Ex-CERTIFIED DECKHOUSE BWTS WITHSTANDS SLAMMING OF WAVES

Wednesday, February 12, 2020 

Damen Shipyards Group has developed a deckhouse-housed Ex-certified Ballast Water Treatment System (BWTS) that can withstand slamming of waves, allowing it to be placed on the open deck of a tanker vessel.

Since a standard container construction is not designed to withstand the forces of wave slamming on the open deck of a tanker vessel.  Damen has developed a deckhouse with an 8mm wall thickness that is able to withstand wave slamming forces, fully meeting the requirements of classification societies.

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 has built these deckhouses for various tankers with 1000, 1500, and 2000 m3/h BWTS. The deckhouses are constructed at the Damen yards in Europe and China. The units are built in locations close to repair yards, allowing ‘plug and play’ installation, with the absolute minimum of downtime for the vessel.
