... 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 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...
