福斯高升压海底多相泵是大型海底深水泵系统的一个组成部分，大型海底深水泵系统用于重油设备，之前由壳牌美洲公司赞助。

    本次福斯与壳牌合作的双螺杆泵，压差可以达到2500psi。输送介质的粘稠度从2cp到2,000cp。福斯双螺杆泵可根据高压的需要，在额定转速1,800转的情况下，每日完成约90000桶的输送。该泵系统的其他设计可以应用于3000psi压力、电源5兆瓦、3000米水深的工况。

    核心技术的完整测试将于2010年年底，在福斯位于荷兰埃滕弗勒尔的高功率测试中心进行。
Flowserve and Shell complete factory testing of twin-screw pumps for high-boost subsea multiphase applications

    24 March 2010
    The high-boost subsea multiphase pump from Flowserve is part of a larger deep-water subsea pumping system initiative focused on heavy oil applications and sponsored by Shell Upstream Americas

    The twin-screw pump from Flowserve, in partnership with Shell, was tested to a differential pressure of 2,500 psi （172 bar）. The performance was mapped with liquid viscosities varying from 2 cp to 2,000 cp. Flowserve has designed the twin-screw pump with a nominal displacement of 90,000 barrels per day at the rated speed of 1,800 rpm for this high-boost requirement. Final design conditions for the pumping system are targeted at 3,000 psi （207 bar） boost pressure in multiphase service with a power in excess of 5 MW and a water depth capability of 3,000 m.

    Full string testing on the core technology will take place later this year at the Flowserve high-power test facility located in Etten Leur, the Netherlands.
