Northport is trialling a new ‘wind rose’ system to reduce the risk of noise nuisance from the port. We will use wind strength and direction to trigger warnings to stevedore companies and other port users loading or discharging from ships between 7pm and 7am.
We have used noise complaint data since mid-2015 to identify the direction from which most complaints have arisen, and the wind state at the time of each complaint. We are also revising the ‘accepted wisdom’ that higher winds carry noise more efficiently, based on research about how rough water scatters noise.
It's a warm, Northport welcome this chilly and blustery winter's evening to HMNZS Te Mana and her crew.
Te Mana called at Northport as POFA (Port of First Arrival) to undertake Customs and MPI clearances. She has arrived back in NZ after completing a major refit in Canada.
