Routing of wells, risers and other systems at surface is yet another control that often needs to be considered. As such, a variety of optimizers were applied, each...

... management systems have allowed longer tie-back distance. Cost-effective mooring systems for large FPSO, flexible flow-lines and catenary risers have enabled floating system of FLNG size to be seriously considered. However, it is the advance of floating LNG technologies that have evolved over the past 20...

... integrity issues when they impact bends. In flowline-riser systems, riser-induced slugging can lead to large slugs, especially in deepwater systems. These can usually not be contained in a platform-based separator. In such cases gas lift and conventional choking are often used to mitigate slugging...

... Abstract An experimental study of severe slugging suppression utilizing a combination of surfactants and gas-lift was conducted using a facility consisting of a 3-in. ID, 65 ft long, -3° inclined flow line followed by a 45 ft long vertical riser system. Air and water were used as fluids...

... Abstract In the last few decades, flexible risers have increasingly been used in the offshore oil and gas industry. In gas applications these risers can generate high amplitude tonal pressure fluctuations when the gas velocity reaches a threshold value. The resulting pressure fluctuations can...
