Automated STS and RTG cranes for the greenfield project

Liebherr Container Cranes has secured the contract to supply four ship-to-shore (STS) cranes and 12 rubber-tyred gantry (RTG) cranes to the Port of Duqm in Oman, with delivery scheduled for late 2022.

The greenfield port development is part of the SEZAD project (Special Economic Zone of Authority at Duqm), centrally located overlooking the Arabian Sea and the Indian Ocean beyond.

The new port is designed to be a multipurpose commercial gateway and one of the largest ports in the region, offering services as an integrated multimodal logistics hub with road, rail and air connections.

The deep-water port and new cranes will allow the port to handle the world’s largest container vessels as it expands its existing cargo and bulk services with container handling.

Gerry Bunyan, managing director – sales for Liebherr Container Cranes, said “These are also our first cabinless and automated cranes in the region and we look forward to seeing the cranes being deployed, and playing the lead role in expanding the services offered by the port.

“The new Liebherr cranes have been designed with the future in mind. Their size and the extensive automation features will ensure that the Port of Duqm will be able to efficiently, safely and predictably handle the world’s largest container vessels for many years to come.”

The STS cranes will feature an outreach of 71 m, a back reach of 18 m and a lift height over rail of 50 m, with a safe working load of 65 tonnes under twinlift spreader.

Supplied without a cabin the cranes will be operated utilising a combination of remote control and automation, which will take care of the majority of the cycle with operator intervention only required when operating below a predefined safe height.

Each Liebherr STS will be connected to its own dedicated ROS. The centrally located remote operation facility will also host the ROS for control of the automated RTGs.

The cabinless RTGs feature automation over the stack with remote control only required for container pick or place from the truck trailers, or for exception handling. Four ROS operators will operate the 12 RTGs.

The diesel-powered RTGs can stack eight containers and a truck lane wide and 1-over-6 containers high.

Data communications in the container yard will be handed by a mesh network. This decentralised system sees multiple access points positioned throughout the yard providing a high speed and stable data network delivering the required latency and high bandwidth communication necessary for remote control.
