Who owns LOOP LLC

LOOP LLC - Profile

LOOP LLC owns and runs the Louisiana Offshore Oil Port, the only deepwater crude oil port in the United States able to handle the largest tankers afloat. The terminal sits roughly 18 miles off Port Fourchon in the Gulf of Mexico, where three single point mooring buoys in about 115 feet of water let vessels of up to 700,000 deadweight tons load or discharge crude without entering a harbour. Oil then moves by pipeline to the Clovelly Dome Storage Terminal about 25 miles inland, where eight salt caverns hold around 50 million barrels next to a brine reservoir that keeps the caverns stable, and from there into pipelines serving refineries on the Gulf Coast and in the Midwest. The port began operating in 1981 to land imported crude and now also handles offshore Gulf production and export cargoes. It is a joint venture of subsidiaries of Marathon Petroleum, Shell and Valero, run from Covington, Louisiana.

The disclosed stakes

One row per position. Where a holder reports the same company in two share classes, both rows are shown rather than summed, because the class is part of a position's identity.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.
