EvoquaWaterTechnologiesprovidesitsSeaCURETM BWTS (ballast water treatment system) operable in all salinities based on proven, widely deployed Chloropac® electrochlorination technology. Based on the vessels characteristics, operational requirements and customers preference Damen BWT experts will select the most appropriate BWT technology for retrofitting. By working with the selected partners, Damen can provide high- quality competitive retrofit packages for all vessel types.


Damen BWT experts use 3D scan techniques to create a customized engineering package. Installation of a BWTS can be done at one of the Damen Shiprepair & Conversion shipyards conveniently located worldwide. Systems can also be installed at a customer selected non-Damen yard or during operation.
