Storage facilities and tank farms provide inventory management capabilities that help balance production and export schedules.

Large storage hubs allow suppliers to:

Manage supply fluctuations
Coordinate vessel loading
Maintain export continuity
Support contractual deliveries

FOB vs CIF Deliveries

Two of the most common international petroleum trade structures are FOB and CIF.

FOB (Free on Board) means the seller delivers the product to the loading port, while the buyer assumes responsibility for freight and insurance.

CIF (Cost, Insurance, and Freight) means the seller arranges transportation and insurance to the destination port.

Examples of petroleum product supply structures utilizing these delivery methods can be found at:

Marine Transportation

Once loaded, crude oil is transported through international shipping routes using tankers of various capacities.

Key maritime corridors include:

Strait of Hormuz
Suez Canal
Panama Canal
Malacca Strait

These routes remain critical to global energy security and supply continuity.
