Magellan Midstream Partners LP and Navigator Energy Services LLC again extended an open season for a light crude oil and condensate pipeline that would connect Magellan's terminals in Cushing, Okla., and Midland, Texas, to Houston.

The open season for the proposed Voyager pipeline will now end Aug. 30 at noon CT, according to a May 31 news release. This is the third time the developers have extended the open season. The original closing date of Jan. 31 was pushed back to March 29 then moved to May 31.

Magellan and Navigator are planning to build 20-inch-diameter pipelines from the Cushing and Midland terminals to Magellan's Frost, Texas, terminal. They would also build a 24-inch-diameter pipeline from Frost to Magellan's East Houston terminal.

Voyager would allow for deliveries to Cushing from the Magellan-operated Saddlehorn pipeline serving the Rockies and Bakken regions, Navigator's Glass Mountain pipeline serving the Midcontinent production area, and other connections within the Cushing oil hub. A proposed Midland, Texas, origin point, which could provide extra supply flexibility from the Permian Basin, was proposed in late March.

Magellan said its Houston crude oil distribution system could also carry product to all refineries in the Houston and Texas City area or to crude oil export facilities, including the Seabrook Logistics LLC joint venture terminal.

Voyager is expected to begin service in early 2021 and would have an initial capacity of up to 400,000 barrels per day, expandable depending on industry demand.

Earlier in May, Magellan CEO, Chairman and President Michael Mears told analysts on a first-quarter earnings call that the developers are hoping the additional origin point in Midland will bring enough shipper commitments to proceed with the Voyager project.
