<p>A slug mitigation system for subsea pipelines includes a riser (11) located between a low level and an upper (above sea-) level of a pipeline, where an inline separator (14), e.g. an ISEP, is located upstream of a first stage separator (12). A jet pump 21 is located at the upper level of the pipeline and is configured to utilise high pressure fluid output from the inline separator. Preferably a throttling valve or fixed restriction is located downstream or upstream in series with the inline separator (14). The slug mitigation system may also include a cyclonic separator downstream of the in-line separator (14). The system may reduce the effect of slugging on a pipeline riser/pipeline system for offshore oil and gas use.</p> |
