The Problem with Reducing Underwater Radiated Noise

If the global commercial fleet reduced its speed by 10%, it would reduce underwater radiated noise by 40%, but nothing’s ever that simple.The main thing holding the shipping industry back from reducing its underwater radiated noise (URN) is not a lack of appropriate technology. It’s argued that many of the technologies being implemented today to reduce fuel consumption also reduce noise. So, the noise reductions could essentially come at no net cost to the shipowner, but there’s a lack of regulation and a lack of targeted incentives…

KOTUG Canada, GIT Team to Cut Underwater Radiated Noise

KOTUG Canada has applied "revolutionary non-toxic noise reduction coatings" to the hull of one of its vessels, the K.J. Gardner.KOTUG Canada used Graphite Innovation and Technologies' (GIT) XGIT-URN coating to help reduce underwater radiated noise emitted from the ship’s hull and the vibrations that disturb marine life.K.J. Gardner is the first of three vessels using the GIT applications in support of KOTUG Canada’s mission to reduce the impact on the environment, specifically related to the reduction of noise that potentially disturbs aquatic life in the Salish Sea and adjacent waters.
