 Although the Shell refinery was mothballed in 1989 and later closed, and the north shore facility of Petroplus closed in 2010, as a result of the pipeline petrochemicals traffic still today represents about 50% of the cargo through Teesport, around 26 million tonnes a year.In 1992 the Port Authority of Tees and Hartlepool was privatised, with the original three buyers subsequently reduced to a single owner, Powell Duffryn Plc, in 1995.With traffic out-scaling the port's handling and ship-scale facilities, PD Ports then developed TCT2 in 2002 specifically as a deep-sea cargo quay on top of the site that used to be the original Tees Dock.
