VASPS (Vertical Annular Separation and Pumping System) is an innovative concept for two phase subsea separation and pumping system to be installed within a 30'' conductor in a dummy well by conventional drilling and completion technology and equipment. The system is conceived for the exploitation of subsea fields either as subsea separation or as separation and pumping system. Depending on the specific field development, VASPS can produce an enhancement of the well production and an extension of the field life. VASPS can also find application on surface facilities giving an answer to typical problems such us deck space limitations, area classification, dimension, vessel motions. The present paper illustrates the main activities performed and the results achieved in the VASPS development in which a prototype was tested in Agip's Trecate Field in Italy. Field data confirm the viability of the concept both as gas-liquid separator, reaching a separation efficiency higher than 99.5% with inlet liquid flowrate up to 12,000 bpd, and as pumping system. Field tests on various types of level sensors indicate that VASPS level can be measured with commercial components such radar sensors. The VASPS concept and most of the test results on VASPS separator have been presented in previous paper. This paper mainly concerns with the discussion on the VASPS Application and the presentation of the results of the tests on the VASPS Pumping System and level sensors.
