LowNoise
Tunnel Thrusters
•
The trend is towards low-noise thrusters,
and Brunvoll has shown the way
•
Thruster noise represents a major problem
for crews
•
The stress and discomfort it causes may
threaten both performance and safety on
board
•
Quieter sailing means better sleep,
improving the alertness and efficiency of
the crew. Passengers enjoy a new degree
of comfort
•
Brunvoll introduced the low-noise thruster
in 1977. Through several technological
generations we have refned our patented
solutions into a proven concept, reducing
noise by up to 15 dB(A)
•
We supply 8 out of 10 thruster units in the
demanding low-noise niche to ships including
cruiseliners, mega yacht, passenger ferries,
research vessels, and offshore support vessels
with intensive use of DP
The ultimate solution,
Brunvoll RDT resiliently
mounted
Brunvoll’s innovative
Rim-Driven Thruster design
combined with resilient mounting
provides the ultimate solution in
noise reduction and low vibration
The Brunvoll LowNoise Tunnel Thruster design, Resiliently Mounted with
full length double tunnel, results in a noise reduction of 11 to 15 dB(A).
This design is mainly used on cruise liners, super yachts, passenger ships,
research- and offshore vessels where extensive noise suppression is
necessary.
