hyundai Heavy Industries shipyard for two 2,800 lane metre and 903 TEU class RoCon vessels, with an option for a third vessel.
“RWO’s technique of treating ballast water with hydroxyl radicals, in addition to its great experience with water filtration, was in the end the crucial argument to choose RWO as our supplier.
Consciously, we have put emphasis on high-quality equipment for our vessels, and RWO simply offered the best solution,” says Francois Moriceau, Technical Director at Compagnie Maritime Nantaise.
The CleanBallast® units, with a capacity of 500 m³/hr, will be delivered by RWO as skid-mounted systems, which was the yard’s wish, thus reducing installation time at the yard site.
In addition to the CleanBallast® ballast water treatment systems, CMN has decided to complete the water treatment system of the new vessels with further one-stop-shop solutions. For onboard sewage treatment, RWO’sWWT-LC plants will be installed, as well as its oil-water-separators SKIT/SDEB for ensuring best results in treating oily water.
The type-approved CleanBallast® technology is one of the very few that can withstand the uncertainties of the future and has been extensively tested in and designed for real-life conditions, to guarantee a rapid and reliable intake of ballast water. The efficient removal of the sediments also considerably lowers tank-cleaning costs, prevents the loss of valuable load capacities and furthermore leads to fuel savings.
Currently, 38 CleanBallast® systems have already been successfully put into commercial operation. The start-up of most of these units took place in China where they were tested with water from the Yangtze River, one of the most difficult ballast waters in the world.
