Hydrate formation is a known flow assurance risk in deepwater flowlines, and remediation via single-sided depressurization presents unique challenges to ensure the mechanical integrity of the subsea infrastructure. This paper describes the gas lift depressurization technique that was developed for hydrate remediation and the engineering study that was conducted to assess the risks.
Keywords: subsea, flowlines, risk assessment
