MPC owns, leases or has ownership interests in approximately 10,800 miles of crude oil and products pipelines, of which approximately 5,900 miles are owned through MPC’s investments in MPLX. MPC also has partial ownership interests in several pipeline companies. MPC delivered approximately 2.3 million barrels of crude oil and petroleum products daily through its common carrier pipelines in 2016.

MPC has indirect ownership interests in two ocean vessel joint ventures with Crowley through our investment in Crowley Coastal Partners. These joint ventures operate and charter four Jones Act product tankers, most of which are leased to MPC, and own and operate three 750 Series articulated tug barge vessels that are leased to MPC.
