Background
With the development of oil and gas resources in China gradually moving to deep water and marginal oil and gas fields, underwater production systems are widely applied and are key to ocean oil and gas development and production in future. Because subsea production systems generally have the need for ball and pigging, a pigging interface is usually reserved on a subsea production facility (e.g., a subsea manifold, subsea pipeline terminal equipment). However, if a newly-built underwater production system is developed by relying on an existing underwater production system, the newly-built underwater production system needs to be returned to the existing underwater production system through the reserved pigging interface, so that the existing underwater production system loses the pigging interface. In addition, because ethylene glycol needs to be injected into the submarine pipeline in the pre-debugging process of the newly-built underwater production system, if the built underwater production system does not stop production, slug flow is likely to occur after a large amount of ethylene glycol enters the built submarine pipeline in a short time, and adverse effects are brought to the normal production of the oil and gas field.
