Georgia cleans up crane act
The Georgia Ports Authority has received grant money from the Environmental Protection Agency and the National Clean Diesel Funding Assistance Program to repower 17 of its older rubber-tyred gantry cranes (RTGs) from TIER I to newer, cleaner TIER III diesel engines.
In addition to significant reduction in emissions, these new diesels will be more fuel efficient, and able to automatically switch between idle (about half of normal operating speed) to higher speeds and back depending on demand.
The RTG repower project will reduce diesel emissions 33.29% or 24,829 tonnes over the lifetime of the 17 cranes, as calculated by the EPA’s Diesel Emissions Quantifier. It will also reduce fuel consumption by 129,200 gallons annually.
