LOWNOISER Webinar: Analytical Modelling Approaches for Underwater Noise Reduction in Shipping
As part of the Horizon Europe project LOWNOISER – Lowering Underwater Noise Radiation from Waterborne Transport, this webinar will present practical demonstrator cases showing how analytical modelling methods can be adopted to evaluate the effectiveness of abatement solutions for new build ships and retrofits.
The webinar will focus on real industrial applications developed by LOWNOISER partners. Through concrete examples, participants will gain insight into how underwater noise challenges can be analysed and addressed at a technical level using predictive engineering tools and operational data.
The session will include presentations from partners directly involved in the demonstrator activities, covering topics such as:
- Bevel gear noise reduction on board MS Havila Capella
Optimisation of underwater spiral bevel gear microgeometry to reduce tonal noise emissions using analytical excitation and transfer-path modelling. - Air Lubrication System (ALS) on Vertom Joy
Assessment of underwater noise reduction potential through reduced propulsion power demand and acoustic damping effects from air lubrication. - Operational monitoring on Montesperanza
Use of onboard monitoring systems and operational data to support underwater noise assessment and prediction. - Engine mount optimisation and operational monitoring on Fridtjof Nansen
Investigation of vibration isolation measures combined with monitoring-based analytical evaluation.
The webinar will highlight how modelling frameworks such as PIANO and other analytical methods can be used to estimate the abatement potential of different technologies before and after implementation.
The event is intended for ship designers, shipowners, technology providers, researchers, classification societies, ports, policymakers, and other stakeholders interested in sustainable shipping and underwater radiated noise reduction.
