“The system requires a rigid maintenance programme which keeps it going 24 hours a day, seven days a week. Failure to bypass and achieve a minimum volume of 240 000 tonnes per annum could result in a fine of about R10 million. This is the average quantity of sand required to be bypassed by the system annually. The annual net longshore transport rate within Algoa Bay varies from 240 000 to 320 000 tonnes per year. Both capturing and discharging occur in the wave zones. Sand is captured in a sand trap and pumped via pipelines to a discharge point on the opposite end of the port. This is achieved by pumping the sand from the up drift (west) section of the coast to the down drift (east) section of the coast. This computer-controlled sand bypass system consists of jet pumps which mimic the natural longshore drift of sand along the coast. Mimic the natural longshore drift of sand This means that it is the only port that was subjected to environmental legislation during its entire development, operation and will be during its future development,” Mdodana said. “The Port of Ngqura is the only port in South Africa to have a Record of Decision for its construction and operation. “This is an achievement as we are complying with the Record of Decision (environmental legislation) which stipulated the strict conditions to be adhered to in the development of a port of this nature in an environmentally sensitive area,” said Mandilakhe Mdodana, Environmental Manager for the Port of Ngqura. The Port of Ngqura, the first port in the world to have a fixed jet pump sand bypass system, is meeting its stringent dredging targets of 240 000 tonnes of sand per year, after successfully overcoming challenges.
