The Canyon Express Pipeline System (CEPS) was started up in November 2002 in the Gulf of Mexico, south of Louisiana. It is owned by six oil companies and collects hydrocarbons from ten wells at depths of ~6100, 7100 and 7200 feet.
The flow line system consists of two 12” diameter gas pipelines (“east” and “west”) connected to a header system, which carries the hydrocarbons 57 miles north to a fixed platform, the Canyon Station, in about 500 feet of water. Tankers come into the Canyon Station to fill up and carry the hydrocarbons to refineries. Just west of the “east” flow line is a 2.875” diameter, X-70 line pipe that carries methanol from the station to the header where it is injected to prevent freezing of the hydrocarbons. To the left of the methanol line is a 6” diameter umbilical line containing electrical power and hydraulic lines.
