This volume provides an international forum for the exchange of the latest and most up-to-date designs for multiphase flow. The development for marginal offshore oil and gas discoveries and/or land-based fields in remote locations have led to significant research aimed at improving our understanding of this complex technology. Better design methods have been developed, not only for transporting multiphase hydrocarbon fluids over long distances, but also for pumping, metering, and processing equipment. Pressure on minimising costs and need to develop smaller, deeper, and more remote fields have continued to spur the application of multiphase technology. However, the uncertainty of adopting new technology will only be overcome with knowledge and expertise, by field use, or by force of circumstances, where it is seen to be the only viable method.
