title = "Risk-based flow assurance design for natural gas hydrate production systems",
abstract = "Transport in subsea gas gathering networks of hydrocarbons liberated from natural hydrate deposits poses many of the same risks as faced in more traditional hydrocarbon production. There is an inherent need to ensure that these fluids do not recombine into hydrates within the flow network, a familiar problem in flow assurance. This paper describes a risk based approach to assessing hydrate formation in the transport flowline of a produced hydrate deposit. The bathymetry is typical of those found off the Australian coast, with fluid properties as expected for a methane rich natural hydrate deposit. To fully assess the 'risk' of hydrate formation, probabilistic analysis based on Monte-Carlo simulation of the blowdown pressure and nucleation temperature are performed. This is coupled with targeted transient analysis of the severity of hydrate formation using a new plugin for OLGA{\textregistered}, which focuses on the mechanics of hydrate formation in gas dominant systems.",
