Port noise can often present a challenge for land use planning.  Modelling and practicable noise control measures minimise the potential noise impacts of large scale port operations. Detailed noise measurements on wharf-based equipment such as container cranes and straddle carriers can be carried out to determine noise control strategies and advice can be given on noise management techniques for all aspects of a Port's operation.
