First Rim-Drive Thruster Achieves Silent-E Notation
Kongsberg Maritime’s rim-drive azimuth thruster has achieved Silent-E notation from DNV, the first of its kind to receive this certification.Installed on the new commissioning service operation vessel (CSOV) Norwind Hurricane and its sister vessels, the thruster demonstrated exceptional performance in reducing underwater noise pollution during a recent trial.To assess the noise levels of the Norwind Hurricane, an extensive underwater noise study was conducted using hydrophones placed on the seabed.
Kongsberg Maritime Adds to Rim Drive Azimuth Thruster Range
Kongsberg Maritime has launched a new Rim-drive Azimuth Thruster, the RD-AZ-2300.The RD-AZ-2300, with a propeller diameter of 2,300mm, sits between the existing RD-AZ-1900 and RD-AZ-2600 models and is suited for vessels operating in demanding environments such as offshore wind farms, where precise maneuverability and low noise levels are crucial.In adherence to DNV’s Silent R classification, the RD-AZ-2300 also provides significant advantages to underwater research vessels by reducing underwater radiated noise (URN) below sea levels, says Kongsberg Maritime.

Schottel Touts Noise Signature of Transverse Thruster
The Schottel TransverseThruster with elastically mounted well installation reduces sound emissions by up to 11 dB, according to the manufacturer, with the added bonus of minimized underwater noise, too. The particularly low-vibration design of the STT is suitable for vessels of all types and sizes.In addition to reduced sound generation from the propeller and its surrounding structure, the well installation brings another advantage: since the propulsion unit is not welded to the vessel structure, flexible access to the unit is possible.
