Some recent examples:
Energy Transfer Partners said Wednesday it is moving ahead with plans to build a 1,100-mile crude pipeline between North Dakota fields and the oil hub in Patoka, Ill. It could move as much as 320,000 barrels a day to refineries in the Midwest, travel by rail to East Coast plants or be loaded into another pipeline to the Gulf Coast.
North Dakota’s Bakken Oil Fields to Get New Pipelines

Separately this week Enterprise Product Partners L.P. said it hopes to build a 340,000-barrel-a-day line from Stanley, N.D., to the crude oil-storage hub at Cushing, Okla.,
A third line, previously announced by Enbridge Energy Partners was approved Wednesday by North Dakota regulators. The company can begin construction on the 600-mile Sandpiper pipeline as soon as July 1. That $2.6-billion project, scheduled to move oil from North Dakota to Clearbrook, Minn., starting in 2016, will have a capacity of 225,000 barrels of oil a day. From the Clearbrook oil terminal to another oil hub in Superior, Wis., that pipeline will have a bigger capacity of 375,000 barrels a day.
Those are MLPs that own and use the pipelines. Do they manufacture the pipe and construct the line also or do they contract other firms for that?
