- Four ship to shore container cranes (STS) and twelve rubber tyre gantry cranes (RTG) along with remote operator stations (ROS) to be supplied
- Cabinless cranes will be operated via automation and remote control
- High speed and near zero latency mesh network for remote control of diesel powered RTGs
Liebherr Container Cranes Ltd. announced that they have secured the contract to supply STS and RTGs to the Port of Duqm. The order of four STS and twelve RTGs will be delivered to Oman in late 2022.
The Port of Duqm development is a greenfield project and is part of the ambitious SEZAD project (Special Economic Zone of Authority at Duqm). The facility is centrally located overlooking the Arabian Sea and the Indian Ocean beyond. This new port has been designed to be a world class, multipurpose commercial gateway and is destined to become one of the largest ports in the region. It is being developed into an integrated, multimodal logistics hub and is well connected via road, rail and air. 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.
Automation
The new ship to shore container cranes will be capable of handling the world’s largest container vessels and feature an outreach of 71 m, a back reach of 18 m and a lift height over rail of 50m. The cranes have 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. Automation 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 twelve RTGs.
Mesh Technology
The diesel powered RTGs can stack eight containers and a truck lane wide and one over six 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.
Prepared for the future
Gerry Bunyan, Managing Director – Sales for Liebherr Container Cranes Ltd. said: “Liebherr is very happy to have been awarded this project in Oman. Liebherr has for many years supplied STS and RTG cranes throughout the Middle East, but these will be the first Liebherr container cranes in Oman. 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.”
