The ability to transport crude oil without relying on vulnerable shipping routes has become an increasingly important priority for major oil-producing countries. For Saudi Arabia, this has brought renewed attention to one of its most strategic infrastructure assets: the East-West Pipeline.
Saudi Aramco has commenced preliminary engineering work to expand the pipeline's capacity from 7 million to 10 million barrels per day (bpd). The company's President and CEO, Amin Nasser, confirmed the development during its third-quarter earnings call on November 3, 2026, as the kingdom seeks to strengthen its oil export flexibility amid ongoing disruptions around the Strait of Hormuz.
Stretching approximately 1,200 kilometres from Saudi Arabia's eastern oil-producing region to the Red Sea port of Yanbu, the East-West Pipeline provides an alternative route for transporting crude oil to international markets without passing through the Strait of Hormuz.
The existing system can transport up to 7 million barrels daily, with approximately 2 million barrels allocated to refineries on the kingdom's western coast and the remaining capacity available for export. Its strategic importance has become particularly evident during the recent regional conflict, which disrupted shipping through the Strait and affected global oil supply chains.
Strengthening Alternative Export Routes
The proposed expansion is expected to increase the pipeline's transportation capacity by approximately 3 million barrels daily, giving Saudi Arabia greater flexibility in moving crude oil towards international markets.
Beyond the pipeline itself, Aramco is also assessing additional transportation networks, export routes and crude storage facilities to strengthen its ability to maintain supplies during periods of disruption.
The company has indicated that engineering work has started, although further details on the expansion and associated investments are expected following final investment decisions.
The development also reflects a wider shift in Gulf energy infrastructure planning, as countries increasingly consider alternative transportation corridors to reduce their dependence on the Strait of Hormuz.
Why It Matters
The Strait of Hormuz is one of the world's most important oil transit routes, handling a significant share of global petroleum shipments. Disruptions to maritime traffic through the waterway can therefore affect oil availability, transportation costs and international energy prices.
For Saudi Arabia, expanding the East-West Pipeline provides an opportunity to strengthen its ability to move crude oil to Red Sea export terminals, reducing its exposure to disruptions in the Gulf.
The development also highlights the strategic value of pipeline infrastructure beyond its conventional transportation role. In an increasingly uncertain energy environment, alternative pipeline routes are becoming essential to maintaining supply continuity and strengthening national energy security.
