Ships carrying crude oil and petroleum products are limited by size restrictions imposed by several of the main thoroughfares of maritime navigation: the Panama Canal, the Suez Canal, and the Strait of Malacca.

The Panama Canal , an important route connecting the Pacific Ocean to the Caribbean Sea and the Atlantic Ocean, currently has a limited role in global crude and petroleum product transport. The canal’s current size restrictions means smaller vessels, with capacities of approximately 400,000-550,000 barrels of light sweet crude oil, are the only ships that can safely pass through the canal. These ships are referred to as Panamax tankers, and their smaller cargos lead to a higher per-barrel cost. However, the Panama Canal is undergoing an expansion that will allow for the passage of […]
