The 500-mile, 30-inch diameter pipeline will be commissioned shortly with the first flows of crude oil into the line scheduled to commence by the end of this week.

With the modifications of the pipeline, North American producers will have the infrastructure to access more than 4 million barrels per day (BPD) of Gulf Coast refinery demand.

Enterprise initially expects the pipeline to handle 150,000 BPD of capacity, which is expected to increase to more than 400,000 BPD in the first quarter of 2013.

The Seaway system also includes a terminal and distribution network in Texas, which serves the local refineries and in the Houston area including dock facilities at Freeport and Texas City.
