The modern dock operated by Shell Oil Company as part of the Wood River Refinery in Illinois was designed to include features which minimize the possibility of oil spills. The dock is located on the Mississippi River near St. Louis. It is comprised of four floating sections and is designed to load and unload barges only. Solid pipe loading arms are used to make the connections between the floating dock manifold and the barge header. The primary loading valves on the floats can be operated manually or electrically from a local station or remotely from the dock control center. Each floating dock is equipped with a drainage system to prevent spillage into the river. An intercom system provides communication between the dock control center and the loading areas. The dock operator is also in direct radio and telephone contact with refinery operating personnel responsible for the transfer of oil. Operation of this facility has met the criteria of efficient operation and protection against spills.
