Louisiana (St. James & LOOP)

The only US port that fully loads a VLCC. We arrange crude storage, VLCC freight and inspection at LOOP and the St. James river hub.

Offshore buoy mooring with a very large tanker in the open Gulf of Mexico

The Louisiana Offshore Oil Port, about 18 miles south of Grand Isle, is the only US deepwater port where a VLCC can load or discharge a full cargo without lightering. Its three buoys sit in about 115 feet of water, and crude is stored in salt caverns at Clovelly.

Upriver, St. James on the Mississippi is where Light Louisiana Sweet (LLS) is priced, and the river corridor hosts some of the largest US refineries. We arrange storage, VLCC freight and inspection across both.

Two price points

Argus assesses LLS at St. James terminals and Mars, a medium sour grade, at Clovelly and LOOP. Pipelines such as Swordfish connect St. James with Clovelly, so crude can move between river storage and the offshore port.

  • VLCC loading and discharge at LOOP
  • Crude storage at St. James and Clovelly
  • River tanker and barge movements
  • Independent inspection at each transfer

Refineries on the river

The corridor between Baton Rouge and New Orleans hosts several large refineries, all reachable by tanker and barge.
