riyadh, April 9 -- Saudi Arabia's oil pipeline to the Red Sea was hit by a drone attack on Wednesday afternoon, according to a person familiar with the matter. The damage is still being assessed, the person said. Saudi Aramco declined to comment. The East-West pipeline has served as a vital lifeline to getting Saudi oil to global markets after the Strait of Hormuz was effectively closed by the conflict in the Middle East. The attack was first reported by the FT. The East-West pipeline that circumvents the Strait of Hormuz is pumping oil at its full capacity of 7 million barrels a day, according to a person familiar with the matter. The technical milestone is the culmination of the kingdom's longstanding contingency plan for keeping its oil flowing after the effective closure of their main export route. Flotillas of tankers have been redirected to the Red Sea port of Yanbu to collect the oil, providing an important lifeline for global supply. Crude exports via Yanbu have now reached about 5 million barrels a day and the kingdom is also exporting 700,000 to 900,000 barrels a day of refined products, according to the person familiar with the Saudi oil industry. Of the 7 million barrels a day that go through the pipeline, 2 million are destined for Saudi refineries. The Yanbu route only partly offsets the hit to supply from shutting Hormuz, through which about 15 million barrels a day of crude shipments passed before the war. But the bypass is one reason oil prices haven't reached the crisis-level highs of previous supply shocks. With Yemen's Houthis now saying they are entering the war, the concern for the oil market will be that the Red Sea becomes a new front in the conflict. While the Houthis have not given any indication they would attack tankers going through the Red Sea and Bab El-Mandeb strait, they have previously threatened shipping in the area with drones and missiles. Saudi Arabia, which has a historical role as the world's oil supplier of last resort and nurtures a reputation for reliability, had prepared for decades for the worst-case scenario of Hormuz closing....
