The portable pumping units weighed 125 tons each. They arrived by sea, were hauled to their places on the line on giant trailers.

portable gas turbine pumping unit, and permits the line to continue to operate safely.
    From Shu'bah, Barrel X continues westward through alternate base stations and portable gas turbine driven pumping units at Rafha, 'Uwaigilah, Badanah, and Jalamid, 677 kilometers to Turaif, the most westerly operating location in Saudi Arabia.

UNIQUE HYDRAULIC PUMP

    Turaif has three electric-motor driven centrifugal pumps, and two permanently mounted 5,000horsepower gas-turbine driven centrifugal pumps, instead of the six diesel-driven pumps used at the other three main pump stations. Turaif also has another Tapline innovation: a booster pump driven by a part of the hydraulic power supplied by the main gasturbine driven pumps. Here is how it works:
    After the oil leaves the main gas turbine driven pumping units at high pressure, a small part of it is diverted into the hydraulic turbine. This turbine is similar to a centrifugal pump, except that highpressure oil is forced through it, causing it to rotate. The rotation of the hydraulic turbine then drives a conventional centrifugal booster pump, which boosts the main oil stream to the suction pressure required for satisfactory operation of the high speed gas-turbine driven pumps.
    When Barrel X leaves Turaif, it moves 165 kilometers to Qaryatain, Jordan, where it is boosted by a permanently mounted 5,000-horsepower gas turbine unit. This unit is controlled by radio from Turaif. It functions in the same manner as the units at Shu'bah, 'Uwaigilah and Jalamid, but the pumping unit and controls are installed in a conventional building instead of in portable vans.
