The Air Induced friction Reducing ship COATing (AIRCOAT) project aims to develop a passive air lubrication technology inspired by the Salvinia effect. Applying the AIRCOAT technology to ship-hull surfaces will produce a thin permanent air layer when submerged in water. This will reduce the overall frictional resistance, while acting as a physical barrier between water and the hull surface. In addition to reducing energy consumption, the air barrier will inhibit the attachment of maritime organisms (biofouling).
