Oakland goes hybrid to ‘green’ terminal ops
SSA Marine is to retrofit 13 of the US Port of Oakland’s diesel-powered cranes with diesel-electric hybrid engines to help clean up operations.

The rubber-tyred gantry crane upgrade, which is estimated to cost over US$6m, is forecast to cut over 45 tonnes of exhaust emissions each year at the facility.

John Driscoll, Port of Oakland maritime director, said: “We’re delighted that SSA is taking a lead role in curbing emissions and we’re grateful that their initiative has the support of the Air District.”

According to port estimates, hybrid cranes could lower some pollutants by 99% and could create a 40% drop in greenhouse gas emissions.

The 13 retrofitted hybrid cranes will mainly run on electricity, with diesel used purely for battery-charging and will additionally regenerate battery power while lowering containers, the port said.

The Port of Oakland said that the Bay Area Air Quality Management District (Air District) gave the green light to a $5.1m grant to fund the the project under the Community Health Protection Grant Program/Carl Moyer Memorial Air Quality Standards Attainment Program.

As part of the grant, SSA Marine will also evaluate the feasibility of the cranes and promote the future deployment, of zero-emission cargo handling equipment.

The port said that it could take up to two years to fully retrofit the terminal with the hybrid cranes, partly because the terminal operator needs to finalise a contract with the Air District to get the project moving first.
