LOW-NOISE THRUSTERS
Jastrams low-noise transverse thrusters are the best solution for the high demands of the construction and operation of quiet vessels
Proactive noise reduction
The system design and integration of a transverse thruster into the vessel have a significant impact on efficiency and noise emissions. We provide support starting from the design process and noise prognosis for assessment of the overall transverse thruster system in the vessel.
Active noise reduction (ANR)
Counteracting cavitation as one of the main sources of noise in transverse thrusters, you can effectively reduce the volume by 15 dB (A) through active noise reduction. The targeted injection of air reduces noise and vibration in both the vessel and the water.
Passive noise reduction
Structure-borne noise and ambient noise caused by mechanical vibrations can be effectively reduced by installing an elastic foundation for gears, propellers and motors.
BENEFITS
- Elimination of cavitation noise through active noise reduction
- Elimination of the cause of the noise rather than expensive installation of insulation
- Elastically mounted drive unit
- Active noise reduction also for retrofitting of existing systems
- Superior comfort for owners and guests
- Noise reduction for recreation rooms and cabins
- Disturbance-free travel thanks to noise-reduced manoeuvring systems
- Protection of marine environment
- Noise protection near residential areas
