Quantifying the Effects of Mitigation Measures on North Sea Shipping Noise
bookPart
A generic local shipping lane scenario is developed for a computationally effec-tive study of the effects of mitigation measures to reduce the underwater noise from ship traffic. The scenario is designed using recorded AIS (Automatic Identification System) data for ships passing through a shipping lane north of the Dutch Wadden Islands in January 2020. Assuming that all ships sail at constant speed along a straight shipping lane in a uniform environment, the monthly statistics of the depth averaged soundpressurelevel(SPL)arecalculatedasafunctionofthedistancetotheshippinglane. The calculations are performed using the JOMOPANS-ECHO ship source level model and a parabolic equation sound propagation model. Results are presented for a baseline case (January 2020) and for scenarios in which mitigation measures are applied, such as the application of a maximum speed limit and a maximum ship radiated noise level. The results provide insight in the contribution of various ship types to underwater sound as wellastheeffectivenessofthestudiednoisereductionscenarios.
