OAKLAND's largest marine terminal operator
plans to retrofit 13 diesel-powered rubber tyre gantry cranes (RTG) with
diesel-electric hybrid engines to reduce air pollution.
The upgrade is expected to eliminate more than 45 tons of exhaust emissions annually at the Port of Oakland, reports the American Journal of Transportation.
The projected cost to upgrade the RTGs is more than US$6 million. The
Bay Area Air Quality Management District this month approved a $5.1
million Community Health Protection Grant Programme / Carl Moyer Program
allocation for the project. The cranes will continue to operate at
SSA's Oakland International Container Terminal in the port.
"We're delighted that SSA is taking a lead role in curbing emissions,"
said Port of Oakland maritime director John Driscoll. "And we're
grateful that their initiative has the support of the Air District.
SSA's hybrid cranes will operate primarily on electricity with diesel
used only for battery charging. The cranes will also regenerate battery
power while lowering containers, which can weigh more than 30 tons.
