摘要

This paper describes Kvaerner's prototype subsea multiphase pump system and thernDEMO 2000 development program (current test completion date 2 nd Q2001). Referencernis also made to service proven sub-systems, components and subsea expertisernincorporated into the pump module and system design. Availability and reliabilityrnconsideration together with novel plans for the future is presented.rnThe Subsea Multiphase Pump and motor are packaged into a modular system solutionrnthat is readily adaptable to template and manifold configurations and maximises the usernof existing qualified components and sub-systems. A guidewireless system is adopted andrnKvaerner's design ensures self-alignment upon installation at simple flowbase interfaces,rnmaking it ideal for deepwater applications. Due to the individual 40 tonne weight, andrnmoonpool dimensions, of both flow base and pump module, light monohull vessels canrnbe utilised to execute installation and retrieval.rnThe pump unit is Bornemann twin-screw design, service proven and modified for subsearnuse up to 2000-meter water depth, driven by an oil-filled Loher electric motor thatrnprovides efficient power with corresponding low weight. Some main pump features arernflexible operation covering all gas-liquid ratios together with tolerance for slug flow andrnsome sand. Of particular importance, compared to centrifugal pump designs, the twin-rnscrew volumetric arrangement is able to maintain the pressure boost specificationrnindependent of gas content at the pump inlet, and without an upstream mixing tank.
