Study of Quiet-Ship Certifications
March 2019 — British Columbia, Canada
Client: Transport Canada Innovation Centre
An analysis using the ECHO Ship Noise Database to assess the conservativeness of five vessel noise certification societies. A multi-variate linear regression analysis of the database produced a powerful vessel noise model for predicting ship noise based on ship type and operating conditions. A final study examined noise savings that could be achieved if 90% of vessels conformed with thresholds based on median noise emission levels of ECHO measurements.
