Revised Guidelines for the Reduction of Underwater Radiated Noise from Shipping to Address Adverse Impacts on Marine Life

These guidelines from the International Maritime Organisation were created to provide an overview of approaches applicable to designers, shipbuilders, and ship operators for reducing the underwater radiated noise (URN) of any given ship, as well as to assist relevant stakeholders in establishing mechanisms and programmes through which noise reduction efforts can be realised. It provides information on URN management planning, URN reduction approaches, evaluation and monitoring, and more.
