Saudi Aramco Pipeline Damage Disrupts Red Sea Oil Exports

Saudi Aramco faces immediate operational constraints after drone attacks damaged the East-West pipeline, a critical artery for bypassing the Strait of Hormuz. The strikes, which occurred on September 10, hit multiple points along the line, including pumping stations 9 and 11, triggering fires and significant infrastructure damage. This event compounds existing logistical pressures as the company navigates a dual threat from Houthi disruptions in the Red Sea and Iranian naval activity in the Gulf.

The East-West system consists of a 5 million barrel-per-day crude line and a 2 million bpd natural gas liquids line, alongside a main gas pipeline serving western industrial facilities. Under normal conditions, this network allows approximately 4.5 million bpd to reach the Red Sea port of Yanbu, effectively circumventing the Strait of Hormuz. The recent damage threatens this capacity, as repairs are estimated to take several weeks, forcing Aramco to rely on spare parts and route around damaged stations at lower flow rates.

Infrastructure Damage Limits Western Export Capacity

Satellite imagery confirms serious damage to the pipeline and at least two pumping stations. The precision of the attacks indicates significant planning and targeting capability, raising concerns about repeated assaults that could exhaust spare parts and repair capacity. While Aramco can likely route around the damaged sites, the reduced flow rates diminish the volume of crude that can be exported via Yanbu, a key alternative to the Gulf blockade.

The threat extends beyond the pipeline to downstream processing. Aramco’s Jazan refinery, located near the Yemen border, was attacked on September 7, halting operations that were scheduled to resume in late August. This refinery is a major supplier of diesel to East Africa, while the Yanbu facilities serve European markets with diesel and jet fuel. With crude stocks potentially depleting before repairs are complete, these refineries face operational stoppages, exacerbating global supply tightness.

Red Sea Disruptions Increase Tanker Logistics Strain

Houthi advances in Yemen have intensified threats to shipping through the Bab al-Mandab strait. Tankers are increasingly using dark transits with transponders off or rerouting via the Suez Canal and Egypt’s SuMed pipeline to the Mediterranean. This forces a longer, more costly voyage around Africa to reach Asian customers. The resulting strain on tanker capacity is compounded by surging US exports to Asia, creating a global logistics bottleneck.

Before the latest attacks, Yanbu was exporting an estimated 3.4 million bpd. The recent disruptions, combined with the seizure of Mayyun Island and advances toward Yemen’s main oilfields, have made the Red Sea route less reliable. The Houthi control of key coastal areas enhances their ability to threaten vessels, further complicating Aramco’s strategy to maintain steady export volumes to major markets.

Dual Threats Squeeze Crude Supply Routes

Saudi Arabia is caught between escalating Houthi threats on the west and Iranian naval activity on the east. While some oil is escaping the Gulf via shuttles and US naval escorts, the overall environment remains volatile. The recent sinking of idle Iranian tankers by the US has intensified Iranian attacks, adding another layer of risk to exports. This dual-front pressure limits Aramco’s ability to optimize its export strategy and maintain stable supply chains.

The situation highlights the vulnerability of Saudi oil infrastructure to asymmetric threats. As repairs continue and security conditions remain fluid, the company must balance the need for rapid infrastructure restoration with the risk of further attacks. The impact on global oil markets is expected to persist, with supply constraints and higher logistics costs driving prices and affecting downstream product availability.
