The analysis covers the technology demands and constraints encountered on screening studies executed for the fields of Marlim, Albacora and Barracuda, as well as an overview of the economic benefits encountered. The paper will focus on the technological demands and constrains identified as well as some considerations about possible alternatives . The demands and constrains identified in the study will provide the industry with some more input to guide the development of the subsea boosting technology, as well as a better understanding of how to apply this new tool on the development of deepwater prospects. The results of the screening study are showing that the subsea boosting systems are a valuable tool to reduce the costs of deepwater developments, provide that the industry could meet the technology demands that are indicated on the study. The cost cutting possibilities through an integration between the "conventional" subsea hardware and the subsea boosting systems and the combination of boosting systems are promising alternatives The subsea boosting systems are a new tool that have -although still under development -recently been added to the tool box of the subsea engineers. [derr[ifying the way to get the most out of it, that is, how to use to the full extent this new technology could help the industry to make the deep water developments profitable. The encouraging economic results found, as well as the demands and constraints raised on the paper will be of use for those trying to apply these technologies in various areas of the world.

A Review on Power Generation for Subsea Loads and the Economic Implication for Future Projects

“…In West Africa, the Pazflor gas-liquid and boosting system was installed in Pazflor field development in Angola. The impact of Subsea boosting on deep water field was identified by (Ribeiro, Camargo & Paulo, 1996), showing results of subsea bosting systems as a reliable tool in cost reduction of subsea deep-water development. As at this time prediction was that about 50 percent of unexploited resources were located in ultra-deep-water areas, which has been the driving force for Petrobr as since its future in the production of oil and gas is linked towards deep water resources.…”

“…The investment cost of capital construction will be lowered by about 40% for the development of offshore oilfield resources if the submarine booster pump station replaces the offshore platform. 2 The multiphase rotodynamic pump is essential for the multiphase blending transportation process. 3,4 It has the rotary rotodynamic pump's structural characteristics and the compressor's structural characteristics, which are attributed to its tapering impeller passage along the streamwise direction.…”
