Damen has developed explosion-certified deckhouses for ballast water treatment systems that can withstand wave slamming. The deckhouses can be placed on the open deck of a tanker vessel
Damen notes that as a container construction is not designed to withstand the forces of wave slamming on the open deck of a tanker vessel, it has developed a deckhouse with an 8-mm wall thickness that is able to withstand wave slamming forces. The new deckhouse design fully meets the requirements of the classification societies.
The announcement of the new deckhouse design follows Damen’s pre-filtering barge solution for heavily sedimented rivers and ports.
Each Damen 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 explosion-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 built these deckhouses for tankers with 1,000, 1,500, 2,000 m3 per hour ballast water treatment systems. These deckhouses are constructed at the Damen yards in Europe and China.
Damen states that the deckhouse is an ideal plug and play solution, with the absolute minimum of downtime for the vessel in the repair yard.
Ballast water treatment does not stop with compliance. Industry’s stakeholders discuss the issues in the Ballast Water Treatment Beyond Compliance webinar, which is now available to view.
