Quieter sailing means better sleep, improving the alertness and efficiency of the crew. Passengers enjoy a new degree of comfort.
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). Combined with other measures, noise reductions of up to 20-25 dB(A) have been verified.
The ultimate in quiet manoeuvring adds a new dimension of comfort and pleasure to the voyage - much appreciated by discerning travellers. Noisy thrusters would create a harsh, disturbing contrast. That's why major cruiseship owners insist on low noise thrusters - and Brunvoll's noise supression leads the field.
Typical shiptypes where noise reduction is of utmost importance are such as cruise liners, megayachts, diving support vessels and other sophisticated offshore service and research vessels.
The figures above show typical noise levels in a cabin 3 - 4 decks above the thruster room.
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.
