First vessel noise certified by ESI

Feb 9, 2021 | News

September 2020, the first ship was ESI noise certified. On the website of DW-ShipConsult, (https://www.dw-sc.de/en/aktuelle/) the following message was published.

“The first vessel that received an ESI-Noise certificate to document the characteristic of its airborne noise emitted during a port visit was MS BARZAN, an 18,800 TEU container vessel of Hapag-Lloyd.

The ESI-Noise certificate is based on the results of a comprehensive noise measurement by DW-ShipConsult. The measurement took place in the Port of Hamburg and followed the official NEPTUNES measurement protocol. According to this protocol, relevant noise sources on board like exhaust gas outlet or ventilation fans are measured directly. Also, noise measurements at given receiver locations are considered. A calculation process summarizes all measurements and considers annoying effects like low-frequency tones. The resulting noise index (ESI-Noise) can be used to apply for port fee discounts in Rotterdam, Hamburg, or other ports”.

For more information, please look into the STC-Maritime-regulations provided by the Hamburg Port Authority.
