New Technologies in Oil&Gas Rotating Equipment Sector has always remained an interesting topic. Various Technologies that are beneficial to Indian Offshore Oil&Gas sector is covered. Conventional Oil&Gas exploration from shallow depth are slowly getting over and industry is moving towards Deepwater. Technologies deployed in Deepwater and in sub-sea are challenging and at the same time will involve extensive funded research. Technologies like Ultra High Pressure Water Injection Pumps, Multi-Phase Pumps (MPP) and MicroTurbines are discussed. Water injection is used for secondary recovery in Oil&Gas from an aging field and even some of the new fields requires gas lift or water injection right from its inception. Deep water Oil&Gas excavation required very high water injection pressures of the order of more than 300-400 barG. This is very challenging from the perspective of multistage pump design particularly in selection of number of stages and to cater for high axial thrust. In North sea subsea pumping is widely used in remote offshore locations at seabed pumping and for Deepwater offshore wherein building conventional Offshore platform is not lucrative. Multiphase Pumps are being deployed to handle varying Gross fluids (Oil, Water, Gas) with varying Gas Volume Fraction (GVF) and to achieve wider turndown rates. In the power range of 30-200kW, Gas Turbine Generator models are not available. Gas Engine and Diesel Engine models being reciprocating machines have operational/ maintenance intervention issues, diesel handling and logistics leading to increase Operating Expenditure. In this range Micro turbines working on Regenerative Gas Turbine Cycle can be deployed.
