Georgia Ports Authority installs four Konecranes hybrid electric RTGs

  20.12.2012    

The Georgia Ports Authority has put into operation its first four electric rubber-tyre gantry cranes (ERTG), making the GPA the first in North America to introduce this cleaner machine which is said to reduce fuel costs 95 per cent.
"This transition to electrified RTGs is an important milestone for the GPA and our industry," said GPA executive director Curtis Foltz. "This project is the latest in a series of GPA initiatives designed to increase the productivity and capacity of the port in environmentally responsible ways."
The new ERTG system was developed with the help of partners Konecranes, Conductix-Wampfler and Georgia Power, which provided the cranes, the new power system and the electrical infrastructure.
Through efforts such as electrifying ship-to-shore cranes and refrigerated container racks, the Port of Savannah avoids the use of more than 5.4 million gallons of diesel annually. The new cranes will further reduce the GPA's fuel demand, a statement from the port authority said.
While relying on cleaner, shore-based power to handle containers, the ERTGs feature the ability to automatically switch to diesel generators when moving from stack to stack. All functions are controlled by the ERTG crane operator.
Mr Foltz said long-term plans call for retrofitting the Garden City Terminal's fleet of diesel-powered RTGs to use shore power via retractable arms which will link to a conductor rail system, bringing the total number of ERTGs to 169 by 2022. Repowering the RTGs will be a multi-year initiative, requiring new cranes to be ordered with electric power capabilities, and some older cranes to be retrofitted, according to the Shipping Gazette.
