Mariner East ethane on line soon: MarkWest

OREANDA-NEWS. November 02, 2015. Sunoco Logistics' 70,000 b/d Mariner East I pipeline should begin delivering Marcellus shale ethane soon to the US east coast, committed shipper MarkWest Energy Partners said today.

"Mariner East should be shipping ethane here any day," MarkWest vice president Scott Garner said at the Argus Condensate and Naphtha Markets conference in Houston, Texas.

MarkWest in 2012 signed a 10-year transportation deal to move production from its Houston, Pennsylvania, fractionators to Sunoco's export terminal at Marcus Hook, Pennsylvania. US independent Range Resources, which this summer said ethane transit on the line could start up before October, has a 15-year transportation deal.

The line has been delivering propane for nearly a year.
