“This is way better than we thought it would be,” said Ken Larson, crane manager for Seattle-based SSA Terminals. “So far, this is a very successful project.”
The marine terminal, which moves 61 percent of cargo coming through Oakland, is converting 13 rubber-tired gantry cranes from diesel to battery-powered hybrid engines. Since March, three of the 90-foot-tall cranes have been upgraded and are now back in service, resulting in a big drop in the use of fuel. The others will be retrofitted by next June.
“The old engines burned 10 to 12 gallons of diesel an hour; the new ones… about a half-gallon per hour,” explained Larson. “That’s the nuts and bolts of air emission savings right there and we’re astonished by the results.”
