Damen Air Cavity System (DACS)
Patented air lubrication system that creates air cavities under flat-bottomed hulls, with fuel reductions of up to 15% verified by RINA and Lloyd’s Register.
Description
The Damen Air Cavity System (DACS) is a patented air lubrication system that generates air cushions between the hull and the water under the flat bottom area of a ship, reducing resistance, fuel consumption and emissions. Air is injected behind a small cavitator that separates the water flow from the hull, while longitudinal skegs keep the air from escaping sideways. A series of subsequent cavities maximises coverage of the flat bottom. Because the compressors only need to overcome the hydrostatic pressure from the draught, power demand is lower than with first-generation bubble systems.
Key features
- Fuel reduction of up to 15%, verified by RINA and Lloyd's Register
- Cavitator and longitudinal skegs retain the air layer under the hull
- Lower compressor power demand than bubble-type systems
- CII compliant
- Can be installed during a scheduled docking
Applications
- Ships with a low Froude number and a flat-bottomed hull
