The bubble curtain air provider. ScanTech Offshore support offshore wind farm construction in Europe, UK, Asia and the US with a focus on environment protection. ScanTech support big bubble curtain (BBC) operations with the supply of oil free (class 0) compressed air delivery packages.
The big bubble curtain was developed as a compressed air system for sound absorption in water and especially protects porpoises and seals which use ultrasound as orientation in water.
A ship is typically fitted with a set of ScanTech air compressors to deliver compressed air to a flexible tube with special nozzle openings. The tube is installed on the seabed around the locations where the sound is generated, and the compressed class zero air creates the bubble curtain through the nozzle openings.
