... Abstract. NAUTILUS is a subsea 1.3 MW electrical multiphase pumping unit which operates an helicoaxial multiphase pump with a high speed, directly coupled induction motor fed from an offshore platform mounted voltage inverter through a submarine three phase cable. The system operability...

... will be undertaken in 1993/94 with test of the entire marinized system toward the end of 1994. Whilst the systems developed in this project are purpose built, several items of the technology developed can be utilized in other subsea systems including other subsea multiphase pump station concepts. With the search...

... with a forecast of the possible future applications of multiphase pumping systems. Moreover, a discussion on advantages and limitations of this new technology will be possible, based on the results obtained from the tests of different pumping systems and on the comparison, for several reference cases, of cost...

... of such technologies on technical and economic feasibility. Such technologies include multiphase pumping and subsea separation. Résumé. La situation actuelle des réalisations technologiques dans le domaine de l'exploitation pétrolière en mer est examinée en ce qui concerne les principaux concepts du fonctionnement...
