Saudi Arabia’s Inland Pipeline Ensures Steady Oil Supply Amid Hormuz Blockage and Yanbu Growth
The ongoing conflict in the Middle East is significantly impacting global energy supplies, raising concerns across international markets. In response to escalating tensions, particularly following disruptions in the Strait of Hormuz due to U.S. and Israeli strikes on Iran, Saudi Arabia has activated its contingency plans. The kingdom is now relying on its East-West pipeline, a strategic infrastructure built in the 1980s, to maintain oil exports and mitigate the crisis’s effects.
Saudi Arabia’s Strategic Response
As the conflict intensifies, Saudi Arabia has swiftly adapted its oil export strategy. The East-West pipeline, which stretches 1,200 kilometers across the Arabian Peninsula, has become crucial for transporting crude oil from the eastern oil fields to the Red Sea port of Yanbu. This route was initially designed as a backup to the Strait of Hormuz, which typically handles about 20 million barrels of oil daily, representing one-fifth of global consumption. With the Strait now under threat, the East-West pipeline is playing a pivotal role in ensuring that Saudi Arabia can continue to supply oil to international markets.
Within hours of the conflict’s escalation, Saudi Arabia began rerouting crude oil through this inland corridor. Yanbu, previously a low-profile industrial port, has emerged as the primary export point, with an increasing number of oil tankers gathering offshore to load shipments. According to Bloomberg ship-tracking data, crude exports from Yanbu have reached an average of 3.66 million barrels over five days, approximately half of the kingdom’s pre-conflict export levels. This rapid adjustment underscores Saudi Arabia’s preparedness for such crises and its ability to maintain oil flows despite regional instability.
The Pipeline’s Historical Significance
The East-West pipeline’s importance is underscored by its historical context. Developed during the Iran-Iraq war in the 1980s, it was intended to reduce reliance on Gulf shipping lanes, which have long been vulnerable to geopolitical tensions. Over the years, the pipeline has undergone expansions and upgrades, increasing its capacity to around 5 million barrels per day. Experts, including Jim Krane from Rice University, have noted that the pipeline’s operation is a strategic advantage for the global economy, allowing Saudi Arabia to continue exporting oil even amid regional disruptions.
Saudi Aramco, the state-owned oil company, has been proactive in managing this transition. As soon as hostilities began, the company reached out to customers to redirect shipments to Yanbu. By March 4, Aramco confirmed that it had ramped up operations along the pipeline, and international buyers quickly began securing cargoes from the port. The scale of this rerouting has been substantial, with at least 25 supertankers heading to Yanbu by March 10. Despite the high costs associated with securing vessels, the number of ships arriving at the port continues to increase, highlighting the urgency of maintaining supply chains.
Yanbu’s Emergence as a Key Export Hub
Historically overshadowed by Saudi Arabia’s eastern Gulf coast ports, Yanbu has now taken center stage in the kingdom’s export operations. The port is handling a significant portion of Saudi Arabia’s oil exports, with refineries and petrochemical plants in the area serving as vital links between domestic production and global markets. The pipeline feeding Yanbu connects major oil fields near Abqaiq on the eastern coast, traversing challenging terrain before reaching the Red Sea.
In addition to crude oil exports, the pipeline also transports around 2 million barrels daily to domestic refineries along the western coast, which continue to produce refined products for export. This dual function enhances the strategic value of the East-West pipeline, ensuring that Saudi Arabia can meet both domestic and international demand even during times of crisis.
Challenges and Risks Ahead
While the East-West pipeline provides a vital alternative route for Saudi oil exports, it is not without risks. Vessels traveling to and from Yanbu must navigate the Bab El-Mandeb Strait, another critical chokepoint that has faced intermittent attacks from Houthi militants. This situation raises concerns about potential disruptions to maritime traffic, which could further impact global oil markets.
The ongoing conflict has already triggered a significant energy shock, with Brent crude prices rising sharply. As the situation evolves, the implications for energy strategies across the Middle East are becoming increasingly apparent. Countries in the region are reassessing their export routes and infrastructure resilience, with Oman positioning its port of Duqm as a regional hub and the United Arab Emirates operating a pipeline to Fujairah that bypasses Hormuz. However, this terminal has also faced threats in recent weeks, highlighting the precarious nature of energy security in the region.
