"The Port of Durban has had many of the terminals shut over the last 24 hours, however at this stage we have not triggered any contingencies that will cause ships not to call at Durban," said Maersk spokeswoman Kerry Rosser.

South Africa's Durban port has suffered major disruption after days of unrest, and operations have also been badly affected at the Richards Bay port and on a national freight rail line, logistics and freight companies said.

The violence erupted last week in KwaZulu-Natal province, where Durban is located, after the jailing of former president Jacob Zuma but it has rapidly escalated in widespread looting and destruction in several other provinces.

State logistics group Transnet said in a statement that service levels at Durban and Richards Bay were impacted "as the entire supply chain is closed," including roads in and out of ports.

The South African Association of Freight Forwarders told Reuters that port health services at Durban had been closed, effectively preventing vessels from berthing because Covid testing could not be carried out.

"This situation is exacerbated by launch crews also not being available," it said.

Juan Enslin, managing director at Leschaco Group, said his logistics firm had to leave several containers in Durban port for safety reasons.

"We therefore will fall way behind in our delivery schedules. Cargo that has been on the road was also diverted," he said.

On the impact on freight rail, Transnet said force majeure had been declared on the NATCOR rail line that connects Durban to Gauteng province that is home to the country's financial and economic powerhouse, Johannesburg.

Force majeure allows certain terms of an otherwise legally binding agreement to be waived due to unavoidable circumstances.

Transnet said it was deploying resources to avert commercial fuel operations being affected, after being served with a force majeure notice by the SAPREF oil refinery.
