Sunoco Logistics Partners LP has received enough binding commitments to enable its Mariner South Pipeline project to proceed. Mariner South will transport export-grade propane and butane from Lone Star NGL LLC‘s storage and fractionation complex in Mont Belvieu, TX, to Sunoco Logistics’ terminal in Nederland, TX. A binding open season continues to solicit additional business (see Shale Daily, March 22). In addition to propane and butane, the pipeline will be available for other natural gas liquids and petroleum products depending on shipper interest, Sunoco Logistics said. It is expected to have initial capacity of 200,000 b/d with the potential for expansion. Operation is expected during the first quarter of 2015.
