Project Details

Owner: Port of Oakland

Contract value: $17,246,655


The Shore Power System Construction Project for the Port of Oakland at Berths 25, 35, 37, 55, 59, and 68 is being constructed to comply with the new California Air Resources Board (CARB) requirements for vessel shipping traffic. CARB requires ships to use shore power instead of onboard diesel generators while they are docked. Shimmick Construction is installing a shore to ship power system at each berth to provide that power source.

The work consists of procuring and installing new electrical distribution equipment including 2 each 12.47kV switchgear assemblies, 6 each 7,500kVA transformers, 6 each 6.6kV switchgear assemblies, and 17 each 7.2kV shore to ship power enclosure receptacles. The backbone raceway work connecting the electrical equipment consists of procuring and installing 14,945 ft of underground PVC conduit, 42,570 ft of under wharf fiberglass conduit, 24,318 ft of 15kV-750 kcmil medium voltage cable, 86,680 ft of 8kV-350 kcmil medium voltage cable, and 190,225 ft of 600V-THHN building wire.
