CCCC Shanghai Equipment Engineering (CCCCSEE) and ZPMC have selected Corvus Energy to supply Energy Storage Systems (ESS) for 25 new battery-hybrid Rubber Tyre Gantry (RTG) cranes.
The battery-hybrid RTG cranes will be deployed by the South Carolina Port Authority (SCPA), where they are expected to reduce fuel consumption by up to 65% compared to conventional diesel-electric port cranes.
CCCCSEE will fit two sets of Corvus battery-based ESSs onto each of the 25 RTG manufactured by ZPMC, one of the world’s largest manufacturers of port cranes.
The hybrid cranes can be powered primarily by the Corvus batteries, resulting in an estimated fuel saving of 65% and reduced operating costs, as well as lower greenhouse gases and particulate emissions and noise levels.
Furthermore, system efficiency can be enhanced to 96% by channeling regenerative energy back to the battery during container lowering operations.
“Corvus Energy has definitely shifted the economics and viability of converting diesel port equipment to battery-hybrid electric with their Orca Energy system,” says Gao Jianzhong, Chief Engineer at CCCCSEE.
“Through previous deliveries, Corvus has proven that the performance, durability and reliability of its battery systems is ideally suited to the demands of our port crane applications,” says Jianzhong, reflecting on CCCCSEE’s experience with the 73 Corvus ESSs already delivered and operating.
“Exceeding all requirements and expectations, Corvus ESS technology is a solid cornerstone and part of our future strategy for technological advancement.”
Pradeep Datar, VP Sales Asia, Corvus Energy, also commented: “The design and performance of Corvus Orca ESS support an RTG crane’s aggressive load profiles with a significant reduction in costs.
“With this order, over 90 RTG cranes will be using a Corvus Energy ESS. Corvus technology continues to be the answer for progressive port operators worldwide who seek to increase efficiencies while reducing emissions and the environmental impact of their operations.”
