As a result, there is constant pressure by shipping companies to improve turn-around times at ports to reduce idling by ships and containers lying under-utilised on the wharf.

“Greater power in the hands of shippers extends to requiring better communication between terminal operator and ship prior to and during unloading. This is increasingly done through the exchange of EDI or Electronic Data Interchange messages containing details on the cargo manifest and other information,” he says.

To remain competitive as a destination, New Zealand ports are looking for ways to optimise their terminal operations. This includes investment in high-speed cranes with greater lifting capacity and terminal operating systems (TOS) to maximise the productivity of cranes and to make more intelligent decisions about container loading and positioning.

Mr Quinnell adds that while the major driver for terminal optimisation is to meet the needs of their shipping customers, ports also recognise the environmental benefits of reducing the idling time of waiting ships and trucks, cutting diesel fumes and CO2 emissions.
