Queen Elizabeth II Dock

From Wikipedia, the free encyclopedia

Queen Elizabeth II Dock is a dock situated on the River Mersey at Eastham, on the Wirral Peninsula, England.

Construction of the dock began in 1949, adjacent to the entrance of the Manchester Ship Canal at Eastham Locks and opening directly onto the river. The dock was built to provide berthing facilities for large tankers that could not be accommodated on the existing canal due to size. Simultaneously, an oil storage facility was built nearby and pipelines laid to link the dock and storage facility to the Stanlow Oil Refinery near Ellesmere Port. The Queen Elizabeth II Dock became operational on 19th January 1954. ^[1] ^[2]

The lock chamber measures 807 x 100 feet in size with a water depth of 40 feet. Two steel gates are located at either end of the lock, with a further gate one third of the way along from the Mersey entrance. These gates open by retracting into the dock wall. The dock itself was constructed with four berths, each capable of handling up to 30,000 tonnes of petroleum. ^[1]

Subsequent increases in tanker size since the dock was built has meant that larger vessels use the Tranmere Oil Terminal and at offshore berths at Anglesey in North Wales. ^[1] ^[2]
