BC Ferries unveils Long Term Underwater Radiated Noise Mitigation Plan

As a stakeholder in the Salish Sea, BC Ferries considers it a responsibility to understand how its activities may affect whales in general and the southern resident killer whale (SRKW) in particular.

BC Ferries has been an early and active participant in efforts to understand and mitigate the effects of underwater noise. For example, the company engaged scientists to establish baseline measurements of its fleet’s key underwater noise characteristics, including loudness, duration and tonal spectrum relative to modes of operation.

The company now has a long-term plan to mitigate and actively reduce underwater noise. The various actions being undertaken include: choosing hull design to reduce noise from wave making; using alternative propeller styles that are less prone to cavitation; and, placing ship equipment on resilient mounts to reduce structure-borne vibration/noise. The replacement of the older C-Class vessels is another opportunity being ceased to reduce noise and the vibration that may cause it. The ferries being constructed between 2022 and 2030 will be the quietest large vessels that BC Ferries has ever built.
