During a recent guided tour led by Timothy Keit, business development representative at Transnet Port Terminals( TPT), industry stakeholders were given an in-depth look into the complex logistics, infrastructure and operational challenges shaping the future of this port. Keit’ s presentation offered insight into the real-time movement of goods, the technologies enabling container |

management and the delicate balance between infrastructure limitations and strategic growth.
The journey through the port begins at the terminal entry gate, where drivers input their NaTIS code – a critical part of the port’ s logistical infrastructure. This code instructs drivers on which RTZ( Restricted Transfer Zone) to proceed to, simplifying internal navigation. An RTZ is a designated area within a port or terminal where specific controls and restrictions apply to the transfer of cargo, containers or passengers. These zones are often set up to enhance safety, security or environmental protection, and to manage customs or regulatory requirements. Access to an RTZ is usually limited to authorised personnel, and operations within the RTZ may be subject to stricter monitoring or documentation. With multiple zones such as North, South and East towers, the system ensures efficient allocation of containers.

There are roughly 500 active truck slots across the two terminals, each serving private drivers who transport goods in and out of the facility. As the drivers move toward the RTZs, they are directed to container stack areas or reefer yards based on container type and priority.
Durban Port plays a key role in the cold chain logistics essential to South Africa’ s agricultural exports. The port features permanent reefer yards as well as temporary ones during peak seasons. Reefer( refrigerated) containers – numbering around 3 600 units – are used to store perishable cargo like citrus, avocados and frozen meats.
A challenge that arises post-peak is the handling of empty reefer containers. After exports peak, often 1 000 empty reefers are returned and must be managed. Co-ordination among shipping lines, cold storage operators and Transnet’ s Cargo Terminal Agency( CTA) becomes crucial.

Forecasting from growers and exporters helps determine the volume of containers required in the next season, and depending on demand, shipping lines may dispatch reefer vessels from as far as the Far East.
RAIL OPERATIONS AND CONTAINER FLOW
The Rail Mounted Gantry( RMG) yard plays a vital role in inland distribution. The yard accommodates trains of up to 100 wagons( 100 TEUs) and is supported by three rail lines. Trains are often broken into smaller blocks for unloading using RMG cranes, enhancing turnaround times.
While straddle carriers used to be the primary mode of transport within the yard, they are increasingly being replaced by haulers for longer-distance movement within the terminal. Straddle carriers, though agile, are limited in speed and more prone to accidents over longer distances.
