Reducing underwater radiated noise
A new study reveals that both shipowners and the environment can benefit by reducing underwater radiated noise.

Dr Seyedvahid Vakili and colleagues led a study commissioned by the . It highlighted synergies between the implementation of energy efficiency measures and the reduction of underwater radiated noise (URN).
URN is the sound generated by vessels while operating in the water. Studies have found that URN鈥痝enerated negative impacts on marine life, particularly marine mammals, both in the short and long term.
As the maritime industry moves forward with reducing greenhouse gas emissions to meet net zero emissions by or around 2050, the new study reviews the International Maritime Organization鈥檚 (IMO) initiatives and strategies for decarbonising the shipping industry and identifies the measures and tools available that can contribute to expediting the transition whilst at the same time reducing URN.
Seyedvahid, is a Research Fellow in Sustainability, Energy and Net Zero Emissions in Maritime Industries and part of the Southampton Marine and Maritime Institute (SMMI) . He explains, 鈥淏y adopting certain energy efficiency strategies that also reduce URN, shipowners and the environment can both benefit.
This synergy is key and is a win-win for shipowners as they embrace energy efficiency technologies, our report should help in choices being made for future ship design and operation that reduce the overall environmental impact of shipping and promote sustainable shipping.鈥
Professor of Maritime Fluid Dynamics Stephen Turnock and听Professor of Statistical Signal Processing Paul White were part of the team who produced the report.
