Underwater noise

PERFORMANCE INDICATOR’S OBJECTIVE:

Reduce underwater noise made by ship operations to reduce impacts to marine mammals.

NOTES:

  • Green Marine recognizes that underwater noise may potentially impact a broader range of aquatic species other than just marine mammals. While the initial objective of this indicator covers marine mammals, future development of this Performance Indicator may expand its scope.
  • Green Marine recognizes that for most ships, under most operational conditions, cavitation is the main source of underwater noise.
  • Applicable only for vessels transiting in salt water.

See below the criteria each ship owner has to fulfill to achieve each level of performance.
