The Ship Shoal system consists of a 22-inch sour pipeline and 19-inch sweet crude pipeline that delivers oil to the Gibson terminal in in Louisiana, which then sends the crude to the crude terminal at St. James, Louisiana. The capacity is 390,000 barrels per day. It gathers oil from the following pipelines: Tarpon/Central Gulf Gathering, Auger Crude Oil Pipeline, Whitecap/Cougar, and Plains, and delivers to the following terminals: St. James Capline, ExxonMobil, Sugarland, Nustar, and Plains, as well as to the Red Stick pipeline.[1]

The system first began operating in 1973.[5]

Expansion projects


In 1997, Shell expanded the capacity of the pipeline and added an additional 90,000 bpd.[3] According to the Houston Business Journal:

"Ship Shoal Pipeline Co. plans to expand its pipeline system in southern Louisiana, increasing the capacity of the crude oil line from 310,000 barrels per day to 400,000. The expansion project will include installation of new pumping equipment at Shell Pipe Line Corp.'s Gibson, La. terminal and construction of a 13-mile stretch of 20-inch pipeline. Shell Pipe Line operates the Ship Shoal Pipeline System and owns a 42.5 percent interest in the venture. Unocal Pipeline Co. owns 40 percent and Paloma Pipe Line Co. owns 17.5 percent."

The expansion is presumed to have begun operating as of 1997.
