Withstanding the waves

Designed specifically for open deck locations, Damen has developed a Ballast Water Treatment Ex-certified deckhouse that is able to withstand the force of wave slamming.

Built with an 8mm thick wall, the BWT Ex meets the requirements of the classification societies and is an ideal ‘plug and play’ solution; ensuring an absolute minimum of downtime during installation for a vessel in a repair yard.

Each deckhouse is delivered as a pre-assembled solution, including the ballast water treatment system with all internal piping and wiring, for easy integration into the vessel. If needed, a booster pump unit can be integrated to ensure sufficient pressure without modifications to the existing ballast pumping system.

The Ex-approved UV reactor, filter and CIP unit are contained within the deckhouse, as is the optional booster pump unit. The lamp drive cabinet, control cabinet and optional booster pump VFD are installed outside the deckhouse and within the vessel’s safe zone.

Damen BWT Ex deckhouses have been built to house 1000/ 1500 /2000 m3/h ballast water treatment systems; constructed right next to the Damen repair and refit yards in Europe and China.
