SATURN Stakeholder Webinar
Our partners from Bureau Veritas, Cetena, CNR, DNV, MARIN, CNR, Naval Group, Quiet Oceans, Sirehna Naval Group and Wartsila, hosted a stakeholder focused webinar on July 8th (15:00-16:30 CET), entitled 'Technical measures to mitigate the impact of ship noise on marine life: Underwater Radiated Noise (URN) and Efficiency Analysis' which was attended by over 50 participants.
The Horizon2020 funded SATURN project has focused on a number of interconnected objectives related to the impact of shipping noise on marine life throughout its project lifecycle. These included:
 Developing standards and methods to measure and assess ship noise,
Quantifying sound exposure of marine mammals and quantifying individual and population-level responses of invertebrates, migratory fish, and marine mammals,
Demonstrating and evaluating decision support tools for Marine Spatial Planning, and
Demonstrating and assessing technical solutions to mitigate ship noise.
Â
In this webinar session our partners shared the approaches and results for technical mitigation solutions for current and future vessels which include a pumpjet as well as a trochoidal propulsor, a retrofit propeller design and the use of air bubbles.Â
The solutions were presented with respect to their costs, efficiency (EEXI/EEDI/CII) and underwater radiated noise. After the presentations conclude, the floor was given to the participants to highlight their readiness to replicate these methods, consider factors relevant to implementing these solutions, and to share their views on which factors may support or constrain early adoption of these actions.
