Port of Oakland starts annual dredging to protect 50 feet alongside
THE Port of Oakland said it's nearly a third of the way through its annual dredging programme for 2015, reports the American Journal of Transportation of Plymouth, Massachusetts.
By November, the port plans to scoop 185,000 cubic yards of sediment from 17 deep-water shipping berths. The goal of the US$3.7 million project is to maintain 50-foot (15.2-metre) depths.
"This is one of the least glamorous, but most important jobs a port authority has every year," said port engineering chief Chris Chan.
"Few ports nationwide have the deep-water capability to berth the biggest container vessels, so we need to continually protect that advantage," Mr Chan said.
Vessels capable of carrying up to 14,000 TEU berth at Oakland. These are the largest ships calling at US ports. Berths and approach channels must be 50-feet deep to accommodate them.
The port said it has dredged 45,000 cubic yards of material from six berths since dredging began in August. It will clear another 140,000 yards of material from 11 additional berths.
Dredging season is restricted to this time period to protect endangered fish and fowl. Sediment dredged from Oakland berths is being deposited at the Montezuma Wetlands on Suisun Bay. The 2,400-acre marsh is being restored as a shorebird habitat.
