Brunvoll LowNoise Tunnel Thruster, resiliently mounted with full length double tunnel.

LowNoise Tunnel Thrusters – The optimal solution for improved comfort for crew and passengers, and easy installation for yards. Available in a range from 100 kW to 3.500 kW. Brunvoll pioneered the low noise thruster in 1977. Today, Brunvoll is recognised world wide as the major supplier of effective solutions for thruster noise suppression. Noise levels of 75-88 dB(A) are typical in cabins next to and above conventional tunnel thrusters. Brunvoll’s advanced technology can cut this by up to 15 dB(A). Resiliently mounted with full length double tunnel, results in a noise reduction of 15 to 19 dB(A). For optimal performance Brunvoll takes responsibility for delivering complete systems and for providing support throughout the lifetime; from design, production, installation and commissioning, through daily operation.
