The Trans-Arabian Pipeline (Tapline), once a critical route for Saudi Arabia’s oil exports, is attracting renewed interest amid rising geopolitical risks affecting maritime shipping lanes. Originally commissioned in 1950, the 1,664-kilometer pipeline extended from Saudi Arabia’s oil-rich Eastern Province to the Lebanese port of Sidon, bypassing the Suez Canal to provide a direct overland route to European markets. At its peak, Tapline transported about 30 percent of Saudi Arabia’s crude output.

In recent years, concerns have intensified over vulnerabilities at key maritime chokepoints such as the Strait of Hormuz and shipping routes through the Red Sea, prompting a reassessment of overland alternatives. The pipeline ceased operations in 1990 following regional conflicts, including the Lebanese Civil War and the Gulf War, combined with advancements in maritime transport and the reopening of the Suez Canal.

Saudi Arabia recognized the historical significance of the pipeline in 2019 by designating it the Kingdom’s first industrial heritage site. Beyond its historic role, discussions regarding the pipeline’s potential revival have resurfaced repeatedly, driven by shifts in regional energy dynamics and supply chain concerns. For instance, Jordan weighed the pipeline’s rehabilitation in 2005 to alleviate energy shortages, while European energy disruptions in 2022 reignited debate over alternative routes.

Experts highlight both strategic and economic considerations shaping the feasibility of reactivating Tapline. Economist Jassem Ajaka emphasized that in the current volatile environment, pipelines serve not only as transportation infrastructure but also as geopolitical hedges that foster long-term cooperation among transit countries. He pointed out that elevated insurance costs for shipping through vulnerable maritime routes have sharply increased export expenses, with insurance premiums surging over 400 percent during armed conflicts and reaching as high as $15 per barrel on alternative sea routes. Under stable conditions, pipeline transit could reduce delivery costs to as low as $3 per barrel, potentially undercutting maritime shipping even if insurance expenses partly normalize.

However, some analysts urge caution. Laury Haytayan, an energy policy expert focused on the Middle East and North Africa, highlighted that competitiveness depends on numerous factors including the location of oil production fields, existing infrastructure, and market orientation—Saudi energy exports remain predominantly Asia-bound, which may limit the pipeline’s commercial appeal. Haytayan also noted that Lebanon’s role in a revived energy corridor would likely extend beyond crude transit, potentially encompassing storage or refining capabilities, particularly should regional peace agreements materialize.

Addressing geopolitical challenges, the pipeline’s termination in Sidon lies within a complex regional landscape marked by ongoing tension between Lebanon and Israel. A formal peace treaty between these nations could de-risk transit and financing by eliminating the need for costly government guarantees, yet such developments remain uncertain. Professor Asher Kaufman of the University of Notre Dame underscored the inherent difficulties of securing long-term infrastructure investments that require stable cooperation across multiple, politically volatile states.

Legal experts stress that any revival would necessitate sophisticated governance structures balancing national sovereignty with commercial interests. Attorney Jihad Chidiac suggested a model involving special purpose vehicles (SPVs), wherein states provide land rights and regulatory approvals, while private investors supply capital, supported by binding sovereign agreements, political risk insurance, and arbitration mechanisms. He noted that bilateral investment treaties with stabilization clauses provide some legal safeguards but cannot guarantee physical oil flow during active conflict or force majeure situations.

Ultimately, while the concept of a modernized Trans-Arabian Pipeline offers strategic value amid growing supply chain risks, significant political, economic, and legal obstacles remain. Its revival would require exceptional regional cooperation, stable security conditions, and carefully structured investment frameworks to be commercially viable in today’s complex energy landscape.
