South Carolina Ports is equipping its new terminal with 15 hybrid RTGs in a bid to make it one of the greenest in the US.
The Hugh K Leatherman Terminal is now almost fully equipped ahead of welcoming its first cargo ship in March 2021.
“The Leatherman Terminal’s impressive new equipment will provide reliable service to our customers and environmental benefits to the region,” said Jim Newsome, SC Ports CEO.
As part of the construction of the new container terminal, SC Ports said it has undertaken one of the largest environmental and community mitigation packages in South Carolina.
The Leatherman Terminal’s 25 new hybrid RTGs are a big part of SC Ports’ environmental efforts.
The ZPMC-built RTGs will use battery-hybrid technology; a smaller diesel generator charges the batteries and the cranes operate on battery power.
They will run 100% on electric battery power, meaning diesel-only runs when the batteries need to be recharged, which effectively reduces idling time. The batteries, supplied by Corvus Energy, are expected to reduce fuel consumption by around 70% when compared to conventional diesel port cranes.
Regenerative braking energy, which is captured and stored as electricity when a container is lowered, will help reduce the amount of power required from the generator.
Additionally, a smaller generator, which runs fewer total hours, greatly reduces maintenance costs for the hybrid RTGs and significantly lowers fuel consumption, particulate matter, greenhouse gas and other air emissions.
These new cranes now join four RTGs that arrived last month, with an additional six RTGs arriving early next year — making a total of 25 hybrid RTGs.
The Leatherman Terminal’s Phase One will add 700,000 teu of annual throughput capacity to the Port of Charleston when it opens in March.
At full build-out, the three-berth terminal will double SC Ports’ current capacity by adding 2.4 million teu of throughput capacity.
