Poseidon Oil Pipeline Company, L.L.C. (“Poseidon”) is a proprietary crude oil pipeline system that was built in response to increased demand for additional crude oil pipeline capacity in the Gulf of Mexico.  Poseidon’s mission is to be the preferred, strategic link for central Gulf of Mexico oil to key markets in Louisiana.  Poseidon intends to provide the combination of flexible, reliable gathering and delivery options and professional, streamlined customer responsiveness that makes Poseidon the preferred pipeline option. 

The western side of the Poseidon system begins at the Garden Banks 72 “A” platform (“GB 72A”) and runs easterly along the Outer Continental Shelf to the Poseidon-owned South Marsh Island 205 “A” platform (“SMI 205A”).  Poseidon operates a bi-directional pipeline between SMI 205A and the Ship Shoal 332 “A” platform (“SS 332A”).  At the current time, this line is flowing in a westerly direction.  At SS 332A, the Poseidon system turns northward and delivers into Shell Pipeline tankage at Houma, Louisiana.  See the System Map page for a complete list of the pipe diameters and mileages for each segment of the Poseidon system.

Poseidon delivers crude oil at the following locations:

1. Into Shell Pipeline Company's ("SPC") tankage at Houma, Louisiana via Poseidon's 24" line from SS 332A,
2. Into connecting carriers at St. James, Louisiana via SPC's 18" line from Houma, Louisiana, and,
3. For barrels on the west side of the Poseidon system and for certain barrels at SS 332A, Poseidon can deliver oil into SPC’s Auger Pipeline via SMI 205A. Refer to the System Map page.

Poseidon is owned 36% by Enterprise GTM Holdings LP, 36% by Shell Oil Products US and 28% by Genesis Energy, L.P., and Enterprise currently serves as the operator.
