HOMEHOMEPoseidon is a propriety crude oil pipeline system operating in the Gulf of Mexico. Poseidon, owned 36% by Enterprise Products Partners, 36% by Shell Pipeline Co. and 28% by Marathon Oil Company, is a major sour crude oil pipeline system that was built in response to an increased demand for additional sour crude oil pipeline capacity in the Central Gulf. Poseidon consists of:
approximately 117 miles of 16 diameter pipeline extending in an easterly direction from Enterprise 50%-owned platform located at Garden Blanks Block 72 to Poseidon owned South Marsh Island 205 platform and a 20-inch pipeline extending to the Enterprise platform located Ship Shoal Block 332,
approximately 122 miles of 24-inch
diameter pipeline extending in a northerly direction from the Ship Shoal
Block 332 platform to Houma, Louisiana and
approximately 28 miles of 16-inch diameter pipeline extending southeasterly to Ewing Bank Block 873.
In July 1998, Poseidon completed a 17-mile extension of 16-inch pipeline from Garden Blanks Block 260 to South Marsh Island Block 205.
