LR launches industry first airborne noise notation for ships in ports

摘要

Lloyd's Register (LR) has released a new airborne noise emission notation (ABN) and ShipRight procedure to meet increasing demand for a standard and methodology to control airborne noise emissions from ships. The new notation defines a set of limit levels for airborne noise emission from ships. This enables ports to better monitor overall noise levels from ship calls. It will assist ports in determining which and how many ships can access the most noise sensitive areas of the port. It will also allow ports to specify ships require a certain ABN notation to stay in a noise sensitive area of the port, for example those locations close to residential areas.
