- Multiple loading terminals
- Pipeline networks
- Offshore mooring systems
One of the most important facilities on the island is the Kharg Oil Terminal.
This terminal is capable of loading some of the world’s largest oil tankers, including Very Large Crude Carriers (VLCCs).
At its peak capacity, Kharg Island has handled more than 90% of Iran’s oil exports.
Role in Global Energy Markets
Kharg Island plays a crucial role in global oil supply chains.
Iran is one of the world’s largest oil-producing countries, and much of its crude oil flows through Kharg Island before reaching international markets.
Why Kharg Island Matters Globally
- Major export hub – It handles the majority of Iran’s crude oil shipments.
- Strategic shipping route – Tankers leaving the island pass through critical maritime corridors.
- Energy security – Disruptions here can influence global oil prices.
