ABB TechTalks: Meeting the strictest Underwater Radiated Noise (URN) notations with Azipod® propulsion

Recorded webinar


ABB has completed a full-scale validation of the prediction method for URN, which can be efficiently applied to any new project. Discover the latest URN prediction methods and learn from case examples built on full-scale measurements.

Join the conversation with specialists from ABB to find out more about the ways how to reduce URN when operating in environmentally sensitive areas.


  • Review of silent notations by classification societies
  • URN prediction and simulation methods
  • Full-scale method for URN measurements
  • Analysis and case examples:
    • Icebreaker Polaris data comparison between simulation and real operational data
