Clydeport Greenock comprises the Greenock Ocean Terminal and Clydeport Container Terminal on the southern shore of the Firth of Clyde. It comprises a single quay which extends along the riverside for 372m (1220 feet) with a water depth of 12.6m (41 feet). There is 25,000 sq. m (269,097 sq. feet) of covered space available for cargo storage in sheds, together with 10,000 sq. m (107,639 sq. feet) of outdoor space. The facility occupies reclaimed land from the Bay of Quick, which was the site of the original Greenock Harbour. In 1867, this became the Albert Harbour (now infilled) and the site of Prince's Pier Railway Station, which opened in 1869.
The dock is now owned and operated by Clydeport, part of Peel Ports Plc. Clydeport began in 1966 with the merger of the Clyde Navigation Trust, the Greenock Harbour Trust and the Clyde Lighthouses Trust to form the Clyde Port Authority. This Authority was privatised in 1992, was subject to a management buyout soon after and acquired by Peel Ports in 2003. Clydeport also manages Ardrossan Harbour and King George V Dock in Glasgow.
